Medical Xpress / Lab-grown brain-spinal cord model shows 'irreversible' nerve damage may be reversed
Cambridge scientists have grown miniature circuits in the lab that mimic how the brain and spinal cord connect, which underlies human movement. They used this model to show how damage to these connections previously considered ...
Medical Xpress / Blood biomarkers reveal subtle midlife cognitive decline tied to Alzheimer's risk
For the first time, researchers found blood biomarkers for Alzheimer's disease that correlated with minor cognitive differences in midlife adults who did not have dementia. The study, led by UC San Francisco, also found that ...
Medical Xpress / Lab-grown heart patch boosts pumping power in severe heart failure trial
Researchers at the University Medical Center Göttingen (UMG) and the University Hospital of Schleswig-Holstein (UKSH) have made a significant breakthrough in the treatment of severe heart failure: For the first time, a clinical ...
Medical Xpress / AI suggests simple food swaps to make meals healthier and cheaper
An artificial intelligence framework that suggests just one to three ingredient swaps can make meals meaningfully more nutritious and less expensive, according to a new study published in PLOS Digital Health by Trevor Chan ...
Medical Xpress / New brain scan detects Alzheimer's tau earlier than current standard
A new brain imaging test can detect a key hallmark of Alzheimer's disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh ...
Medical Xpress / Scientists validate a link between autoimmunity and long COVID
A Mount Sinai-led research team has demonstrated that autoimmunity, in which the body's immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of ...
Medical Xpress / Rare DNA variants reveal new metabolic links in one of the largest analyses yet
Led by University of Tartu researchers, the largest and most comprehensive study to date has been completed on how genetic differences between individuals influence metabolism. Published in Nature, the study provides a far ...
Medical Xpress / Rising heat could triple heart disease burden in U.S. by 2050
A new study by researchers at Case Western Reserve University, University Hospitals and the Louis Stokes Cleveland VA Medical Center predicts rising temperatures driven by climate change will dramatically increase heat-related ...
Medical Xpress / Brain maps reveal first lifetime white matter growth charts from birth to 100
In a new study published recently in the journal Nature, researchers at Vanderbilt University and Vanderbilt Health have created the first growth charts for white matter in the brain over a human lifetime. The work brings ...
Medical Xpress / Young adults are more perfectionistic than ever before, study finds
College students feel more pressure to be perfect than they did a generation ago, finds research published in Psychological Bulletin. That increase in perfectionism may be tied to social and economic factors such as rising ...
Medical Xpress / 'Toxic' molecule may play vital role in gene regulation and development
A molecule once thought to be a harmful metabolic byproduct may play a crucial role in early development and gene regulation, according to a new study published in Nature that challenges decades of biochemical assumptions. ...
Medical Xpress / Immune 'energy signature' linked to tuberculosis may explain why some individuals control infection
Researchers at Trinity College Dublin have identified key differences in how immune cells generate and use energy, a process known as cellular metabolism, in people with latent versus active tuberculosis (TB). The findings ...
