Computers close in on protein structure prediction

...ted computing project that they are hoping will be aided by members of the public. The project, called Rosetta@home, is a scientific research project that uses internet-connected computers to predict and design protein structures, and protein-protein and protein-ligand interactions. The goal is to develop ...

'Computer-chemistry' yields new insight into a puzzle of cell division

Duke University biochemists aided by Duke computer scientists and computational chemists have identified the likely way two key enzymes dock in an intricate three-dimensional puzzle-fit to regulate cell division. Solving the docking puzzle could lead to anticancer drugs to block the ...

Scientists a step closer to protecting world's most important crop

...equence of the rice blast fungus genome, which has aided the current research. ...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...he signals to the injured section of the heart and aided in repair. These cells have also been studied for different diseases and have been shown to follow inflammatory signals to various areas of the body to aid in repair. The delivered cells are expected to respond to the body's own signals and migrate ...

How 'hot' emotional brain interferes with 'cool' processing

...e, the haunting memories of PTSD sufferers will be aided by the fMRI technique the researchers developed to precisely measure this distraction, they said. The researchers, Florin Dolcos and Gregory McCarthy, published their findings in the Feb. 15, 2006, issue of the Journal of Neuroscience. Their work wa...

Sun protection for plants

...tion. This photoprotective process was found to be aided by a special carotenoid molecule called zeaxanthin and plants with higher levels of this molecule appear to be better protected. Professor Peter Horton, research leader at the University of Sheffield, said, "Plants use a range of processes to adapt ...

High-resolution light microscope reveals the fundamental mechanisms of nerve communication

...spatial distribution of the bruchpilot protein and aided neurobiologists from the European Neuroscience Institute and the University of Würzburgin understanding the protein's central role in the formation of active synaptic zones. STED microscopy radically distinguishes itself from conventional farfield li...

World Trade Center identifications pushed forensic DNA technology

...ching environment, patience and understanding were aided by familiarity and trust. While samples of the living are replaceable, it quickly became apparent that degraded DNA made the use of STR by itself impossible in many victim identifications. Shaler and colleagues decided to look at two other DNA m...

Study shows hope for ridding lakes of clawed invader

...species. Since 2001, the UW-Madison researchers, aided by a small army of undergraduate students and the Wisconsin Department of Natural Resources (DNR), has succeeded in significantly reducing the population of rusty crayfish in Sparkling Lake through a program of intensive trapping and manipulating fis...

Researchers map out networks that determine cell fate

...issues. Understanding of leukemias also could be aided by insight into this regulatory circuitry, Singh said. Many leukemias exhibit mixed-lineage patterns of gene expression, for example of both macrophage and lymphocyte genes. "It may be that these cells are stuck in a progenitor-like state," said S...

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

...Los Alamos National Lab in New Mexico. They were aided by ASU postdoctoral research fellow Solitaire Lindsay and graduate students Dongqing Yang, Pavan Aella and Ana Egatz-Gomez. The ASU group's work is part of the international effort by the Interdisciplinary Network of Emerging Science and Technology...

Ready, set, mutate?and may the best microbe win

...f the mutant proteins to document precisely how it aided in metabolic regulation. The fermentor experiment was repeated and the same mutations ?and no others ?were observed to develop again. Three of the six genes ?the "winner," it's closest competitor and Q199R ?were spliced back into the original form of...

Far more than a meteor killed dinos

...microfossils are saying is that Chicxulub probably aided the demise of the dinosaurs, but so did Deccan trap volcanism's greenhouse warming effect and finally a second huge impact that finished them off. So where's the crater? "I wish I knew," said Keller. "There is some evidence that it may have hit in...

'Fruit fly dating game' provides clues to our reproductive prowess

...microfossils are saying is that Chicxulub probably aided the demise of the dinosaurs, but so did Deccan trap volcanism's greenhouse warming effect and finally a second huge impact that finished them off. So where's the crater? "I wish I knew," said Keller. "There is some evidence that it may have hit in...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...n Virginia Medical School, Norfolk, Va., proteomic aided investigation of the mechanistic basis for HZE-induced cognitive impairment and the development of diagnostic biomarkers David Chen, University of Texas Southwestern Medical Center, Dallas, mechanisms of the repair of HZE-induced DNA double-strand...

Cigarette smoking impedes tendon-to-bone healing

...asically, all healing and all repair processes are aided by the formation of new blood vessels that bring in new cells. That process is assisted by increases in blood supply that may not happen as efficiently in smokers." ...

Vaccine-producing 'plant-factories'

...uñoz and Edurne Baroja. These scientists have been aided by a research team from Niigata University (Japan). Specifically, the study describes a new route for the traffic of proteins from the reticular/Golgi system where there are glycosylates, towards the chloroplasts of the plant cell. Some of these g...

Conceptualizing a cyborg

...re then slowly pulled apart over a series of days, aided by a precise computer-controlled motor system, until they reached a desired length. For the interface, one of the plates is an electrical microchip. Because Smith and his team have shown that stretch-grown axons can transmit active electrical si...

Hives ferment a yeasty brew, attract beetle pest

...gent in cleaning their hives. The beetles are also aided in their invasion by a yeast that naturally occurs on pollen and produces, as a fermentation product, the alarm chemical that draws the beetles. "It is possible that bees are being habituated to a low level of alarm hormone," says James H. Tumlins...
