The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Late in 2025, we covered the development of an AI system called Evo that was trained on massive numbers of bacterial genomes. So many that, when prompted with sequences from a cluster of related genes ...

The DNA foundation model Evo 2, first released in February 2025 as a preprint, is now published in the journal Nature . Trained on the DNA of over ...

The DNA foundation model Evo 2 has been published in the journal Nature. Trained on the DNA of over 100,000 species across ...

Hardy bacteria in a lab survived pressures comparable to an asteroid strike on the red planet, suggesting a hypothetical scenario in which our planet was seeded with life.

Researchers at Vilnius University’s Life Sciences Center (VU LSC) have discovered a surprising new function for Cas9, the famed CRISPR-Cas ‘gene scissors’, showing it plays a key role in ...

According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...

The majority of DNA in one’s body does not encode for any protein. In a Feb. 25 lecture, Rachel Mueller, Colorado State University biology professor, addressed questions surrounding junk DNA, ...

As metals fuse and sparks fly, one researcher’s work takes the form of DNA, a bacteriophage, a nucleosome, and more.

Researchers have identified a promising way to predict bloodstream infections in children with high-risk leukemia days before the infection would be diagnosed using current standards of care. The test ...
