What makes glass good at conducting heat? Sound holds the key

Glass can keep a drink safely contained, protect a smartphone screen, or serve as a foundation for electronic components. But when it comes to controlling heat, this familiar material still holds some scientific mysteries. Now, researchers have identified a key factor governing how efficiently heat travels through silicate glass, offering a new guideline for designing glass materials for next-generation electronic devices.

When computer science meets the alpaca immune system

After earning bachelor's and Ph.D. degrees in bioengineering with a focus on molecular biology, Will White, a postdoctoral scholar in the Department of Computer Science at Tufts, was pretty certain his future research would involve things like DNA and proteins. What he didn't know was that alpacas would also be part of the equation.

US drinking water could contain double the reported PFAS levels, model estimates

Common ways of reporting perfluoroalkyl and polyfluoroalkyl substances (PFAS)—the man-made, so-called forever chemicals that pose environmental and health threats—could underestimate the concentration of PFAS in U.S. drinking water by as much as half, according to a study being published Oct. 23 in Cell Reports Sustainability.

DNA programs a cell-free material to build its own motors and move

Researchers have created a material that manufactures the proteins responsible for cell movement, without needing intact living cells. By embedding cell-free gene expression into a thin sheet of protein filaments, they were able to make the material wrinkle, rise into blister-like shapes and break into bundles that flow around one another.

Artemis I: Crystals of experimental detectors record radiation doses near the moon

Do cosmic radiation doses near the moon differ significantly from those received by astronauts in low Earth orbit? Experimental lithium fluoride detectors, installed aboard the Orion spacecraft during the Artemis I mission, have now made it possible to obtain preliminary estimates.

Elusive uranium 'sandwich' molecule isolated after more than 50 years

In a study published in Nature Communications, researchers from The University of Manchester and Lancaster University have isolated and characterized uranocenium, the positively charged form of a landmark uranium compound called uranocene. The work shows that this long-sought molecule is stable, and that it behaves in a way that challenges how chemists usually think about bonding in heavy elements.

Open-source workflow makes spatial proteomics easier to use

Fabian Coscia and his team have published in Nature Methods an open-source workflow that makes Deep Visual Proteomics easier to use, adapt and scale. OpenDVP enables scientists to spatially map thousands of proteins inside cells and their cellular environments, while preserving their tissue context.

Archimedes screw inspires single-molecule motor powered by electric current

Molecular machines are regarded as the next step in miniaturization. Their models can be found in living cells, where molecular motors convert energy and generate movement. Scientists have been working for decades to artificially replicate such systems. The 2016 Nobel Prize in Chemistry was awarded for this research.

ALMA spots 'dragon egg' that may represent the earliest stages of massive star formation

Astronomers identified an exceptionally tiny core that may represent an early stage in the formation of a massive star. Located in an infrared-dark area called Dragon Cloud, the core is nicknamed the "dragon egg." The paper, accepted for publication in Astronomy & Astrophysics, was posted to the arXiv preprint server on Oct. 5.

Strategic new protections could link 13 Pacific deep-sea reserves into connected network

Protected areas have been set up to shield deep-sea life from the impacts of seabed mining in the Pacific Ocean. However, new research led by scientists at Plymouth Marine Laboratory (PML) and published in Nature Ecology & Evolution highlights an opportunity to make these protections even more effective.

Marine heat waves suppress nutrient use, reproductive flexibility in humpback whales

A new study led by University of Hawai'i (UH) at Mānoa researchers reveals how extreme ocean warming disrupts whale metabolism, nutrition and reproductive success and what the developing 2026–2027 El Niño could mean next. As climate change drives increasingly intense marine heat waves, scientists are uncovering how these extreme warming events disrupt the biology of humpback whales.

AI is solving math problems that stumped humans. What comes next?

A few short years ago, asking AI to add two four-digit numbers together for a third-grade math assignment would have been a bad idea. Over half the time, the answer would be wrong, studies have shown. Long division or a "leaky tank" problem, an algebra class staple? Forget about it.

Scientists find key to predicting some El Niño events 12 months ahead

Scientists have identified the conditions that make it possible to predict some El Niño and La Niña events up to a year in advance, potentially giving communities and decision-makers significantly more time to prepare for weather extremes.

Paleolithic human DNA reveals east-west connections across Ice Age Europe

More than 30,000 years ago, people associated with one of Europe's major Paleolithic cultures (the Gravettian) were more interconnected than previously thought. An international research team led by the University of Vienna has uncovered new genetic evidence of long-distance connections between these populations. Published in Science Advances, the study combines genomic data from rare human remains with human DNA preserved in cave sediments.

An ancient virus in chimpanzee DNA switches off a gene that is active in humans

Humans and chimpanzees share almost all their genes. Despite this, our brains have developed in different ways. Researchers at Lund University in Sweden have now shown that a viral pandemic dating back several million years is likely to be part of the explanation.
