Medical Xpress / From gut to brain: Scientists engineer bacteria to treat severe liver-related brain dysfunction
When the liver fails, toxins—such as ammonia—that should be filtered from the blood build up and reach the brain. The result is hepatic encephalopathy (HE), a devastating neurological complication of liver disease that can ...
Phys.org / 'Aquila Booster' challenges theoretical limits of particle acceleration in pulsar wind nebulae
The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron ...
Medical Xpress / Climate change a global threat to brain health, stroke experts say
The World Stroke Organization is warning that climate change poses an escalating threat to brain health, with extreme heat in particular increasing the risk of having a stroke and of patients dying from stroke.
Phys.org / Diving robot explores mystery of France's deepest shipwreck
Deep below the surface of the Mediterranean off the French coast, the pincer of a remotely guided underwater robot delicately closes around a centuries-old jug lying near a 16th-century shipwreck.
Phys.org / New approach to detect ultra-rare part-per-sextillion isotopes could also sharpen dark matter searches
The detection and study of isotopes, atoms of the same element that have different numbers of neutrons, could expand the scope of physics research and enable new scientific discoveries. So far, rare isotopes have been primarily ...
Medical Xpress / Age, sex, and cancer type can influence risk of subsequent cancers among survivors
The risk of developing a subsequent primary cancer varied significantly by age at initial diagnosis, sex, and type of first cancer, according to a study by Oxana Palesh and Susan Hong and colleagues at Virginia Commonwealth ...
Medical Xpress / Does vaping help people quit smoking? Maybe, findings suggest
A new review paper in Nicotine and Tobacco Research, finds that while research has previously found that vaping is associated with subsequently quitting smoking, that may not always be true. In fact, it appears studies limited ...
Phys.org / Research reveals why beavers are getting busy sooner in spring
A University of Alberta study has whittled down climate-related reasons beavers are emerging earlier onto the ice from their lodges in the spring—a shift that helps them store more winter food but could also lead to more ...
Phys.org / Mining critical materials is creating 'sacrifice zones' that harm water and health of world's poor
There is a troubling contradiction at the heart of the global transition to a cleaner, greener, tech-driven future: Modern technologies—everything from AI to wind turbines, as well as cellphones, electric vehicles and defense ...
Science X / Future-focused negative thoughts undercut present joy predicts depression more strongly than researchers expected
Imagine you are at a party having the time of your life—then you start thinking about the fact that these good feelings will fade as soon as it ends, triggering those good feelings to diminish in the moment. A recent article ...
Phys.org / Organic matter diversity determines how much iron is available for marine life, study finds
How much of the essential trace element iron remains available for marine life in the ocean depends critically on the diversity of organic molecules in seawater, according to new research published in Nature Communications ...
Tech Xplore / Molecular interface tweak unlocks more reliable perovskite solar cells, challenging common assumption
Perovskite solar cells are a rapidly advancing photovoltaic technology that has seen a dramatic rise in power conversion efficiency in recent years. A key driver of this progress is the use of molecular charge-selective contacts—ultrathin ...
