Large-scale genetic analyses are shedding new light on how human DNA shapes the gut microbiome. Drawing on data from 28,000 individuals, two international studies identify 11 genomic regions that influence which bacteria colonise the intestine and how they function.

A new study on the Antarctic Peninsula shows that the choices we make in the next decade will determine Antarctica’s fate for centuries. At the moment we are on track for a medium- to high emissions future with irreversible consequences.

Researchers have revealed that skin temperature influence REM sleep and sleep-related disorders. These new findings will help to better understand brain-body interactions that regulate sleep and provide novel therapeutic strategies for sleep-wake rhythm disorders such as narcolepsy.

Researchers have developed a new smartwatch that can continuously monitor blood pressure with clinical accuracy. The technology has the potential to revolutionize how cardiovascular health is managed.

Humans tend to fear bed bugs, and rightly so. The bloodsuckers are tough to get rid of once they’ve entered a home. But new research has, for the first time, identified one thing the bugs seem to fear — water and wet surfaces.

You don’t need to look like a bodybuilder, but for healthy aging, maintaining muscle strength is likely just as important as getting enough aerobic activity. That’s according to the findings of a University at Buffalo-led study of more than 5,000 women between the ages of 63 and 99.

Primary percutaneous coronary intervention is a life-saving procedure used to restore blood flow as soon as possible after the onset of a heart attack. A study has now revealed that increasing the number of coronary interventions in patients with acute myocardial infarction does not appear to reduce death rates.

Honey bees navigate with striking individual precision, according to a drone-based study by researchers at the University of Freiburg. High-resolution 3D tracking shows that each bee follows its own consistent route between hive and food source, using landscape landmarks to stay on course. The findings reveal far greater navigational accuracy than previously assumed from the waggle dance.

A new study, which included over 3 million adults who had the autumn 2022 vaccine in England, has revealed that the booster jab helped to reduce the risks of Covid 19–related hospitalization and deaths.

Long-term exposure to fine particulate air pollution is associated with a higher risk of Alzheimer’s disease, according to a large national study of nearly 28 million older adults in the United States.
