Scientists have uncovered new genes, pathways and cell types that could increase the risk of rheumatoid arthritis. It's a chronic inflammatory disorder that usually affects the joints and can be painful and disabling. The study published in the journal Nature looked at more than 100,000 people of European and Asian descent. Scientists found a definitive list of major genetic variations, which could lead to new therapies to treat the disorder. 

Scientists from the United States and Mexico have discovered a new genetic clue that could determine if a person is at risk for Type 2 diabetes. People who have the newly identified gene are 25% more likely to develop diabetes. And people who inherited the gene from both parents are 50% more likely. Scientists believe the gene might explain why Mexican and other Latin American populations are at greater risk of developing type two diabetes.

And researchers in Boston have identified a potential treatment for dry eye disease. They say the antibiotic azithromycin can stimulate the function of the cells of the gland that plays a role in dry eye. Tens of millions of Americans suffer from dry eye disease.
