Scientists discover ancient brain cells that help block distractions
Scientists have identified a group of neurons located in an ancient region of the brain that plays a key role in helping animals focus. These cells appear to improve attention…
Scientists discover a hidden cause of aging cells that can be reversed
As people grow older, their cells gradually become less efficient at producing energy and responding to changing demands. Scientists have long known that mitochondria, often called the cell’s powerhouses, play…
Scientists supercharge natural killer cells to fight aggressive cancers
Scientists have developed a new way to strengthen the cancer-fighting abilities of natural killer (NK) cells, a type of immune cell that serves as one of the body’s first defenses…
“Zombie cells” aren’t always bad and that could transform anti-aging medicine
Aging research is entering a new phase as scientists rethink one of the body’s most mysterious cell types: senescent cells, often nicknamed “zombie cells.” While these aging cells have long…
Scientists discover vitamin B2 may help cancer cells survive
Vitamin B2 is essential for human health, but new research suggests it may also help cancer cells stay alive. Also known as riboflavin, vitamin B2 cannot be produced by the…
Scientists reverse diabetes in mice with lab-grown insulin cells
Scientists in Sweden have developed a more reliable way to create insulin-producing cells from human stem cells, bringing new momentum to efforts to treat type 1 diabetes. The research, published…
For the first time, scientists pinpoint the brain cells behind depression
Researchers at McGill University and the Douglas Institute have discovered that two distinct types of brain cells function differently in people with depression. The findings, published in Nature Genetics, offer…
Scientists remove “zombie” cells and reverse liver damage in mice
UCLA scientists have uncovered a harmful group of immune cells that quietly builds up in aging tissues and in the livers of people with fatty liver disease. When these cells…
Solar cells just did the “impossible” with this 130% breakthrough
Solar power plays a major role in efforts to reduce dependence on fossil fuels and address climate change. The Sun delivers an immense amount of energy to Earth every moment,…
Depression may start with an energy problem in brain cells
Researchers may have identified a promising new approach to diagnosing and treating major depression at its earliest stage, potentially improving the chances of recovery for many patients. Scientists at the…
