A cherry on top: Tart cherries may alter heart/diabetes factors

...ar Center. "These data from whole tart cherries join other findings that suggest a correlation between anthocyanin intake and reductions in cardiovascular and metabolic risk factors," he says. "But there is still a long way to go before we can advocate any course of action for humans. Still, the growin...

Lighting up life: Cold Spring Harbor Protocols presents tips for creating glowing plants

...udies in cell division. Both of these publications join a growing library of high-quality methods from Cold Spring Harbor Protocols that span a broad spectrum of topics essential to researchers across many disciplines. ...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

...es, we have developed a safer technique that could join other modalities as a treatment for breast and other cancers." ...

Gene found for rare disorder may reveal new pathway in mental retardation

...ound in classical CdLS, such as thin eyebrows that join together, long eyelashes, thin lips and excessive body hair. "In many of these patients, an experienced clinician might recognize their more subtle facial features as suggestive of CdLS, but for the most part, they would only come to clinical att...

Need oxygen? Cells know how to spend and save

... stations called cytochromes until they eventually join with oxygen to form water. This final step is directed by the protein cytochrome coxidase, or COX for short. If electrons react with oxygen before reaching COX, they generate "free radicals" that can damage or destroy cells. The mitochondria are des...

Are we killing the world's oceans?

...ut it? Members of the news media are invited to join leading international researchers and government decision-makers as they search for answers at a forum hosted by the University of Victoria on Feb. 21-22. The gathering, which is open to the public, will address scientific and policy issues of critic...

Notorious cancer gene may work by destroying messenger

...ges the properties of PMR1, and this enables it to join with, or bind to, its target mRNA. Peng then used monoclonal antibodies to isolate PMR1 and the enzyme while the two were bound together, capturing both. After separating the two, the investigators identified the enzyme as Src, which is a member ...

Nanotechnology shows promise as next wrinkle fighter

...Botox injections ? and nanoparticles are poised to join the war by warding off dreaded buckles in human skin. Ilsoon Lee, an assistant professor of chemical engineering, along with Ph.D. student Troy Hendricks, published an online article in the American Chemical Society's Nano Letters in December 2006 ...

Ring-around-the-cell

...says Geiger. "As soon as the music starts up, they join hands and form a tight circle. From afar, a circle of dancers looks like a blur, but now we have managed to make out the individual dancers." Addadi points out that, from above, isolated podosomes look like a tent with rope-like lines radiating fr...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

... must have its bond broken in order for the NTP to join the RNA chain through the formation of a phosphodiester bond, Kornberg said. The finding suggested the side chain acts as a trigger for bond formation. The whole decision-making process occurs extremely rapidly, he added, on the order of picosecond...

NHGRI aims to make DNA sequencing faster, more cost effective

... by ligation, a process where an enzyme is used to join pieces of DNA together. This phased award will increase if specific milestones are met in the initial experiments. Amit Meller, Ph.D., Boston University, Boston,$2.2 million (3 years),"High-Throughput DNA Sequencing Using Design Polymers and Nanop...

First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

....gov/ . Furthermore, the results are projected to join coral reef biological data from the NOAA PIFSC Coral Reef Ecosystem Division and National Centers for Coastal and Ocean Science, which will be placed in the Pacific regional NBII Pacific Basin Information Node and global Ocean Biogeographic Informati...

Regulating the nuclear architecture of the cell

... proteins known as histones; four similar histones join together to form a cylindrical spool around which the DNA wraps. Each of these bundles is called a nucleosome, and many nucleosomes are bound together by the continuing strand of DNA, which forms a string of beads that further coils to form one of tw...

Sandia researchers discover way to see how a drug attaches to a cell

...hed platinum structures - called dendrites - which join together in a network or cage in the shape of the ... "The resulting dendrites are then close enough to join and take the shape of the liposome. When the liposomes are broken up, the platinum spheres remain ...

Chemical tests of cell growth enter third dimension

...has worked out an initial design, he would like to join with a commercial microfluidics manufacturer to develop the technology further. The university is expecting to license both technologies. ...

Molecular mechanism provides intra-cellular traffic signal

... while at the other end of the Golgi, two subunits join TRAPP to activate the Ypt required for exit from the Golgi, Segev said. Segev said the mechanism that her lab identified must now be shown to exist in mammalian cells. Her earlier discovery of the Ypt molecular switches in yeast and the subsequent...

A new understanding of how cells defend themselves against bacterial pore-forming toxins

... or bits of bacterial flagellin. The inflammasomes join together and activate a protein, caspase-1, that in turn triggers an inflammatory response. Van der Goot and her colleagues found that in addition to its normal role as a signal for inflammatory response, caspase-1 also triggers the cell's central...

Singing for survival

...responded with his own song, before reappearing to join the group again. Because gibbons are unusually monogamous, it is thought that sexual selection is the main evolutionary mechanism for the evolution of gibbon song. The researchers concluded, "Vocal behaviour appears to function as a powerful too...

A giant among minnows: Giant danio can keep growing

...the muscle fibers, telling these cells to grow and join to adjacent muscle fiber to repair the injury. There is also an application to fish farming. “If we understood how fish grow, we could figure out strategies for enhancing the growth of farmed fish such as Atlantic salmon and decrease the time to ge...

Ocean temperature predicts spread of marine species

...drift far along ocean currents before returning to join adult populations. The distance larvae travel before maturing, called dispersal, is directly linked to ocean temperature, the researchers found. For example, larvae from the same species travel far less in warmer waters than in colder waters, said le...
