Medical Xpress / Strong genetic mutation overrides female protective effects in autism, researchers discover
Autism spectrum disorder affects males far more frequently than females, with diagnoses occurring roughly four times more often in boys. Scientists have long suspected that females may possess biological protective mechanisms ...
Medical Xpress / How medical education can revive the physician–scientist pipeline
The physician–scientist has long occupied a unique place in medicine—bridging the laboratory and the clinic, translating scientific discoveries into innovative patient care. But that role is becoming increasingly rare. The ...
Medical Xpress / Brain's chemical brake hides a second power, and it could reshape how mental disorders are treated
An important chemical messenger that typically inhibits brain activity might sometimes do the opposite, according to new Yale School of Medicine (YSM) research. One way that brain cells communicate is through chemical messengers ...
Medical Xpress / Modern medicine cut gut microbial diversity in remote Amazonian communities after just a few visits, study shows
Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study appearing in Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities have begun shifting ...
Medical Xpress / Cytokine-armored CAR-T cell therapy helps eliminate aggressive brain tumors in preclinical study
Scientists at the UCLA Health Jonsson Comprehensive Cancer Center have developed a new cytokine-armored CAR-T cell therapy that helps the immune system better attack aggressive brain tumors in mice while reducing dangerous ...
Medical Xpress / How dead tumor cells could make chemotherapy and radiotherapy work better
As tumors outgrow their blood and nutrient supplies, or respond to treatments like chemotherapy and radiotherapy, individual cancer cells die, exposing their internal scaffolds. These dead cells are an abundant source of ...
Medical Xpress / Researchers identify new drug targets for hard-to-treat cancers
Despite impressive innovations in medicine, most advanced-stage cancers still carry a grim prognosis. Developing more effective treatments requires a deeper understanding of the cellular processes that drive the formation ...
Medical Xpress / Handwriting speed may be a sign of cognitive decline in older people
Handwriting requires a combination of fine motor control and a complex set of mental skills, such as selecting, organizing, and interpreting sensory information, making it a cognitively challenging task. Because of its high ...
Medical Xpress / Scientists make surprising discovery and find a possible new ally in the opioid crisis
Scientists at Bowling Green State University recently made a series of discoveries that could have wide-ranging implications for the future of the national opioid crisis. Through a partnership with the Toledo Lucas County ...
Medical Xpress / Spatial transcriptomics guides inflammatory bowel disease research
A novel spatial transcriptomics atlas developed by Northwestern Medicine scientists may improve the understanding of niche cellular interactions in the gastrointestinal tract that promote the development of inflammatory bowel ...
Medical Xpress / Hospital wastewater reveals drug-resistant fungus strains months before patients show symptoms
A new UNLV-led wastewater surveillance study brings scientists one step closer in the global race to detect and deter skyrocketing cases of a potentially deadly drug-resistant fungus that puts hospital patients at risk of ...
Medical Xpress / New clarity on a little‑understood stage of childhood development
Adrenarche—an early, puzzling transition between childhood and adolescence—has long been clouded by inconsistent terminology across pediatrics, endocrinology, and puberty research. A new call for precision aims to change ...
