Among these materials, CuO2 superconductors like Bi2212 stand out due to their high critical temperatures that surpass the Bardeen–Cooper–Schrieffer limit, a theoretical maximum temperature limit for superconductivity. However, ...

Artificial molecular machines, nanoscale machines consisting of a few molecules, offer the potential to transform fields involving catalysts, molecular electronics, medicines, and quantum materials. These machines operate by converting external stimuli, like electrical signals, into mechanical motion at the molecular level. Ferrocene, a special drum-shaped molecule composed of an iron (Fe) atom sandwiched between two five-membered carbon rings, is a promising foundational molecule for molecular machinery. Its discovery earned the Nobel Prize in Chemistry in 1973, and it has since ...

Plastic pollution is an ever-growing problem in today’s world, as most societies have become overly dependent on plastics for packaging, medical supplies, and general goods. Plastic litter accumulation in the ocean, either through deliberate dumping or by being transported from a river, poses significant environmental challenges. Additionally, this plastic eventually degrades into small fragments called microplastics, which then impact diverse marine and land ecosystems by working their way up the food chain and into most living organisms. Though their negative effects on cell health are still under study, many nations have taken a cautionary stance, ...

A new study led by investigators from Mass General Brigham has identified a unique brain network that links varied patterns of brain atrophy, or shrinkage, associated with schizophrenia. By combining neuroimaging data from multiple studies involving more than 8,000 participants, the research team found a specific connectivity pattern of atrophy that was present across different stages and symptoms of schizophrenia — and distinct from brain networks associated with other psychiatric disorders. The findings will help to guide a clinical trial that will start recruiting patients soon and will ...

Research has long shown that humans are susceptible to “social identity bias”—favoring their group, whether that be a political party, a religion, or an ethnicity, and disparaging “outgroups.” A new study by a team of scientists finds that AI systems are also prone to the same type of biases, revealing fundamental group prejudices that reach beyond those tied to gender, race, or religion.  “Artificial Intelligence systems like ChatGPT can develop ‘us versus them’ biases similar to humans—showing favoritism toward their perceived ‘ingroup’ while expressing ...

It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is was previously unknown. Now, writing in the journal Nature Communications, a team of researchers from Charité – Universitätsmedizin Berlin posits an explanation. According to the study, the slow waves make the neocortex, the location of long-term memory, especially receptive to information. The findings could help to optimize the treatment approaches that are intended to support memory formation from outside. How do permanent memories form? Experts believe that while we sleep, our brains replay the events of ...

Railways, the most climate-friendly mode of transport bar long-distance buses, are bound to play an important role in the fight for net zero. The total emissions of railway travel are currently 31 grams of CO2 equivalents (CO2e) per passenger kilometer, half the amount as for the most economical electrical vehicles. But the carbon emissions of railway traffic can be further reduced, shows a new study in Frontiers in Sustainability by authors in Finland. This is because typical construction materials such as steel and concrete are energetically costly to produce, transport, handle, and maintain. Even on the ...

Food poisoning is a common, yet unpleasant, illness caused by eating contaminated items. It is sometimes caused by Clostridium perfringens, a pathogen widely found in soil and the intestinal tracts of animals. The pathogen multiplies in environments with little oxygen, for example, curry stored in a pot. After ingestion of the pathogen, they form spores in the small intestinal tracts. The toxins produced during spore formation cause diarrhea and abdominal pain, but the underlying mechanism of spore formation has not been fully understood. Associate Professor Mayo Yasugi’s team at Osaka Metropolitan University’s ...
