Scientists discover a 'mortality timer' in cells, revealing new insights into aging and potential ways to extend lifespan.

Like Bill Murray in the movie "Groundhog Day," bacteria species in a Wisconsin lake are in a kind of endless loop that they can't seem to shake. Except in this case, it's more like Groundhog Year.

Imagine you're a scientist, tasked with the challenge of rapidly producing large quantities of high-quality messenger RNA (mRNA) for use in cutting-edge medical treatments. Where do you even start?

A new study has identified one of the reasons why cancer frequently spreads from elsewhere in the body to the lungs: an amino ...

Smaller nucleoli slow aging, acting as a "mortality timer," while larger nucleoli lead to cell death by destabilizing rDNA. The secret to cellular youth may lie in maintaining a small nucleolus—a ...

Dec. 16, 2024 — Researchers have uncovered unexpected diversity in the genetic processes that determine the sex of the African clawed frog, a significant discovery in what was already one of the ...

DNA from bones and teeth of these early human ancestors is helping scientists understand the interactions between early Homo sapiens and the Neanderthals they encountered after migrating out of Africa ...

Formyl-methionyl-tRNA is bound to ribosomes by single stranded circular DNA of the phage fd. Addition of neomycin B to this complex permits direct translation of this DNA into protein, which ...

Scientists say they have recovered the oldest known Homo sapiens DNA from human remains found in Europe, and the information is helping to reveal our species’ shared history with Neanderthals.
