Squid-inspired design could mean better handling of underwater vehicles

...r cephalopods, a University of Colorado at Boulder researcher has designed a new generation of compact vortex generators that could make it easier for scientists to maneuver and dock underwater vehicles at low speeds and with greater precision. In addition, the technology - seemingly inspired by the plots of t...

Hope for a more effective and less toxic cancer drug

...kill the unwanted cells on cue. WEHI's leading researcher with the assessment project, Dr David Huang, explains, "Normally, the cell death machinery is switched on when damaged cells need to be removed. The failure of the machinery to be turned on when it should can lead to cancer. ABT-737 is a 'switch flic...

Poor athletic performance linked to vitamin deficiency

...fficiently and fight disease, said Melinda Manore, researcher in the Colleges of Agricultural and Health and Human Sciences. Manore analyzed the athletic performance of several elite and collegiate athletes in her research, as well as less competitive individuals. The stress on the body's energy producing pat...

Research holds promise for herpes vaccine

A study by a Montana State University researcher suggests a new avenue for developing a vaccine against genital herpes and other diseases caused by herpes simplex viruses. In a study published earlier this year in the Virology Journal, MSU virologist William Halford showed that mice vaccinated wi...

Nanotech tools yield DNA transcription breakthrough

Rutgers researcher Richard H. Ebright and his collaborators have resolved key questions regarding transcription, the fundamental life process that was the subject of the 2006 Nobel Prize in Chemistry. Transcription is the first step in the process cells employ to rea...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...pact," said Dr. Gerald A. Tuskan, ORNL and DOE JGI researcher and lead author of the SCIENCE study. "Biofuels emit fewer pollutants than fossil fuels such as gasoline. In addition, poplar and related plants are vital managers of atmospheric carbon. Trees store captured carbon dioxide in their leaves, branche...

Brain regions do not communicate efficiently in adults with autism

...ortex, according to Michael Murias, a postdoctoral researcher who headed the study. "Our findings indicate adults with autism show differences in coordinated neural activity," said Murias, "which implies poor internal communication between the parts of the brain." The UW researchers analyzed EEGs from...

'Tribbles' protein implicated in common and aggressive form of leukemia

...100 new cases reported each year. Pear, also a researcher in the Abramson Family Cancer Research Institute at Penn; first author and postdoctoral fellow Karen Keeshan, PhD; and colleagues found Tribbles by chance when looking for the molecular partners of another protein called Notch. Notch is a molecular s...

Wild tigers need cat food

Scientists discover role for dueling RNAs

...ommon baker's yeast, Cintia Hongay, a postdoctoral researcher in the lab of Whitehead Member and MIT Professor Gerald Fink, discovered that in the case of a gene called IME4, the antisense RNA blocks the sense RNA. In other words, the gene disables its own ability to make protein. "This is the first case wh...

Researchers image molecular motor structural changes

...computer image processing. Keiko Hirose, Ph.D., a researcher at Japan's National Institute of Advanced Industrial Science and Technology, performed the elaborate and time-consuming electron microscope imaging. She carefully made multiple images of the kinesin-microtubule units, and performed the computationall...

Boston University biomedical engineers win major grant for pursuit of the '$1,000 Genome'

...y increase the process' resolution. He is the only researcher in the world using this method, which he names "Opti-Pore." Weng's involvement centers on bioinformatics ?using computational methods to organize the large amount of data collected. Meller said he is grateful for the grant, which validates his ap...

Scientists get best look ever at water-life connection

... Zhong began to develop when he was a postdoctoral researcher in Nobel laureate Ahmed Zewail's lab at the California Institute of Technology 5 years ago. Laser studies of the protein while it was immersed in water revealed that far away from the protein -- in a region Zhong called "bulk water" -- the water mol...

Beyond the book: Software automates access to brain atlases

...umber of page images in an organized fashion. A researcher working with her own set of images ?typically taken from a set of brain sections ?can, working back and forth from the software, integrate them with atlas pages, once the exact brain location of the section has been recognized. To do this, she superi...

Mayo Clinic: Gene expression profiling not quite perfected in predicting lung cancer prognosis

...h Sciences Research at Mayo Clinic. Dr. Yang, a researcher with Mayo Clinic's Department of Health Sciences, said that while gene expression profiling has been successfully used to classify various tumors and assess tumor stage, metastasis and patient survival rates, the evidence suggests that gene-based pre...

UCSD researchers discover internal compass of immune cell

.... Lead authors Yu Chen, M.D., UCSD postgraduate researcher in surgery and Ross Corriden, UCSD graduate student in biomedical sciences, found that when ATP receptors were blocked, the cells became disoriented, while blocking A3 adenosine receptors slowed down the cell movement toward chemoattractants. The re...

Soil nutrition affects carbon sequestration in forests

...pheric CO2 concentrations," says Kurt Johnsen, SRS researcher involved in the project. "With lower soil nutrition, forests still sequester carbon, but cannot take full advantage increasing CO2 levels. Due to land use history, many forests are deficient in soil nutrition, but forest management -- including ferti...

A natural chemical found in strawberries boosts memory in healthy mice

...s memory," says lead author Pamela Maher, Ph.D., a researcher in the Cellular Neurobiology Laboratory at the Salk Institute. Maher hit upon the beneficial effects of fisetin when she screened a collection of flavonoids, substances with anti-oxidant activities found in many plants, for their neuroprotective a...
