Phys.org / Over the past 15 years, Brazil has seen a more than 200% increase in non-native mollusk species
A study published in the journal Biological Invasions indicates that Brazil currently has at least 82 non-native mollusk species, in addition to 13 whose origin cannot be determined. This represents a 215% increase compared ...
Phys.org / A single origin story for the Milky Way's most mysterious stars
Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied ...
Medical Xpress / Bioresorbable implant electrically stimulates organs, nerves and muscles then vanishes after treatment
To treat or manage various heart, gastrointestinal and neurological conditions, including arrhythmias, heart block, gastroparesis, epilepsy and some nerve injuries, doctors rely on a technique known as electrical stimulation. ...
Phys.org / Computer scientists develop a new AI tool that rivals AlphaFold 3 in mapping RNA
The same family of artificial intelligence that powers today's image generators is now being aimed at one of biology's hardest puzzles: the ever-changing, three-dimensional shapes of RNA. These are the molecules behind mRNA ...
Science X / Kids shrug off sunk-cost bias until about age 6, behavioral experiments reveal
Ever wonder why adults cling to things in which they've invested time or effort? In behavioral experiments, people often predict that they would stick with an option just because it was harder to get. Psychologists call this ...
Phys.org / 'Stop the war!': The paradox of 'pressure petitions'

Medical Xpress / New listeria labeling proposed for smoked salmon and other ready-to-eat foods
Researchers from the DTU National Food Institute are proposing a new labeling scheme designed to give consumers a better opportunity to choose ready-to-eat foods, such as smoked salmon and spiced pork roll, without risking ...
Phys.org / Rice grown on the moon? Air-to-fertilizer technology helps rice grow in lunar soil simulant
Securing sustainable food supplies is a key challenge for long-term human exploration and potential habitation of the moon. The moon's soil contains no organic material, and essential plant nitrogen sources like ammonia and ...
Phys.org / Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this ...
Phys.org / Scientists devise new method for tracing environmental PFAS contamination better
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in industrial processes and consumer products because of their resistance to heat, water and oil. However, these same properties ...
Medical Xpress / Lab-grown retinal cells show promise for new eye therapies
Biomedical engineers at Duke University have used induced pluripotent stem cells (iPSCs) to grow specialized blood vessel cells critical to retinal health for the first time. When injected into mouse models of retinal disease, ...
Tech Xplore / Laser-based projection system uses light to guide workers through warehouses
Businesses are facing an increasing shortage of skilled workers. In some industries, like the logistics sector, specialists are so scarce that many companies have to rely on career changers and unskilled workers. What's more, ...
