World's tiniest test tubes get teensiest corks

...ic test tube shape, a problem Martin and his group solved in research published in 2004. To "cork" the test tubes in the latest research, the researchers applied an amino chemical group to the mouth of the tubes and an aldehyde chemical group to the corks. The two groups are complementary, so they bond with...

Leptin found to control appetite and limb development in frogs

...to successfully clone the frog gene. But once they solved those issues and put the gene into E. coli bacteria to make quantities of leptin, the frog protein turned out to be functionally very similar to the human version, Denver notes. "It would appear that leptin and its role as an energy balance indicato...

When it comes to gene transcription, random pauses arent quite so random, study finds

...rsity and the University of Wisconsin-Madison have solved part of puzzle. Writing in the June 16 edition of the journal Cell, the research team found that a molecule of RNAP makes frequent pauses at specific sites along the DNA double helix. This finding comes on the heels of the team's 2003 discovery that ...

Researchers discover which organs in Antarctic fish produce antifreeze

...fishes. This month three colleagues report they've solved the ensuing, long-running mystery of where these AFGPs, which allow the fish to survive in icy waters, are produced. "Ever since the discovery of these antifreeze proteins, it was assumed they had to be produced in the liver, since the vertebrate liv...

Delft water-purification method promises radical improvement

...ring bureau and supported by STOWA and STW grants solved various technological bottlenecks and expanded the capacity of the test installation from 3 litres per hour to 1,500 litres per hour. DHV now has the final design, which is ready for practical implementation. The aerobic granular sludge technology is...

ANU scientists crack DNA replication mystery

...een a long standing puzzle. The ANU team finally solved the important question of how TUS stops the replis...d the discovery was important "not just because it solved a fundamental scientific question, but also because TUS was found to lock onto the DNA very strongly...

U of I scientist develops enzyme inhibitor that may slow cancer growth

... Martha Ludwig's lab at the University of Michigan solved BMHT's crystal structure. "That breakthrough enabled us to look at the enzyme in three dimensions, which helped us design inhibitors for it. Several of those compounds were very effective in blocking binding of the enzyme's normal substrates," he s...

Molecular DNA switch found to be the same for all life

...of timely results," as Berger explained. "We had solved our initiator structures in the E.coli study just as results were being generated from the Botchan and Nogales groups on the Drosophila study. Once we compared notes, we immediately pooled forces. When we subsequently were able to dock our bacterial...

Structure determined for p53 tumor suppressor protein as bound to DNA for anti-cancer activity

...3 dimer that's compatible with DNA binding. And we solved the structure. We saw what it looked like." ...

Transmission rates of vCJD

...f governing equations of deformation, which can be solved in closed form for some isotropic and orthotropic conditions. It is shown that bi-stability depends on the change in Gaussian curvature of the shell, in particular, for initially untwisted shells, isotropy precludes bi-stability, where there is negat...

Snakes' virtual glasses, leopard spots and all-optical transistors

...t the Queen's University in Belfast appear to have solved the problems with a prototype optical amplifier that is both small and low power. The key to the device is a layer of gold film pierced by an array of holes 0.2 millionths of a meter in diameter and coated in a layer of polymer. The researchers shine...

Structure of key enzyme in plague bacterium found

... Institute of Standards and Technology (NIST) have solved the structure of a key enzyme from the bacterium responsible for plague, finding that it has a highly unusual configuration. The results may shed light both on how the bacterium kills and on fundamental cell signaling processes. The NIST team deter...

NASA announces media briefing about ocean plant growth

...carbon dioxide and the world's climate. This study solved the mystery why healthy looking ocean plants, or phytoplankton, are actually not so healthy. An article on this technique appears in the Aug. 31 issue of Nature. Reporters should call: 800-857-9091 and use the passcode "OCEAN" to participate in the...

NASA study solves ocean plant mystery

...ally under stress and unhealthy. These conclusions solved the mystery why healthy looking phytoplankton are actually not so healthy. "Because we didn't know about this effect of iron stress on the greenness of algae or phytoplankton before, we have always assumed that equally green waters were equally pro...

Workshop suggests turning problems into biofuels

...eedlot manure and too many mesquite trees could be solved by converting them into renewable bioenergy products, Texas A&M University System agricultural researchers, engineers and commercialization experts suggested Friday. The group met in a workshop following up the Texas A&M System energy conference, "...

Protein folding physics, nanohandles, sunscreen for algae and classical quantum weirdness

... supercomputers or large PC farms could instead be solved with individual desktop PCs running variational principle calculations. The researchers explain that the new application of the old physics method is faster because it allows them to spend less time calculating motions of molecules stuck in quasi-sta...

Study illuminates how the plague bacteria causes disease

...ort system. In the current study, the researchers solved the high-resolution crystal structure of a second YpkA domain, the "Rho-GTPase binding domain" along with the host protein, "Rac1," with which it interacts. "The Yersinia structure was doing things to Rac1 that the host proteins normally do," Stebbi...

'Crabby' compound that skewers bacteria could prevent medical implant infections

...ing to Stewart. "I don't want to claim we've fully solved the problem here," he said, "but I think over the next 10 years we're going to be seeing new technologies in the form of coatings that will prevent or at least reduce the incidence of infection." Chitosan is derived from chitin, the main component...
