Humans have wiped out around 1,400 bird species — twice as many as previously thought — with major implications for the ongoing biodiversity crisis, a new study has found. The estimated extinctions would mean almost 12 per cent of bird species have died out over modern human history, since the Late Pleistocene around 130,000 years …

A team of researchers analyzed GPT-4’s performance in four clinical decision support scenarios: generating clinical vignettes, diagnostic reasoning, clinical plan generation and subjective patient assessments. When prompted to generate clinical vignettes for medical education, GPT-4 failed to model the demographic diversity of medical conditions, exaggerating known demographic prevalence differences in 89% of diseases. When evaluating …

During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material’s structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data. During X-ray diffraction experiments, bright lasers …

In Finland, there is a clear increase in the number of sick days taken due to depression, anxiety and sleep disorders in October and November, whereas the number of absences is lower than expected between June and September. In late autumn, the number of sick days taken is almost twice as high as in the …
Artery calcification is almost twice as common in night owls compared to early birds. Circadian function appears to be particularly important during the early stages of cardiovascular disease.

Researchers have discovered a new way that epithelial cells, which form layers in organs like the skin and stomach, attach to one another, and how they perceive growth signals at these attachments, helping them form tissues of the right size and shape. Researchers have discovered a new way that epithelial cells, which form layers in …

Researchers have increased the fatigue threshold of particle-reinforced rubber, developing a new, multiscale approach that allows the material to bear high loads and resist crack growth over repeated use. This approach could not only increase the longevity of rubber products such as tires but also reduce the amount of pollution from rubber particles shed during …
