Scientists accidentally discovered a microscopic organism with a genetic code that breaks a rule researchers thought was nearly universal. While testing a new DNA sequencing technique, they examined a previously unknown protist collected from a freshwater pond at Oxford University. To their surprise, the organism uses two genetic signals that normally mark the end of a gene to encode two entirely different amino acids instead.

These signals were previously thought to evolve together, making the discovery particularly remarkable.

Changes in DNA packaging help immune cells swell and burst

Immune cells are the elite athletes of the human body. While other cells stay in place, immune cells travel throughout our bodies, squeezing through small channels, stretching themselves, sampling the surfaces of other cells and swallowing up invaders. One of their most extreme b
