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.

Scientists discover a human brain gene that can jump through DNA
Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans
