Medical Xpress / Can you spot an AI face? A new test shows why some people do better
Can you tell the difference between an artificial-intelligence-generated face and a real one? In an era of digital misinformation, where fabricated images can spread widely across news and social media, this skill is proving ...
Medical Xpress / Senescent astrocytes discovered in Alzheimer's brains point to new treatment targets
Researchers from the NeuroAD group (Neuropathology of Alzheimer's Disease) within the Department of Cell Biology, Genetics and Physiology at the University of Málaga, also affiliated with IBIMA–BIONAND Platform and CIBERNED, ...
Medical Xpress / Alzheimer's gene boosts seizures, but pathway can be targeted, study finds
The gene most strongly correlated with Alzheimer's disease also boosts seizure activity by decreasing levels of ion pumps and energy-producing enzymes in neurons, a new study by researchers at the University of Illinois Urbana-Champaign ...
Medical Xpress / Studies show 11 genetic variants affect gut microbiome
In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic ...
Medical Xpress / Sensing local fibers in pancreatic tumors, cancer cells 'choose' to either grow or tolerate treatment
A feature of pancreatic cancer cells' surroundings determines whether they grow fast or become resistant to chemotherapy, a new study shows. The ability of these cancer cells to adapt quickly and toggle between biological ...
Medical Xpress / Cancer virus imaging helps uncover potential therapeutic targets
New research from the University of Minnesota School of Dentistry and Masonic Cancer Center is providing important new insights into the structure of a human virus that causes blood cancer. In their study published in Nature ...
Medical Xpress / AI model flags insulin resistance as a risk factor for 12 cancers
Insulin resistance—when the body doesn't properly respond to insulin, a hormone that helps control blood glucose levels—is one of the fundamental causes of diabetes. In addition to diabetes, it is widely known that insulin ...
Medical Xpress / Dual brakes on T-cells: New targets found to boost immunity in chronic infections
Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve treatments to control chronic ...
Medical Xpress / Ketamine's 'mystical' effects fail to explain alcohol abstinence gains, study suggests
The psychedelic effects recreational users often seek from taking ketamine do not predict the therapeutic benefits for people being treated for alcohol use disorder. The popular theory, which says that ketamine may have its ...
Medical Xpress / How bacteria may promote breast cancer
Researchers at the Johns Hopkins Kimmel Cancer Center have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known ...
Medical Xpress / Optimizing CAR T-cell therapy to tackle solid tumors
In 2024, Professor Sebastian Kobold's research group at LMU University Hospital had already shown that the metabolite prostaglandin E2 can block T cells—the killer cells of the immune system—in the vicinity of a tumor, ...
Medical Xpress / Mouse study reveals local antibody 'brakes' shape B cell selection
A collaborative study published in Immunity from the Batista Lab and Liu Lab at the Ragon Institute, together with the Schief Lab at Scripps Research Institute, has uncovered a previously unrecognized mechanism that shapes ...
