Researchers at the universities of Leicester and Oxford have made a discovery about plant growth which could potentially have an enormous impact on crop production as global warming increases.

Dr Kerry Franklin, from the University of Leicester Department of Biology led the study which has identified a single gene responsible for controlling plant growth responses to elevated temperature.

Dr Franklin said: "Exposure of plants to high temperature results in the rapid elongation of stems and a dramatic upwards elevation of leaves".

UPTON, NY - Building on the idea of using DNA to link up nanoparticles - particles measuring mere billionths of a meter - scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction. Such reliable, reproducible nanofabrication is essential for exploiting the unique properties of nanoparticles in applications such as biological sensors and devices for converting sunlight to electricity. The work will be published online March 29, 2009, by Nature Materials.

A type of surgery which reshapes the scarred left ventricle, the main pumping chamber of the heart, and is often done in conjunction with heart bypass, not only failed to reduce deaths and hospitalizations in heart failure patients but also did not improve patients' quality of life compared to bypass alone after four years of follow-up, according to the results of a large international clinical trial funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health.

(PHILADELPHIA) – A clinical study of cardiac patients who suffered an allergic reaction to the widely-prescribed drug clopidogrel, also known by the pharmaceutical name Plavix, found that treatment with a combination of steroids and antihistamines can alleviate the allergic reaction symptoms thereby allowing patients to remain on the drug, say doctors from Thomas Jefferson University Hospital. The study followed 24 patients, who developed Plavix allergies after undergoing coronary stent procedures.
