Researching The Cause Of Programmed Cell Death

Researching The Cause Of Programmed Cell Death
Walter and Eliza Hall Institute researchers have put an end to a 10-year debate over which form of a molecular messenger called Fas ligand is responsible for killing cells during programmed cell death (also called apoptosis).

Calcium Scans May Be Effective Screening Tool For Heart Disease

Calcium Scans May Be Effective Screening Tool For Heart Disease
A simple, non-invasive test appears to be an effective screening tool for identifying patients with silent heart disease who are at risk for a heart attack or sudden death. Coronary artery calcium scans can be done without triggering excessive additional testing and costs, according to the multi-center EISNER (Early Identification of Subclinical Atherosclerosis by Noninvasive Imaging Research) study, led by investigators at the Cedars-Sinai Heart Institute.

E. coli's Kayak Paddle-Lke Motion Tracked For First Time

E. coli's Kayak Paddle-Lke Motion Tracked For First Time
Yale engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. Their findings, which appear online September 29 in the journal Physical Review Letters, will help lead to a better understanding of how bacteria move from place to place and, potentially, how to keep them from spreading. Scientists have long theorized that the cigar-shaped cell bodies of E.
