Infertility affects more than 15% of couples worldwide. Thanks to medical science, infertility treatments have come a long way over the past few years. For millions of people, in vitro fertilization (IVF) has opened a medical ...
Medical Xpress / Scientists identify gene signatures in children with severe COVID-19 infection
Researchers have identified patterns of gene activity associated with severe COVID-19 in children that are shared with other serious respiratory infections.
Medical Xpress / Fruit fly study reveals how neural gates switch on short-term memory
A study in fruit flies led by researchers at NYU Langone Health has confirmed a long-standing suspicion about how the brain encodes short-term memories.
Medical Xpress / Health records link ADHD to more than fourfold higher risk of later cognitive impairment
A new study led by University of Pittsburgh School of Medicine researchers finds that adults with attention-deficit/hyperactivity disorder (ADHD) face a significantly higher risk of developing dementia or mild cognitive impairment ...
Medical Xpress / How your brain keeps learning while you rest
When you're stuck on a tough problem, it's not uncommon to take a walk or give your brain a break, only to gain that sudden flash of inspiration or insight you were looking for.
Medical Xpress / Human lung organoids with a built-in immune system could transform respiratory disease research
A new organoid model built with human lung fragments may help us answer key questions about one of the body's first lines of defense against respiratory pathogens. In a new study, researchers at the Stanford University School ...
