Phys.org / Factory farming in Africa: Development banks see it as a good idea, but it's bad for the climate
In sub-Saharan Africa, pastoral livestock farming—where cattle, goats and sheep roam freely across grasslands, grazing at will—has been the main form of livestock production. It has been a source of livelihoods for centuries, ...
Medical Xpress / Stem cell organoids mimic aspects of early limb development
Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing how a specialized signaling center shapes both cell identity and tissue organization.
Tech Xplore / Artificial tendons give muscle-powered robots a boost
Our muscles are nature's actuators. The sinewy tissue is what generates the forces that make our bodies move. In recent years, engineers have used real muscle tissue to actuate "biohybrid robots" made from both living tissue ...
Medical Xpress / Single dose RSV vaccine protection found to wane over 18 months
Research led by the Veterans Affairs Portland Health Care System in Portland, Oregon, found that a single dose of respiratory syncytial virus (RSV) vaccine reduced RSV infections and RSV-related emergency visits, hospitalizations, ...
Phys.org / What time is it on Mars? Physicists have the answer.
Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks.
Medical Xpress / Fatty food smells during pregnancy may raise obesity risk in offspring
A research team at the Max Planck Institute for Metabolism Research has found that the smell of fatty foods during pregnancy increases the risk of overweight and obesity in children. The researchers fed pregnant mice a healthy ...
Phys.org / Wetlands trap toxic metals after battery plant fire scatters debris
When fire broke out at the world's largest battery energy storage facility in January 2025, its thick smoke blanketed surrounding wetlands, farms and nearby communities on the central California coast.
Phys.org / New code helps scientists map dark matter halos
Dark matter and its impact on cosmology have puzzled physicists for nearly a century. At Perimeter Institute, two researchers are trying to better understand how one potential dark matter candidate, self-interacting dark ...
Phys.org / Detecting strong-to-weak symmetry breaking might be impossible, study shows
When a system undergoes a transformation, yet an underlying physical property remains unchanged, this property is referred to as "symmetry." Spontaneous symmetry breaking (SSB) occurs when a system breaks out of this symmetry ...
Tech Xplore / Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds
Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, ...
Phys.org / How supplemental feeding boosts reproductive conditions of urban squirrels
Urbanization is rapidly growing worldwide, often bringing negative effects on wildlife through loss of habitat and disturbances such as light pollution and noise. Yet some species manage to adapt to cities, either due to ...
Medical Xpress / How fast you can walk before hip surgery may determine how well you recover
Total hip arthroplasty (hip replacement) is a common treatment for hip osteoarthritis, a degenerative joint disease caused by cartilage in the hip joint wearing down. However, clinical outcomes vary between patients, and ...
