Fires in homes and offices could be tackled more efficiently using technology that predicts how a blaze will spread.
A new technique is able to feed data taken from sensors located in burning buildings into computer models so that rescue services can predict how fires will spread.
The technology could save firefighters valuable time by giving several minutes of warning on how a fire will develop, helping them to contain the blaze and minimise its impact.
WASHINGTON — The number of people infected with HIV/AIDS in sub-Saharan Africa is projected to far outstrip available resources for treatment by the end of the decade, forcing African nations to make difficult choices about how to allocate inadequate supplies of lifesaving antiretroviral therapy (ART), says a new report by the Institute of Medicine. It calls for a renewed emphasis on reducing the rate of new infections, promoting more efficient models of care, and encouraging shared responsibility between African nations and the U.S.
The Great Tit is a common garden bird of many countries in Europe and Asia. Great Tits are generally thought of as fairly inquisitive but it has long been known individuals vary considerably in their willingness to explore new surroundings. Some birds – known as "fast" or "proactive" – are quick explorers and are comparatively aggressive, whereas "slow" or "reactive" birds are more cautious.
Medical scientists at the University of Leicester have identified for the first time a new way in which our body controls the levels of sugar in our blood following a meal.
They have discovered the part played by a particular protein in helping to maintain correct blood sugar levels.
The rate of global warming could lead to a rapid release of carbon from peatlands that would further accelerate global warming.
Two recent studies published by the Mathematics Research Institute at the University of Exeter highlight the risk that this 'compost bomb' instability could pose, and calculate the conditions under which it could occur.
The same Exeter team is now exploring a possible link between the theories described in the studies and last summer's devastating peatland fires in Russia.
Amazonia's huge biodiversity originated with the formation of the Andes and, as such, dates back further than previously realised, claims an article written by an international research group, headed by a researcher from the University of Gothenburg, published in the journal Science.
King's College London, in collaboration with Radboud University Nijmegen Medical Centre in The Netherlands, has discovered a new gene associated with Hypospadias, the congenital malformation of the male genitalia. The research was published today in Nature Genetics.
Researchers at Delft University of Technology and Oxford University announce a new type of nanopore device that could help in developing fast and cheap genetic analysis. In the journal Nature Nanotechnology (November 28), they report on a novel method that combines man-made and biological materials to result in a tiny hole on a chip, which is able to measure and analyze single DNA molecules.

An international team of scientists has developed a new technique to aid crops at risk from a devastating agricultural parasite commonly known as the 'honey fungus', one of the most serious diseases of trees and shrubs across the northern hemisphere. The development allows crop to be screened for natural resistance by adding DNA with fluorescent genes to the fungus before being planted out.
The dance of cell division is carefully choreographed and has little room for error. Paired genetic information is lined up in the middle of the cell in the form of chromosomes. The chromosomes must then be carefully pulled apart so that the resulting daughter cells each have an identical copy of the mother cell's DNA.
A team of researchers from Spain and Latin America have synthesized two iron compounds that inhibit the in vitro growth of Mycobacterium tuberculosis, the bacteria that causes tuberculosis. Due their low level of toxicity in mammel cells, the compounds could be used in the future as therapeutic agents and hospital disinfectants.
Doctors treating female epilepsy patients have to take account of the specific hormonal situation in women. Such an approach can often reduce the limitations imposed by the disease. This is the conclusion reached by Sabine Weil of Munich University and her co-authors in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2010; 107(45): 787-93).
HACKENSACK, N.J. (November 22, 2010) – The John Theurer Cancer Center at Hackensack University Medical Center announced today that it will present research updates and clinical trial results of 40 cutting-edge studies at the 52nd Annual American Society of Hematology (ASH) Meeting in Orlando from December 4 – 6.
