Prions are extremely resilient, infectious proteins. Studying their shape-shifting abilities could reveal lessons for how proteins fold at a molecular level, helping scientists design better ones.

Serratia marcescens, a pathogen with an uncanny resemblance to blood, has had an outsized influence on modern science.

How genetics and IVF empowered a family to leave cancer behind.

Two physical constraints help explain why cells are so tiny: surface area-to-volume ratios and diffusion. The first article in our new Data Series.

A brief history of the repressilator, a genetic circuit that gave rise to synthetic biology.

A 2020 study suggests that monkeys can develop Parkinson’s, just like humans. Why haven't the findings been duplicated, and what will it take to find more “natural” animal models?
