Immune cells are the elite athletes of the human body. While other cells stay in place, immune cells travel throughout our bodies, squeezing through small channels, stretching themselves, sampling the surfaces of other cells and swallowing up invaders. One of their most extreme behaviors is NETosis, a process in which certain immune cells burst and release their DNA as a way to trap pathogens.

Just 7 days of strength training started shrinking fat cells in mice

Just seven strength-training sessions helped obese mice shrink visceral fat cells and reactivate molecular pathways involved in burning stored fat, despite no change in overall body weight. The findings suggest some benefits of resistance exercise may begin long before weight los

Scientists discover a human brain gene that can jump through DNA

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans

Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn thro
