Researchers developed a fully integrated photonic processor that can perform all the key computations of a deep neural network on a photonic chip, using light. This advance could improve the speed and ...

As muscles age, their cells lose the ability to regenerate and heal after injury. Now, researchers have created the most comprehensive portrait to date of how that change, in mice, unfolds over time.

A theoretical study suggests that small black holes born in the early universe may have left behind hollow planetoids and microscopic tunnels, and that we should start looking within rocks and old ...

A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbor was once much more like Earth than it is today.

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 ...

When wild capuchin monkeys experience experience higher temperatures, the performance of their generalized immune system declines. This study illustrates how climate change many impact animals.

For pregnant women, exposure to fine particulate air pollution (PM2.5) was associated with altered immune responses that can lead to adverse birth outcomes, according to a new study. The study is ...

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 ...

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 ...

People who have chronic traumatic encephalopathy (CTE) who have a family history of mental illness may have a higher risk of aggression in middle age, according to a new study.
