Can Twitter Help Better Identify Foodborne Illness Cases?

August 18, 2014 12:33 pm | News | Comments

An estimated 55 million to 105 million people in the United States suffer from foodborne illnesses each year, according to the CDC, resulting in costs of $2 to $4 billion annually. What if Twitter could be used to track those cases and more quickly identify the source of the problem?

Epigenetic Breakthrough Bolsters Understanding of Alzheimer’s

August 18, 2014 12:12 pm | News | Comments

A team of researchers has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer’s disease. The current study found that chemical modifications to DNA within the ANK1 gene are strongly associated with measures of neuropathology in the brain.

Single Enzyme is Necessary for Development of Diabetes

August 15, 2014 11:04 am | News | Comments

An enzyme called 12-LO promotes the obesity-induced oxidative stress in the pancreatic cells that leads to pre-diabetes, and diabetes. 12-LO’s enzymatic action is the last step in the production of certain small molecules that harm the cell, according to a team from Indiana University School of Medicine. The findings will enable the development of drugs that can interfere with this enzyme, preventing or even reversing diabetes.
