Engineering a solution to waste crisis
...in Carmarthenshire, West Wales, they are analysing constant readings of temperature, gas flows, and gas composition, to develop the most efficient ways of producing valuable compost from material which would otherwise be discarded. Through this work, largely sponsored by Carmarthenshire Environmental Resourc...Gene clustering helps rice plants fight pathogens
...ever-evolving battle between rice and pathogens "a constant arms race." "Pathogens mutate to bypass resistance mechanisms, while the host, rice, recombines various components in resistance genes so it can again recognize pathogens. These resistance genes are like generals in a battle who recognize what's goin...New findings suggest colorectal cancer origins are different than previously thought

My project's focus was to use computer simulations to study anomalous diffusion (how particles move through unordinary media) and is related to the study of percolation. The computer simulations allowed us to test a sp...Key regulatory enzyme is a molecular 'octopus'
...the ability to damp their signaling in the face of constant stimulation," said Lefkowitz. "Years ago, we had discovered that this down-regulation occurs due to a phosphorylation of the activated receptor that triggers binding of a protein called beta arrestin. This protein stops further G protein signaling an...Mediterranean fishery recovers, thanks to manmade pollutants

"A constant stream of suitors wanting to participate in a polygamous free-for-all could possibly lead to greater harassment, leading to the female expending more energy and placing herself at greater risk of harm than if she doted on just the one male," says Elg...Models show gene flow from crops threatens wild plants

That is, they consider a crop that is more different genetically and a wild population that is small or varies in ...The 'fixed' hotspot that created Hawaii was not stationary after all, study finds

By measuring the number of potassium-derived argon atoms in the samples, researchers were able to estimate that the submerged volcanoes formed some 47 million to 81 million...Swimming can contribute to rebuilding bone strength

For most of the time, the skeleton responds to mechanical loading generated though exercise by increasing bone mass and strength. In human studies...Discovery may help in war against fire ants
