How did fingers appear during evolution? While it is established that they derive from genetic programs already present in fish, their precise origin remained debated. An international team led ...

Scientists have decoded the sea spider’s genome for the first time, revealing how its strangely shaped body—with organs in its legs and barely any abdomen—may be tied to a missing gene. The detailed ...

A novel technique that uses a simple cheek swab to detect gene mutations in healthy tissue could emerge as a "useful tool for cancer prevention", researchers have suggested. Experts anticipate that ...

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same ...
