Bayern Munich confirmed Eric Dier’s departure from the club
and they could also be without another center-back for the majority of the upcoming season
Kicker report that the return date of Hiroki Ito could be pushed until the start of 2026
The Japanese international suffered a second metatarsal fracture injury in the home game against St
The first incident came during the pre-season as he only made his return following a lengthy absence in his debut season at Bayern
Recovering from a concurrent serious injury will be a huge challenge for the former VfB Stuttgart all-rounder
Bayern want to handle the situation with extreme caution
Bayern’s sporting director Christoph Freund will be expected to add defensive reinforcement this summer (or possibly for the Club World Cup)
“We now have to monitor the injury situation – exactly how long Hiroki Ito will be out,” responded Freund when asked about a potential active involvement in the transfer market.

Aoi Ito, who has drawn attention for her unorthodox game style, opted to compete at home instead. The 20-year-old made the 2024 Osaka semifinals on her WTA debut, and was also the Canberra WTA 125 champion in January. Her semifinal run at the Tokyo ITF W100 two weeks ago has enabled her to break into the Top 100 for the first time, inching up one place to No. 100.
Australian Open junior champion Wakana Sonobe caused a splash on her WTA debut in February by qualifying and reaching the second round of Abu Dhabi. The powerful 17-year-old collected her first pro title two weeks ago at the Tokyo ITF W100 and roars up 161 places from No. 448 to a new career high of No. 287.
Three Ukrainians delivered career-best performances in Madrid. In nine previous appearances, Elina Svitolina won only three matches at the tournament -- none consecutively. She made up for lost time with a run to the semifinals, extending her winning streak to 11 following her Rouen title run three weeks ago and Billie Jean King Cup action the week before that. The 30-year-old is up three spots to No. 14, her highest ranking since October 2021.
Marta Kostyuk made her second WTA 1000 quarterfinal of 2025 in Madrid with wins over Emma Raducanu and Veronika Kudermetova. Having dropped out of the Top 30 two weeks ago for the first time since March 2024, Kostyuk immediately rebounded with a nine-place jump to No. 27.
Last October, Yuliia Starodubtseva broke into the Top 100 after reaching the Beijing quarterfinals as a qualifier -- only to lose 16 out of her next 19 matches, including all six at tour level. The 25-year-old ended her dry spell in style, once again as a qualifier at a WTA 1000 event. Starodubtseva made the last 16 in Madrid, notching her second Top 20 win over Liudmila Samsonova in the third round, and climbs 19 places to No. 80.
Former No. 79 Dalma Galfi has been quietly putting together a hot streak at WTA 125 level. The 26-year-old -- a former junior No. 1 -- was runner-up in La Bisbal d'Empordà four weeks ago, then followed that with her first two WTA 125 titles in Antalya and Vic. After compiling a 14-1 record over the past month, Galfi rises 26 places to No. 95 this week, returning to the Top 100 for the first time since June 2023.
Fellow Hungarian and former No. 50 Anna Bondar was also a title-winner last week, lifting the Wiesbaden ITF W100 trophy for the second time. The 27-year-old climbs 13 places to No. 89.
Jasmine Paolini, +1 to No. 5: The Italian made the third round of Madrid, and returns to the Top 5 for the first time since February.
Diana Shnaider, +2 to No. 11: Playing her second event with former No. 1 Dinara Safina as her coach, Shnaider won consecutive matches for the first time since January to reach the Madrid fourth round. The 20-year-old moves to a new career high.
Anna Blinkova, +9 to No. 67: Blinkova qualified and reached the second round of Madrid, where she delivered a strong performance against eventual champion Sabalenka.
Yuan Yue, +10 to No. 93: After losing 10 of her first 13 matches of the year and falling out of the Top 100 in March, former No. 36 Yuan ended her dry spell with a title run at the Oeiras ITF W100 two weeks ago -- her first career trophy at any level on clay.
Mananchaya Sawangkaew, +8 to No. 105: The 22-year-old Thai player moves to a new career high after reaching the Gifu ITF W100 final last week.
Rebeka Masarova, +41 to No. 112: Former No. 62 Masarova lost seven out of her first 10 matches of 2025, but has been resurgent over the past two months. Since March, the 25-year-old Swiss player has compiled a 16-5 record; in the last fortnight, she reached the Madrid third round as a qualifier then followed it by a run to the final at the Vic WTA 125.
Iva Jovic, +21 to No. 120: The 17-year-old American claimed her first ITF W100 title in Charlottesville two weeks ago, and is lifted to a new career high. Her clay-court results this year have earned her the USTA's reciprocal wild card for Roland Garros.

The Delhi government's PWD will lay two new drainage lines ahead of the monsoon to address waterlogging in the ITO area
Two new drainage lines to address waterlogging in ITO area
say Delhi PWD officials The drains will carry excess rainwater away from waterlogging-prone spots
A 600-millimetre pipeline will be laid from the Indraprastha Gas station up to Chatt Ghat opposite the Delhi Secretariat to address waterlogging on the Ring Road stretch near IP Estate and the ITO red light under the Indraprastha flyover
These areas have witnessed repeated waterlogging even after light rain during the past few years
Another 450-millimetre pipeline will be laid from the Indraprastha police station
to address waterlogging at the Tilak Bridge underpass
the Pragati Maidan tunnel and the ITO area
"We are laying two pipelines to address waterlogging in the area
The high-pressure pipelines will be around 600 metres in length," a senior public works department official told PTI
The PWD is also remodelling drain No 5 that runs from Azad Bhawan to IP Estate
has a separate pumping station with four permanent pumps
Drain No 5 has its outfall into the Yamuna under the Delhi Metro's Indraprastha station
Due to lack of proper desilting of regulator drain No 12 causing backflow and blocking the passage for excess rainwater
there was waterlogging on multiple occasions in ITO and adjoining areas last year
"Both works have to be completed in two months and we have floated tenders," the senior official said
The IP Estate and the Ring Road areas were waterlogged after the May 2 rainfall
with the government saying they were cleared within a few hours using super suction machines
PWD Minister Parvesh Verma has appointed assistant engineers and engineers as local in-charges for all 335 waterlogging points identified in the past few years
They are tasked with ensuring all necessary preparations are completed before the monsoon

After eight years spent focusing solely on the award-winning Royal Sushi and Izakaya in Queen Village
one of Philly's best chefs is about to double down
I wrote about Royal back in 2017
at the point when chef Jesse Ito (who ran the omakase nightly with his dad
Massaharu) was just beginning to collect a long string of James Beard Award nominations (seven at last count)
It was my favorite review in what was kind of a bleak run of technically-impressive-but-way-too-safe big-name openings in and around Philly — a weird
lagging year in our perpetual boom where it seemed like everyone had a restaurant (or two
but they were all versions of the same restaurant
Royal was nothing like any of them
It served unapologetically Japanese bar food in front — monkfish liver with yuzu
shumai with hot mustard — to an AC/DC soundtrack and anime projected on the wall
Jesse and his father presided over a handful of seats that were among the hardest in the city to get
Then came the pandemic. Then came complications. Jesse (who’d started cooking at Fuji, his parents’ restaurant in Cinnaminson, at 14), scaled back, switched to takeout, got sober, and talked about all of it with Hannah Albertine in a great interview back in 2022
It was in that same interview that he teased “a couple things that I’d be passionate about,” but swore he wasn’t looking to expand
That he was just focusing on staying clean
and focusing on himself and his life for “the next few years.”
“The name just came to me,” according to Jesse
and it’s a little bit inspired by ’80s Japan.”
So basically right in the center of my geeky little food-nerd heart
will be leading the kitchen at dancerobot (where he’ll also be a partner)
and while the menu is (obviously) still coming together
hamburger steak with demi and wasabi mashed potato
and mentaiko pasta — which is kinda like a Japanese interpretation of American comfort food
butter and soy sauce and you’re in the ballpark
making it one of the very few restaurants offering Japanese breakfast foods like teishoku
they’re looking at a spring (or possibly summer) opening in 2025
And you can be sure that I’m going to be keeping a close eye on this one as it progresses

I will express my gratitude to the people who have made me who I am today,” Ito told Variety
I’ve always wanted to make a film that reflects his narrative,” said producer Go Wakabayashi

Seven & i Update: Outlets Report on Possible CEO Change
The founding Ito family of Seven & i Holdings, 7-Eleven’s parent company, has failed to secure the money to buy it out, the company said Thursday. The announcement comes months after the family launched a bid worth over $50 billion, reported The New York Times
an executive at Seven & i and the son of its founder
the family’s asset management company
The outlets reported that the leading contender to be the new CEO is said to be Stephen Dacus
“The battle for control of 7-Eleven reflects the sweeping changes underway in corporate Japan, where the convenience store chain is considered a national treasure, making any foreign-led takeover a long shot. Japan has long been regarded as impenetrable for foreign companies seeking mergers and acquisitions,” wrote the NYT.
NYT wrote that Seven & i has said Couche-Tard’s proposed buyout would trigger competition investigations in the United States, where 7-Eleven and Circle K are the two leaders in store count. In its statement on Thursday, the Japanese company said it was working with Couche-Tard to determine if a proposal that addressed this regulatory issue was possible.
The upcoming March issue of NACS Magazine will include the latest c-store counts in the United States. 7-Eleven and Circle K combine for more than 17,000 U.S. locations.
nothing fits the bill like the haunting work of Junji Ito
An artistic visionary whose stories have terrified readers around the world
Junji Ito has made his mark on the horror genre
It’s only fitting that his creations have been brought into The Fog
and the Junji Ito Collection features 8 chilling Outfits inspired by some of his most iconic and unsettling characters
We recently had the honor of connecting with Junji Ito
who reacted to seeing his outfits realized in Dead by Daylight
and take a look at everything coming with the Junji Ito Collection
She hunted her prey and cherished their torment
Her jaws unhinged as she devoured a group of hapless filmmakers deep in the woods
The last thing her victims heard was her joyous
Though her body had been torn to pieces countless times
those pieces always grew into her duplicates
she would do anything to get what she wanted
Their mother found an abandoned cabin deep in the woods
Their long-needed rest was interrupted when Charlotte heard whispers coming from beneath the floorboards
Her mother's eyes widened as she grabbed Charlotte's arm and dragged her outside
*From multiple stories from Soichi’s Convenient Curse
Young Ji-Woon slid his finger over his blade
He watched one of the waitresses taking orders
The crowd went wild as he juggled his blades and threw a knife at the waitress
and Ji-Woon gestured for her to take a bow
until the screaming echoed from his memory
Growing old had been a blessing and a curse
He wailed at the sight of those he left behind
so deep in thought that she didn't notice her grandmother suddenly sitting next to her
Her grandmother understood that Yui would rather be out racing scooters than sitting in class
She stressed the importance before offering Yui her grandfather's motorcycle manuals – another form of education
The sudden death of an up-and-coming pop idol rocked the entire music industry
she wondered why death seemed to be following her
Yun-Jin put on the late singer's final album
The change in Ji-Woon's music was upsetting enough
Her mother convinced her that if she liked music
The teacher was strict and didn’t give the students any space to understand the method to her madness
Kate knew she was going to let her mother down
Kate told her mother that ballet was nothing like singing or playing guitar
we recently had the honor of sitting down with Junji Ito
who reacted to seeing his creations in The Fog
It’s always a momentous occasion when a legend of the horror genre makes their mark in Dead by Daylight
and we can’t wait to see the Junji Ito Collection in action

Olaf College Professor of Asian Studies Rika Ito will deliver the 42nd annual Mellby Lecture on November 21 in Viking Theater
Her lecture, titled “The Role of Language in Reproducing Imagined ‘Others’: Critical Views from Anime and Manga,” will begin at 11:30 a.m. It is free and open to the public, and will also be streamed and archived online
The lecture will blend Ito’s background in sociolinguistics to analyze popular media
showing how anime creators construct a “virtual reality” by emphasizing or downplaying linguistic and visual clues to differentiate “normal” people from “outsiders” like dialect users
is a key place where these value judgments are embedded as ‘entertainment,'” Ito says
noting that they can create and perpetuate stereotypes in viewers’ minds
Her latest project on an anime series titled Golden Kamuy explores Ainu representations
Ainu are an Indigenous group that mainly inhabit the island of Hokkaido in Northern Japan
as well as northern parts of mainland Japan and Sakhalin
Ito noticed that despite featuring an Ainu co-protagonist and Ainu culture positively
the show still portrays Ainu as a “dying race,” the discourse prevalent in the early 20th-century Meiji Japan
“The Ainu as a dying race discourse is reproduced in the anime show by contrasting between monolingual/bilingual characters
where the young bilingual Ainu woman is seen as modern
while the older monolingual Ainu woman is portrayed as stuck in the past,” Ito says
“I hope students and colleagues begin paying closer attention to how media represents the contrast between ‘good’ and ‘bad,’ even when it’s presented as mere entertainment
I want them to start questioning why certain things seem ‘normal’ and consider whose perspective defines that norm
It’s crucial to be aware of our biases when interpreting visual and linguistic representations in media.”
She believes it’s essential to foster awareness of the dangers and divisive discourses these biases create
The narratives embedded in entertainment play a big role in shaping perceptions and reinforcing stereotypes
“I hope a broader community audience will understand this topic because it raises awareness of our biases when interpreting what others say and
Language is a fundamental part of everyday life — talking
Ito hopes students pay attention to the messages the media is sending
“I hope students and colleagues begin paying closer attention to how media represents the contrast between ‘good’ and ‘bad,’ even when it’s presented as mere entertainment,” Ito says
“I want them to start questioning why certain things seem ‘normal’ and consider whose perspective defines that norm

Zeynep Sonmez | Aoi Ito
When Hsieh Su-wei, tennis' queen of unconventional artistry, announced her retirement from singles at the start of 2024, it was a bittersweet moment for fans who admired her distinctive style and creativity on the court. Now 38, Hsieh had seemed like one of the last holdouts against a full takeover by well-drilled, conveyor-belt baseline power.
But in October, a new hope emerged. Aoi Ito, an unheralded 20-year-old from the Aichi prefecture of Japan who had skipped most of the junior circuit, came through qualifying to reach her first WTA main draw. Armed with an effortless mix of precise slices, sharp angles, and delicate touch, Ito defeated Sofia Kenin, Elisabetta Cocciaretto and Eva Lys on her impressive run to the semifinals.
This year has been anything but a fluke for Ito. She posted an impressive 67-25 record, climbing from No.417 at the end of 2023 to a career-high No.127. She's scheduled to play her first Grand Slam qualifying event at next month's Australian Open.
Ito, who communicated via email this month with translation help from her mother, Sayaka, shared insights into her unique playing style, her view of tennis as a role-playing game and her knack for frustrating opponents. Get to know her story below.
You had an amazing WTA debut in Osaka. What are your favorite memories from the tournament? How much confidence has it given you?
Ito: Actually, I didn't expect to get a good result in Osaka. I am really happy I got into the main draw, then got into the semifinals. It was so exciting to play in front of many spectators. My play-style is tricky. Through this tournament, I am more confident that my play-style can be world-class.
In Osaka, you joked that your goal was to win only two games in the first round, then four games in the second round, then six games in the quarterfinals. Do you find it better to play when you're the underdog or the favorite?
Ito: I think I am a person who can think negatively. If I set a goal too high, I will lose my motivation and give up easily. So I like to be the underdog. But just be careful, I will sometimes bite! 🤣
Last month, you backed up your Osaka run by reaching the Hamamatsu ITF W35 final and then winning the Takasaki ITF W100 the following week. You did this despite a scary injury in the Hamamatsu final -- was it difficult to recover?
Ito: Yes, I hit my head against my racquet when I fell down. It bled a lot! I went to the doctor next day. He advised me to have stitches. But I turned that down immediately as I really hate pain. Luckily, the wound closed in a few days. So there was no impact on the Takasaki tournament.
What aspect of your game have you improved the most this year?
Ito: I think my forehand slices have improved the most. I can use them for both defense and attack.
Ito: My parents played tennis just for fun. My sister, who is four years older, played first. It was a routine to play tennis on weekends with my family. So I started to play tennis naturally when I was 5 years old. I've never really been to any tennis tournaments as a fan. I like to play, but I don't like watching so much.

You're also so nonchalant on court -- is it important to stay smiling and relaxed
So I always look for the technique to win against a better player
That's why I use various shots to control a match
The most important thing is tactics for me
I might as well have fun if I am going to do it
I feel like I am playing a tennis video game when I play in real life
is it extra important to have people behind you who believe in you
Ito: My father was a prosecutor; he is my coach now
So my father teaches me tactics in tennis and my mother supports me with various things like making arrangements for tennis trips
My father only played tennis for fun when he was young
I don't care at all whether I play like everyone else or not
All my family enjoys the process of getting my ranking up
you don’t feel pressured and you can enjoy the tennis life
Can you remember the first time you watched her play
My father loves her play-style and he often told me about her when I was young
I'd like to meet her someday and ask her what she thinks about my play-style
What do you feel when you see your opponent get frustrated
I just learned by myself so it's all my own style
Does your love of strategy games like Othello and Mahjong reflect your strategic approach to tennis
just like in tennis -- so I just keep trying and trying and trying
Which WTA player would you most like to play
Ito: I have no special player I want to have a match with
I think my play-style will evolve by playing with various types of players
Note: This article was published following Aoi Ito's second-round win in Osaka
She has backed that up by beating Eva Lys 6-7(8)
Aoi Ito's WTA debut this week at the Kinoshita Group Japan Open has been eye-catching in more ways than one
Osaka: Scores | Draws | Order of play
The 20-year-old Japanese qualifier has delivered two impressive upsets to book her place in her first tour-level quarterfinal
she overturned a 5-2 third-set deficit to stun former Australian Open champion Sofia Kenin
6-3 win against No.8 seed Elisabetta Cocciaretto
following her ITF W50 title in Nanao three weeks ago
The way Ito has been pulling off those wins has been pretty unconventional
Her game is an unorthodox mix of nonchalant forehand slices
sneak net attacks and changes of speed and direction that catch her opponents off guard
she chipped forehands deep in the court then
Cocciaretto's frustration at getting tied up in Ito's web of spins was visible throughout the match
Ito’s style puts her in the same category as past non-conformists like Monica Niculescu and Hsieh Su-Wei. It’s fitting, then, that back in 2022, while still in high school, she shared with The Digest how much she drew inspiration from Hsieh’s unconventional game
"The player I admire is Hsieh Su-Wei," Ito said
Ito expanded on how she developed her style
so I try to compete by technique," she explained
While Ito is thrilled to be holding her own at the tour level
keeping her expectations modest has served her well this week
she shared in her on-court interview that her goal against such a formidable opponent had simply been to win two games per set
She plans to stick to this approach heading into her quarterfinal match against lucky loser Eva Lys
I tried to get two games," she said after her win over Cocciaretto
her goal for the semifinals was "to get eight games."

the making of Shiori Ito’s feature debut, Black Box Diaries
A riveting portrait of the journalist’s pursuit for some semblance of justice after her sexual assault by powerful colleague Noriyuki Yamaguchi
the film also broadly critiques Japan’s deeply ingrained rape culture
which entailed sifting through troves of Ito’s intimate video diaries
courtroom footage of the lengthy legal battle against her assailant
covert recordings of a guilt-ridden detective and
devastating CCTV footage that shows a clearly inebriated Ito being carried by Yamaguchi into his hotel.
Ito also spurred Japan’s own #MeToo movement; her bravery in the face of sexist oppression—which at several points directly threatened her life—empowered a large swath of women to come forward with stories of their own “black boxes.” Though she is no longer living and working in Japan (“there are so many trolls,” she exasperatedly sighs at one point during our interview)
the fact that distribution has been nearly impossible to secure in her country of origin has been the final sticking point on Black Box Diaries’ otherwise successful festival and theatrical run
Ito will be accepting the Best Emerging Filmmaker honor at IDA’s Documentary Awards next month. Black Box Diaries has also secured three nominations
Ito finally has breathing room to think ahead—and even reminisce—in regards to her career
the 30-year-old is simply looking forward to eventually “creating a new film that is not about my story” and getting back to her roots as a story-driven
the documentarian reflects on her first encounter with culture shock
how the doc’s impact campaign has continued to evolve
and a particularly transcendent experience of swimming nude in a historic hot spring
DOCUMENTARY: What influenced your desire to study journalism and eventually become a reporter?
SHIORI ITO: I loved The Lion King when I was growing up
I always dreamed of going to the savanna to report on animals
When I went to this little school in the hospital
it was the first time I was able to let go of that strictness
That experience is what made me want to see if I could do something outside of Japan
I realized that my classmates didn’t even know where Japan was
I realized that information can shape people
I felt that it was important work to open people’s minds
and I have wanted to be a journalist ever since.
D: Your case resulted in Japan changing its archaic rape laws
but I’m curious if you and your team developed an impact campaign for the film itself?
but this is the first time someone has asked that
We are now focusing on [working with] the European Union and U.N
one of the biggest sexual violence survivors support groups
We also hope that we can also reach back to Japan to highlight what we need to change
Because our rape law has been very outdated
has always given the nudge that we need to change
I believe this film can open up the conversation
so it’s really important to do an impact campaign together
but we are heading back to Europe in November
I’m really excited to see what comes of it
D: I read that you’re eyeing a potential 2025 release for Black Box Diaries in Japan
Are there any updates on this front?
I feel more like distancing myself because there are so many trolls
some media outlets are writing that since I use CCTV footage
I had to pay the Sheraton Hotel about $4,000 to get the footage so they could blur out everyone
It’s really hard seeing every day how difficult it still is to talk about this issue in Japan.
D: Speaking of work that you have released in Japan recently
Can you explain the premise and what prompted you to write it?
SI: Writing this essay was a key element that supported me to direct my own film
When I wrote Black Box as a book
I only could write it from a journalistic point of view
so I didn’t know how much was okay to share
Editing took four years because I always clashed between a journalistic and survivor’s point of view.
This book is a short essay about the difficulty I went through making this film
but also about everyday life living in Japan as a woman
The name comes from the time that I experienced swimming naked in Japan
and there’s this amazing island between the main island and Okinawa called Yakushima Island
It’s very volcanic and has a hot spring right next to the ocean
people were giving me all of these labels: victim
I had to let it go because I have no control over what people call me
It was a dark night and I just felt like a living creature
It kind of goes back to the memory I had in the hospital
Now I’m always seeking to swim naked in different places of the world
That experience gave me the mindset I needed to finish this film
D: Do you think that you will revisit Japanese social issues anytime soon
Is there a specific aspect of the culture that merits further exposure and critique?
SI: This is just the tip of the iceberg of the systematic society that we are portraying in this film
There are so many other stories that have to be told
I don’t think I can work as an investigative journalist anymore because I’m way too exposed
But I have to use this exposure to highlight issues from outside
because the Japanese media is afraid to talk about these things
I wish that I could shake up Japanese journalism in general
It makes it harder for me to go back to Japan
though I don’t know how many years it will take
we’ll see how necessary it was to talk about all of this.
D: You’ve been on the festival circuit for Black Box Diaries since it premiered at Sundance back in January
I’m assuming this means that you haven’t had a ton of time on your hands to begin work on
SI: I just can’t wait to start creating a new film that is not about my story
I realized that every community has a “black box.” Through this film
I just really want to open up to the audience to start thinking
“What’s my black box?” Of course I have a journalistic background
I’ve been carrying around a recorder to try and make a podcast asking people about their black box
But I’ve heard so many people start thinking about how they want to tell their own story

Bayern Munich defender Hiroki Ito has suffered another injury setback during his recovery from a broken metatarsal
Ito, 25, joined Bayern from Stuttgart in July 2024 for €23million ($24.7m)
but suffered the injury in a pre-season friendly against FC Duren and is yet to play a competitive game for his new club
Ito had returned to training at the beginning of October and had provisionally been expected to make his competitive debut after the November international break
“The defender will have to take a break for the time being and will start his rehabilitation program again as soon as possible,” the club announced
Speaking in his press conference ahead of Bayern’s Champions League tie against Benfica
head coach Vincent Kompany expressed his disappointment
“Then he will definitely get back to his best level
In more positive news for Bayern, the club have announced midfielder Aleksandar Pavlovic
who suffered a broken collarbone against Stuttgart in early October
Pavlovic has begun running again and is expected to be available before the end of the year
The 20-year-old has made nine appearances in all competitions this season
Bayern face Benfica in the Champions League on Wednesday before travelling to St Pauli on Saturday
Are Bayern Munich any good under Vincent Kompany

When artist Chris Domenick stood in the monumental Main Gallery of the Ezra and Cecile Zilkha Gallery
he observed the way light from the building’s windows worked with his new installation
“It’s so cavernous and incredible and the light is so amazing,” he said
The moment marked a milestone—his first solo institutional exhibition, Private Figure
a show that combines floor- and ceiling-based lamps with wall works by the artist
Wesleyan University’s home for contemporary art since 1973
is known for encouraging artists to take risks that may not be as welcome at more traditional gallery spaces
For Curator and Associate Director of Visual Arts Benjamin Chaffee ’00
“I am really looking for the gallery’s program to tell a story that is as broad as possible about who can be an artist and what art could be,” Chaffee said
the gallery hosts two exhibitions that explore the boundaries of painting and sculptural installation
Within Domenick’s Private Figure
his sculptures are lamps that behave like designed objects while also blurring the line between sculpture and painting
The artist reimagines each of the frames around his wall works as sculptural gestures
“It begins to bring the frame and the making of the work into one realm,” Domenick said
“Because it becomes sort of like a sculpture
It’s almost like you get to learn from the wall works how to look at the lamps.”
Installed in Zilkha’s North Gallery is Parker Ito’s A Lil’ Taste of A Lil’ Taste of Cheeto in the Night
a reimagining of a painting first exhibited in Los Angeles a decade ago
Ito’s approach to artmaking is very collaborative; his painting People tell me everyday that I’m really creative (peace on earth) (A Lil’ Taste of Cheeto in the Night Installation) (2013–2015) began as an Adobe Photoshop collage and was outsourced to China for painting before being completed back in his studio with various additional painted layers
“The way I’ve always described it is a kind of ‘style as content,’” Ito said
“It’s just about the aesthetic.”
When Chaffee brings two artists like Ito and Domenick together
he is curating two simultaneous solo exhibitions that he hopes viewers can engage with on many different levels
“I think a lot about the reference points that a viewer might bring into the gallery and how those intersect with the references that each artist’s work already contains,” Chaffee said
“Then I consider how each exhibition might either contrast with
or build on the discourse of what has been shown in the gallery in the past
I believe that every past exhibition and artwork still exists in the space as a kind of ghost.”
that dialogue extends beyond the walls of the gallery
he shipped a bronze sculpture—Western Exterminator / Kernel Kleenup / Little Man / Pesterminator (automotive pink) (2013–2015)—from Los Angeles during the Southern California wildfires in January
integrating it into a larger installation of LED lights and 500 feet of chain that frame his double-sided painting hanging from the gallery’s ceiling
“This is a more minimal presentation of the installations I was doing from that time,” Ito said
“It is well suited for this space because it’s so vertical and so tall
I don’t know if I’ve ever done one in a space this tall before.”
Chaffee sees the Zilkha Gallery as a place where such risks and reimagining of works are not just welcomed but encouraged
“We’re not a collection space,” he said
“We build projects with artists.”
that spirit of collaboration and experimentation is what makes their exhibitions at Wesleyan so meaningful
“The Zilkha Gallery has a long history of supporting artists to develop installations in response to the unique architectural space within the dynamic intellectual liberal arts community of Wesleyan,” Chaffee said
I try to extend invitations to artists who will not only appreciate this opportunity and rise to its challenges
but also build on the history of past exhibitions
they’ll make a more interesting show
Can we find that place where everybody can benefit?”
Private Figure and A Lil’ Taste of A Lil’ Taste of Cheeto in the Night are on display through March 2. Learn more at www.wesleyan.edu/cfa/zilkha.

We report on the experimental demonstration of temperature insensitivity in an epsilon-near-zero (ENZ) indium-tin-oxide (ITO) cladded
The permittivity of the ITO cladding was engineered to a near zero value at 1550 nm wavelength to support index guiding in the air-ITO waveguide around the C band
The air-ITO ring-resonator structure was designed using numerical simulations to support whispering gallery modes
The hollow-core microresonator structure was fabricated using two-photon lithography to 3D print a sacrificial scaffold
Guided resonator modes were observed by coupling tunable laser light to the ring resonator using a tapered fiber
The demonstrated hollow-core microresonator exhibits athermal behavior and has a temperature dependent wavelength shift of 1 pm/°C
One limitation of these systems is that the oscillator requires a very high quality factor (Q) cavity which is inherently susceptible to environmental perturbations such as temperature variations and vibrations
This can cause the generated frequency to drift with time unless the oscillator is isolated from environmental interference with extensive housing
The high SWAP-C of these devices restricts their widespread adoption
particularly in smaller portable device applications
These are complex devices that perform the tasks of laser cooling
there is an inherent increase in complexity when including atomic sources on chip
This would eliminate the need for high SWaP-C environmental isolation housing and the atomic source
One downside to this approach is that the devices are subject to tight fabrication tolerances and the TOC will be near zero for only a small wavelength range
Devices can be engineered to operate within a large wavelength range due to the easy tunability of the ENZ regime of ITO
air core design will extend over a larger wavelength range than the layered hybrid structures since light is predominantly confined in the low TOC core anywhere the cladding index is lower that the core index
reduced thermal sensitivity of the resonant wavelengths in an ENZ clad
air-core MRR is expected since most of the resonant optical mode will be in the low TOC core and not in the cladding
we report the design and fabrication of an ENZ-ITO clad
hollow-core resonator and demonstrate the athermal behavior of the device within and around the C-band wavelengths
This device exhibits its athermal behavior due to light confinement in the hollow-core by the ENZ ITO cladding layer
Since ITO is a common material used in semiconductor processing
this work paves the way for developing an intrinsically temperature insensitive cavity that can be integrated with PICs
This device also demonstrates the potential of 3D printed optical devices and this method could be applied to other complex structures to allow for different mode confinement and dispersion control
SEM image of a resonator after IP-Dip removal
SEM image of the cross-section of a straight line structure showing the IP-Dip removal
The IP-Dip was left in to prevent damage to the cross-section geometry during cleaving
Overlaid on the cross-section is the guided mode found from COMSOL simulation
The spectroscopic ellipsometry of the ITO film is shown with a grey band indicating that ε1 and ε2 are in the ENZ regime over the entire tested wavelength range
The lighter color red and blue indicate the top layer
air exposed side of the film and the darker colors indicate the bottom layer substrate side
The intrinsic Q (black line) with the real (blue line) and imaginary (red line) parts of the effective index as a function of wavelength
\(d = 2\pi \left( {radius} \right) \cdot n_{{eff}}\) is the round trip distance
and \(\mathcal{L}\) is the round trip fractional loss:
The intrinsic Q peaked above 6000 at 1498 nm which corresponds to where ε1 of the inner layers of the ITO cladding crosses zero
the waveguide has the highest index contrast between the core and the cladding
the guided mode confinement in the air core is maximized
At lower wavelengths the index contrast is lower so more of the mode leaks into the cladding and loss increases
At higher wavelengths the ITO begins to act more metal like which causes more absorption loss
This analysis shows that with proper tuning of the ENZ property a device could potentially achieve a Q of 6000 or more
It is likely that the values of ε1 and ε2 of the ITO cladding of the fabricated resonator differ from those of the ITO on the substrate where the ε1 and ε2 in Fig. 2b were measured
This is because the annealing parameters to achieve the proper ENZ condition are dependent on film thickness and interface materials which varies around the sides of the resonator and the fact that the ITO cladding is elevated which would change the annealing rate
The experimental setup can be seen in (Fig. 3). The sample was mounted onto a thermo-electric cooler (TEC) which was then mounted onto a manipulator arm. Light was coupled into the device using a tapered fiber. This setup is described in more detail in the Methods.
The microring resonator was mounted onto a manipulator arm and then brought into range for coupling with the tapered fiber
A magnified image of this can be seen in the inset
Experimental results of coupling light into the resonator
The transmission spectrum obtained by evanescently coupling the resonator to the tapered fiber
A baseline measurement was performed before the coupled measurement and subtracted from the coupled spectrum
Demonstration of the athermal property of the resonators
The transmission spectra at different temperatures
The resonant dip location at each temperature for the resonance at 1578 nm (boxed in blue in a)
A linear fit of these points shows a TDWS of ~ 1 pm/°C (blue line)
Also shown is the TDWS of a Si resonator for comparison (black line)
This variation is likely due to two things
the tapered fiber positioning is perturbed during the temperature sweeps which will affect the measurements and ultimately add uncertainty to the peak positions
mode confinement decreases at wavelengths further from the ε1 = 0 point
This means more of the light travels through the ITO cladding which does not have very low TOC and the TDWS will have a slightly increased temperature dependence
The discrepancy between our measured loaded Q (700) and the estimated high intrinsic Q (> 6000) indicates two things
we likely have high coupling loss caused by the ITO cladding material thickness and roughness that induces scattering
the ε1 = 0 point of the ITO cladding on the measured device is probably not at the wavelengths where we conducted the measurements
Improvements to this device could be made by optimizing the coupling mechanism and the cladding thickness
A thick cladding is needed for structural stability and improved light confinement
but this also makes it difficult to couple light into the core which increases the coupling loss
Optimizing the annealing procedure would also be beneficial and allow the effective index to be tuned so that the maximum intrinsic Q is achieved in the desired operating wavelengths
Other cross-sectional geometries may also increase the Q
there is a lot of room for improvements to be made to future devices
This approach to constructing an athermal optical resonator is intrinsically less sensitive to thermal fluctuations due to the hollow-core design
an air or vacuum core will have essentially no stresses and strains that would normally affect the refractive index of a core made from layered solid materials
This potentially would make the device less sensitive to other environmental perturbations such as vibration if the device can be embedded into a rigid material like SiO2
The device shown in this work proves the concept and further optimizations could increase the Q by an order of magnitude and allow it to lock a high-Q oscillator in a reasonable amount of time
Steps to fabricate the hollow-core resonators
The IP-Dip core is printed from a 3D CAD model using the Nanoscribe Photonic Professional GT2
A sacrificial Si layer is deposited onto the core
The substrate was mounted onto a rotating stage at an angle steep enough to ensure even coverage around the MRR and to make sure adequate coverage inside the drain channels
The ITO layer was then deposited in a similar way
but at a shallow angle to make sure the sacrificial Si layer was still exposed in the drain
The Si layer was removed with a XeF2 etch and then the IP-Dip core was ashed and removed via an annealing step
This final anneal step simultaneously processed the ITO to achieve an ENZ condition
Removing the photoresin core and processing the ITO films so they would have the appropriate optical properties were combined into one single annealing step
Post deposition annealing was done in an Allwin21 rapid thermal annealing tool
The annealing steps were done in a nitrogen environment with a N2 flow rate of 5 L/min at 650 °C
the sample was diced with a LPKF Protolaser U4 laser cutting tool in order to cut the substrate into sufficiently thin slices for measurement
This was needed so that enough clearance was present to allow the tapered fiber to come close enough to the microring resonators
All SEM images were obtained with a ZEISS™ Auriga SEM
We used an Agilent 8164A Lightwave Measurement System with an 81682A tunable laser and an 81633A Power sensor
The output power from the laser was 5 dBm and was swept over the wavelength range of 1530–1580 nm
The sample was placed into an isolation box with a continuous flow of nitrogen to prevent dust from settling on the tapered fiber and to minimize condensation on the sample during low temperature testing
The tapered fiber was made using a Thorlabs Vytran Automated Glass Processor (GPX-3800)
the sample was aligned to the tapered fiber and then brought closer for coupling
The power measured by the power meter was ~ -4.5 dBm for just the baseline tapered fiber measurements
This is mostly due to scattering of higher order modes in the tapered fiber

Samba Diawara provided a positive update on Junya Ito’s ankle injury earlier this week
the Japanese international is not expected to be fit to face OGC Nice
Stade de Reims head to the Côte d’Azur with the hope of getting a win that would potentially confirm their safety in Ligue 1
they will have to do so without their key player
The Japan international came off injured during the 0-0 draw against Montpellier HSC last weekend
There was a fear that Ito had suffered a serious injury
stating that the forward had not suffered a sprain
Diawara confirmed he would need a few days’ rest and so he misses Reims’ match against Nice on Friday night

Aoi Ito got her 2025 season off to a perfect start by winning the first WTA 125 title of her career at the Workday Canberra International on Saturday. No.7 seed Ito of Japan defeated Wei Sijia of China 6-4, 6-3 in a 74-minute final in the Australian capital.
Only eight spots in the PIF Rankings separate these two rising players, with Ito placed at No.126 and Wei slightly lower at No.134. Neither player dropped a set en route to the final.
Ultimately, it was 20-year-old Ito who eased past 21-year-old Wei to hoist the trophy. Ito had previously toppled No.1 seed and defending champion Nuria Parrizas Diaz 6-2, 6-2 in the semifinals.
In Saturday's final, Ito broke serve in the very first game, and she did not let up as she cruised to the one-set lead without facing a break point. Ito won 81 percent of her first-serve points (13 of 16) in the opening frame.
The Japanese player got off to a quick start in the second set as well, slamming an overhead to force an error and break Wei for a 2-1 lead. It was smooth sailing for Ito from there, who won the match on Wei's fourth double fault.
Ito did not lose her serve in the final. She now has a 3-0 head-to-head lead over Wei (6-0 in sets).
Inspired by the crafty play of former WTA Doubles World No.1 Hsieh Su-wei, Ito continues her rise towards the top of the game. She made a sparkling Hologic WTA Tour debut in October when she made her way into the Osaka semifinals as a home-soil qualifier.

Print When Shiori Ito alleged at a 2017 news conference that Noriyuki Yamaguchi
a prominent TV journalist and friend of Japan’s then-Prime Minister Shinzo Abe
had two years earlier drugged and raped her in a Tokyo Sheraton hotel
she hoped the revelation would spark media interest in her case
the young journalist was subjected to online trolling and so many threats that she vacated her apartment
a Swedish producer-director she’d met only via Skype
“I started feeling like maybe I needed to do something
my own investigation as a journalist but also as a survivor,” she says while sitting in a cushioned alcove at the Four Seasons Hotel
‘I want to make your documentary.’ And I didn’t want them to
She wrote a memoir about the trauma
which some credit with starting Japan’s #MeToo movement
while pursuing legal cases against Yamaguchi for much of that intervening period
“Black Box Diaries,” in which Ito uses everything she can think of — secretly recorded telephone conversations
confessional iPhone diary entries — to convey the personally bruising saga that unfolded after her alleged sexual assault
from the legal proceedings against her well-known offender to an examination of Japan’s archaic rape laws
Interspersed are scenes of Ito working on her memoir
The documentary’s bracing reportage reveals Ito’s gift for in-depth journalism and
having previously made only short TV documentaries
her resourcefulness as a no-budget filmmaker
“We never had a team — no proper cameraman
It’d be great if we could film more cinematically
it really helped because no one pressured us.”
that audiences might find it confusing that Ito occasionally recorded her iPhone diary entries in English instead of in her native Japanese
“We never even thought about it,” says Ito
adding that she thinks of English as a tool that assists her in voicing anger and frustration
I didn’t know how to put my emotions in Japanese
You act different when you speak English.’ That’s what language and culture can do to you.”
To get around potential liability in “Black Box Diaries,” Ito purchased grainy security footage from the hotel and let viewers see Yamaguchi struggling to haul her lifeless-looking body from the back of a cab, then later hoisting her up as she stumbles unsteadily through the hotel lobby.
A recurring figure in “Black Box Diaries” is a police investigator who, instead of helping a potential victim of a sex crime seek justice, offers excuses. But sometimes good Samaritans emerge. One memorable moment involves Ito’s phone conversation with a hotel doorman who had offered to testify on her behalf. “He remembered talking to police,” Ito says, and believing he’d be called to court for a criminal trial. After he saw on the news that the case was closing, he contacted her.
Over five years, Ito had amassed more than 400 hours of footage, but there was more to discover. A year into editing, “Black Box Diaries” editor and co-producer Ema Ryan Yamazaki discovered on Ito’s iPhone an anguished suicide message meant to be seen by her parents that Ito had no recollection of filming. That too made it into the documentary.
Since its Sundance premiere, “Black Box Diaries” has been shown at film festivals around the world, including in Hong Kong, where a long line of people waited to share with Ito, one on one, their own painful experiences. “On one hand, as a journalist, I really wanted to listen,” Ito says. “But on the other hand, I’m a survivor, not a therapist. I just had to find a way to cope.”
Not much later, she booked herself into a 10-day silent meditation retreat.

In an opening scene of “Black Box Diaries,” journalist Shiori Ito is talking into the camera in a video diary
“I have a chance to talk about the truth… which has been ignored,” she says
This previews the narrative style Ito shares throughout the Academy Award-nominated documentary
where she turns the lens on herself to investigate the man who sexually assaulted her
then a 25-year-old intern at Thomson Reuters
the Washington DC bureau chief of the Tokyo Broadcasting System for dinner to discuss a possible job opportunity
Ito recounts how she can’t remember anything from that night after suddenly getting ill during the meal
She only remembers waking up in a hotel room hours later to Yamaguchi sexually assaulting her
Ito went public about the assault and was met with vilification and backlash
only a few colleagues showed support and only one media outlet covered the story
Ito tried to piece together what happened that night and hold her rapist accountable as she sought justice
Ito recounts the traumatic ordeal in the nearly two-hour documentary released last year
“In this story I was a journalist and a survivor
I questioned myself many times whether it was okay to look into my own case,” Ito says
which found him liable for sexual assault despite his denials
The court also dismissed a counter-suit by him claiming defamation by Ito
Japan’s Supreme Court upheld a high court decision that there had been sexual intercourse without consent and directed Yamaguchi to pay her more than US$30,000 in damages

has resonated with audiences all over the world
In the lead-up to the 69th Session of the UN Commission on the Status of Women
partnered with the Japan Society to host a reception in New York City
and experts to discuss the film’s call to action in holding perpetrators accountable and supporting survivors of sexual violence
the film will help hold accountable corruption and abuse of power that is happening in many facets of society,” says Meredith Goldberg-Morse from MTV Documentary Films
“It’s also about empowering the next generation of women in journalism so that these stories continue to be told.”
only 4% of sexual assault cases in Japan are reported to authorities
Police were initially dismissive of Ito’s case
and after going through a humiliating reporting process — which included reenacting her rape with a life-size doll in front of police officers — she decided not to pursue charges
That’s when she realized she had to dig deeper to provide as much evidence as she could about what Yamaguchi had done to her that night. Her investigation gave life to an award-winning memoir, “Black Box,” and
Ito talked to GIJN about the investigative process involved in her reporting
the biggest question she faced was whether she could face this investigation as a survivor
She battled with the tension of working within the tenets of traditional
so-called objective journalism while also being the film’s main subject
“Sometimes because you are the subject and you are the closest
But Ito also acknowledges the extreme vulnerability of laying her trauma bare and not being a neutral
There are several scenes where she shows that vulnerability
including moments where she is reading hate mail as well as having derogatory names yelled at her outside the court
After eight grueling years of producing the film
Ito isn’t sure she wants to return to journalism
“I’ve been talking to my journalist friends
and we kind of started saying that we do need more personal perspective journalism,” Ito explains
we need more of a personal perspective investigative story
Collaboration was key to Ito’s investigative process when working on the documentary
“You need collaborators to edit,” she says
“Editors have a completely objective third eye
And for journalists working on a high-risk investigation
Ito emphasizes that collaboration is even more crucial
she says “international support was the lifeline for this documentary.”
She also emphasizes the importance of teamwork
especially in a situation where the story challenges local or cultural taboos about speaking out
In “Black Box Diaries,” Ito is in constant conversation and consultation with other journalists
“Always find possible international collaborators when topics are hard to talk about in your country,” she says
it was important to document the entire process
including collecting footage of her most vulnerable moments
so always record what’s happening around you,” Ito explains
we see her recording several conversations with the investigators and officials
often with the recorder hidden in her clothing
Ito doesn’t think she could have written the book or produced the film
Ito and other producers track down Itaru Nakamura
the chief of police who dismissed her case
the footage of Ito banging on his car window trying to get answers is a powerful testimony to a journalist’s relentless task of seeking answers and holding public officials accountable
“Because we had the journalistic background
we never stopped asking questions,” Ito says
the use of some recording in the film has also created legal challenges for her
with her former lawyers accusing Ito of using footage and recordings without permission from sources
On February 20, Ito released a statement apologizing to those featured in the documentary without their permission, according to a report by The Japan Times
She also mentioned that a new version of the film would be released where some sources would not be identifiable
When Ito published her memoir about the assault in 2017
many people said her experience helped spark the #MeToo movement in Japan
But writing the book was a lonely journey for Ito
who recounts the harassment that ultimately forced her to leave Japan
the collaborative process of putting the film together made the journey more tolerable
especially with the support of international producers
she tried to enlist other journalists in Japan who were willing to tell her story
but faced pushback from their editors who mostly feared retaliation by Yamaguchi
she felt like she had more agency over the production and editing process
Her goal in pursuing visual storytelling was for people to experience the story viscerally
“There are some things that are just hard to talk about in writing
that you can only bring out through documentary,” she notes
Ito encourages other survivors to use a storytelling medium they are most comfortable with
but to be flexible in exploring other reporting formats
As “Black Box Diaries” pushes towards the Oscars
rights groups are highlighting the timeliness of the film
“The film highlights why there are so many obstacles… why there are challenges with reporting sexual abuse in the workplace,” says Minky Worden
“We are going backwards when it comes to women’s rights
Ito’s reporting has pushed some policy shift
Japan raised the age of consent from 13 to 16
and expanded the definition of rape from “forcible sexual intercourse” to “nonconsensual sexual intercourse.” The law now includes victims who are impaired by alcohol or drugs
who are coerced by someone in a position of authority
and who are unable to voice their refusal due to being in a state of shock
In the final scene of “Black Box Diaries” Ito and a friend are in a car
singing along triumphantly to Gloria Gaynor’s “I Will Survive.” While her mood in the scene quickly shifts from exhilaration to sadness as she slumps in her seat
she says making the documentary was itself an act of defiance
“I want to encourage other survivors to tell their story in their own language
because it’s very empowering,” she says
“Own your story and be the one to tell your own story.”

To understand the complex dynamics of neural activity in the brain across various temporal and spatial scales
it is crucial to record intracortical multimodal neural activity by combining electrophysiological recording and calcium imaging techniques
This poses significant constraints on the geometrical
transparent flexible graphene–ITO-based neural microelectrodes with small feature sizes are developed and validated for simultaneous electrophysiology recording and calcium imaging in the hippocampus of freely moving mice
A micro-etching technique and an oxygen plasma pre-treating method are introduced to facilitate large-area graphene transfer and establish stable low-impedance contacts between graphene and metals
leading to the batch production of high-quality microelectrodes with interconnect widths of 10 μm and recording sites diameters of 20 μm
These electrodes exhibit appropriate impedance and sufficient transparency in the field of view
enabling simultaneous recording of intracortical local field potentials and even action potentials along with calcium imaging in freely moving mice
Both types of electrophysiological signals are found to correlate with calcium activity
This proof-of-concept work demonstrates that transparent flexible graphene–ITO-based neural microelectrodes are promising tools for multimodal neuroscience research
developing a unified tool integrating electrophysiology and calcium imaging would be invaluable
combining the strengths of each to achieve high spatiotemporal resolution in neural activity recording
substantially restricting the spatiotemporal resolution of neural activity recording
miniaturizing the electrode’s feature size to that of a single neuron is essential for capturing high-frequency electrical activity during calcium imaging
since the rigid electrodes were attached to the side of the lens
it remains uncertain whether the LFPs originated from the FOV
and the correlation between these potentials and the calcium signals has yet to be determined
This work reports the development and validation of small feature-size TFNMEs based on graphene–ITO (Gr–ITO–TFNMEs) for high spatiotemporal resolution in intracortical neural activity recording
Gr–ITO–TFNMEs employ ITO as the interface material for recording sites
with metals serving as the interconnects and graphene acting as a bridge between the ITO and metal interconnects
The configuration ensures that the FOV is composed entirely of transparent materials and incorporates graphene flexibility
decreasing bending caused fatigue or damage
A micro-etching technique is proposed to enable crack-free
and large-area graphene transfer through multiple alignments and transfers of small-area graphene
an oxygen plasma pre-treating the graphene method facilitates the stable
low-impedance contacts between graphene and metals
These technological advancements promote the batch production and high-quality fabrication of Gr–ITO–TFNMEs with small feature sizes (interconnect widths of 10 μm and recording site diameters of 20 μm)
The resulting Gr–ITO–TFNMEs exhibit an electrochemical impedance of 1.45 MΩ at 1 kHz and demonstrate an optical transmittance greater than 80% at 520 nm
the ‘watch-style’ Gr–ITO–TFNMEs are integrated onto the GRIN lens of the TINIscope system
simultaneously recording electrophysiological signals and performing calcium imaging in the hippocampus of freely moving mice
The integrated Gr–ITO–TFNMEs can stably and reliably record LFPs and action potentials
The power spectral density of LFPs and the number of action potentials showed correlations with calcium activity

j Representative calcium trace (top) and the spike raster plot (bottom) with the maximum correlation
which was obtained by traversing all neurons’ calcium peaks and the corresponding number of spikes
Fluctuations in the calcium trace are generally associated with intense spike activity occurring within brief periods; However
not all instances of intense spike activity lead to high peaks in the calcium trace
This discrepancy is speculated to be related to the location of calcium proteins
with spikes possibly occurring in regions lacking calcium proteins
We developed a powerful tool for multimodal neural activity recording and addressed the challenges in the application of TFNMEs from three main perspectives
This study is the first to combine graphene and ITO for multimodal neural activity recording
graphene serves as a conductive bridge between ITO and the metal interconnects
overcoming the brittleness of ITO and optimizing conductivity without compromising transparency and flexibility
this combination harmonizes the material used for the top and bottom insulation layers
thereby eliminating issues such as curling and delamination
The selection of all materials makes it less prone to failure when undergoing large angle bending to integrate with the GRIN lens
In applications where higher transparency is a priority
tensile strength requirements can be moderately relaxed
presents a suitable alternative as the insulation material
demonstrating the effectiveness of these techniques for fabricating high-quality electrodes containing graphene
it was restricted to recording cortical neural activity in head-fixed mice due to imaging limitations
We integrated TFNMEs with the GRIN lens to successfully record neural activity in freely moving mice and captured intracortical spikes with TFNMEs for the first time
the recordings were limited to spontaneous neural activity
demonstrating the potential of Gr–ITO–TFNMEs as a versatile tool for multimodal neuroscience research
Future work should aim to expand electrode density to record a broader range of high spatiotemporal resolution neural activities and incorporate behavioral testing to capture nonlinear neural dynamics
this study has proposed a new type of transparent flexible neural microelectrodes that can record intracortical multimodal neural activity in freely moving mice
the electrodes pave the way for further advancements in understanding the complex dynamics of the brain with high spatiotemporal resolution for multifunctional neuroscience research
this treatment facilitated the uniform and stable deposition of metals
low-impedance contacts were formed between graphene and metals
validated by measuring the impedance of short-circuited metal interconnects to graphene
(5) The graphene was patterned by reactive ion etching (RIE) with AZ-6130 photoresist as the etch mask
(6) A 140 nm of ITO was magnetron sputtered to form the interface of recording sites with a lift-off process using a 99.99% purity indium tin oxide target material (In2O3:SnO2 = 90:10 wt%)
The sputtering temperature was room temperature
The thickness of the ITO functional layer was 140 nm
The sheet resistance of ITO was measured using a four-point probe method and found to be 228 Ω/▫
(7) A 3 μm layer of PI was spin-coated and cured as the top insulation layer
and openings of recording sites were defined by RIE with AZ-4620 photoresist as the etch mask
(9) The entire silicon wafer was submerged in deionized water to release the electrodes
comparing three different types of electrodes: Gr–ITO–TFNMEs
and Au-based flexible microelectrodes (Au-FNMEs
The microbeads were first thoroughly dispersed in the PDMS crosslinker at a 1:500 ratio with ultrasonic treatment for 30 minutes
This microbead-containing crosslinker was mixed with the PDMS prepolymer at a ratio of 1:10
After stirring and degassing to remove bubbles
the mixture was spin-coated onto pre-cured PDMS blocks at 2000 rpm
The excitation wavelength of the microbeads was 488 nm
Male C57BL/6J mice were housed in a controlled environment with a 12-h light/dark cycle and ad libitum access to food and water
All animal experiments followed protocols approved by the IACUC (Institutional Animal Care and Use Committee) of Shenzhen Institute of Advanced Technology
Chinese Academy of Sciences (SIAT-IACUC-20221124-NS-NXXZX-ZDK-A2028-02)
were anesthetized with isoflurane vapor (2% for induction and 1–1.5% for maintenance) mixed with O2 and fixed on a stereotaxic apparatus
Body temperature was maintained at 37.5 °C using a heating pad during surgery and anesthesia recovery
AAV2/9-hSyn-GCaMP7s virus (Shanghai Taitool Bioscience) was injected into the dorsal hippocampus (dHP) at AP: −2.1 mm
DV: −1.4 mm from the surface of the skull with a 9° angle
A total of 400 nl of virus was injected at a rate of 15 nl/min
and the mouse was placed on a heating pad to facilitate recovery
electrophysiology recording and calcium imaging were simultaneously conducted in freely moving mice
The signals were sampled at 30 kHz and transmitted to the data acquisition equipment (NeuroStudio System
The electrical cables were connected to slip rings to avoid entanglement with the TINIscope system
a shielding mesh (100 cm × 80 cm × 120 cm) covered the system to minimize interference with electrophysiological signals
Calcium imaging was acquired at 12.5 frames per second by the TINIscope system
Electrophysiological signals and calcium imaging were synchronized by sending TTL pulses to Neurostudio and controlling the LED signal lights within the behavioral field of view
mice were sacrificed and transcranial perfused with saline followed by 4% paraformaldehyde (Sigma) in PBS
The brains were kept in 4% paraformaldehyde at 4 °C for 24 h and subsequently immersed in 30% sucrose for 72 h before being sliced into 40-μm coronal sections and imaged under a fluorescence microscope (Olympus MVX10)
which facilitated identifying individual neurons and the acquisition of neuron traces
Electrophysiological signals were analyzed and processed utilizing the Offline Sorter and NeuroExplorer software
To analyze the electrophysiological signal (LFP) and calcium signal correlation
we first identified the peaks in the normalized calcium signal (average calcium intensity)
we calculated the time-averaged LFP power spectral density around the onset times of these peaks
Pearson correlation coefficients were computed for each recording site to quantify the relationship between the calcium peaks and the average LFP power spectral density
The same procedure was applied to calculate the correlation between the calcium trace and the spike raster

Bayern Munich’s Hiroki Ito is set for another spell on the sidelines after suffering a metatarsal fracture for the second time this season
The Japanese defender picked up the injury in Bayern’s 3-2 win over St Pauli on Saturday
He came on as a substitute in the 58th minute and was forced off injured just over half an hour later
Bayern played the final stages of the game with only 10 players
having already used all five substitutions
It is another blow to head coach Vincent Kompany after injuries to defenders Alphonso Davies and Dayot Upamecano
Ito joined Bayern on a four-year deal in the summer from fellow Bundesliga side Stuttgart but sustained a metatarsal fracture in preseason. He underwent surgery twice and did not make his debut for the side until February 12 in a 2-1 in the Champions League play-off round
“The news of another serious injury to Hiroki hits us all very hard,” said Max Eberl
“He’s only just battled back after months of rehab and will now be out for a long time again – we can barely imagine how he’s feeling
He’ll get all the support he needs from us
He’s a fighter and we look forward to him being back on the pitch.”
Ito has only featured in eight matches at club level this season
He is set to miss an important part of Bayern’s season
which includes a Champions League quarter-final tie against Inter
The 26-year-old has 21 senior caps for Japan and was part of the squad that became the first nation outside of the three host countries to qualify for the 2026 World Cup in March’s international break
Bayern lead the Bundesliga by six points from second-placed Bayer Leverkusen
Kompany’s side return to action on Friday when they visit Augsburg
Analysis from German football correspondent Sebastian Stafford-Bloor
this will be devastating on a personal level for Ito
given how he has shown his value over the last few weeks and slowly recovered his form and fitness
Upamecano is facing several weeks out already
and Davies will not play again this season
Ito’s ability to provide cover in both positions had softened the blow of those injuries
this has turned into a crippling defensive crisis
Ahead of the Champions League tie with Inter Milan
Kompany now only has two available centre-backs
who is not as defensively secure as Ito and has a very different set of abilities
Sascha Boey could offer support in that role too
but he is much more comfortable on the right side and typically looks vulnerable on the left — as he did against Bayer Leverkusen in that disastrous game at the BayArena last season
Boey is likely to leave the club at the end of the season and is out of favour for a reason
nobody will shed a tear for Bayern domestically
but with a new injury seemingly appearing every week
their task in Europe is getting tougher and tougher
