Medical Xpress / 3D-printed brain sensors may unlock personalized neural monitoring
Soft electrodes designed to perfectly match a person's brain surface may help advance neural interfaces for neurodegenerative disease monitoring and treatment, according to a new study led by Penn State researchers. Neural ...
Medical Xpress / How mRNA cancer vaccines still destroy tumors when a key immune cell is missing
The advent of mRNA vaccines against SARS-CoV-2 in 2020 changed the course of the COVID-19 pandemic. Now, the Nobel Prize–winning technology is being adapted to fight cancer, with mRNA vaccines in clinical trials for melanoma, ...
Medical Xpress / Sex differences in brain gene activity could explain why some disorders affect men and women differently
The physical differences between men and women are all too obvious, but the biological divide goes right down to the cellular level in the brain, according to a new study published in the journal Science.
Medical Xpress / Brain-on-a-chip reveals how Parkinson's proteins weaken the brain's vascular barrier
Scientists looking for the causes of neurodegenerative diseases like Parkinson's and Alzheimer's generally focus on the buildup of aberrant proteins in the brain that impede normal neural connections. But new research from ...
Medical Xpress / Why private gardens mattered so much during the first COVID-19 lockdown
A team of researchers led by the University of Aberdeen has found that private gardens played a vital role in supporting people's well-being during the U.K.'s first COVID-19 lockdown, when access to public green spaces was ...
Medical Xpress / How a tiny circle of repeat offenders poisoned 100s of gold-standard medical trials for over a decade
Randomized Controlled Trials (RCTs) are the gold standard of medical research as random assignment approach helps eliminate bias and yields the most reliable evidence on whether a treatment truly works. Since RCTs sit at ...
Medical Xpress / Real-world MRI data confirm shared brain signatures of mental health disorders
Over 1 billion people worldwide are living with one or more mental health disorders that affect their mood, thinking processes and behavior, impacting their daily functioning to varying degrees. Identifying variations in ...
Medical Xpress / Cutting calories to slow aging—without compromising health
Restricting calorie intake in species such as mice, rhesus monkeys, and fruit flies has been shown to extend their lifespans. In some cases, these animals not only live longer, but are also free of disease. But when pushed ...
Medical Xpress / Blood pressure drug effective for treating antibiotic-resistant bacteria, study finds
Infections from antibiotic-resistant bacteria are difficult to treat and are responsible for over 2.8 million infections and more than 35,000 deaths in the U.S. each year. A new study in Nature Communications reports that ...
Medical Xpress / Growing liver tissue directly in the body could ease donor organ shortage
In patients developing end-stage liver disease, the damage has become too severe for the liver's normally extraordinary regenerative capacity to repair or compensate for it. Once this "point of no return" has been reached, ...
Medical Xpress / Why discarded brain 'noise' matters: Overlooked networks may reshape mental health treatment
Scientists who use imaging to understand the brain's complexity often focus on the strongest signals and ignore the rest. But this strategy, researchers warn, may reveal only the tip of the iceberg. A study published in Nature ...
Medical Xpress / Songbird brains can generate new neurons: Can human brains do the same?
Despite its small size—it could sit in the palm of your hand—the zebra finch is a remarkable learner. A songbird native to Australia, it's renowned for its ability to pick up new songs. That talent has made it a favorite ...
