Chronic oral inflammation may impair female fertility by triggering a systemic immune response that affects the ovaries. A new study shows this leads to oxidative damage, reduced egg quality, disrupted follicle development and reduced live birth rate. These findings point to a potential biological link between oral health and unexplained infertility, opening new directions for future treatments.

College students feel more pressure to be perfect than they did a generation ago, finds research published by the American Psychological Association. That increase in perfectionism may be tied to social and economic factors such as rising inequality and slowing economic growth, the researchers found.

Researchers have found that your heart already has its own 'natural bypass' system that can predict whether the heart muscle beyond it is alive or dead. A new study reveals how tiny hidden vessels could hold the key to deciding who really needs complex and risky surgery - and who doesn’t. The team found that a simple angiogram scoring system could help identify patients whose heart muscle is still alive - even when a major artery has been completely blocked for months. It is hoped that the breakthrough could change how cardiac patients are treated.

University of Michigan Health hepatologist Anna S. Lok, M.D., hails newly announced results of the B-Well clinical trials as “a major step toward a functional cure for hepatitis B virus infection," in an editorial published in the New England Journal of Medicine.

Extreme heat, natural disasters, food insecurity: climate change is known to have serious consequences for human physical health. In many places, scientific findings are being used to develop adaptation strategies and to mitigate the consequences of climate change for human health. But what about mental health? Research in this field is still in its early stages. As a result, climate, health and development policy also lacks strategies for prevention and treatment. To draw attention to this area of research, the German National Academy of Sciences Leopoldina and the Academy of Science of South Africa (ASSAf) are opening the discussion in an international virtual panel discussion on Tuesday, 9 June.
