Triple threat polymer captures and releases

...philic to hydrophobic. The complex surface that is created makes it difficult for marine organisms to establish a toehold. Her laboratory has produced these novel materials and they are being used around the world Wooley and her collaborators were intrigued by the surface of these nanostructured material...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

...nic circuits to meet the very demanding challenges created by future nano-scale electronic components. These components will be so small that their behaviour will be highly variable, governed by individual atoms rather than the average behaviour of large collections of atoms. The NanoCMOS project will bu...

Researcher studies, treats military with 'silent disease'

...s Peer Reviewed Medical Research Program. Congress created the program in 1999 to promote research in health issues the military faces. Since its inception through 2005, the program has spent almost $300 million to fund nearly 200 projects in a range of medical topics, including combat casualty care and tech...

Loosen up, DNA: Leukemia gene changes genetic packaging

...plex experiment involving fruit flies. Researchers created flies with normal amounts of the signaling system and compared them to mutant flies with increased or decreased JAK/STAT signaling. They moved the location of the "red-eye reporter gene" around, sometimes inserting it into a "quiet" stretch of DNA, s...

UCI scientists find chlorine may contribute to ozone formation

...llution levels. They also don't know for sure what created the chlorine they detected. "We found more chlorine in the daytime than expected. It must be rapidly produced, because sunlight destroys it so quickly," Saltzman said. "Most likely the process involves airborne marine particles, but research is need...

Mapping the protein world

...0 citations in the scientific literature. This has created an incredible drive for further scientific development," Lamzin says. "The new funding gives us a push to advance the software's ability to recognise and distinguish different types of macromolecular objects, for example DNA, and to improve the autom...

The shape of life: research sheds light on how cells take shape

...ames Valles and Jay Tang puzzled over the patterns created by proteins called microtubules. Shaped like long, skinny straws, these proteins are puny ?they measure only about 250 atoms wide ?but play critical roles in the body. Microtubules help cells divide. They also act as scaffolds, giving cells their sha...

Ten years later, Dolly is still making headlines

... lead researcher for the team who - 10 years ago - created the cloned sheep "Dolly," will kick off the 2006 American Association of Pharmaceutical Scientists' (AAPS) National Biotechnology Conference in Boston, June 18-21. At the meeting, nearly two-thousand of the world's leading scientists will discuss a ...

Airborne mold spores increase kids' risk for multiple allergies

...findings reinforce the idea that not all fungi are created equal, says Tiina Reponen, PhD, professor of environmental health at UC and corresponding author on the study. "It turns out that the health effects of airborne fungal spores are more complicated than we thought," she says. "It's not enough to look ...

When it comes to gene transcription, random pauses aren’t quite so random, study finds

... in Block's lab and lead author of the Cell study, created experimental DNA templates using a special 240-base pair sequence that triggers one of two types of long pauses in RNAP--a "backtracking pause" associated with gene regulation in which the enzyme reverses direction briefly; or a "hairpin pause, " nam...

South Pacific plant may be missing link in evolution of flowering plants

Think fast! Rice undergrad unlocks nerve speed secret

...Columbia University's James Rothman and colleagues created mutant cells with SNAREs on the outside rather than the inside, and they used the cells to show that complexin could inhibit fusion that would otherwise be expected to proceed. "Complexin is the brake," McNew said. "It says, 'Stop. Don't go any fur...

New light microscope sharpens scientists' focus

...alize its center, Hess said. When a final image is created that includes the center of each individual molecule, it has a resolution previously only achievable with an electron microscope. Unlike electron microscopy, however, the new technique allows for more flexibility in labeling molecules of interest. ...

Study reveals how cells destroy faulty proteins in cystic fibrosis

The cellular system that degrades faulty proteins created by the cystic fibrosis gene has been identified by University of North Carolina at Chapel Hill scientists. Turning off the degradation system allows some proteins to regain their proper shape, offering a new avenue for treatments aimed at curing the ...

Schepens scientists are first to discover angiogenesis switch inside blood vessel cells

...etermined to answer those questions. To do so they created laboratory conditions that would allow them to observe the two enzymes separately as they acted on the lipid. In a series of "in vitro" or laboratory experiments that controlled the presence of each enzyme, they began to understand the individual rol...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

Scientists have long been concerned about declining coral reef health off the southeastern Florida coast, in the Florida Keys and worldwide. The World Research Institute's Reefs at Risk program has listed coastal developme...

Sticky surfaces turn slippery with the flip of a molecular light switch

...searchers at Rensselaer Polytechnic Institute have created an "optically switchable" material that alters its surface characteristics when exposed to ultraviolet (UV) light. The new material, which is described in the June 19 issue of the journal Angewandte Chemie International Edition, could have a wide var...

New egg freezing technique offers hope to hundreds of women
