Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.

According to the public databases, there are currently approximately 1,900 locations  in the human genome that produce microRNAs (miRNAs), the small and powerful non-coding molecules that regulate numerous cellular processes by reducing the abundance of their targets.  New research published in the Proceedings of the National Academy of Sciences (PNAS) this week adds another roughly 3,400 such locations to that list. Many of the miRNA molecules that are produced from these newly discovered locations are tissue-specific and also human-specific. The finding has big implications for research into how miRNAs drive disease.

Study in mice could lead to better treatment and prevention for humans.

While debate about recreational marijuana use continues, researchers are investigating the effectiveness of cannabis for treating pain, spasticity, and a host of other medical problems. In a symposium organized by the McGill University Health Centre (MUHC) as part of the 2015 American Association for the Advancement of Science Annual Meeting held this week in San Jose, California, world-renowned experts from North America and the U.K. share their perspectives on the therapeutic potential of medical cannabis and explore the emerging science behind it.

Technique could allow study of viral infections, cell division and photosynthesis in new detail.

With a low price tag and mild flavor, tilapia has become a staple dinnertime fish for many Americans. Now it could have another use: helping to heal our wounds.

A Washington University in St. Louis drug discovery program has received three grants totaling more than $5 million from the National Institutes of Health (NIH) to develop new therapeutics for respiratory diseases. The target illnesses range from the common cold to life-threatening lung disease. 

Experiments at SLAC that help explain bacterial adaptive defenses could aid in disease prevention.

Many people imagine robots today as clunky, metal versions of humans, but scientists are forging new territory in the field of 'soft robotics.' One of the latest advances is a flexible, microscopic hand-like gripper. The development could help doctors perform remotely guided surgical procedures or perform biopsies.
