How the body senses an essential amino acid

A new paper from Whitehead Institute researchers reveals how mice sense an essential amino acid called leucine, which many people get from eating fish, eggs, or nuts. Down the line, the work could inform research into creating ...

Scientists engineer synthetic DNA to study 'architect' genes

Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.

Study identifies distinct roles for nuclear lamin isoforms

A Northwestern Medicine study has uncovered distinct roles for major nuclear lamin isoforms in maintaining intracellular interactions and cellular mechanics, according to findings published in the Proceedings of the National ...

The secret to a longer lifespan? Gene regulation holds a clue

Natural selection has produced mammals that age at dramatically different rates. Take, for example, naked mole rats and mice; the former can live up to 41 years, nearly ten times as long as similar-size rodents such as mice.

How cells correct errors under time pressure

How does a cell balance risk and speed when dividing? EPFL scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently.
