UW-Madison scientists zero in on drugs' sweet spots

... and make new drugs or enhance old ones to greater precision and effect. The series of experiments performed by Thorson's team, for example, may help researchers enhance the anti-cancer effects of digitalis and downshift its influence on the heart, thus avoiding potential detrimental effects in cancer patients...

Male elephants woo females with precise chemistry

...nd increased aggression. "This study reveals the precision and specificity of inter-animal signaling possible," co-author L.E.L. "Bets" Rasmussen, Ph.D., research professor of environmental and biomolecular systems, OHSU OGI School of Science & Engineering, said of the study published in the Dec. 22 edit...

Virginia Tech helping to develop higher quality, disease-resistant wheat varieties

...eeders use these molecular markers to increase the precision in selection of varieties having the best trait combinations. Researchers will work with USDA genotyping laboratories to provide thousands of molecular analyses required to deploy the targeted genes into breeding lines. The genetic information will...

Study in Science holds promise for a new approach to drug therapy

...e "drug-like" molecules could then be used to make precision changes in the hotspot's behavior. Any new drug would need to be able to block certain functions of the hotspot, while leaving the others in place. It would also have to be small enough to cross through the cell membrane and have its effect inside th...

Earth Rx: A microbial biotechnology prescription for global environmental health

...fic genes and their metabolic functions with great precision and detail. Other methods can now reconstruct entire genomes of what were once "unculturable" microbes. Rittmann refers to this early period as a "profitable stamp collecting" approach ?"absolutely vital in providing a cathedral foundation of know...

Molecule by molecule, new assay shows real-time gene activity

... molecules inside -- greatly increases scientists' precision in probing genetic activity. Using the new assay, described this week in the journal Science, researchers led by Harvard's X. Sunney Xie counted, one by one, protein molecules generated in small bursts within cells as multiple ribosomes bound to sin...

Common enzyme is a key player in DNA repair

...and dings are quickly fixed by the cell's fleet of precision DNA repair processes, which can surgically excise and replace a faulty section. But sometimes a damaged bit of DNA slips through unrepaired. A faulty nucleotide--the basic constituent of DNA--can stall the temperamental DNA replication machinery as ...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...ne. In aggregate, these new tests will provide the precision needed to help determine how these factors influence the genetic risk of developing disease. The goal is to produce devices for application to eventual population studies, to speed up data processing, to enhance accuracy and to reduce cost. With the...

New crop of technology reveals plant health

...ations which may range from domestic plant care to precision agriculture. "The main idea behind PLANTS is to develop a system that produces the optimal growing conditions for a crop, so that crops are kept in the best possible health with the minimum of inputs," says Dr Fiona Tooke of the Eden Project, one of...

Rice scientists make first nanoscale pH meter

...iving cells, nanoshells can be produced with great precision and the metal shells can be tuned to absorb or scatter specific wavelengths of light. To form the pH sensor, Halas' team coated the nanoshells with pH-sensitive molecules called paramercaptobenzoic acid, or pMBA. When placed in solutions of varying ...

New MRI technique shows emphysema in asymptomatic smokers

Ancient global warming drove early primates' dispersal

...he four hypotheses by comparing with unprecedented precision the times of first appearance of Teilhardina in Asia, Europe, and North America. To achieve such precision, they used a carbon isotope curve recently documented on all three continents. Carbon in the atmosphere, earth and living organisms differs in ...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...gh exerting magnetic force, and moved with extreme precision across the tips of nanowires, which are only about 200 atoms in diameter and less than a hundredth of the width of a human hair in length. "We knew we had the perfect surface on which to analyze drops of blood and other biological fluids because th...

New light microscope sharpens scientists' focus

...r-field optical microscope can be identified with precision far greater than the wavelength of light was once thought to allow. And in 1994, in work that was also published in Science, Hess and Betzig showed together that the closely packed points light in a semiconductor could be individually isolated and ...

Smell of success for nanobiosensors

...dapted to an atomic force microscope with atofarad precision (10 -15 ). This, Samitier says, could lead to medical applications to diagnose organ failure, bacterial infections or diseases such as cancer being made commercially available within a few years, as well as devices that would have a major impact on ...

Researchers add to understanding of how brain cells communicate

...open channel. They were able to use the remarkable precision of the patch clamp to see exactly when the magnesium ion entered and exited the ion channel. "Because of our currently limited understanding of NR1/2D receptors, drawing a direct link to human disease and memory is speculative, but I am confident t...

Special chip provides better picture of salmon health
