Vitamin D levels linked to weight-loss surgery outcomes

Low levels of vitamin D have long been identified as an unwanted hallmark of weight loss surgery, but new findings from a study of more than 930,000 patient records add to evidence that seasonal sun exposure -- a key factor in the body's natural ability to make the "sunshine vitamin" -- plays a substantial role in how well people do after such operations.

Researchers successfully target 'Achilles' heel' of MERS virus

Researchers studying the Middle East Respiratory Syndrome, or MERS, have found molecules that shut down the activity of an essential enzyme in the virus and could lead the way to better treatments for those infected. The team identified molecules that inhibit an enzyme essential to MERS virus replication, and also discovered a characteristic of the enzyme that is very different from other coronaviruses. More...

Scientists reveal epigenome maps of the human body's major organs

While the genome of an individual is the same in every cell, epigenomes vary since they are closely related to the genes a cell is actually using at any given time. More...
