Commandeering cellular machinery: recognition mechanism to detect small molecules
...receptors." The receptors found by the researchers varied in their responsiveness, with some significantly more sensitive than others. Some performed the function of on-off switches, while others were more like dimmer switches, responding in proportion to the amount of LG335 bound to them.

... The MacArthur Foundation selects individuals from varied pursuits to receive this prestigious fellowship. In addition to Koller and other scientists, this year's recipients include a farmer, a poet, a ragtime pianist and a high-school teacher. Daniel J.

...t., 5, 2004 -- Patients suffering from diseases as varied as Type II diabetes, Alzheimer's, Parkinson's and dozens of lesser known maladies have one thing in common: they suffer from a large build up of amyloids, tissue that's created when millions upon millions of misfolded proteins stick together and form...Why do African-American women have more pregnancy problems?

Again, the cell configurations correlated perfectly to those of bubbles of the same number. When an aperture had one to five cells each resulted in one configuration.

When it matched the paddles' resonant frequency, the paddles began to vibrate, as measured by focusing a laser on the paddles and noting the change in reflected light, a process called optical interferometry...NYU team develops enhanced algorithm for detecting changes in cancer genomes

An earlier version of the algorithm as well as several other competing algorithms were capable of dealing with only cancer data or only polymorphism data and were unable to separate variations in cancerous an...The blotchier the face, the better the wasp

Because these wasps are social insects that form multi-queen nests, she wondered whether the markings had significance to the wasps. Researchers already knew that in such nests, the wasps establish a dominance hierarchy by fighting...New study links low fish supply to increased bushmeat hunting
...ranged from 230,000 to 480,000 tons in a year, and varied by as much as 24 percent between consecutive years. The researchers found that years with a lower-than-average supply of fish had higher-than-average declines in land-based wildlife abundance. This relationship was seen regardless of other pote...Ubiquitination in real-time: A world first at the Universit de Montral
