Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building proteins begins to jam and ...

Using cannabis edibles and alcohol together may make drivers far more impaired than either substance alone, according to new research from Johns Hopkins. Even more concerning, common field sobriety tests often failed to detect the cannabis-related .. ...

A sweeping global study found that chronic kidney disease now affects nearly 800 million people and has become one of the world's leading causes of death. Often silent in its early stages, the condition is also a major contributor to heart disease .. ...

Feeling constantly drained might not just be about poor sleep or working too hard. Researchers in Japan found that low levels of key vitamins -- especially vitamin B12 and folate -- may quietly contribute to fatigue and lack of motivation, even in .. ...

For more than a century, pianists and music teachers have argued over whether a performer's touch can actually change the tone color of a piano note -- and now scientists say the answer is yes. Using a cutting-edge sensor system that tracked piano .. ...

A newly identified protein called GPNMB may play a major role in helping Parkinson's disease spread through the brain. Researchers discovered that immune cells release the protein in response to damaged neurons, creating a vicious cycle that speeds . ...

A new brain imaging study has found no evidence of widespread brain inflammation in patients suffering from prolonged symptoms after COVID-19 infection. Instead, the most severe long COVID symptoms were associated with increased brain activity in ...
