Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and ...

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...

Scientists at City of Hope have uncovered a gene called SMOC1 that plays a surprising role in the development of type 2 diabetes (T2D) by converting pancreatic cells that normally produce insulin into ...

Aging does not arrive all at once. It builds quietly across years, touching cells long before symptoms appear.

Five years ago, Nobel laureate Carolyn Bertozzi, PhD, and her team described novel small RNA-glycan conjugates, glycosylated RNAs (glycoRNAs), on the cell surface. These small non-coding RNAs have ...
