Switchable adhesive

...ose their charge, and the electrostatic attraction lets up. The two surfaces can then be slowly and carefully separated from each other without any damage. This detachment is reversible: If the pH value is raised again, making the solution less acidic, the gel and brush stick to each other once again. Thi...

Doing nature one better: Expanding the genetic code in living mammalian cells

...hich no corresponding tRNA/amino acid pair exists lets everybody know that this particular job is done. From a large pool of mutated aminoacyl-tRNA synthetases the enzyme that loads tRNAs with their corresponding amino acids Wang selected the one that would attach a desired artificial amino acid to ...

University of Colorado invention may allow thirsty crops to signal farmers

...trusive device that gently rests on the plants and lets them interface with the digital world," he said. "Basically, this is a device that will allow plants to talk to humans and communicate their needs, like when to water and apply fertilizer." Stoner is the principal investigator on a $150,000 Sma...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...and place its amino acids in a reverse order, that lets the virus in," Lehrer said. "We would like to learn why it happens, but at the moment there's no explanation for this paradoxical result." Still, the findings seem to show promise in gene therapy. ...

Researchers identify key gene that may be a marker of breast cancer metastasis

...ibitors. AIs shut down an enzyme, aromatase, that lets the body produce estrogen outside the ovaries. These drugs represent one of the newest, most effective forms of hormone therapy for postmenopausal women whose breast cancer tests positive for estrogen receptors, which means that estrogen in the body...

Bacteria control how infectious they become, study finds

...expression is limited, it seems that its structure lets it control key sequences of the genome during transcription, the process of transferring genetic information inside a cell and one of the first steps of gene expression. Making RfaH work only at specific sites is, in a sense, a genius way to preven...

Structural basis for photoswitching in fluorescent proteins brought into focus

... you can activate only a small group of them. That lets you follow the motion of subsets of molecules. We wanted to understand the process, so that we can permanently switch them off and on or vary the time delay." However, he said, the mechanism of photoswitching was unknown, and in many cases the prot...

New science of metagenomics 'will transform modern microbiology'

...plant growth, the new report says. "Metagenomics lets us see into the previously invisible microbial world, opening a frontier of science that was unimaginable until recently," said Jo Handelsman, Howard Hughes Medical Institute Professor, departments of plant pathology and bacteriology, University of W...

Fruit fly gene research may shed light on human disease processes

... the common fruit fly Drosophilia melanogaster -- lets us conduct more sophisticated experiments than can be undertaken in humans. These simple organisms can be grown cheaply in test tubes, fed on yeast, corn meal and molasses, yet their embryos, which can be seen with the naked eye, undergo many of the ...

Light-activated compound silences nerves, may one day help epileptics

...dentify or create an animal model of epilepsy that lets them test the NBD-steroid's potential as a therapeutic. They are also looking for a new fluorescent tag that responds to longer wavelengths of light. Unlike many photoactive compounds, the NBD-steroid responds not to ultraviolet light but to light f...

Magnetic resonance microscopy research lands professor NSF award

...resonance imaging, or MRI. However, MRM technology lets researchers see movies of fluids and gases moving through objects honeycombed with tiny channels. "We know a lot about how water, or other fluids, flow through large channels, like rivers and the plumbing in your house, but there is a lot that's n...

Diesel exposure model reduces allergy risk assessment errors

...proximity models," says Ryan, "land use regression lets us consider more complex exposure factorslike elevation and the type or number of passing vehiclesin our initial assessment. This allows us to create buffers around specific sample sites and control for factors influencing that locations overall dies...

New research finds people and pigeons see eye to eye

... identify a AA battery from the side profile. But, lets say the person could see the same battery only from the bottom with the negative terminal. From this perspective, the only visible outline would be a circle; from the bottom, the corners of the battery now are not visible and information about the co...

Molecular motors and brakes work together in cells

...sor of Cell and Developmental Biology. "This study lets us have a more complete picture." Microtubules are structures that help give shape to many types of cells, form the spindle -- a structure important in cell division -- and act as a railroad, of sorts, upon which molecular motors move protein packa...

UCF scientists' molecular discovery could help drugs target unhealthy cells

Conducted in the Bartels Lab, the research was funded by the U.S. Department of Energy, the Petroleum Research Fund and the Air Force Office of Scientific Research. The San Diego Supercomputer Center provided r...

Treatments for urinary infections leave bacteria bald, happy and vulnerable

...ili, which are capped by an adhesive compound that lets them attach to and invade host cells. "E. coli is a Gram-negative bacterium, so it has an inner and an outer membrane, and many of its most important tools for interacting with the outside world are assembled in the space between the membranes," Pin...

NIH Nanomedicine Center draws on NYU School of Medicine expertise

...gical systems. The instrument is a microscope that lets scientists hold and handle a snippet of DNA. Like a yo-yo in water, the DNA segment is suspended in a tiny vial of liquid. The top end is attached to a glass slide and a tiny magnetic bead is affixed to the bottom end. In this setup, moving a magn...

Research yields new insights into the cause of diabetes

... that secrete insulin. Using genetics in this way lets the organism tell you what is important to normal function." Normally, the beta cells of the pancreas respond to high levels of glucose in the blood by producing the precursor of insulin -- proinsulin -- in the endoplasmic reticulum. Inside this and...

Taking 'chips' to the next level of gene hunting

...tic information of current DNA chips. "This one lets us look at twice as much as we could in the past, which means essentially that all chip experiments become faster and cheaper and can be done on an ever larger scale," says Boeke. The chips his team currently uses cost about $400 per experiment. If t...
