Parkinson’s disease: Intense exercise may help to keep the disease at bay

Neuroscientists from the Faculty of Medicine of the Catholic University, Rome Campus, and the A. Gemelli IRCCS Polyclinic Foundation have found that intensive exercise could slow the course of Parkinson’s disease. The finding could pave the way for new non-drug approaches. The study, “Intensive exercise ameliorates motor and cognitive symptoms in experimental Parkinson’s disease by … Read more

Crosswords and chess may help more than socializing in avoiding dementia

Computer use, crosswords and games like chess are more strongly associated with older people avoiding dementia than knitting, painting or socializing, a Monash University study has found. Published in JAMA Network Open, the findings—some of the most robust on this topic to date—may help older individuals and aged care professionals plan more targeted approaches to … Read more

Deepfake videos prompt false memories of films in half of participants

In a new study, deepfake video clips of movie remakes that don’t actually exist prompted participants to falsely remember the films—but simple text descriptions of the fake movies prompted similar false memory rates. Gillian Murphy of University College Cork, Ireland, and Lero, the Science Foundation Ireland Research Centre for Software, and colleagues presented these findings … Read more

Research lays groundwork for future high-performance alternatives to silicon in microelectronics

Researchers in the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering at the Technion in Israel have demonstrated control over an emerging material, which they consider as a possible future alternative to silicon in microelectronics. This is a timely development, because scientists and engineers face challenges in continuing the transistor shrinking trend, an … Read more

New material could hold key to reducing energy consumption in computers and electronics

A University of Minnesota Twin Cities team has, for the first time, synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy. The researchers were also able to closely study the material, leading to some important findings about … Read more

Improving high-temperature stability of perovskite solar cells

Perovskite solar cells (PSCs) have gained attention for their high power-conversion efficiencies and low-cost solution processing. However, ensuring their stability at high temperatures has been a challenge, as the points of contact between their different layers (“interfaces”) are susceptible to degradation, leading to energy loss and decreased performance. In a new study, researchers have found … Read more

Titanium oxide material lets sunlight drive green hydrogen production

Clean energy plans, including the U.S. Infrastructure Investment Act’s “Clean Hydrogen Road Map,” are counting on hydrogen as a fuel of the future. But current hydrogen separation technology is still falling short of efficiency and sustainability goals. As part of ongoing efforts to develop materials that could enable alternative energy sources, researchers in Drexel University’s … Read more

Spiking neural network based on theory of mind helps multi-agent cooperation and competition

Theory of mind (ToM) refers to the ability to infer mental states of others, such as beliefs, intentions, and desires. It’s a kind of high-level social cognitive ability. Neural mechanisms underlying ToM have been uncovered gradually in recent years. These mechanisms provide insights for studying and exploring social interactions among multi-agent systems and human-computer interactions … Read more
