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.

Scientists in Tanzania turned an iPhone into an amateur microscope to check schoolchildren for intestinal worms.

A baby born with the AIDS virus appears to have been cured, scientists announced Sunday, describing the case of a child from Mississippi who's now 2 1/2 and has been off medication for about a year with no signs of infection....

Flying increases flatulence, according to an article published Friday in the peer-reviewed New Zealand Medical Journal, and passengers should release the gas -- or risk painful medical consequences.

The work is a first step toward one day growing customized new ears. Scientists at Cornell have put 3-D printing to an incredible medical use: They've made an ear remarkably similar to a natural one. Using 3-D images of a human ear, they printed a mold to be injected with gel containing collagen from rats' tails, HealthDay reports. Next, they added cartilage from cows' ears.

Scientists reported Thursday that they succeeded in creating tiny medical devices sealed in silk cocoons that did the work they were designed for, then dissolved in the bodies of lab mice. It's an early step in a technology that may hold promise not only for medicine but also for disposal of electronic waste.

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.

For the first time doctors have successfully transplanted a vein grown with a patient's own stem cells, another example of scientists producing human body parts in the lab. In this case, the patient was a 10-year-old girl in Sweden who was suffering from a severe vein blockage to her liver. Last March, the girl's doctors decided to make her a new blood vessel to bypass the blocked vein instead of using one of her own or considering a liver transplant.

In just three weeks, gamers deciphered the structure of a key protein in the development of AIDS that has stumped scientists for years.

Mayo Clinic researchers have developed a genome-based immunization strategy to fight feline AIDS and illuminate ways to combat human HIV/AIDS and other diseases. The goal is to create cats with intrinsic immunity to the feline AIDS virus.
