Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have created one of the largest reference models ever developed for the human brain, ...
Medical Xpress / Engineered gut bacteria match fecal transplants in small C. difficile trial
Researchers at the Icahn School of Medicine at Mount Sinai have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based ...
Medical Xpress / Researchers say daylight saving time may worsen cognitive, psychological problems
Daylight saving time isn't just a seasonal inconvenience—it may also pose significant neuropsychological risks for the hundreds of millions of people worldwide who experience biannual clock shifts, especially those living ...
Medical Xpress / CRISPR model links faulty collagen to brain microbleeds tied to memory decline
Millions of older adults have tiny brain hemorrhages called cerebral microbleeds, which are strongly associated with dementia, cognitive decline, and stroke. However, their precise molecular mechanisms have remained unclear, ...
Medical Xpress / Ultrasound-based pacemaker noninvasively steadies the heart
MIT engineers have developed a noninvasive pacemaker that stimulates the heart using ultrasound. The design could one day provide a surgery-free alternative to traditional cardiac implants.
Medical Xpress / Nursing home staffing declined in states that protected facilities from COVID-19 malpractice lawsuits, study finds
Nursing homes across the country had less staffing in states where legislatures granted the facilities immunity from COVID-19-related lawsuits filed by patients and their families, according to findings from a new UCLA-led ...
Medical Xpress / Shrunken genomes may drive rapid cancer evolution and poor outcomes
Researchers at Trinity have found that a largely overlooked form of cancer evolution, which drives aggressive disease and poor patient outcomes, is far more widespread than previously thought. Comparing chromosome patterns ...
Medical Xpress / Copper imbalance tied to autism's social symptoms and white matter development
Trace elements are needed only in small amounts, but they can have large effects on the developing brain. A research team led by Niigata University has now reported that copper, an essential trace element, may help connect ...
Medical Xpress / The hum that only a few can perceive: Potential sources of a low-frequency sound
Some people occasionally hear a low buzzing or humming sound that doesn't have a clear source. An estimated 2–4% of the world's population hear this. Scientists have been trying to figure out for decades where this sound ...
Medical Xpress / Custom 4D-printed implants offer less painful path to tissue reconstruction
Tissue expansion is a common technique used in reconstructive surgery. Surgeons slowly stretch nearby skin to grow extra tissue that can be used to rebuild areas such as the ear, breast, or nose.
Medical Xpress / Drug duo synergy may help cystic fibrosis patients clear lung mucus, animal tests suggest
Two existing types of drugs synergize to improve the clearing of mucus from the lungs of animals with cystic fibrosis, a Stanford Medicine research team has found. The findings are published in the June 2026 issue of the ...
Medical Xpress / T cells may be key to stopping measles virus—and its deadly relatives
T cells are some of the immune system's most important warriors. They can stop tumor growth and even fight off severe infections. Now scientists at La Jolla Institute for Immunology (LJI) have discovered how T cells target ...
