Phys.org / Wasp spider reveals rapid genetic adaptation during decades-long march into northern Europe
It has taken only a few decades: The wasp spider (Argiope bruennichi) has expanded its range from the Mediterranean region to northern Europe—even as far as southern Finland. In doing so, it has adapted genetically much faster ...
Tech Xplore / Ultra-thin MoS₂ computer packs 1,400 transistors onto one chip
The rapid advancement and diffusion of artificial intelligence (AI) systems, such as the machine learning models underpinning the functioning of ChatGPT, Gemini and similar platforms, have posed new demands on the electronics ...
Phys.org / Is your dog a lefty? New 'Doginburgh' test captures paw preference
Just like left- or right-handed humans, domestic dogs have a preference for their left or right paw, a trait known as laterality. This can vary depending on the tasks they perform, which has made it difficult to create a ...
Medical Xpress / Stem cell embryo models could unlock infertility clues beyond 14-day research limit
An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, coordinated by UPF researcher ...
Medical Xpress / Engineers find a way to deliver drugs directly to the esophagus
There are few treatment options available for people with disorders of the esophagus. Delivering drugs directly to this part of the body is difficult, so patients are usually treated with systemic drugs, which can have unwanted ...
Phys.org / Cosmic dawn fuel discovery unlocks early galaxy growth secrets
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy. The team, led from Leiden University, focused on REBELS-25, seen when the ...
Medical Xpress / Why women with HIV are still dying early, even when virus is not main cause
Women with HIV most often die from preventable, trauma-related conditions like substance use and mental illness—not the virus itself. Yet these leading causes are largely missing from official death records, according to ...
Medical Xpress / Why tiny amounts of vitamin B12 matter more as we age
Two micrograms is an almost unimaginably small amount. It weighs less than a tiny fragment of a grain of table salt. Yet adults need only around this amount of vitamin B12 each day, depending on the guideline used, to support ...
Phys.org / Newfound sound wave scattering rule may lead to less bulky, more effective soundproofing
Researchers in China recently uncovered a quantum-inspired rule governing how sound is scattered by certain physical properties of a material. Their research, published in Physical Review Letters, may lead to the ability ...
Medical Xpress / Flu infection may weaken tuberculosis defenses by disrupting key immune pathways
New research from Imperial College London suggests that infection with the influenza virus may leave people more susceptible to tuberculosis. The findings suggest that seasonal flu vaccines could offer a potential new strategy ...
Phys.org / Massive Kamchatka earthquake has extended rupture that overlaps 1952 event, researchers find
Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8 Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers (311 miles) from its epicenter.
Phys.org / Light echoes reveal possible dark matter buildup around supermassive black holes
We may not know what dark matter is, but we keep getting whiffs of it. "We are reaching a point where the observational evidence for dark matter is simply undeniable," said Mayank Sharma, a Virginia Tech graduate student ...
