Women born prematurely are at greater risk of committing suicide
2024-12-12
Not only are they the smallest among us, premature children also face health and life challenges that make them the most vulnerable. Generally speaking, they have a slightly higher risk of mortality due to illness. It is now apparent that they also have a higher risk of unexpected death from so-called external causes: road traffic accidents, substance abuse and suicide.
This has been revealed in a major Nordic study led by Professor Kari Risnes from the Faculty of Medicine and Health Sciences at the Norwegian University of Science and Technology (NTNU). The researchers have analyzed birth data and causes of death for nearly 37,000 individuals aged between 15 ...

Researchers reveal key factors behind Japan’s plastic waste removal rates in rivers
2024-12-12
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, ...

“Us” vs. “them” biases plague AI, too
2024-12-12
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 ...
Why deep sleep is helpful for memory
2024-12-12
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 ...
Sleepers made from recycled plastic could make railways even more eco-friendly
2024-12-12
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 ...
Ugh, my stomach: Identifying amino acids that prevent sporulation in food poisoning
2024-12-12
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 ...
