New tool predicts how long pollutants will stay in soil
...riments involving 75 chemical pollutants. She then borrowed a medicinal chemist's method of converting each of the 75 pollutants to a mathematical representation. "We worked with these numbers and came up with a very simple equation that predicts what fraction of these non-charged chemicals will make their ho...Study finds anti-HIV protein evolved millions of years before the emergence of AIDS
...ry biologists as the Red Queen Principle, a phrase borrowed from the Red Queen in Louis Carroll's "Through the Looking Glass" that refers to the paradox of running as fast as you can just to stay in place.

PITTSBURGH, April 29 Using technology borrowed from the National Aeronautics and Space Administration (NASA), scientists at the University of Pittsburgh's McGowan Institute for Regenerative Medicine have taken the first steps toward successfully preserving ovarian tissue from rats and mice in cul...New software developed at Rensselaer predicts promising ingredients for new drugs
...y predictive and don't work," Bennett said. "So we borrowed pattern recognition techniques already used in the pharmaceutical industry and added algorithms based on support vector machines. That gives us a technique to predict which molecules are promising." Rensselaer researchers noted that predictive mod...Enlisting carbon nanotubes to unmask nerve agents
... from carbon nanotubes chemically fused to enzymes borrowed from the nervous system-the same enzymes that act as catalysts in neurotransmitters. The 500-nanometer-thick tubes and their bound enzymes finely pepper a 2-by-4 millimeter sensor surface. In the presence of OP, enzyme activity is dampened. The nanot...Automated analysis of bee behavior may yield better robots
... research has revealed. "Computer scientists have borrowed some of the algorithms discovered by biologists working with insects to challenging problems in computing," Balch said. "One example is network routing, which dictates the path data takes across the Internet. In this case the insect-based network rou...ALife experiments show how complex functions can evolve
...related to vision. So, the theory goes, evolution borrowed an existing protein and used it for a new function. "Over time," Lenski said, "an old structure could be tweaked here and there to improve it for its new function, and that's a lot easier than inventing something entirely new." That's where ALife she...Artificial life experiments show how complex functions can evolve

Integration of all these methods of canopy access around a crane site will allow researchers to greatly enhance studies in canopy biology and, in particular, give them ...Photosynthesis analysis shows work of ancient genetic engineering
...o this new thing. All these metabolic pathways get borrowed and bent a bit and changed." Blankenship points out that nature's way of creating useful and complicated chemical systems through horizontal gene transfer also points to how human-directed biodesign might co-opt the process.

...inding site on bacterial DNA. Microbiologists have borrowed the term "pheromone" from entomologists because they believe that insectlike chemical signaling and communication also can occur among bacteria. But the idea of bacterial quorum sensing, which came under serious consideration only in the last decade,...ENBREL is first therapy approved for psoriatic arthritis
...urrent therapies for psoriatic arthritis have been borrowed from other diseases and do not work for everyone. Because this disease typically begins with skin plaque symptoms and then progresses to joint involvement, physicians have faced special diagnostic challenges in identifying patients with psoriatic art...Student discovers well-preserved embryo in dinosaur egg
...mb discovered that it contained an embryo after he borrowed it from Auburn University for a research project. While studying a part of the egg which previously had been cut away, he noticed three tiny bones. On a subsequent trip to Alabama, he arranged with Dr. Prescott Atkinson, an immunologist at Children's...Benefits from Alzheimer's plaque-producing reaction? Science study proposes role in gene expression

Binding domains only provide the physical link to a certain gene; they don't activate transcription by the...Lithographic technique creates neuronal networks in a dish

When a GIS researcher borrowed one of Sobrals slides defining bioinformatics and noted that most of the text still applied when "GIS" was exchanged for "bioinformatics," it was clear that the fields define their needs in silkjkljmilar ways.

The fusion protein elicited a more sustained immune response when they attached to the DNA vaccine a second plasmid encoding the protein inst...TSRI scientists clone gene that regulates circadian rhythms in plants
...ock gene, called TOC1, was identified, researchers borrowed another glow gene this one from a jellyfish and hooked it up to TOC1 to see where it works within cells.

Disease could easily sweep through the wild flock, or a natural event such as a severe storm could reduce crane numbers to a point from which recovery would be impossible. A small flock also meant that closely related birds were breeding with e...
