Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That's the result of a new study we co-authored in the journal Scientific Reports.

Researchers at the University of São Paulo (USP) in Brazil discovered that neurodegenerative diseases, such as Alzheimer's, Parkinson's, and multiple sclerosis, are more complex than previously thought. Their analysis of ...

Your brain is currently expending about a fifth of your body's energy, and almost none of that is being used for what you're doing right now. Reading these words, feeling the weight of your body in a chair—all of this together ...

Adopted children who have grown up in more favorable family environments than their siblings are at lower risk of mental health issues, criminality and social problems, benefits that—in some cases—extend to the next generation. ...

Scientists at Memorial Sloan Kettering Cancer Center (MSK) and their colleagues are shedding new light on a tumor's earliest moments—revealing how lung cells with cancer-causing mutations recruit accomplices from healthy ...

Some 254 million people live with a chronic hepatitis B (HBV) infection that is often asymptomatic for decades, only to emerge in an advanced stage of disease that turns to fatal cirrhosis or liver cancer in nearly a million ...

For many years, a dominant view in neuroscience was that neurons in the inferotemporal (IT) cortex—a critical center in the brain for the recognition of objects—represent the world through fixed tuning functions. Doris Tsao ...

Every day, thousands of people worldwide suffer a heart attack, often leading to lasting damage to the heart muscle. Recent research from the University of Oslo suggests that targeting inflammation in the body helps protect ...

Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials published ...

Treatment with GMRx2, a single pill combination of three low-dose blood pressure medicines, significantly reduced the risk of another stroke in patients with intracerebral hemorrhage and high blood pressure. Results from ...

When probes are inserted into the brain for research or clinical purposes, the electrical activity of neurons is recorded. These signals can be used to understand how the brain performs certain computations or even to identify ...

Researchers from the University of Cape Town's (UCT) Scientific Computing Research Unit (SCRU) have uncovered a critical molecular "switch" that drives the formation of cancer-associated antigens. The study, published in ...
