Innovative worm study provides new insights into genetics of addiction-prone drugs. A team at Scripps Research in Florida has discovered a biological system that manages cells’ response to opioid drug exposure. The unexpected discovery offers new ideas for improving the safety of the one of the most effective, and most abused, group of pain medications.

In a paper published as a “First Release,” in the journal Science, lead authors Kirill Martemyanov, PhD, and Brock Grill, PhD, describe how they designed and implemented a new, unbiased approach for decoding the genetic network that controls actions of opioids in a nervous system.

They used a small soil d...

Self-calibrating technology opens new opportunities for medicine and research. Researchers have developed a new self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical or mechanical components, the tip of the endoscope measures just 200 microns across, about the width of a few human hairs twisted together.

As a minimally invasive tool for imaging features inside living tissues, the extremely thin endoscope could enable a variety of research and medical applications...

Fatigue affects majority of MS patients, impacting quality of life and ability to work full time. Higher levels of blood high-density lipoprotein (HDL) may improve fatigue in multiple sclerosis patients, according to a new University at Buffalo-led study.

The pilot study, which investigated the effects of fat levels in blood on fatigue caused by multiple sclerosis, found that lowering total cholesterol also reduced exhaustion.

The results, published recently in PLOS ONE and led by Murali Ramanathan, PhD, professor in the UB School of Pharmacy and Pharma...

Researchers at Karolinska Institutet in Sweden have discovered a new sensory organ that is able to detect painful mechanical damage, such as pricks and impacts. The discovery is being published in the journal ‘Science’.

Pain causes suffering and results in substantial costs for society. Almost one person in every five experiences constant pain and there is a considerable need to find new painkilling drugs. However, sensitivity to pain is also required for survival and it has a protective function...
