Commandeering cellular machinery: recognition mechanism to detect small molecules
...ied RXR.) Though the goal was 32,768 variants, the method
actually produced approximately 380,000 samples which would have been impossible to test using conventional screening methods. However, Doyle and his research team used a new protein engineering technique known as chemical complementation that allo...
Stanford cooling tool may improve performance of athletes, soldiers
...formance. Two Stanford biologists have developed a method
for cooling that maximizes heat transfer through the palms of the hands. The idea is to engorge confluences of arteries and veins located there by mechanically drawing blood into them. The technology was used by some athletes during training for the ...
Protein energy profiles offer clues about amyloids
...colleagues believe they are creating a statistical method
that will help scientists predict which proteins are prone to misfold. "In designing a computer model for protein folding, you can't take everything into account because there are too many variables," said Vijay Pande, assistant professor chemistry a...
New method identifies chromosome changes in malignant cells

for identifying alterations to chromosomes that oc...student Chad Myers and other colleagues invented a method
for quickly analyzing an entire genome -- all the genes contained in a cell -- and producing a relia...
UF scientists have bionanotechnology recipe to find elusive bacteria
...aid. The secret to the UF team's super-sensitive method
is in the sauce: The silica structure they use to bind the antibody-and-dye amalgam together allows each particle to hold thousands of dye molecules, rather than just one, making the fluorescent signal hundreds to thousands of times brighter. Enhanc...
Acoustics meeting in San Diego
... ( email@example.com ) will demonstrate a new method
for detecting subtle damage in composite materials by using time-reversed acoustics. In this approach, a device sends a short pulse of ultrasound to a material and detects the long echo caused by the initial pulse as it spreads out, as well as multi...
A new culprit in depression?
... of 32 post-mortem brain samples -- the microarray method
can simultaneously measure the level of activity of tens of thousands of genes that are functional in a given tissue. The researchers found that levels of molecules called fibroblast growth factors (FGFs), and two of the receptors that bind to them, ...
NHGRI seeks next generation of sequencing technologies
...a exists. In order to reduce labor and costs, this method
emphasizes the miniaturization of each step, from sample preparation to DNA sequencing. The platform enables one person to fragment, amplify, sequence and assemble an entire genome, regardless of the genome's size. John Williams, Ph.D., LI-COR Inc.,...
Study identifies target for preventing sexual transmission of HIV
... be done before we have an affordable, easy to use method
of blocking transmission of HIV through the vaginal membranes," Dr. Lederman said. "But we have taken an important step. Now that we have shown that it is possible to block SHIV transmission through the vagina in macaques and have identified the targ...
Purdue chemists give an old laboratory 'bloodhound' a sharper nose
...ray ionization (DESI) - a mouthful of a name for a method
that is relatively simple to conceive. "Our device sprays a sample with a stream of high-velocity gas that contains some reactive chemicals," Gologan said. "Just like a strong wind kicks up dust, the gas breaks off a few small particles of the ...
Sniffing out the culprits of dust allergies
...ovel combined-library approach for this purpose--a method
that enabled simultaneous identification of proteases from complex samples and isolation of protease-specific inhibitors. In this way, Der 1 p was identified as an active cysteine protease in dust mite extracts, and a Der 1 p-specific small-molecule ...
S1P1 essential for tumor growth and is blocked by RNA interference
...rs then developed an RNA interference technique, a method
that specifically blocks S1P1 expression. They showed that using RNA interference they successfully blocked S1P1 expression in cell culture and that when they injec-tion of the S1P1-specific interfering RNA into tumors in mice, these also showed rep...

Economics and ecology combine at UGA in NSF-funded study of evolutionary game theory
