A signal that triggers half the stem cells in the developing brain to commit suicide at a stage where their survival will likely do more harm than good has been identified by researchers at the Medical College of Georgia and the University of Georgia.

Identifying the factors that result in the timely, massive cell suicide is important to understanding the developmental puzzle, the researchers say of the work featured on the cover of the Aug. 4 issue of the Journal of Cell Biology.

Swift or safe? That may be the question drivers with navigation systems ask themselves in future.

A new study by researchers at the University of Toronto Intelligent Transportation Systems (ITS) Centre and Testbed suggests in-car systems, designed to guide drivers around traffic jams and accidents quickly, could actually cause a temporary surge in the risk of accidents. “Discovering that traveller information systems may be good for travel time but not for overall safety was shocking

Introduction – Enzymology in 2003

Why the 90th anniversary of v = Vmax x [S] / (Km + [S]) is as important as the 50th anniversary of the double-helical structure of DNA. Enzymology is essential, to find out how nucleic acids fulfil their biological functions. Moreover, genome analysis will always, at some stage in the process, have to advance from sequence gazing to enzymology, since the objective of the analysis must be to identify the reactions mediated by the products of each open

Patients to benefit from new ultrasound qualification developed by Sheffield Hallam University

A new postgraduate qualification in ultrasound practice has been developed by Sheffield Hallam University to ensure health professionals offering scans are competent and safe to practice.

The University has a national reputation for excellence in ultrasound education and training. It already offers six specialist postgraduate certificates in medical, obstetrics and gynaecological,

On August 18th and 19th in Stanford, California, at Hot Chips 15 conference, the most important international event on processors architecture, mAgic VLIW will be presented: it is a revolutionary electronic component derived by technologies developed by Italian National Institute for Nuclear Physics (Infn) in the context of the special project Ape and conceived by the Italian company Ipitec, financed by Atmel. The processor will be produced by Atmel itself, a world-wide leader in the semiconducto

Which design principles unify the diversity of life on earth? To understand how biological designs emerged by natural selection, biomechanics studies organisms by applying engineering science and mechanics. Biomechanics studies life from molecules to ecosystems. Questions range ‘how do cells form tissue’, over ‘what shapes a muscle’ to ‘how do animals fly’ and ‘which mechanical constraints govern body shape and -dynamics when animals increase in size’. Biomechanics is applied not only to extant b
