A large-scale, multi-institutional study designed to examine human behavior has shown that communication helps groups of strangers to focus on resolving common problems, and provides new and surprising insights into what goes on when negotiation talks fail or succeed. The findings have implications for how to confront global, collective-action issues such as climate change mitigation.

Challenging global issues are frequently accompanied by shared associated risks, and without a concerted effort, resolution is hard to achieve. Climate change talks often stall when nations start accusing one another of contributing too little. When such a stalemate arises, it becomes unclear how to move forward or how to make involved parties adhere to agreed-upon terms.

Waiting for others to resolve common problems is recognized in behavioral studies as a form of free riding, which can ultimately hinder the group’s chances of achieving a given goal. To examine what causes free riding, and how to stave it off, a team of international researchers coordinated by Marko Jusup from Tokyo Institute of Technology (Tokyo Tech) in Japan and Zhen Wang from Northwestern Polytechnical University in China conducted a so-called social-dilemma experiment through which the team could investigate whether communication might help improve cooperativeness among strangers tasked with avoiding a shared risk.

The team organized a game experiment played by groups of three, seven, or 11 individuals. A total of 351 students from southern China, 126 students from northern China, and 112 students from 33 different nations participated in the game.

In each round of the game, players had to decide whether to invest their capital toward mitigating the shared risk, or to forgo investing and take more of the capital home, provided that the risk had not materialized. Thus, the dilemma was whether to invest one’s own capital or wait for others to act.

Investment options consisted of zero, two, or four units of capital — if everybody invested two units in every round of the game, the risk would be mitigated with certainty. Groups of, for example, seven individuals playing ten rounds of the game had to reach a target of 140 units to mitigate the risk. The initial capital consisted of 40 units per player. To make informed decisions, players could see their group’s current-round investment, as well as the remaining amount towards the target. Failure to reach the target entailed losing any capital saved during the game, and going home empty-handed, with 50% probability.

Approximately half of the players engaged in games in which no communication was possible. These players relied on their own devices to decide whether to invest or not. The other half played the same games, but with limited communication. This communication took place between game rounds, in the form of five yes/no questions designed to gauge sentiment and outlook harbored by player groups.

Across all group sizes, the study found that communication increased the likelihood of reaching the target by almost two-fold. The results thus confirmed a natural expectation that communication promotes cooperativeness, but the story does not end with a more cooperative environment created simply by persuading free riders to invest.

Intriguingly, the researchers found that players who communicate are more persistent in pursuing the investment target and refuse to give up even in the face of substantial current deficits. Genuine free riders appear to pay little attention to communication. It is players who already possess prosocial tendencies that, when communicating, better endure setbacks, and thus fight off inaction as the failure looms.

“Without communication, prosocial players shut down upon seeing nothing but a widening deficit. With communication, however, these same players stay hopeful thanks to cooperation-reinforcing signals from others,” write the researchers in their study published in the journal Proceedings of the National Academy of Sciences.

The study identified two prosocial behavioral types, namely cooperators and altruists. While altruists contribute almost unconditionally, cooperators are rather more astute, weighing carefully when and how much to contribute. Too much caution, however, often leads to near-misses of the investment target, meaning that even if just a few individuals fail to give their best at crucial times, the whole effort may be in vain. This is reflected in the fact that larger groups of communicating players often come close to mitigating the risk, but ultimately fail by a narrow margin. The overall lower success of larger groups points to additional challenges in coordinating an increasing number of individuals and highlights the insidious nature of collective-risk social dilemmas.

What, then, can be done to curb free riding and improve the situation for complex issues such as climate change talks? “The key is to leverage pre-existing goodwill, especially when an otherwise contributing side starts to doubt success,” says Jusup. “Persuading those who a priori have no intention to contribute is unlikely to amount to much,” adds Wang. Both researchers conclude that although experimental games can help uncover the mechanisms underlying mitigation efforts, caution needs to be heeded in extrapolating the study’s findings beyond experimental conditions.

Redefining aesthetics: From anti-aging to healthy aging

Growing attention is now being given to healthy aging, understanding how the entire face changes over time, preserving facial harmony, and helping people continue to look like themselves.

For decades, “anti-aging” has defined the beauty and aesthetics conversation, promising to erase wrinkles and reverse the signs of time. Today, that conversation is shifting.

Aging is no longer just about looking younger. Growing attention is now being given to healthy aging, understanding how the entire face changes over time, preserving facial harmony, and helping people continue to look like themselves.

A review published in Facial Plastic Surgery, The Anatomy of the Aging Face: A Review, describes aging as changes across bone, ligaments, muscles, fat, and skin. Another review in Aesthetic Surgery Journal, The Facial Aging Process From the “Inside Out”, explains how changes beneath the surface eventually become visible on top.

Studies in Plastic and Reconstructive Surgery show facial fat is organized into distinct anatomical compartments that can lose volume and shift position over time, altering facial shape and balance.

For multi-awarded aesthetic physician Dr. James Co, founder of Cosma Institute and Architect of Aesthetic Confidence, these findings are the reason aesthetic care must start with understanding, not just treating.

“Aging is not a disease we need to cure,” Co said. “It is a biological process. As physicians, our role is to understand what is changing beneath the surface, how those changes differ from person to person, and whether intervention is appropriate in the first place.”

“When you only look at the wrinkle, you are looking at the surface of a much bigger anatomical process,” he added. “The face ages as a system. Good assessment means understanding what is happening underneath before deciding what should be done on the surface.”

Part of that understanding is recognizing that no two faces age the same way. Two people can be the same age and experience aging very differently. Genetics, skeletal structure, fat distribution, skin characteristics, sun exposure, lifestyle, and environmental factors all influence how aging presents.

“Two patients can be the same age and come to me with completely different anatomy, lifestyles, concerns, and goals,” Co said. “Why would we expect their treatment plans to look exactly the same?”

This is where healthy aging broadens the conversation — from fixing isolated signs to looking at the face as a whole and listening to what the individual actually wants.

“Someone can want to look refreshed without wanting to look 20 years younger,” Co said. “Those are completely different goals.”

Rather than trying to freeze one version of the face forever, healthy aging acknowledges that the face will continue to change. As different structures change at different rates, the relationship between features evolves. Facial harmony is therefore not fixed.

“You cannot freeze one version of your face forever,” Co said. “But you can understand how the face is changing and make decisions that respect its natural proportions and your identity.”

In the age of social media, where aesthetic treatments are highly visible, Co cautions against self-diagnosis.

“Patients should not have to diagnose themselves from social media,” he said. “You might recognize a concern, but deciding why it is happening and what should be done about it requires proper assessment.”

The shift is also about how people feel, not just how they look. A 2022 review on minimally invasive facial aesthetic procedures found studies are increasingly looking beyond physical changes to include satisfaction with appearance and aspects of psychological and social well-being, while noting that evidence still needs careful interpretation.

For Co, this reinforces that success is not always about looking dramatically younger.

“We need to ask whether the result makes sense for the patient, whether expectations were met, and whether we preserved the things that make that person recognizable,” he said. “I would rather someone tell my patient, ‘You look well,’ than immediately ask, ‘What did you have done?'”

At Cosma Institute, Co applies this consultation-led philosophy through individualized assessment, facial harmony, medical judgment, and patient education. Having trained aesthetic practitioners across Southeast Asia and Europe, he advocates for natural-looking outcomes that respect the characteristics already present in each face — an approach that recently earned him two awards at the Merz Aesthetics Tala Awards.

For Co, the evolution of aesthetic medicine is not about having more tools, but knowing when to use them — and when not to.

“Aging cannot be stopped, and I don’t think that should be the promise,” he said. “What we can do is understand it better. We can look at the science, understand the anatomy, listen to the patient, and make decisions that allow them to age while still looking recognizably like themselves.”

For Co, healthy aging begins not with fighting age, but with understanding it.

The look and feel of your neighborhood may affect your sleep

Those living in neighborhoods rated as having a stronger sense of safety tended to sleep longer, and that this rating appeared to be shaped by the streetscape.

Published

Your neighborhood’s “streetscape”—the physical environment of your street—is something that you have probably never consciously thought about, despite seeing it every day. But what if the streetscape was affecting you on a subconscious level and disrupting your sleep? 

This intriguing question is posed by the findings of a study led by Professor Daisuke Matsushita of the Graduate School of Human Life and Ecology at Osaka Metropolitan University. The research team used AI to analyze more than 200,000 Google Street View images to identify visual neighborhood characteristics. They then linked these characteristics to the self-reported sleep of 1,089 working adults living on the lower floors of apartments in Tokyo, who were most likely to be affected by the streetscape.  

They found that those living in neighborhoods rated as having a stronger sense of safety tended to sleep longer, and that this rating appeared to be shaped by the streetscape. Generally, people slept longer in areas with lots of greenery, such as leafy trees, on the street. Similarly, high “enclosure”—meaning many tall vertical buildings and few wide-open spaces—was also associated with longer sleep and fewer insomnia symptoms. 

However, the study also made a surprising finding. The researchers found that highly walkable streetscapes, such as those with more sidewalks and traffic signs, were associated with a lowered sense of safety and shortened sleep duration.  

This suggests that walkability does not always represent a reassuring environment. Instead, a possible explanation is that streets with extensive pedestrian infrastructure are often busier, more crowded, and used by more strangers, which may be perceived as less safe or less relaxing than quieter residential streets.  

“This study demonstrates the potential for evaluating streetscape characteristics across large geographic areas in a cost-effective manner,” Dr. Matsushita said. “Based on the technique used in this study, cities could potentially measure perceived safety, beauty, liveliness, and enclosure as well as pollution and noise.”  

“We hope that opening up this new perspective creates further possibilities for designing healthier neighborhoods,” he concludes.  

The findings were published in Building and Environment.

Workout or nap? Either can help your sleepless brain, study finds

People who either completed 20 minutes of moderate-to-vigorous exercise or took a 90-minute nap performed about 22 per cent better on memory tests after 30 hours without sleep than those who did neither.

A short workout or a nap can help protect memory after a sleepless night, a McGill University-led study has found.

Researchers found people who either completed 20 minutes of moderate-to-vigorous exercise or took a 90-minute nap performed about 22 per cent better on memory tests after 30 hours without sleep than those who did neither. The findings, published in Proceedings of the National Academy of Sciences (PNAS), point to practical ways to counter the effects of sleep deprivation.

“Sleep loss affects nearly every aspect of how we think and function, but many people can’t simply stop what they’re doing and get more sleep,” said senior author Marc Roig, Professor in McGill’s School of Physical and Occupational Therapy. “Our findings show that even a brief bout of exercise may help preserve one of our most important cognitive abilities.”

The study involved 54 healthy young adults who stayed awake for 30 consecutive hours under lab supervision. Participants were then assigned to one of three groups: a 20-minute cycling session, a 90-minute nap or a control condition. Three days later, researchers tested their memory for images they had viewed immediately after the intervention. Those who exercised or napped remembered significantly more images than participants who did neither.

Same result, different pathways

While the memory benefits were nearly identical, brain recordings revealed that exercise and napping helped in different ways.

Napping appeared to help the brain recharge, making it easier to take in and remember new information. Exercise, by contrast, helped the brain use its remaining resources more efficiently, without making participants feel more tired.

The findings could eventually inform fatigue-management strategies in workplaces where sleep loss is common and mistakes can have serious consequences, such as health care, transportation and emergency response.

“A nap isn’t always possible in the middle of a shift,” said first author Madhura Lotlikar, a doctoral candidate in McGill’s Department of Neurology and Neurosurgery. “Exercise is accessible, inexpensive and easy to implement. That makes it a promising tool to help people stay cognitively sharp when sleep is limited.”

The researchers emphasize that exercise cannot replace sleep, but it may help people function better when getting enough rest isn’t possible.

About the study

“Protecting episodic memory after sleep loss: Similar benefits of exercise and naps via distinct neural contributions” by Madhura Lotlikar and Marc Roig et al., was published in Proceedings of the National Academy of Sciences of the United States of America.
