A new study by the University of Tokyo reveals that some of Japan's earliest inhabitants came from the Korean Peninsula. The team performed genomic analysis on skeletal remains from the Yayoi period. The genes showed remarkable similarities to Korean people, showing how ancient immigration and mixing gene pools influenced modern Japanese genetics.
Artificial intelligence chatbots (or language learning models – LLMs) can be useful additions to everyday life but can still cause some concern regarding privacy. Researchers from Nanyang Technological University and UC San Diego found a vulnerability that lets hackers use hidden prompts to steal personal info from chatbots. They tested it on two chatbots with an 80% success rate, highlighting a major AI security risk.
Yonsei University scientists discovered a new type of tiny crystal structure in a solid material, called electronic crystallites which were first predicted in 1934. This breakthrough could help solve long-standing puzzles in physics, like how to make better superconductors for energy production and technological innovation.
Our gut microbiome influences many things such as physical and mental health. This does not just apply to adults but children too says research by Kyoto University and Osaka University. When analyzing samples from children and comparing it with results from surveying the parents, the researchers found that kids with higher rates of pro-inflammatory gut bacteria showed more negative emotions and were less likely to take on new challenges.
The Earth is warming at an alarming rate, but this is not a smooth increase. Climate change is warming winters faster than summers, and research by Lanzhou University shows that this reduces soil microbes' ability to store carbon. These microbes store carbon to make body parts but the study showed that asymmetric warming cuts microbial growth by 58% and their carbon use efficiency by 81%.
