Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers explored an innovative strategy to turn hard carbon into an excellent negative electrode material. Using inorganic zinc-based compounds as a template during synthesis, they prepared nanostructured hard carbon, which exhibits excellent performance in both alternative batteries.       Read more ›

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a novel way, which could potentially provide clues to new laws in physics. A research team has developed a series of proposals designed to help conduct the experiment more effectively --... Read more ›

White faces generated by artificial intelligence (AI) now appear more real than human faces, according to new research. In the study, more people thought AI-generated white faces were human than the faces of real people. The same wasn't true for images of people of color.  Read more ›

Researchers have studied the effects of elevated O3 on five C3 crops (chickpea, rice, snap bean, soybean, wheat) and four C4 crops (sorghum, maize, Miscanthus × giganteus, switchgrass). Their findings indicate that C4 crops are much more tolerant of high O3 concentrations than C3 crops. Read more ›

Having healthy mitochondria, the organelles that produce energy in all our cells, usually portends a long healthy life whether in humans or in C. elegans, a tiny, short-lived nematode worm often used to study the aging process. Researchers have identified a new drug-like molecule that keeps mitochondria healthy via mitophagy, a process that removes and recycles damaged mitochondria in multicellular organisms. The compound, dubbed MIC, is a natural compound that... Read more ›

Researchers used chiral (twisted) magnets as their computational medium and found that, by applying an external magnetic field and changing temperature, the physical properties of these materials could be adapted to suit different machine-learning tasks. Read more ›

For years, researchers and clinicians have known that lupus, an autoimmune condition, occurs in women at a rate nine times higher than in men. Some of the factors that cause the disease's high prevalence in women have eluded discovery, but in a new study investigating the immune system processes in lupus and the X chromosome, researchers have uncovered answers about the disease's frequency in females.

New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest... Read more ›

People in many parts of the United States possess few chances for the robust community engagement that underpins healthy democracies, according to a new report that for the first time maps civic opportunity across the country. The heat map reveals patterns of inequality in civic opportunity tied to race, class, immigration status and education. Read more ›

There is a general understanding that pets have a positive impact on one's well-being. A new study found that although pet owners reported pets improving their lives, there was not a reliable association between pet ownership and well-being during the COVID-19 pandemic. Read more ›

With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'  Read more ›
