Opening the door to a good night's sleep

A popular fitness trend among young people may be quietly undermining their sleep. A new study led by researchers at the University of Toronto has found that teenagers and young adults who use pre-workout supplements are significantly more likely to experience extremely short sleep durations.

Scientists have discovered new anti-ageing compounds produced by a little-studied blood bacterium, opening up promising avenues for future skin-rejuvenation therapies.

A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely affected patients.

New research has uncovered a powerful link between nighttime heart rhythm and future health conditions, even in people with no obvious sleep problems

Researchers are working to improve the way we use evolutionary modeling to understand drug resistance. The study uses a "fitness seascape" evolutionary model to predict whether an infection will develop antibiotic resistance. It found that inconsistent timing and missing early doses can lead to treatment failure.
