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

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 ...

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 gene, when turned on, is transcribed into messenger RNA. These molecules shuttle genetic information from DNA to the cell’s protein-making factory, called the ribosome. Picture it as a sliced bun, ...

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

With so many at-home DNA tests now available to consumers, learning more about your ancestry is easier than ever. Plus, these tests make for thoughtful, unique holiday gifts. All you have to do is ...

The study centers around the ribosome, the protein factories of a cell. For decades, ribosomes were thought to have the same blueprint across the human body. However, researchers discovered a hidd ...

Jan. 1, 2025 — Researchers have traced a cellular route Ebola virus (EBOV) uses to traverse the inner and outer layers of skin and emerge onto the skin's surface. The study identifies new cell ...

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 ...

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.
