Researchers have analyzed water samples collected during two expeditions aboard the research icebreaker Polarstern to investigate how life and changing conditions on the Antarctic continental shelf affect carbon carried into the deep ocean. Published in Nature Communications, the
The genetic code determines the correspondence between genetic instructions and amino acids—the building blocks that form proteins. How this correspondence arose is one of the major open questions in evolutionary biology. A study led by Dr. Lluís Ribas de Pouplana, ICREA research
Men in treatment for domestic violence have an elastic view of what constitutes consent in their partner, an UdeM study has found.
Almost two in three respondents surveyed in Australia's remote First Nations communities did not have working free-to-air television, a study has found.
Long before birds took to the skies, dinosaurs were already sporting feathers. But exactly how they evolved into the sophisticated structures that allow birds to fly remains something of a mystery. Now, the discovery of the longest feather ever found preserved in amber is providi
A fresh excavation of the eastern deposit at Riparo Mochi, a rock shelter near today's French–Italian border, has pushed back the timeline for when Ice Age hunter-gatherers from Spain first entered Italy.
Most of us spend much of our day staring at organic light-emitting diodes, or OLEDs, which convert electricity into light to produce the colorful displays on smartphones, computer monitors and televisions. Although metal-free light-emitting materials that produce all colors are i
At first glance, the canal near which Ibrahim Yildiz grazes his sheep in the southern Adana province appears idyllic, framed by rows of clementine trees—until the mountains of plastic shavings come into view.
Light-pulse pairs reveal the femtosecond decay of an inner-shell hole in xenon atoms and more — today's news signal.
Researchers at the UVSOR Synchrotron Facility (Institute for Molecular Science, Japan) and partner institutions have observed the decay of a xenon 4d core hole, an inner-shell vacancy, directly in the time domain. They used pairs of phase-coherent extreme ultraviolet pulses from
Dehydrating milk to turn it into powder is, today, an energy-intensive process that subjects the product to high temperatures. Powdered milk is widely used by the food industry and allows the product to be stored and transported in a stable condition for long periods of time with
Every time your heart beats, your lungs expand, or your skin stretches, a remarkable protein called elastin helps your body return to its original shape. But what exactly gives this protein its elasticity? For more than 50 years, scientists have debated whether elastin's ability

Shoppers often greet the closure of a Walmart with dismay, while competitors find cause to celebrate.
Researchers at the U.S. Department of Energy's (DOE) Ames National Laboratory have discovered a way to control the handedness of magnons, tiny magnetic waves that can carry information through materials. By changing the material's magnetic state with an external magnetic field, t
An international collaboration demonstrates that classical nonlinear dynamics can drive single- and two-photon states to thermalize, opening new avenues for simulating complex quantum many-body systems within accessible optical architectures.
Artificial intelligence use among university students is now near-universal in many countries. Yet, as of a year ago, fewer than one in five universities in a 90-country UNESCO survey had a formal AI policy.
A new study suggests that most of Earth's carbon originated in the outer solar system and didn't arrive here until the late stages of planetary development. The study, led by researchers at Yale and Columbia, is based upon an analysis of magma droplets called "melt inclusions" fr
The poles, or ends, of rod-shaped bacteria have been imaged at molecular resolution for the first time in a new study led by UCL (University College London) researchers. The study, published in the journal Nature Communications, used a new technique to keep live bacteria in place
Researchers from King's College London and Rutgers University in New Jersey created a modified enzyme (a protein that speeds up chemical reactions) that breaks down polyethylene terephthalate (PET) plastic 10 times quicker, using 10 times less enzyme. They accomplished this just
A review published in the International Journal of Managerial and Financial Accounting on the subject of greenwashing in financial services has found that financial institutions often claim environmental responsibility while continuing to finance high-carbon projects.

Astronomers may have solved one of the biggest mysteries uncovered by NASA's James Webb Space Telescope (JWST), using sophisticated simulations to show that enigmatic objects known as "little red dots" (LRDs) are likely the birthplaces of the first supermassive black holes.
Cells share small molecules with their neighbors through tiny tunnels made of proteins arranged in a ring. Research at Nagoya University suggests that the tails of the proteins must link up to form an inner ring for the tunnel to become evenly round—a previously unknown step in h
