Medical Xpress / 3D DNA switch in brown fat could reshape obesity and diabetes treatment
Most fat stores energy; the body's brown fat does the opposite. Unlike the white fat that accumulates just under our skin, brown fat burns calories and glucose to generate heat. Formally known as brown adipose tissue, it ...
Phys.org / Gene-sharing view challenged as bacteria shown to police DNA exchange
A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view ...
Phys.org / Chernobyl's exclusion zone is a beacon of biodiversity—but it faces new threats from Russia's invasion
April 26 marks the 40th anniversary of the explosion at Reactor 4 of the Chernobyl nuclear power plant in Ukraine. The accident caused the largest ever release of radioactive material into the environment, and at the time ...
Medical Xpress / Seven days without plastic contact slashes phthalates and bisphenols in body
A clinical trial investigating levels of plastic chemicals in the human body has found that a low-plastic diet could be a fast and effective way to reduce exposure.
Phys.org / Atomic-level snapshots reveal how a key copper enzyme powers nature's chemistry
Researchers from the University of Liverpool, Japan, and Argentina have captured atomic-resolution images of an important copper-containing enzyme using advanced X-ray Free Electron Laser (XFEL) technology at SACLA in Japan. ...
Phys.org / AI for molecular simulations may not need built-in physics to deliver strong results
Simulating how atoms and molecules move over time is a central challenge in computational chemistry and materials science. Classical machine learning approaches to molecular dynamics (MD) encode fundamental physical principles ...
Tech Xplore / Engineers boost sustainable acrylic acid production using next‑generation membrane reactor
Acrylic acid is essential for everyday products—from paints and coatings to absorbent polymers—yet almost all of it is currently made from propylene, a petrochemical. As global biodiesel production rises, so does the supply ...
Medical Xpress / Freeze-dried platelet product slows swelling and bleeding in traumatic brain injuries
A freeze-dried blood product that could be stored for years on ambulances or in remote emergency departments is showing promise at treating traumatic brain injuries. The news comes from a mouse study done by researchers at ...
Phys.org / Photonic chip generates milliwatt-level UV light, 100 times brighter than before
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique ...
Phys.org / Machine learning helps detect roars from lion collars without recording actual audio
Roaring over long distances is a key behavior of lions. They communicate within prides as well as with other animals using distinct sequences of moans and grunts. Scientists from the GAIA Initiative have now published a machine ...
Phys.org / ATLAS sets record limits on Higgs boson's self-interaction
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This "self-coupling" could help explain the evolution of the early universe and the mechanism that gives mass to elementary ...
Medical Xpress / Unexpected cancer mutations in brain's immune cells may help fuel Alzheimer's disease
As the body ages, cells naturally accumulate dozens of genetic mutations each year. New research from Boston Children's Hospital, published in Cell, finds that the brain's resident immune cells, microglia, amass mutations ...
