Medical Xpress / Experts highlight limits of evidence from ultraprocessed food trials
A group of eating behavior and metabolism experts from across Europe have published a Perspective article in the journal Science examining the limitations of current evidence on ultraprocessed foods (UPFs).
Medical Xpress / Long-hidden 'junk DNA' regions may help explain cancer-linked genome instability
Many repetitive regions of the genome have been considered "junk DNA" because the available technologies did not allow them to be studied at sufficient resolution. This is the case for the SST1/NBL2 macrosatellites, considered ...
Medical Xpress / New hantavirus sequencing tool maps whole genomes from hard-to-test samples
Infections by hantaviruses are rare but dangerous, killing 30–40% of infected people. When cases occur, public health officials need rapid, detailed information about the virus to identify the strain and its origin, so they ...
Medical Xpress / Smartphone unlock can measure heart rate, potentially bringing health monitoring to billions worldwide
Wearable devices like smartwatches and fitness trackers have revolutionized the way we monitor our health. Worn around the clock, these devices quietly collect valuable data—from heart rate and blood oxygen levels to sleep ...
Medical Xpress / The brain can unlock true multitasking after intensive training
New research by Georgetown scientists shows how the brain rewires itself to automate learned tasks. The findings challenge a long-held understanding of how humans master complex skills, suggesting that true multitasking is ...
Medical Xpress / Topical gel helps burn wounds heal faster using an existing FDA-approved drug
Researchers at the Terasaki Institute for Biomedical Innovation and the University of Arizona College of Medicine have developed a topical gel formulation with 4-aminopyridine (4-AP), to treat burn wounds, achieving near-complete ...
Medical Xpress / Blood test spots 14 proteins that predict lung cancer risk up to five years early
As we age, our cells acquire cancer-causing mutations, but mutations alone are rarely enough to start a tumor. An environmental trigger, such as exposure to air pollution from sources such as combustion engines, coal burning ...
Medical Xpress / Brain circuit that times a state of low metabolism could have implications for space travel
You have gone without food for days, and the temperature drops to near freezing. What do you do? For some animals, the answer is influenced by the brain's circadian clock. Hummingbirds, bats, and mice are among the animals ...
Medical Xpress / Even years after stroke, spinal cord stimulation could improve arm function
University of Pittsburgh School of Medicine researchers report the final outcomes of a pioneering pilot clinical trial using electrical stimulation of the spinal cord to improve arm and hand mobility in people with chronic ...
Medical Xpress / Autism risk framework tracks genes, maternal factors and environment across 18,000 families
A new statistical framework developed by researchers at the Johns Hopkins Bloomberg School of Public Health, Johns Hopkins University School of Medicine, and Kaiser Permanente Northern California offers improved understanding ...
Medical Xpress / Alzheimer's tipping point revealed as brain immune cells hit a key transition
Researchers from VIB, KU Leuven, the UK-DRI and Muna Therapeutics have uncovered a critical biological transition that may determine whether Alzheimer's disease pathology leads to dementia. Studying brain tissue from older ...
Medical Xpress / Newfound 'switchboard' helps brain form new memories without forgetting older ones
The brain may reuse some cells to store many different memories without mixing them up with or erasing older memories, a new study in mice suggests. Led by NYU Langone Health researchers, the study revealed that about 1 in ...
