Medical Xpress / Prenatal Zika exposure may trigger vision, hearing and social changes despite seemingly healthy births
Infants exposed to the Zika virus during pregnancy may face hidden developmental challenges, even if they appear healthy at birth. A recent study at the University of Wisconsin-Madison highlights the need for better developmental ...
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 / 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 / New drug cuts relapse risk by half in rare immune disorder trial
Stanford Medicine researchers and their colleagues found that a new drug, obexelimab, significantly reduces the risk of relapse in patients with IgG4-related disease, a rare chronic immune condition often misdiagnosed as ...
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 / Brain circuit links memory to hearing, revealing how learned sounds guide behavior
Short-term memories are thought to be formed deep within the brain in structures such as the hippocampus, but little is known about how and where memory-related information is kept in the brain or the process of drawing on ...
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 / Alzheimer's gene map expands to 91 loci, revealing 16 previously unknown risk regions
An international collaboration of genetic researchers has identified more than 90 genetic regions associated with the risk of Alzheimer's disease and related dementias. The large-scale meta-analysis reveals new biological ...
Medical Xpress / Immune barrier may explain why mRNA shots struggle to block nasal infection
A consistent biological barrier that stops the immune system from making the antibodies most needed to protect the nose and throat from respiratory viruses has been identified. The discovery, led by researchers from the University ...
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 ...
Medical Xpress / How cells fight infection from the inside: Newly identified ADX pathway may broaden understanding of immunity
When thinking of the immune system, most people imagine white blood cells putting up a fight against invading germs in the bloodstream. But now, in research published in Molecular Cell, scientists detail a separate but equally ...
Medical Xpress / Motherhood leaves lifelong brain marks via dopamine-linked epigenetic switch, mouse study suggests
Becoming a mother changes the brain not just temporarily, but for life. Pregnancy and the postpartum period trigger lasting changes in the maternal brain through the brain chemical dopamine, producing long-term benefits to ...
