A strain of bacteria that lives in the stomach could help protect against a common type of esophageal cancer.

H. Pylori bacteria is a known cause of stomach cancer and ulcers -- but has become less common over the years because of advances in sanitation.

Now doctors are seeing a rise in adenocarcinoma, a type of esophageal cancer.

Researchers at the national cancer institute found people with h. Pylori strains that carry a certain gene were almost half as likely to get adenocarcinoma as people without it.

Researchers have developed a vaccine that may be able to preserve some of the insulin-producing cells affected in type one diabetes patients.

Researchers in Sweden studied 70 patients under the age of 18 who had been recently diagnosed with Type I diabetes.

Half received two doses of a vaccine that targets proteins that preserve insulin-producing cells.

They found the vaccine did not lower the amount of insulin patients needed everyday, however it did help the body maintain its ability to secrete its own insulin.

While this is a step in the right direction, researchers say many more studies are needed.

Studies in mice showed the vaccine could prevent the disease in those at high risk.
