Study applies game theory to genomic privacy
A new study presents an unorthodox approach to protect the privacy of genomic data, showing how optimal trade-offs between privacy risk and scientific utility can be struck as genomic data are released for research. The framework can be used to suppress just enough genomic data to persuade would-be snoops that their best privacy attacks will be unprofitable.

Scientists discover drug that increases 'good' fat mass and function
An FDA-approved drug has been identified that can create the elusive and beneficial brown fat. Mice treated with the drug had more brown fat, faster metabolisms, and lower body weight gain, even after being fed a high-calorie diet. The researchers say the technique, which uses cellular reprogramming, could be a new way to combat obesity and type II diabetes.

Opioids produce analgesia via immune cells
Opioids are the most powerful painkillers. Researchers have now found that the analgesic effects of opioids are not exclusively mediated by opioid receptors in the brain, but can also be mediated via the activation of receptors in immune cells.
