In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating ...

Whether they are competing approaches or complementary, there are good ways to incorporate both these AI-based methods into developing resilient applications. Vibe coding and spec-driven development ...

A graphic of a purple and magenta Cas9 protein, which is a somewhat round, but uneven, ball, bound to a yellow and orange strand of DNA, which is a long, thin spiral that is vertical to the protein.

Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence ...

New research has discovered that the molecular machines responsible for copying our DNA have a surprising hidden talent: an ability to create entirely new and highly sophisticated DNA sequences from ...

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 ...

Megan covers the intersection of science and society. How is biomedical research funded? Who benefits? And how do new technologies reflect and shape our values? You can reach Megan on Signal at ...

A blue-and-gray 3D representation of a strand of DNA with other strands floating in the background. Google has officially released its AlphaGenome machine learning model, which can predict the ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
