Neanderthals split into distinct regional groups that developed genetic differences far sooner than modern human populations typically did, according to a study published in Proceedings of the National Academy of Sciences. ...

Imagine being able to assess how healthy the front of our eyes are not only in hospitals, but also in remote eye-screening camps, elderly-care facilities, pharmacies, or even train stations. That is the future a research ...

Through new improvements to existing AI models, researchers in China have created a framework that can methodically identify useful new forms of solid carbon. With their approach, Zhibin Gao and colleagues at Xi'an Jiaotong ...

Latin American people are represented in fewer than 4% of genetic epidemiological studies around the world. When they are included, they're often lumped together as one group, despite the rich diversity among different Latin ...

An international study published across 34 countries shows that the biological age of the brain can be accelerated or delayed by environmental risk (air pollution, public housing conditions) and protective factors (socioeconomic ...

When the environment changes dramatically, animals from mollusks to crows can make big changes in their behavior that enable them to survive. For example, marmots and ground squirrels in California are spending more time ...

Using high-intensity lasers, researchers have taken an important step toward miniaturization of particle accelerators by demonstrating free-electron laser amplification at extreme ultraviolet wavelengths (27–50 nm), with ...

Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending ...

Researchers have demonstrated a new class of low-cost, scalable sensors that can be used to monitor electrical activity in human cerebral organoids. Because electrical signals are key to understanding brain function, this ...

The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a voltage, RIKEN researchers have demonstrated. This could enable a new generation of optical devices ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing ...

Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays are interpreted across fields of physics, chemistry, biology and materials science, new research reveals. ...
