Researchers have created the smallest walking robot yet. Its mission: to be tiny enough to interact with waves of visible light and still move independently, so that it can maneuver to specific ...

The melting of Greenland is accelerating, with an estimated loss of between 964 and 1735 gigatons of ice per year by 2100 in a scenario of high greenhouse gas emissions (SSP585), according to three ...

Researchers have analysed the effects of seven different hormone treatments for menopausal symptoms on the risk of blood clots, stroke and heart attack. The study, which involved around one million ...

Bacteria modify their ribosomes when exposed to widely used antibiotics, according to new research. The modified ribosomes have changes specifically in the regions where antibiotics latch on to and ...

A chemical reaction can convert two polluting greenhouse gases into valuable building blocks for cleaner fuels and feedstocks, but the high temperature required for the reaction also deactivates the ...

A recent trial finds an injection given during some asthma and COPD attacks is more effective than the current treatment of steroid tablets, reducing the need for further treatment by 30%.

Recent results from a recent clinical trial indicate that a twice-yearly injection of Lenacapavir offers an overall 96% reduced risk of acquiring HIV. This makes Lenacapavir significantly more ...

To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mystery: scientists ...

Soccer players who headed the ball at high levels showed abnormality of the brain's white matter adjacent to sulci, which are deep grooves in the brain's surface. Abnormalities in this region of the ...
