Large waist circumference leads to lower life expectancy even among people with healthy body mass index (BMI) according to the results of a new study in Mayo Clinic Proceedings. The study from researchers in the USA, Australia, Sweden, Norway and Finland found a linear association between waist circumference and all-cause mortality.

Scientists at The Scripps Research Institute (TSRI) have discovered an important mechanism underlying sensory feedback that guides balance and limb movements. The finding, which the TSRI team uncovered in fruit flies, centers on a gene and a type of nerve cell required for detection of leg-joint angles. “These cells resemble human nerve cells that innervate joints,” said team leader Professor Boaz Cook, who is an assistant professor at TSRI, “and they encode joint-angle information in the same way.”

Some commonly used drugs that combat aches and pains, fever, and inflammation are also thought to have the ability to kill bacteria. New research appearing online on March 13 in the Cell Press journal Chemistry & Biology reveals that these drugs, better known as NSAIDs, act on bacteria in a way that is fundamentally different from current antibiotics. The discovery could open up new strategies for fighting drug-resistant infections and ”superbugs.”

“Cell movement is the basic recipe of life, and all cells have the capacity to move,” says Roberto Dominguez, PhD, professor of Physiology at the Perelman School of Medicine, University of Pennsylvania. Motility – albeit on a cellular spatial scale -- is necessary for wound healing, clotting, fetal development, nerve connections, and the immune response, among other functions. On the other hand, cell movement can be deleterious when cancer cells break away from tumors and migrate to set up shop in other tissues during cancer metastasis.

Only one third of individuals identified as being at clinical high risk for psychosis actually convert to a psychotic disorder within a 3 year follow-up period. This risk assessment is based on the presence of sub-threshold psychotic-like symptoms.

New-onset Crohn’s disease is characterized by changes in the populations of gastrointestinal bacteria. This involves reduction in abundance of beneficial, anti-inflammatory microbes and increases in bacteria that promote processes such as inflammation and complications such as colorectal carcinoma. These are the findings of a large new multi-centre North American study to be published in the journal Cell Host and Microbe on March 12th. Furthermore, the study finds that the use of antibiotics can increase the microbial imbalance, tilting it further towards pathogenic organisms.
