Electrochemical method supports nitrogen circular economy

Imagine a world where industrial waste isn't just reduced, it's turned into something useful. This kind of circular economy is already in the works for carbon. Now, researchers at Washington University in St. Louis have developed ...

First ancient genomes from the Green Sahara deciphered

An international team led by researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has sequenced the first ancient genomes from the so-called Green Sahara, a period when the largest ...

Sampling the plumes of Jupiter's volcano moon, Io

What can a sample return mission from Jupiter's volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th Lunar and Planetary Science ...

How can we find cryovolcanoes on Europa?

In the 1970s, NASA's Voyager probes passed through Jupiter's system and snapped pictures of its largest moons, also known as the Galilean moons. These pictures and the data they gathered offered the first hints that a global ...

A dramatic Einstein ring seen by Webb

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was first observed in 1919 during a total solar eclipse. Since stars appear as points of light, the effect ...

The rivers that science says shouldn't exist

Rivers join downstream, flow downhill, and eventually meet an ocean or terminal lake: These are fundamental rules of how waterways and basins are supposed to work. But rules are made to be broken. In the journal Water Resources ...

Antitrust settlement could lower cost of buying a home

Since the National Association of Realtors (NAR) agreed in March to pay $418 million to settle an antitrust lawsuit, researchers at Texas McCombs see the potential to curb artificially high real estate commissions.

A new wave in ultrafast magnetic control

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method to study ultrafast magnetism in materials. They have shown the generation and application of magnetic ...

Miso made in space tastes nuttier, researchers find

Miso is a traditional Japanese condiment made by fermenting cooked soybeans and salt. In a study published in iScience, researchers successfully made miso on the International Space Station (ISS). They found that the miso ...

How do coconuts get their water?

Coconut trees are iconic plants found across the world's tropical regions. They're called "nature's supermarket" or the "tree of life" in several cultures because every part of the coconut tree is used. Its leaves can be ...

Biodegradable nails make manicures more sustainable

Sit down, relax and get your nails done at the sustainability salon. In a new study, a team of researchers at the University of Colorado Boulder's ATLAS Institute has designed a new kind of press-on nails that are biodegradable, ...

Nurses and AI collaborate to save lives and reduce hospital stays

An AI tool that analyzes nurses' data and notes detected when patients in the hospital were deteriorating nearly two days earlier than traditional methods and reduced the risk of death by over 35%, found a year-long clinical ...

Gliding avalanches: Field monitoring tackles the great unknowns

In a gliding avalanche, the entire snowpack slides down a suitable substratum such as grass or slabs of rock. Such avalanches are always released naturally. This requires the snow on the ground to become moist. In winter, ...

X-ray spectroscopy reveals unexpected proton attraction

Proton transfer in aqueous systems is a fundamental process occurring constantly around us. It involves a molecule losing a proton, which then associates with another molecule. Given its significance in fields such as electrochemistry, ...
