Injections of a stimulant agent into rat brains expanded blood vessels and improved blood flow, a finding that may lead to a new, non-invasive way to prevent stroke, researchers reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.

Rats treated with the growth-promoting substance granulocyte macrophage-colony stimulating factor (GM-CSF) had almost twice as much arteriogenesis, the expansion of a brain artery, after one week compared to rats given s

A strain of E. coli that causes severe, sometimes deadly, intestinal problems relies on signals from beneficial human bacteria and a stress hormone to infect human cells, a researcher at UT Southwestern Medical Center at Dallas has discovered.

The finding, which will appear online today in Proceedings of the National Academy of Sciences, could lead to the development of beta blockers as a therapy to impede this cellular signaling system, causing the harmful bacteria to pass blindly through t

Madrid, Spain: Scientists believe that they are an important step nearer to success in creating an artificial egg from the combination of the nucleus of a somatic cell and an oocyte which has had its DNA-carrying nucleus removed, a conference of international fertility experts heard today (Tuesday 1 July).

Dr Peter Nagy, from Reproductive Biology Associates, Atlanta, collaborating with the University of Connecticut, USA, told the European Society of Human Reproduction and Embryology annual

When ten Eastern European countries join the EU next year, internal trade will increase and the structures of the agricultural and food sectors will change in both old and new Member States. This was the message of JOHAN SWINNEN, Professor of Agricultural Policy of the Katholieke Universiteit Leuven in Belgium, addressing delegates at the opening of the Nordic Association of Agricultural Scientists (NJF) congress in Turku, Finland, last Tuesday. Swinnen is one of the world’s leading experts on the Ag

Gemini Observatory’s new spectrograph, without the help of adaptive optics, recently captured images that are among the sharpest ever obtained of astronomical objects from the ground.

Along with the images and spectra acquired during recent commissioning of the Gemini Multi-Object Spectrograph (GMOS) on the 8-metre Gemini South Telescope in Chile, one image is particularly compelling. This Gemini image reveals remarkable details, previously only seen from space, of the Hickson C

A new approach that makes paper from straw, which cuts production costs and is kinder to the planet, is one step closer to reality thanks to an investment award of £90,500 from NESTA (the National Endowment for Science, Technology and the Arts) – the organisation that nurtures UK creativity and innovation.

The innovation is the brainchild of a Surrey-based environmental company, BioRegional MiniMills Ltd. The driving force behind this company is a former nurse, Sue Riddlestone who became ver
