Tech Xplore / Foundation AI models trained on physics, not words, are driving scientific discovery
While popular AI models such as ChatGPT are trained on language or photographs, new models created by researchers from the Polymathic AI collaboration are trained using real scientific datasets. The models are already using ...
Tech Xplore / Powering AI from space, at scale, with a passive tether design
Penn Engineers have developed a novel design for solar-powered data centers that will orbit Earth and could realistically scale to meet the growing demand for AI computing while reducing the environmental impact of data centers.
Medical Xpress / CAR T-cell therapy improves symptoms of myasthenia gravis, clinical trial shows
A new study led by researchers at the UNC School of Medicine and Cartesian Therapeutics, found that immunotherapy can help people with generalized myasthenia gravis, a disease where the body accidentally attacks the cells ...
Phys.org / Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
Phys.org / Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural ...
Phys.org / Microplastics found in a third of surveyed fish off the coasts of remote Pacific Islands
A third of fish living in the remote coastal waters of the Pacific Island Countries and Territories are contaminated with microplastics, with especially high rates in Fiji, according to an analysis published in PLOS One by ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Novel nanomaterial uses oxidative stress to kill cancer cells
Scientists at Oregon State University have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the cells via oxidative stress while leaving healthy tissues alone. The study ...
Phys.org / Nutritious school-provided lunches top of the menu for Australian parents
As kids head back to school and attention returns to the daily grind of lunch boxes, new research reveals Australian parents are overwhelmingly supportive of school-provided lunch programs, with nutrition and variety their ...
Tech Xplore / Origami-inspired ring lets users 'feel' virtual worlds
Virtual reality (VR) and augmented reality (AR) are technologies that allow users to immerse themselves in digital worlds or enhance their surroundings with computer-generated filters or images, respectively. Both these technologies ...
Tech Xplore / Amorphous passivation strategy creates efficient, durable and flexible perovskite solar cells
Solar cells, devices that convert sunlight into electricity, are helping to reduce greenhouse gas emissions worldwide, promoting a shift toward renewable energy sources. Most solar cells used today are based on silicon, yet ...
Medical Xpress / Heart damage is common and often unnoticed after surgery, but those who see a cardiologist may fare better
An estimated 4.2 million people die within 30 days of surgery worldwide each year. A new study suggests that deaths and serious heart disease might be prevented if some patients see a specialist heart doctor as part of their ...
