Medical Xpress / Sleep disorders don't just exhaust you, they change your brain
Sleep disorders may do more than leave people feeling tired. New research from Florida International University shows that sleep disorders are associated with structural changes in brain regions involved in attention, motivation ...
Phys.org / T. rex babies were born ready to run and feed themselves
Tyrannosaurus rex was a giant of the prehistoric world, standing up to 13 feet (4 meters) tall and weighing around 9 tons (8 tonnes). So you might expect that its hatchlings were also a considerable size.
Phys.org / Natural peptide switches from calmodulin to the cancer-associated protein midkine depending on the ion environment
Proteins regulate a wide range of biological processes inside and outside cells by binding to specific molecular partners. In recent years, short peptides that can selectively recognize disease-related proteins have attracted ...
Medical Xpress / Sweeteners slow growth of important gut bacteria in lab tests
Cambridge researchers have shown how commonly used sweeteners slow the growth of certain gut bacteria. One sweetener in particular—isosteviol—when combined with the antidepressant duloxetine, significantly impaired two important ...
Phys.org / Americans increasingly view illicit drug policy through a partisan lens, new analysis finds
Since the early 1970s, when the Nixon administration launched the "war on drugs," Gallup has been asking Americans how they feel about problems surrounding illicit drugs. But the war has not gone well and Gallup's surveys ...
Medical Xpress / Study reveals why some colorectal cancers respond better to immunotherapy
A subset of cancers, known as microsatellite instability (MSI) and deficient DNA mismatch repair (dMMR) cancers, are more visible to the immune system than others. Because their DNA repair systems are defective, these tumors ...
Tech Xplore / For energy systems that power a reliable grid and avoid blackouts, the future is all about location
Will a warming climate and changing weather patterns lead to more grid blackouts and other energy disruptions? Answering that question requires studying both regional climate forecasts and local energy systems, including ...
Phys.org / How NASA's Artemis III lander test will pave way for moon landings
Before Artemis astronauts land on the moon's surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial ...
Phys.org / Genetic databases as the key to global benefit-sharing
An international research team led by the Science Policy and Internationalization Department at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures has published a practical guide in the journal ...
Phys.org / Crab-dug tunnels boost methane-eating microbes in coastal wetlands, study finds
Wetlands are a significant producer of methane, a greenhouse gas more potent than carbon dioxide. Yet not all of it escapes into the atmosphere. One reason is crabs. A study published in the journal Environmental Science ...
Tech Xplore / Sun-tracking solar panels fold away from hail while lifting output nearly 40%
Researchers led by Armin Buchroithner from the Institute of Electrical Measurement and Sensor Systems at TU Graz have developed an innovative photovoltaic system that combines significantly higher output with protection from ...
Medical Xpress / What's driving the obesity pandemic?
New research presented at the International Congress on Obesity (ICO2026), hosted by the World Obesity Federation (WOF) in Mexico City, Mexico, (15–17 July) asks what is driving the obesity pandemic.
