Psychology Today reports: In a study conducted in Milan, Italy, and published in November 2025, the sight of a person dressed as Batman led to a nearly doubled rate of people giving up their seat to a pregnant woman. Over the course of 138 subway rides, researchers found that people who saw "Batman" standing near the pregnant woman were far more altruistic than those who did not. Researchers are calling this the "Batman effect," suggesting a form of "involuntary" mindfulness may be at play. Noticing these subtle social cues appears to shift people's typical, automatic reactions. Most interestingly, 44 percent of the people questioned reported they did not even consciously register Batman's presence... The superhero costume serves as a visual nudge, pulling us out of our default, self-focused mode and into a more generous, attentive state. More from Futurism: Batman showing up is just one — albeit striking — way of promoting what's called "prosocial behavior," or the act of helping others around you, via introducing an unexpected event, the researchers write. "Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality," said study lead author Francesco Pagnini, a professor of clinical psychology at the Università Cattolica in Milan, in a statement about the work. "This may create a context in which individuals become more attuned to social cues." Thanks to Black Parrot (Slashdot reader #19,622) for sharing the article.

Twenty years after surgeons in France performed the world's first face transplant, the experimental field that procedure launched is now confronting a troubling record of patient deaths, buried negative data and a healthcare system that leaves recipients financially devastated and medically vulnerable. About 50 face transplants have been performed globally since Isabelle Dinoire received her partial face graft at University Hospital CHU Amiens-Picardie in November 2005. A 2024 JAMA Surgery study reported five-year graft survival of 85% and 10-year survival of 74%, concluding that the procedure is "an effective reconstructive option for patients with severe facial defects." The study did not track psychological wellbeing, financial outcomes, employment status or quality of life. Roughly 20% of face transplant patients have died from rejection, kidney failure, or heart failure. The anti-rejection medications that keep transplanted faces alive can destroy kidneys and weaken immune systems to the point where routine infections become life-threatening. In the United States, the Department of Defense has funded most operations, treating them as a frontier for wounded veterans, because private insurers refuse to cover the costs. Patients who survive the surgery often find themselves unable to afford medications, transportation to follow-up appointments or basic caregiving. The field's long-term grants cover surgical innovation but not the lifelong needs of the people who receive these transplants.

Je connaissais déjà l'aérogel de silice (on trouve plein de vidéos sur internet), mais c'est un matériaux fragile et friable.
L'aérogel de graphène semble beaucoup plus solide.
