Medical Xpress / A gut's complex architecture, recreated on a microscope slide–sized chip
Gut instinct, gut feeling or gutting it out—what exactly is the human gut? It's the workhorse of the digestive system and home to a vast, dynamic community of microorganisms that influence human health. In fact, the human ...
Tech Xplore / Chatbot gives teens first-hand experience of cybergrooming tactics without the risk of harm
Virginia Tech researchers are developing virtual tools to help teens protect themselves against cybergrooming. Using survey data from parents and teens and leveraging artificial intelligence, the research team created a chatbot ...
Phys.org / 'Born-again' star offers rare chance to watch stellar evolution in real time
Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.
Phys.org / Peer sexual harassment emerges early, highlighting need for prevention before Grade 4
Sexual harassment between peers begins as early as Grade 4 and continues throughout lower secondary school. Most of those who sexually harass others have also experienced harassment themselves. These are among the findings ...
Phys.org / Hot electrons reveal electronic collisions may raise resistance in twisted graphene
When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, ...
Medical Xpress / Running marathons with type 1 diabetes can be safe, small study shows
New research to be presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy, from Sept. 28–Oct. 2 shows that, with the use of continuous glucose monitoring (CGM) devices, ...
Phys.org / Astronomy's decades-long quest to understand cosmic topology
If some aspects of cosmic topology turn out to be true, the idea that starships might voyage across the cosmos for hundreds of thousands of light-years without ever returning to the same neck of spacetime could be problematic.
Phys.org / Heat-stable enzyme from deep-sea microbe turns nitrogen gas into ammonia
Microorganisms can do remarkable things—for example, nitrogen fixation, the conversion of nitrogen gas (N₂) into a form that organisms can use. Although nitrogen gas makes up around 78% of Earth's atmosphere, plants and animals ...
Medical Xpress / Continuous glucose monitors may reveal hidden heart risk patterns in adults without diabetes
Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are the clinical gold standards for screening blood sugar levels, yet they provide only static snapshots that fail to reflect the highly dynamic and heterogeneous nature ...
Medical Xpress / A blind retina isn't silent—and its noise may hinder efforts to restore sight
When retinitis pigmentosa takes a person's sight, the standard clinical test goes flat: no response, no signal, nothing. Yet the retina behind that flat line is anything but quiet.
Phys.org / Sixteen new fungus species found hiding in Thailand's flowers
Researchers have discovered 16 new species of fungus living unnoticed inside garden flowers and wildflowers across northern Thailand, more than quintupling the number of such fungi known to occur in the country. The findings ...
Phys.org / Global database reveals hidden diversity and potential of deep-sea microbes
The ocean's aphotic zone—the dark, high-pressure region below the surface, where sunlight cannot reach—is home to a vast wealth of microbial life. Yet scientists know relatively little about the genetic makeup, growth and ...
