Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Scientists have mapped how genetics and life experiences leave lasting epigenetic marks on immune cells. The discovery helps ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research published in the Biophysical Journal shows that ...

Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. " We know each of the proteins ...

Since each cell has about six feet of DNA packed inside it, it must be folded up tightly to fit. This folding not only saves space -- it also controls which genes are active or inactive. But when the ...

Short-term IF boosts glucose homeostasis, but prolonged fasting in adolescence may impair β cell maturation—potentially linking chronic IF to type 1 diabetes risk. Study: Chronic intermittent fasting ...

Researchers discover how much inner-ear damage it takes to affect balance, showing why small declines can trigger major symptoms.
