Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic "forever chemical" around the globe, a new study shows. Atmospheric scientists, ...
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Sleep is essential for much of the animal kingdom. During the night, neuron and tissue repair mechanisms are activated to aid recovery from daily activity. This is risky: organisms that sleep are more vulnerable to predators. ...
Australian researchers have developed a high‑performance coating made from peppermint essential oil that can be applied to the surfaces of many commonly used medical devices, offering a safer way to protect patients from ...
University of Queensland research has confirmed Brisbane's only dinosaur fossil is Australia's oldest, dating back to the earliest part of the Late Triassic period 230 million years ago. The 18.5-centimeter footprint was ...
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture ...
Mexican long-nosed bats have a taste for agave, their tongues designed to lap up the famous desert plant's nectar during nightly flights. It's not just a means of satisfying taste buds. It's a matter of fueling up for an ...
Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 (M87) in the constellation Virgo is visible over distances of 3,000 light-years and can be ...
Researchers at the Technical University of Munich (TUM) have identified a bacterial genus that promotes root growth and nitrogen uptake in plants. The findings open new possibilities for developing customized "plant probiotics" ...
A relatively simple statistical analysis method can more accurately predict the risk of landslides caused by heavy rain, according to a study coordinated by Brazilian researchers affiliated with the Institute of Mathematical ...
