The summer of Ukrainian blouses and a history of protest dressing

Across Ukraine, from politicians to front-line soldiers, people are taking pride in their vyshyvanka. They are in a long line of people using clothing as a form of protest

On 19 May, Olena Zelenska, First Lady of Ukraine, wrote an Instagram post marking Vyshyvanka Day, the annual celebration of the country’s national dress. The event, which takes place on the third Thursday of May every year, is dedicated to preserving Ukraine’s traditional embroidered clothing. This year, amid the continued Russian invasion, the day took on a renewed significance.

“Someone pulls [their vyshyvanka] out, miraculously surviving, from a closet in a ruined house. Someone is looking for theirs in another country, where the war drove them…Someone will wear theirs living under occupation…and someone else will wear it for the first time, because it was the first time they felt such a need,” wrote Zelenska.

People across Ukraine, from seasoned vyshyvanka collectors and politicians, to front line soldiers and President Zelensky, wore their cottons and linens this year, embroidered with exquisite motifs that span bold, expressive flowers and intricate repeating patterns.

The vyshyvanka celebration even crossed borders as people from around the world showed their support. Kristina Korniiuk, 34, who fled to Cambridge from her home in Kyiv, went as far as creating a giant embroidered shirt out of a bedsheet to “show the world how beautiful we are”.

Support for Ukraine via the medium of clothes has spread beyond the vyshyvanka. Blue and yellow, the colours of the nation’s flag, became the palette of choice for Fashion Week attendees and designers who wanted to communicate solidarity with the people of Ukraine. Blazers, bodysuits, blanket wraps, and even stud-toe wellies were suddenly imbued with meaning.

Meanwhile, a photo of a woman wearing a blue headscarf and a yellow leather jacket on the Moscow underground went viral. “Sometimes the act of resistance doesn’t have to be loud or bold, it just has to be”, a Twitter post sharing the image read.

Blue and yellow was also the inspiration for the Support Ukraine Collection by Ukraine-founded digital fashion brand DRESSX. The collection was launched just two days after the invasion to raise money for the Ministry of Defence, fashion designers affected by the conflict, and charities.

The campaign raised 200,000 UAH (around £5,400) within the first 12 hours. Beyond facilitating essential fundraising, it provided the building blocks for a global display of support and resistance.

Some may argue that a dress won’t do much to end an invasion, and yes, this alone can’t achieve peace. But clothing as a vehicle for protest and identity is a long-established practice, whether it’s a single black glove worn on an Olympic podium in 1968 or a red, white, and blue striped cockade worn by a French revolutionary.

In September 2021, Dr Bahar Jalali, founder of the first gender studies program in Afghanistan, posted a photo of herself on Twitter wearing a traditional Afghan dress. It was a response to strict dress codes introduced by the Taliban, following the fall of Kabul in August 2021, which required women to wear all-black garments and to cover their hands, face, and feet.

From there, the hashtag #DoNotTouchMyClothes spread across social media as women shared their rich, colourful traditional clothes as both a celebration of their culture and a protest against the Taliban’s control over women.

“As with most things, everyone has a different way of understanding, so I think [fashion] is effective for some people because it helps them learn about a story or a movement,” says fashion and homeware designer Tihara Smith. “It won’t work for everyone but it’s important to have different touchpoints.”

Smith’s own work takes reference from the Windrush generation and the stories her grandparents told her of coming to the UK. Woven raffia bags and wall hangings embroidered with Caribbean wildlife and botanicals take their inspiration from traditional straw crafts, while slogans such as “Nuff Love” and “You Called, We Came” in vibrant shades of pink, green, and yellow reference album covers from calypso and reggae artists.

“I think it’s important to help carry the story. Future generations can see [the clothing] and really understand it without having to read anything. It gives you an idea of the message, the history, and the materials,” Smith says.

Irish fashion designer Róisín Pierce also looks to her heritage to inform her delicate yet sculptural, all-white designs. Her signature techniques including smocking, Irish crochet, lace, and needlework, were all taught in the Magdalene Laundries – sites where extensive abuse and exploitation of women took place – across Ireland. “It is extremely beautiful work borne from great tragedy. There is a generational history, and it’s important that these skills are not forgotten,” Pierce says.

“I love that people learn more about Irish history from my work, especially the topic of the Magdalene Laundries,” Pierce continues. “The connection between Irish women and craft – its oppressive and liberating roles in their lives – is fascinating.

“My designs are heavily guided by socio-political concepts and historical references but it’s important to me that it doesn’t look like something taken directly from the past.” Inspiration from Pierce’s own happy childhood memories – “starburst shine and beautiful light” – injects a sense of playfulness too.

Like Pierce, the women of the Herero Tribe in Namibia, also use clothing to explore the space between past and present, oppression and expression. The women of the tribe dress in the Victorian silhouettes of the German colonisers who took the lives of nearly 80 per cent of their population in the early 1900s.

The tribe reference the style of dress of these European missionaries but also subvert it with bold colours, patchwork, sumptuous clashing textiles, and cow horn-shaped headpieces which symbolise their respect for cattle. In adopting, and adapting, the garb of their colonisers they remember their ancestors while redirecting their own cultural identity. Now, the dresses represent a rite of passage for Herero women.

The stories that underpin blouses, dresses, and gloves are often complex and heavy, and there’s no sidestepping that. Clothing alone can’t end wars or undo tragedies, but it does make space for joy, expression, and identity. When there’s a story to be told or a statement to make, the immediacy and impact of wearing it – embodying it – is hard to beat.

Tear gas fired at Liverpool fans in Champions League final policing chaos

Associated PressMay 28, 2022, 

PARIS (AP) — Riot police fired tear gas and pepper spray at Liverpool supporters forced to endure lengthy waits to get into the Champions League final amid logistical chaos and an attempt by UEFA and French authorities to blame overcrowding at turnstiles on people trying to access the stadium with fake tickets on Saturday.

The start of the showpiece game of the European football season, which Liverpool lost 1-0 to Real Madrid, was delayed for 37 minutes and kicked off as security was still struggling with the flow of frustrated supporters into the Stade de France.

UEFA claimed there were thousands of ticketless fans trying to gain access to the 80,000-plus capacity French national stadium but it did not identity where they were from.

French Interior Minister Gérald Darmanin claimed stewards for assaulted by Britons who forced entry without tickets or with counterfeit tickets. French Sports Minster Amélie Oudéa-Castéra also overlooked any shortcomings by authorities by claiming thousands of English fans “complicated the work of stewards and police forces" and tweeting: “Violence has no place in the stadiums.”

Liverpool said it was “hugely disappointed” with the security issues experienced by its fans.


Angry Liverpool fans held in the lines were seen hanging onto railings and heard shouting: “Let us in. We’ve got tickets.”

There were many instances of fans breaking through security and attempting to get into the stadium. The Associated Press saw two fans — one was wearing Liverpool attire — wrestled to the ground by stewards and bundled out of the gates.

Three more fans were seen evading stewards and sprinting through the concourse and into the bottom level of the stadium. Other people, wearing no obvious club attire, climbed the fences instead as Liverpool fans shouted at them to get down.

The final kicked off despite fans still trying to get through ticket checks. Fresh rounds of tear gas were fired by riot police from inside the security perimeter at people outside the fences. Police and stewards were seen falling to the ground, impacted by the eye-irritating substances.

There was anger in the Liverpool squad after losing the final.

“Pretty much all of our families were affected, I think," Liverpool defender Andy Robertson said. "Obviously my tickets were through the club and somehow somebody told one of my mates that he’s got a fake ticket which I can assure you definitely wasn’t because it was obviously through me.

“So then obviously the French police decided to throw tear gas on fans and families. It’s not been well-organized.”

Merseyside Police, the force covering Liverpool, tweeted that the “behavior of the fans at the turnstiles was exemplary in shocking circumstances.”

Supporter Colm Lacey saw “children crying, people trapped” outside the entrances.

“People started jumping the queue, then they ripped the gate open and then there was a push,” Lacey said.

About 15 minutes before the scheduled kickoff of 9 p.m. local time, an announcement was made that there would be a delay, blaming the late arrival of fans to the stadium. It was greeted by jeers inside the stadium, given those fans had already endured long queues. The game eventually started at 9.37 p.m.

“We’ve been stood at this gate since 6:15,” Liverpool fan Angela Murphy told the AP through a fence. "I’ve got really bad asthma and I’ve been tear gassed twice. I’m really struggling.”

Asked what provoked the tear gassing, Murphy replied: “Nothing, we’re stood here. There was nothing. It’s just been horrendous. We have been well behaved.”

Police officers with batons and riot shields ran from gate to gate to prevent pockets of fans forcing their way into the stadium without showing tickets. One policeman collapsed to the ground and had to be helped by other officers. Officers used tear gas on Liverpool fans on repeated occasions.

One Liverpool fan kissed his ticket and looked to the sky after finally getting through security.

Liverpool supporter Joe Moorcroft complained about being treated like animals.

“It’s a disgrace. We’ve seen this before, it’s a risk to health,” he said. “We’ve seen this and it’s going to happen all again. I feel it now. They threw tear gas in the fans.”

UEFA said it was “sympathetic to those affected” and it announced an urgent review by French police and authorities along with the French Football Federation.

“In the lead-up to the game, the turnstiles at the Liverpool end became blocked by thousands of fans who purchased fake tickets which did not work in the turnstiles,” UEFA said in a statement.

“This created a buildup of fans trying to get in. As a result, the kickoff was delayed by 35 minutes to allow as many fans as possible with genuine tickets to gain access. As numbers outside the stadium continued to build up after kickoff, the police dispersed them with tear gas and forced them away from the stadium.”

Liverpool wants a formal investigation.

“We are hugely disappointed at the stadium entry issues and breakdown of the security perimeter that Liverpool fans faced,” the club said in a statement. “This is the greatest match in European football and supporters should not have to experience the scenes we have witnessed tonight.”

The scenes were reminiscent of the chaos outside Wembley Stadium before the European Championship final last year. That was largely due to England fans aggressively trying to get into their home stadium for the game that Italy won.
Zimbabwe’s court raises age of consent for sex to 18 years

HARARE, Zimbabwe — Zimbabwe’s Constitutional Court has ruled that the legal age of consent for sex should be raised to 18 from 16, a judgment welcomed by many in a country where rights groups say teen pregnancies are forcing hundreds of girls out of school.


In a ruling handed down by the country’s highest court this week, the court struck down as unconstitutional provisions in the Criminal Law that set the age of consent for sex at 16.

Following the court’s decision, the minister of justice and parliament have 12 months to “enact a law that protects all children from sexual exploitation in accordance with the provisions of the Constitution,” read the ruling.

The case was brought by two women who were married as children.

Many welcomed the ruling in hopes that criminalizing sex with underage girls could help slow cases of teen pregnancies and child marriages. Authorities and human rights groups say cases have spiked following the outbreak of COVID-19 that resulted in prolonged school closures and deepening poverty.

“It is vital that we protect children, especially girls. This ruling will not stop child abuse, but it will mitigate, it offers a deterrent,” Tendai Biti, a lawyer who argued the case, told The Associated Press on Thursday.

“This ruling guarantees protection of girls under 18. In the past we had old men taking advantage of girls. Pedophiles were getting away with abuse,” said Talent Jumo, director of Katswe Sistahood, a group that campaigns for girls’ rights. She described the ruling as “a landmark.”

The age of consent for sex has for long been controversial in this southern African country. Campaigners argued that the 16-year age for consent was too young and it allowed for the exploitation of young girls.

However, Justice Minister Ziyambi Ziyambi argued in parliament late last year that “most children are mature, beyond their age nowadays and are already sexually active.” He claimed that raising the age of consent to 18 “means children below the age of 18 having sexual intercourse will be criminalized” and have “unwanted criminal records.”

The Constitutional Court in 2016 outlawed marriage before the age of 18 following a challenge to provisions of the marriage law that allowed child marriages.

In the latest case, Biti argued on behalf of the women that it was unconstitutional that children could not be married until they attain 18 “yet the law allowed them to be abused from the age of 16.” Biti is also a leading official of the opposition party the Citizens Coalition for Change.

“Men were now having their cake and eating it too, so in some instances a man could say ‘I slept with you, I want to marry you but the law says I can’t marry you but I can have sex with you’.” Zimbabwe’s constitution defines a child as someone below the age of 18.

However, even supporters of the latest ruling urged caution, noting that more needs to be done to eradicate entrenched religious, traditional and cultural norms and as well as deepening poverty which all promote teen pregnancies and child marriages.

“Religious and other groups that had made this a norm are a major threat and need to be stopped. Secondly, children should be protected from the negative consequences of early sexual debut by providing access to sexual reproductive and health rights information and also provide for a ‘Romeo and Juliet’ clause in the law to guard against criminalizing adolescent sexual activity,” said Jumo, of Katswe Sistahood.


The “Romeo and Juliet clause” in legal terms often seeks to protect from criminal prosecution underage children who engage in consensual sexual activity with each other.

As the US supreme court creeps right, a broad view of the second amendment emerges

Trump’s presidency saw three new rightwing judges, each backed by the powerful gun lobby movement

Sun 29 May 2022 

As the world looks on in horror following mass killings in Buffalo, New York and Uvalde, Texas, the US supreme court is set to issue its first major ruling on gun rights in over a decade.

And with a conservative super majority now installed on the bench, most onlookers expect a substantial broadening of second amendment rights in the country despite the widespread revulsion at the latest shootings in a supermarket and a school.


Although such a decision may seem incongruous with the outpouring of grief and anger after the murder of 19 Texan elementary school students and two teachers at the hand of an 18 year-old assault rifle wielding gunman earlier this week, it would also be in keeping with the creeping rightwing extremism on America’s highest court.


Washington’s shame: how previous bids to tighten gun laws have failed

A far reaching legacy of Donald Trump’s four years as president, which saw the installation of three rightwing judges, each backed wholesale by the powerful gun lobby movement.

“Before the Trump appointees were on the supreme court, the court had multiple opportunities to take cases that could expand second amendment protections, but it repeatedly turned those efforts aside,” said Adam Winkler, a supreme court and gun policy specialist at UCLA law school. “Now we see that the supreme court is taking big gun cases and seems prepared to issue a very expansive ruling. This is directly attributable to the 2016 election.”

Before the court comes New York State Rifle & Pistol Association v Bruen, a case challenging a New York law limiting concealed handgun carry in public. The law, more than a century old, requires residents to obtain concealed carry licenses by demonstrating they face a “special or unique danger to life” requiring firearms possession in public.

Oral arguments were held in November 2021 with a ruling expected soon, and although observers expect a judgment striking the law down, just how expansive that ruling becomes is key to anticipating the seismic nature of the decision.

Around half a dozen states have similar concealed carry laws to New York that would likely be struck down by the ruling. But, said Jake Charles, a lecturer at the center for firearms law at Duke University, the argument behind the ruling itself could be critical to further expansion of gun ownership rights across the country.

“The court is going to make a decision about how lower courts should even consider the constitutionality of gun laws,” said Charles. “If it [the supreme court] adopts a test that says courts can only look to history, they can only look at the text of the constitution or to history to determine whether or not a gun law is constitutional … that is going to open up every other gun law that there is.”

It was 2008 when the supreme court last handed down a major second amendment ruling, in the District of Columbia vs Heller decision, which found it was constitutional for Americans to keep firearms at home for self-defense. But contained within that ruling, written by former justice Antonin Scalia, was wording that limited the scope of the judgment and, by extension, interpretation of the second amendment itself.

The decision noted gun ownership rights were “not unlimited” and does not translate to a “right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose”. The explicit wording has been used since by lower courts to uphold gun restrictions in the aftermath.


The supreme court ruling in the New York case is likely to pave the way for further decisions.

But the new rightwing extremism on the supreme court is now likely to threaten that legal status quo. And despite the NRA’s internal leadership crisis and ongoing legal jeopardy (at the hands of the New York attorney general) the pro-gun lobby is gearing up for a major victory after the installation of three NRA-backed justices on the nation’s highest court.

“In terms of constitutional law, the NRA has never been stronger,” said Winkler. “Those three justices on the supreme court are going to embrace the broad vision of the second amendment that the NRA has been promoting for the last half century.”

The ruling in Bruen is likely to pave the way for further decisions as other cases involving state gun restrictions make their way up to the legal ladder. Last year the NRA petitioned the supreme court to hear a case challenging a law in New Jersey that restricts firearms magazines to 10 rounds. While gun advocates in Hawaii have taken a case challenging the state’s restrictive open-carry laws to the supreme court as well.

It is, said Charles, extremely unlikely the events in Buffalo or Uvalde will have any bearing on the Bruen decision itself. “If it did have an effect, my guess would be that it affects when they’re going to issue the decision and less what the decision is.”

But, said Winkler, if the court rules the way it is expected, the decision will become another indication of the opinions of a minority of Americans determining the national legal landscape.

“The supreme court has historically been a voice for the protection of minorities. However, the court today is not protecting racial or political minorities. The court is protecting a very conservative agenda, a conservative constitutional vision that is really not shared by the public at large.

“I think the court will run some risks in terms of its public legitimacy if it insists on a series of rulings that don’t stay within the broad parameters of widely shared public opinion.”



Using ketamine to find an undiscovered pathway

Finding a new target for future antidepressant development

Ketamine, the unintentional antidepressant

For the 280 million people suffering from depression globally, relief cannot come fast enough. Monoaminergic antidepressants, including selective serotonin reuptake inhibitors (SSRIs) take weeks to months to take effect and do not work for more than one in three patients. For patients diagnosed with treatment-resistant depression, or in immediate crisis, access to safe, effective, rapid-acting antidepressants can improve lives and decrease suicide.

One current possibility being investigated is ketamine, which can improve depression, even in treatment-resistant patients. Ketamine is an anesthetic used for over 50 years, but it has serious side-effects, including dependence, hallucinations, and delusions. So, while preclinical studies have shown that a single dose of ketamine can have beneficial long-term effects on mental health and is only used to treat depression as a last resort. There are good reasons to be cautious; in addition to the side-effects, the way ketamine alters brain chemistry is not fully understood. If the biological mechanisms in the brain that ketamine influences are discovered, new drugs could be developed to target the beneficial antidepressant effect specifically.

The study led by Professor Kondo demonstrated ketamine treatment led to an increase in insulin-like growth factor 1 (IGF-1), a known antidepressant brain molecule. However, they did not know if this was linked to previously discovered ketamine related antidepressant molecules like brain-derived neutrophic factor (BDNF). They confirmed IGF-1 produced an antidepressant effect then demonstrated that they could switch it off by blocking it with an IGF-1 neutralizing antibody.

After demonstrating they could switch off IGF-1, the researchers followed up with a separate experiment. Previous studies have shown that ketamine increases BDNF, a protein that promotes nerve growth, so the researchers wanted to check if IGF-1 and BDNF were working together or separately. They tested whether IGF-1 and BDNF neutralizing antibodies blocked the other proteins antidepressant effect, they did not, leading the researchers to conclude that IGF-1 and BDNF work through their own independent pathways.

This discovery indicates that ketamine uses a previously unknown pathway that produces an antidepressant effect. The researchers hypothesized that the single dose of ketamine increases the level of IGF-1 in the brain, persistently changing prefrontal cortex nerves and causing them to increase their number of stable connections. The link between ketamine and IGF-1 presents a brand-new direction for future studies investigating antidepressants that target IGF-1 directly.

The paper, “IGF-1 release in the medial prefrontal cortex mediates the rapid and sustained antidepressant-like actions of ketamine,” was printed in Translational Psychiatry (DOI 10.1038/s41398-022-01943-9) on May 17, 2022.

Startups near state lines gravitate toward side with lower property tax

AMES, IA – Researchers at Iowa State University found significantly different state tax rates affect where new businesses set up shop near state lines. Their study published in the journal Small Business Economics shows the fourth greatest distortion in the U.S. is between Iowa and its northwest neighbor.

"The probability of starting up on one side of the border versus the other due to tax rates is 7.5% higher in South Dakota than Iowa, but it may not be for the reasons people think. Namely, property taxes seem to matter more than other types of taxes and providing certain incentives for some businesses in Iowa may hurt others,” said University Professor of Economics Peter Orazem who led the study.

Orazem explained he and his team focused on state borders because this approach helps control for unobservable local factors that would influence new businesses on both sides of the border, such as an atypically strong local economy, better local access to labor or venture capital, or an unusually supportive local business community.

To collect their data, the researchers looked at the individual and combined effects of four types of state taxes (i.e., property, sales, personal income, corporate income) and pulled information on new businesses less than a year old between 1999 and 2015 from the Statistics of U.S. Businesses under the U.S. Census Bureau.

“The reason we were particularly interested in business startups is that they may consider multiple locations to set up. They will be more sensitive to different tax rates compared to a well-established firm that would have to move all of its equipment and employees or find new workers if it jumped state lines,” said Orazem.

The researchers found a state with a one-point higher tax rate in each of the four types of taxes will have a “small but statistically significant” 3.2% lower probability of attracting a startup than its neighboring state. The greatest distortion in startups due to tax rates in the U.S. is Wyoming's 8.6% advantage over Idaho. Wyoming’s state revenue is largely subsidized by taxes and royalties from fossil fuel production in the state, which eases the pressure to tax other types of businesses.

Orazem and his team emphasized the probability of businesses starting up on one side of the border or the other drops off when two neighboring states have similar tax structures. For example, Rhode Island has the highest tax rate in the U.S., but its neighbor, Connecticut, has the third highest tax rate, essentially erasing what could otherwise be a disadvantage.

The study also found property taxes have the greatest adverse effect on the rate of new businesses. Orazem explained that’s because new businesses may pay property taxes even if they are not generating any revenue.










Gaining a competitive edge

As director of the Program for the Study of Midwest Markets and Entrepreneurship at ISU, Orazem said he and his colleagues are always trying to figure out what incentivizes and prevents businesses from setting up in Iowa and the region.

"Tax policies are one of the reasons why people have specified South Dakota as being a relatively faster growing state in the Midwest. So, even though the study isn’t focused on South Dakota, we were curious if we could see a difference, which we did.”

But Orazem emphasized many of the strategies implemented in Iowa to try to stay competitive with South Dakota are not necessarily the most efficient.

“What’s bizarre about Iowa is we tend to have high marginal tax rates, but then we give tax breaks to some businesses and not to others. For example, we have around 450 special exemptions for the sales tax,” said Orazem. "Maybe we should stop giving special deals in general but lower tax rates where they really matter, like property tax rather than income tax.”

Orazem said he hopes the study’s findings will open the discussion but recognizes state tax reform is challenging.

Why are male mice afraid of bananas?

Researchers from McGill University have identified a form of chemical signaling in mice to defend their offspring

Peer-Reviewed Publication

MCGILL UNIVERSITY

Researchers from McGill University have identified a form of chemical signaling in mice to defend their offspring. The researchers found that proximity to pregnant and lactating female mice increased stress hormones in males and even decreased their sensitivity to pain. “The findings have important implications for improving the reliability and reproducibility of experiments involving mice. This is yet another example of a previously unknown factor in the lab environment that can affect the results of scientific studies,” says Jeffrey Mogil, a Professor in the Department of Psychology at McGill University and E. P. Taylor Chair in Pain Studies.

According to co-author Sarah Rosen, “what is likely happening is that female mice are signaling to males who might be considering attacking their babies that they will defend them vigorously. It’s the threat of the possible upcoming fight that causes the stress.”

“Mice have richer communication with one another than we think; it’s just that a lot of it’s through smell,” says Mogil. The researchers started looking for the olfactory chemical responsible. Several odorants were identified, but one, n-pentyl acetate, which is released in the urine of pregnant and lactating female mice, was especially effective at producing stress in male mice. “Curiously, n-pentyl acetate is also responsible for the unique smell of bananas. After a quick trip to the supermarket for some banana oil, we were able to confirm that the smell of banana extract stressed the male mice just as much as the pregnant females,” says co-author Lucas Lima.     

The finding represents a breakthrough in the science of mammalian social signaling. “There are a number of examples of male-to-female olfactory signaling in rodents, but far fewer examples of female-to-male signaling, especially outside of the realm of sexual behavior,” says Mogil.

"Olfactory exposure to late-pregnant and lactating mice causes stress-induced analgesia in male mice" by Sarah Rosen et al. was published in Science Advances.

Using origami and kirigami to inspire reconfigurable yet structural materials

McGill University researchers developed metamaterials that can flat-fold and lock into positions that remain stiff

Origami, the Japanese art of folding paper into decorative shapes and figures, has long served as inspiration for industrial design. The concept of folding has been used to build reconfigurable structures, which change their function by changing their shape. These structures are promising for applications such as nanorobots for drug delivery, foldable solar panels for aerospace, and morphable cladding and shading for architecture. However, most of these designs cannot bear heavy loads. Those that can are only able to do so in a certain direction, collapsing along the direction in which they fold. This limits their use as structural materials.

A study by a group of McGill University researchers may provide a solution to this limitation. By merging concepts from origami and kirigami, the practice of folding and cutting paper, researchers developed a class of cellular metamaterials that can flat-fold and lock into several positions that remain stiff across multiple directions.

“Their load-bearing capacity, flat-foldability, and reprogrammability can be harnessed for deployable structures including certain submarines, reconfigurable robots, and low-volume packaging,” said Damiano Pasini, Professor in the Department of Mechanical Engineering and lead researcher on the study. "Our metamaterials remain stiff in several directions, yet rigidly flat-foldable metamaterials, attributes unprecedented in the current literature.”

Center for BrainHealth and Warfighter Fitness

Business Announcement

CENTER FOR BRAINHEALTH

The National Guard Bureau has taken a bold step toward securing and enhancing Warfighter brain health, and ensuring cognitive combat readiness with the launch of a new initiative to measure, track and improve cognitive performance and psychological well-being. The Warfighter Brain Fitness program is a research protocol with almost 1,000 participants across the United States. In partnership with Applied Research Associates, Inc., the Center for BrainHealth® at The University of Texas at Dallas, Posit Science, and Cortical Metrics, the Warfighter Brain Fitness program will collect data to optimize the online delivery of scientifically validated cognitive training approaches to reserve and active-duty populations.The Warfighter Brain Fitness program leverages the BrainHealth dashboard and BrainHealth Index (BHI), both developed at the Center for BrainHealth for the purpose of conducting a similar large-scale study (The BrainHealth Project) in civilian populations. The BHI is a multi-dimensional measure of brain health and its upward potential. It is a composite metric derived from a series of best-in-class assessments that explore multiple aspects of an individual’s cognitive capacity, as well as their sense of well-being, quality of social interactions and complexity of daily routines. The result is a personalized, holistic score that becomes an individual’s baseline against which gains can be measured and analyzed.Participants in the Warfighter Brain Fitness program will also have access to the Brain Gauge, a small device similar to a computer mouse, that delivers vibrations to a user’s fingertips. The user answers simple questions about the vibrations, like “Which finger felt a vibration first?” and “Which finger felt the vibration for longer?” Over time, the vibrations become increasingly similar, making it increasingly difficult to answer these questions. Data on a user’s performance is analyzed using a machine learning model to provide a quantitative neurofunctional measure of brain health that has been validated in numerous DoD-funded studies.Most importantly, participants in Warfighter Brain Fitness will engage in two complementary approaches to brain training: SMART+ and BrainHQ. A proprietary protocol developed and tested by BrainHealth researchers over the past two decades, SMART+ teaches top-down cognitive strategies on how to process information more deeply and accurately, with an emphasis on improving complex cognitive functions, such as reasoning, problem-solving, decision-making and innovation. BrainHQ is a set of computer games that provide increasingly difficult challenges to bottom-up cognitive processes such as spatial processing speed and inhibition. BrainHQ increases the speed and accuracy with which the brain processes information. Both SMART+ and BrainHQ are extensively validated but have never been used together as they will be in Warfighter Brain Fitness.

“The National Guard has really taken a leadership role in the Department of Defense in terms of prioritizing brain health, both as a means of increasing combat readiness and as a way of reducing the risk of significant psychological health issues. Through this effort, we expect to demonstrate the feasibility of improving brain health through cognitive training, and we will use the data we collect to refine how we deliver this training to active and reserve duty military personnel.” – Dr. Leanne Young, Principal Investigator, ARA

Jennifer Zientz, deputy director of programs at Center for BrainHealth, added, “We are proud to partner with Applied Research Associates, the National Guard and Special Operators in this unique, science-driven program to tackle brain health with focus and urgency. Better brain health enables people of every age and occupation to thrive in a constantly changing world, and our warriors and protectors deserve the most leading-edge tools and techniques to drive peak brain performance.”About Center for BrainHealthThe Center for BrainHealth®, part of The University of Texas at Dallas, is a translational research institute committed to enhancing, preserving and restoring brain health across the lifespan.
