Mitochondrial DNA replacement successful in Rhesus monkeys
New procedure may halt some serious inherited diseases, a study suggests.

Protein plays three cancer-fighting roles
The tumor suppressor protein, p53, has three ways to protect cells from turning cancerous. A new study shows that p53 helps make microRNAs.

Old gene, short new trick
A single genetic modification is linked to the stature of short-legged dog breeds, new research shows.

Schizophrenia risk gets more complex
Three studies find that large collections of variants, rather than just a few key mutations, probably predispose someone to schizophrenia.

Engraved pigments point to ancient symbolic tradition
Analyses of patterns incised on pieces of ancient pigment indicate that people in southern Africa passed along symbolic practices from 100,000 to 75,000 years ago, scientists say.

Four marmosets are first transgenic primates
Scientists in Japan have successfully introduced a foreign gene into a primate species for the first time, opening a new avenue for modeling human diseases, particularly brain disorders.

Genetic analysis of swine flu virus reveals diverse parts
Detailed genetic analysis of the H1N1 swine flu virus indicates that its components have been present for years. The virus is still susceptible to drugs and vaccine development.

I was intrigued by the fact that some apoptotic cells can recover if not engulfed by another cell. DNA reassembly after the caspases tear it apart should result in many gene mutations. While most of the mutations would result in cell death, perhaps a few cells would have mutations that promote a cancerous or precancerous […]

Space trek may help worms live long
After 11 days in orbit, nematodes showed signs of slower aging.

Second of two blocked flu papers released
Held back for months by a U.S. government biosafety board, the research pinpoints five mutations that render the potent H5N1 virus transmissible through air.
