People with temporal lobe epilepsy in particular often wander around aimlessly and unconsciously after a seizure. Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Neurodegenerative Diseases (DZNE) have identified a neurobiological mechanism that could be responsible for this so-called post-ictal wandering and potentially other postictal symptoms. According to their hypothesis, epileptic seizures are not directly responsible for post-ictal symptoms, but rather seizure-associated depolarization waves, also known as spreading depolarization (SD). The results ...

Musical people find it easier to focus their attention on the right sounds in noisy environments. This is shown in a new study from Karolinska Institutet published in the journal Science Advances. The results suggest that music training can be used to sharpen attention and cognition. Being able to focus on a conversation in a room full of noise is a complex task for the brain. In a new study, researchers have investigated how music training affects the brain's ability to focus attention on specific sounds. The ...

Hydride ion (H⁻), with their low mass and high redox potential, are considered promising charge carriers for next-generation electrochemical devices. However, the lack of efficient electrolyte with fast hydride ion conductivity, thermal stability, and electrode compatibility has hindered their practical applications. In a study published in Nature, Prof. CHEN Ping’s group from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) developed a novel core–shell hydride ion electrolyte, and constructed the first rechargeable hydride ion ...

CAMBRIDGE, MA -- A genome-editing technique known as prime editing holds potential for treating many diseases by transforming faulty genes into functional ones. However, the process carries a small chance of inserting errors that could be harmful. MIT researchers have now found a way to dramatically lower the error rate of prime editing, using modified versions of the proteins involved in the process. This advance could make it easier to develop gene therapy treatments for a variety of diseases, the researchers say. “This ...

A “teenaged” pachycephalosaur from Mongolia’s Gobi Desert may provide answers to lingering questions around the dinosaur group, according to new research published today in the journal Nature. The fossil represents a new species of pachycephalosaur and is both the oldest and most complete skeleton of this dinosaur group found to date. “Pachycephalosaurs are iconic dinosaurs, but they’re also rare and mysterious,” says Lindsay Zanno, associate research professor at North Carolina State University, head of paleontology at the North Carolina Museum of Natural Sciences and corresponding ...

Could cocoa extract supplements rich in cocoa flavanols reduce inflammation and, in turn, prevent age-related chronic diseases? In a new study from the COcoa Supplement and Multivitamin Outcomes Study (COSMOS), investigators from Mass General Brigham and their colleagues looked at changes in five age-related markers of inflammation among participants who received daily cocoa supplements over several years. They found that hsCRP—an inflammatory marker that can signal increased risk of cardiovascular disease—decreased in participants taking the cocoa extract supplement, suggesting its anti-inflammatory potential may ...

When do people behave badly? Extensive research in behavioral science has shown that people are more likely to act dishonestly when they can distance themselves from the consequences. It's easier to bend or break the rules when no one is watching—or when someone else carries out the act. A new paper from an international team of researchers at the Max Planck Institute for Human Development, the University of Duisburg-Essen, and the Toulouse School of Economics shows that these moral brakes weaken even further when people delegate tasks to AI. Across 13 studies involving more than ...

Research supported by the National Institutes of Health (NIH) shows that repeated head impacts from contact sports can cause early and lasting changes in the brains of young- to middle-aged athletes.

Because lithium is relatively scarce and sodium is abundant in Earth’s crust, sodium-ion batteries are being investigated as viable cost-effective alternatives to the widely used lithium-ion batteries. In these batteries, the choice of cathode material primarily influences battery capacity and stability. Layered sodium manganese oxides (Na2/3MnO2) have attracted significant attention in recent years as cathode materials for high-capacity sodium-ion batteries without using any rare-earth metals. However, while these materials ...

Modern lifestyles and dietary changes have significantly increased the consumption of high-fat foods, contributing to a steep rise in the prevalence of obesity, diabetes, and metabolic disorders. Furthermore, a high-fat diet (HFD) is linked to cognitive impairments and neurodegeneration and has been shown to worsen the pathology of Alzheimer’s disease—a progressive neurodegenerative condition—in mouse models. Yet, the underlying mechanisms remain largely elusive. Autophagy, a crucial cellular recycling process, helps maintain neuronal health. Recent studies have shown that impaired autophagy contributes to neurodegeneration and cognitive decline. But is autophagy linked ...

Tulane University researchers have developed an enhanced CRISPR-based tuberculosis test that works with a simple tongue swab, a potential breakthrough that could allow easier, community-based screenings for the world’s deadliest infectious disease. Current TB tests rely on sputum, mucus collected from the lungs and lower respiratory system. While rich in TB bacteria required for testing, collecting sputum is difficult, making it inefficient for large-scale community testing. Sputum testing is also unfeasible in about 25% of symptomatic cases and nearly 90% of asymptomatic cases, a gap which contributes to an estimated 4 million tuberculosis cases going undiagnosed ...
