Medical Xpress / Light-triggered arrhythmia reveals rapid brain oxygen shifts in mice
An irregular heartbeat, or arrhythmia, leads to inefficient pumping of blood by the heart, which then prevents blood and oxygen from getting to the body's other organs. When blood and oxygen flow poorly to the brain, the ...
Medical Xpress / Low-dose aspirin may offset premature birth risk linked to extreme heat
Mounting evidence links extreme heat to preterm (often called premature) birth, low birth weight, and stillbirth, indicating that rising temperatures are contributing to worse health outcomes for pregnant people and newborns. ...
Medical Xpress / Early immunotherapy aids in treating potentially fatal fungal pneumonias in preclinical models
A new study led by researchers at The University of Texas MD Anderson Cancer Center has shown that early administration of immunotherapy with standard antifungal treatment improved outcomes and largely alleviated immune system ...
Medical Xpress / Struggle sleeping? These three common sleep habits are tied to signs of brain aging
How we sleep may have lasting impacts on our brain health as we age. A new University of Arizona study has found that several common sleep behaviors may be linked to signs of brain aging.
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 / 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 / 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 ...
