Astronomers have found some of the strongest evidence yet that stars can swallow their own planets. A new study, published in Monthly Notices of the Royal Astronomical Society, supports the long-held belief that young stars ...

In 2008, while investigating a clandestine drug lab, forensic scientists from WA's ChemCentre found something odd—a pile of wet bark, stripped from a wattle tree and stewed.

Skipping a few meals here and there, or eating whenever one can make time in their schedule, might seem like a benign act. Research, however, shows that these habits are far from being harmless. A recent large-scale study ...

Earth was mostly devoid of oxygen for much of its 4.5 billion year lifetime. That is, until certain processes started to allow for the eventual buildup of oxygen up to the levels we have now (around 21% of the atmosphere). ...

While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have contributed to these shifts.

As our world's population grows, so does the demand for ammonia—a key ingredient in fertilizer. The International Renewable Energy Agency estimates that ammonia production must quadruple by 2050 to feed the increase in global ...

Solar flares are powerful bursts of radiation from the sun's surface, which can wreak havoc on Earth's power grids, damage orbiting satellites, and pose serious radiation risks to astronauts. Yet despite decades of study, ...

People often look to dogs' behavior, especially their facial expressions, for indications of their states of mind. Numerous studies show that this is a popular interpretation strategy. However, modern dog breeds vary greatly ...

In some parts of the world, autumn brings welcome relief from mosquitoes, such as the Northern house mosquito (Culex pipiens). As the days grow shorter, the waning light is a signal for them to enter a winter state of dormancy ...

Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of Engineering have stabilized a fleeting structural phase of matter that had been predicted theoretically ...

Cambridge scientists have grown miniature circuits in the lab that mimic how the brain and spinal cord connect, which underlies human movement. They used this model to show how damage to these connections previously considered ...

Researchers in Leiden have, for the first time, observed how a specialized enzyme helps bacteria stay alive when oxygen levels are low, and how that process can be blocked. The study, published in Science Advances, opens ...
