Knowledge of infection may prevent spread of herpes virus

... Carolina at Chapel Hill as one of three effective tools to prevent the spread of this sexually transmitted disease (STD). "Genital herpes is one of the few common STDs for which, at present, there is little coordinated emphasis on control efforts," say Hook and Leone. The two experts also support suppre...

UC San Diego biologists solve plant growth hormone enigma

...or a long time, but only recently have new genetic tools such as 'reverse genetics' and 'activation tagging' made it possible," explained Youfa Cheng, a postdoctoral fellow working with Zhao. "Even with the advances in technology, it took about three years to produce plants lacking at least four of the 11...

Iron critical to ocean productivity, carbon uptake

...te data record is too short. "But now we have the tools to determine that," he emphasized. The northern portion of the tropical Pacific is more nitrogen-stressed and doesn't have the "false greenness," according to Behrenfeld. The researchers are creating new models of carbon cycling using NASA satellit...

Study finds how organs monitor themselves during early development

...he ovary does this." There were no experimental tools to let her study the entire process. She needed to be able to test many genes, many conditions, and find markers of those conditions so the results would be visible under the microscope every step of the way. Over several years, Dr. Gilboa developed ...

UF scientists discover evolutionary origin of fins, limbs

... the body, intuitively one would think the genetic tools for fin development would be brought together in that place," said developmental biologist Martin Cohn, Ph.D., an associate professor with the UF departments of zoology and anatomy and cell biology and a member of the UF Genetics Institute. "We've di...

A more powerful and efficient engine for rice: the C3-C4 challenge

...l consortium of scientists will have assembled the tools and materials to begin constructing the prototypes of a C4 rice plant. It will be another 10?5 years after that before the first varieties are available. "Considering the urgent rice production challenges we face, we must start now on this work--t...

Mitochondrial DNA sequencing tool updated

...ell nucleus, scientists lacked the needed research tools throughout most of the 20th century to systematica...iguous genes. But because of the balky sequencing tools of the day and their high cost, much of the subsequent research progressed slowly or stalled. By 1...

Genes discovered that allow gum disease bacterium to invade arteries

... to the development of therapeutics and diagnostic tools for the detection and possibly prevention of heart diseases caused by this association." ...

RNA interference stops colon cancer spread in mice

Using one of the newest and most powerful tools of biomedical science, University of Texas Medical Branch at Galveston (UTMB) researchers have scored a dramatic success in the battle against colorectal cancer. The scientists were the first to use what are known as "small interfering RNAs" to bloc...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...pel harmful bacteria from the surfaces of surgical tools like catheters. Finally, the method also offers a simple method to genetically modify cells. "This is not the end of the story, but the beginning," says Brinker. "No one else has created these symbiotic materials and observed these effects. It's ...

Long-term changes in experience cause neurons to sprout new long-lasting connections

...he world who are pioneering the development of new tools and techniques that permit scientists to observe the brain as it rewires over a period of weeks or months. This summer Svoboda will move to HHMI's Janelia Farm Research Campus where he will pursue neurobiology studies and projects in optics and micro...

NHGRI announces latest sequencing targets

...his effort will allow researchers to develop basic tools to better understand human variation, such as distinguishing functional from non-functional variations within genes. A final set of sequencing targets was chosen to address the question: What genes and other genomic features were respo...

Connect the Quantum Dots

...and spectroscopy have become invaluable analytical tools in biomedical research but rely on the fluorescence of organic dyes which have limited luminescent properties. Quantum dots have superior photophysical properties and will presumably replace conventional organic dyes in biomedical applications. The...

Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate

...ct the development of virally delivered biocontrol tools for insects that transmit pathogens to humans or harm agriculture. It might also enable the design of alternative therapies for debilitating illnesses such as river blindness and elephantiasis, whose pathologies are caused by Wolbachia bacteria livin...

Heal thyself: Systems biology model reveals how cells avoid becoming cancerous

...nteractions was made possible by new biotechnology tools that provide comprehensive analysis of cells, like a passerby suddenly being able to monitor all the telephone calls made within a city. The team discovered that part of the interaction network was involved, as expected, in repairing damaged DNA. Ho...

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

...s have been unable to "see" the protein ?using the tools of structural biology ?bound to DNA in its naturally occurring form. This naturally occurring form contains a pairing of two p53 proteins, called a dimer, that then binds to a second p53 dimer in a similar way to create the precisely oriented four-pr...

A new look at the state of the oceans

...r species identification. In many regions, genetic tools have revealed that species diversity is much higher than previously thought. Especially in marine systems, the term 'diversity' not only describes the distinction between biological species, but also refers to the divergence within established specie...

New strategy rapidly identifies cancer targets

...finding much," he said. Instead, the team added tools from the burgeoning field of proteomics, the study of proteins. "We decided this more functional assay would get us to the disease-causing genes more rapidly," said Druker, who has been studying a group of cell-signaling proteins called tyrosine kina...

What's nature worth? New computer models tell all

... his team will create a set of computer models and tools that will give a sophisticated portrait of the ecosystem dynamics and value for any spot on earth. "Land use planners, county commissioners, investment bankers, anyone who is interested," Cosntanza said, "will be able to go on the Web, use our new ...
