A new single-nucleus atlas of mouse liver and skeletal muscle shows that individual cell types within these highly metabolic ...

By reprogramming red blood cell precursors into neural stem cells, researchers effectively reset the cell’s molecular clock.

A review in Biogerontology proposes evaluating molecular aging clocks as task-bound tools rather than by age-prediction error ...

Heavy polar molecules are some of the most sensitive tools physicists have for probing what lies beyond the Standard Model, the theory that describes the particles and forces we know about. But ...

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first ...

The Molecular Clock and Neutrality When the idea of a constant molecular clock first emerged, it was thought that the predominant evolutionary force underlying amino acid or nucleotide substitutions ...

In the brain, what matters is not only whether a signal reaches a nerve cell, but also how long its chemical gate remains open. A team led by Dr. Mehdi Borjkhani from the International Centre for ...

The brain is the most complex organ in the human body. Different parts of the brain perform a variety of functions, all of which are necessary for it to operate in one way or another. These functions ...

Learn how molecular rhythms inside maggots could help investigators refine the window for determining time of death. When a body is discovered, one of the first clues investigators turn to isn’t a ...
