Medical Xpress / New model maps where HIV is concentrated and the disease is more advanced
A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. ...
Medical Xpress / AI companions may worsen loneliness for vulnerable users
AI companions are becoming increasingly popular, with millions of users forming deep connections with persona-based chatbots and simulated AI partners. But if you're considering leaning on an AI companion for emotional support, ...
Phys.org / Marine microbes point to ancient seawater source beneath Antarctica's Blood Falls
Salty water flowing through Antarctica's Blood Falls contains a distinct community of marine-specific microorganisms, providing evidence that the brine system beneath the glacier has a marine origin, according to a paper ...
Medical Xpress / US sees a big jump in nausea cases among frequent marijuana users in the hospital
In the past year, the U.S. has seen a jump in frequent marijuana users going to the hospital with a nausea and vomiting condition, according to a report released Thursday.
Phys.org / Quantum computer completes verified task beyond practical reach of classical simulations
IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for "quantum advantage"—the point where quantum computers can be confirmed to have outperformed ...
Phys.org / Avalanche cracks may appear globally supersonic while remaining locally subsonic
Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific ...
Phys.org / New molecule class creates hardy, drought tolerant plants
As climate change causes water scarcity and temperatures to rise, crops around the world are feeling the heat. How can we prevent severe crop losses in these relentlessly sweltering conditions? An international research team ...
Medical Xpress / Gene mutations behind serious bone marrow conditions identified
Inherited bone marrow failure syndrome, or IBMFS, describes a group of disorders in which inherited genetic abnormalities impair the bone marrow's ability to produce sufficient healthy blood cells. Patients with these disorders ...
Phys.org / Decades-old theory for how insect societies evolve challenged
For more than 60 years, evolutionary biologists have debated whether a unique genetic system found in ants, bees and wasps helps explain one of nature's most remarkable innovations: eusociality, a form of social organization ...
Medical Xpress / IL-1 pathway may stop Candida fungus from turning fatal in weakened immunity
An immune pathway has been discovered that prevents a normally harmless fungus from developing into a fatal infection. The King's College London study, published in Nature Microbiology, provides the first potential clue as ...
Phys.org / Nano-optics: New mechanism for channeling light waves discovered in natural hyperbolic materials
Researchers at the 4th Physics Institute of the University of Stuttgart and the Istituto Italiano di Tecnologia (IIT) in Milan have demonstrated a new mechanism for directing light in a naturally hyperbolic van der Waals ...
Medical Xpress / Nearly 1 in 100 Canadians has inflammatory bowel disease. Too many believe it rules out having children
I often reflect on the advice of an outdated article on inflammatory bowel disease (IBD) and pregnancy from 1956. It stated: "There should be no doubt that a woman with ulcerative colitis who wishes to have a child should ...
