Major academic medical centers in New York and around the country are spending and recruiting heavily in what has become an arms race within the war on cancer. The investments are based on the belief that the medical establishment is moving toward the routine sequencing of every patient’s genome in the quest for “precision medicine,” a course for prevention and treatment based on the special, even unique characteristics of the patient’s genes.

The Supreme Court will soon decide whether companies can patent human genes, a decision that could reshape the future of medical care in the United States.

Scientists have found a master regulator gene needed for the development of M cells, a mysterious type of intestinal cell involved in initiating immune responses.

Scientists have discovered two gene variants that appear to play a critical role in the development of common childhood obesity, according to a large genetic study released Sunday. The discovery could eventually lead to treatments and specific lifestyle advice for heavy children.

A gene that can turn many types of bacteria into deadly superbugs was found in about a quarter of water samples taken from drinking supplies and puddles on the streets of New Delhi, according to a new study....

MIT scientists have created a sort of genomic fossil that shows that the collective genome of all life underwent an enormous expansion about 3 billion years ago, which they're calling the Archean Expansion. Many of the new genes appearing in the Archean Expansion are oxygen related, and could be the first biological evidence of the Great Oxidation Event, the period in Earth's history when oxygen became so plentiful that many anerobic life forms may have become extinct.

At least 30 genes appear to play a role in the age at which girls reach puberty, according to an international group of scientists.

Research by University of Leeds plant scientists has uncovered a snapshot of evolution in progress, by tracing how a gene mutation over 100 million years ago led flowers to make male and female parts in different ways.

Gene therapy has been used to correct an inherited blood disorder in what doctors say is a major step forward in treatment.

Mutations have been found to extend the lifespan of animals in the lab such as worms, fruit flies and mice, and appear to play the same role in humans. Professor Linda Partridge, director of the Institute of Healthy Ageing at University College London, said such research could help treat or delay many diseases simultaneously with medication.
