Genetic testing can reveal secrets — sometimes surprising and sometimes predictable — about a person's origins.

Scientists in the United States have pointed the finger at seven genes that appear to play a role in psoriasis, a study published on Sunday says.

DNA taken from the hair of two extinct Tasmanian “tigers” suggests the Australian marsupials last seen 70 years ago may have become too inbred to survive as a species, researchers reported on Monday.

Scientists say they have pinned down a DNA mechanism that gives rise to a rare but distressing form of baldness that strikes before adulthood.

U.S. scientists have created the first human model for studying a devastating nerve disease, which allows them to watch how the disease develops and could help researchers find a way to treat it.

Biologists at Academia Sinica have spotted “speciation” genes in budding yeasts and have observed for the first time the mechanisms related to these genes, according to a paper published in Dec. 12 issue of the peer-reviewed journal Cell.
