Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell.Except for cancer, samples of diseased tissue are difficult or even impossible to take from living patients. Thus, the vast majority of genetic samples used in large-scale studies come in the form of blood. However, if it turns out that blo... More

The Human Genome Project took 13 years to fully sequence a single human's genetic information. At Washington University's Genome Center, they can now do one in a week. But when you're generating that much data, just keeping track of it can become a major challenge.... (Source: http://radar.oreilly.com/2009/07/sequencing-a-genome-a-week.html)

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from a brain.The multiple brain scans from MRI, fMRI, diffusion tensor imaging, and computed tomography angiography were fused and installed into a surgical guidance computer. By revealing the tumor's relationship to all of the functional centers, and... More

Tokyo University researchers have succeeded in genetically modifying a male silkmoth so that it reacts to light instead of odor, or to the odor of a different kind of moth -- the first step in a plan to develop a robo-bug that could sense illegal drugs (several kilometers away), landmines, people buried under rubble, or toxic gas. Their ultimate goal is to understand human brains and restore connections damaged by diseases and accidents. (Source... More

(Wiley-Blackwell) A team working with Rustem F. Ismagilov at the University of Chicago has demonstrated that the absolute number of cells is irrelevant to The process of quorum sensing; only the number of bacteria in a given volume plays a role. They were even able to trigger quorum-sensing processes in single cells when these were confined in extremely small volumes.
