An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in ...

Researchers at the National Graphene Institute have shown that naturally occurring channels within a common clay mineral can respond to pressure, voltage and pH, offering possibilities for controlling the movement of ions ...

Porous liquids combine permanent nanoscale cavities with fluidity, making them promising for applications like carbon dioxide capture, gas separation and other chemical processes. Their viscosity must be tailored to the intended ...

A new study published in Science Advances reveals how Bronze Age communities in Central Europe adapted to changing environmental and social conditions by adopting broomcorn millet, a fast-growing, climate-resilient crop.

Humanoid robots, robotic systems with limbs and body structures that resemble those of humans, could tackle various manual tasks in homes, workspaces and other settings. Yet teaching these robots to reliably perform different ...

Until just over a decade ago, ring systems were thought to be exclusive to the giant planets of the solar system, such as Jupiter, Saturn, Uranus and Neptune. However, in 2013, a small body barely 250 kilometers (155 miles) ...

During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help wash away this waste, keeping the brain healthy.

Just a few atomic layers at the surface can strongly influence how effectively a material binds pollutants from water or how efficiently a photocatalyst responds to light. Researchers at the Fraunhofer Institute for Applied ...

Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started ...

Cadmium is a naturally occurring, toxic heavy metal found in many soils across Latin America and the Caribbean, where cacao trees are widely cultivated. It makes its way into cocoa seeds, called beans, that are roasted and ...

Scientists from the Denver Museum of Nature & Science and Liverpool John Moores University in England have discovered the first adult T. rex trackway, providing insights into how this emblematic predator moved. The findings ...

Using NASA's Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, ...
