Phys.org / When seeds mislead, weeds succeed: Researchers uncover surprising ways weeds spread
Biologists have long thought that seed traits, such as the presence of wings, are the key to predicting in what way, and how far, weeds can disperse. Now, a trio of researchers has revealed that unexpected modes of seed dispersal ...
Phys.org / Capable CEOs communicate climate risks more consistently
Climate disclosures help investors and the public understand how companies view risks such as extreme weather, carbon regulation and the transition to cleaner energy. "Because these risks are uncertain and forward-looking, ...
Phys.org / ESA officially adopts ARRAKIHS mission: EU leads the exploration of the low surface brightness universe
The European Space Agency (ESA) has officially adopted ARRAKIHS as a scientific mission, confirming the target launch date of 2030. Matthieu Schaller is part of the science team: "I look forward to learning more about the ...
Tech Xplore / New water-based material could store solar energy, power reactions in darkness, then recharge
Northwestern University scientists have developed a new liquid material that charges like a battery, transforms like a living organism and then resets itself in open air. Traditionally, harvesting energy, storing it and using ...
Phys.org / How bacteria use acetyl coenzyme as a building block in the formation of cells
Researchers at the University of Greifswald have discovered a new mechanism by which bacteria such as Bacillus subtilis can regulate the production of the central metabolic molecule acetyl coenzyme A (Acetyl-CoA). Acetyl-CoA, ...
Phys.org / Silent prions reveal new cross-species chronic wasting disease risk in lab tests
Chronic wasting disease (CWD) is generally associated with animals. But a new study by researchers from the University of Calgary and international collaborators explored the potential for CWD to spread from deer, elk and ...
Tech Xplore / Light rewrites magnetic memory in one pulse, opening path to lower-power AI chips
As artificial intelligence, cloud computing and digital services continue to expand, the world is facing a growing need for faster and more energy-efficient ways to store and process information. A team led by the National ...
Phys.org / Collapsing stars could spawn mini-universes, offering new path to gravastars
Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses ...
Phys.org / Salmonella genomes reveal 45 previously unknown toxins in foodborne bacteria
Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research ...
Phys.org / Diffusion model links foam physics to voting shifts and market behavior
A drop of dye added to a glass of water undergoes ordinary diffusion. However, when placed on the surface of a foam, the dye spreads differently—diffusion becomes anomalous. An example of this is the pattern on the froth ...
Medical Xpress / New antibody may boost KRAS-targeted lung cancer treatment after resistance emerges
An experimental antibody treatment that binds to a protein known as PCDH7 shrank tumors in preclinical models of non-small cell lung cancer (NSCLC), including those resistant to a targeted therapy, a study led by UT Southwestern ...
Medical Xpress / Researchers identify brain 'entrapment' patterns associated with depression
Researchers at the Icahn School of Medicine at Mount Sinai have identified distinctive patterns in how the brain transitions between activity states in people with depression, providing new insight into why depressive symptoms ...
