B-15A collides with Antarctic ice tongue

...t arrays far more valuable." This announcement is being made in conjunction with the extensive release of microarray experimental data into the public domain by the National Toxicology Program. Icoria Inc., under its contract with the National Institute of Environmental Health Sciences (NIEHS), has been u...

Undesirable expatriates: Preventing the spread of invasive animals

...to combat invasive species is to prevent them from being introduced. As global trade increases, precautions like port inspection and exotic wildlife regulations are essential. Consumers also need to be educated; many exotic animals that are legal as pets could be ecologically lethal if released into the wi...

Plant Sacrifices Cells to Fight Invaders

...s for the field of plant research and is currently being used by several research groups. NSF's Jane Silverthorne said, "This is a great example of how NSF-supported tools are enabling important basic research in plants with a broader relevance to other organisms." ...

Scientists discover that three overlapping signals in embryo help get the backbone right

...tant step that you actually have multiple proteins being expressed there, just in case one of them fails, the others can compensate," said lead author Mustafa Khokha (pronounced KO' ka), a post-doctoral fellow at UC Berkeley and an attending physician in pediatric critical care at UC San Francisco. "Redund...

NIAID begins clinical trial of West Nile virus vaccine

... the VRC against HIV/AIDS, Ebola and SARS also are being tested in ongoing trials at NIH. Fifteen healthy volunteers between the ages of 18 and 50 will receive three injections of the DNA vaccine into the upper arm: one at the start of the trial, a second approximately four weeks later, and a third approx...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...han 20 years ago, Nottebohm discovered new neurons being born in adult birds, overturning the conventional wisdom that all neurons in vertebrates are created by birth or soon after. In the new study, the researchers looked at cells in the high vocal center region of the brains of 19 zebra finches, a kind ...

Doctors closer to using gene analysis to help trauma patients

... able to get the same answers wherever the tool is being used.?/p> Genomic analyses took place at UF, the Stanford Genome Technology Center and Washington University in St. Louis. Overall data analysis was based at Massachusetts General Hospital at Harvard Medical School. Specially trained clinical pe...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

... aspect in all of these, he says. The most obvious being when conditions in the home river are so degraded that salmon move elsewhere to spawn. Straying is just one of the traits that cause Quinn to say that salmon have chances to recover from years of declines "if we would only take our collective foot o...

Putting ecology back into river restoration

...ogically successful river restoration. The plan is being led by the British Ecological Society's Journal of Applied Ecology, which this month is publishing a special profile on river restoration. Opening the debate is a paper by 22 leading US river ecologists proposing five criteria for ecologically succes...

Taking the piste out of Alpine vegetation

...tes, with woody plants and early-flowering species being most badly affected. Machine grading of ski slopes caused most damage to vegetation, with machine-graded slopes having five times more bare ground than ungraded pistes. And, say the researchers, this damage is long lasting. They found pistes that ha...

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...s of beginning therapy. In two different studies being presented at the annual meeting of the American Association for Cancer Research (AACR), the research team will describe how the test measures the activity of several members of the cyclin-dependent kinase (CDK) family of enzymes, which are the trigge...

Confocal imaging promises early detection of skin cancer

...s to detect and diagnose skin cancer, the simplest being a magnifying glass. Most techniques evaluate external skin features, such as colour or morphology. “But doctors need to look deeper into the basal layers, at least one millimetre down, to be sure of their diagnosis,?says Dr Sheblee. The original ide...

The lopsided brain: Attention bias is shared by humans and birds

The researchers include Bettina Diekamp and Onur Güntürkün of the Ruhr-Universität Bochum, Germany; Lucia Regolin of University of Padova, Italy; and Giorgio Vallortigara of the University of Trieste, Italy. Bettina Diekamp,...

Findings have implications for tracking disease, drugs at the molecular level

...cts of this technique is that it paves the way for being able to observe behavior in living tissues at the single molecule level," said Fourkas. "The fluorescent molecules commonly used in multiphoton imaging give out only a limited amount of light, 'burn out' quickly under continuous observation, and are ...

Study uncovers bacteria's worst enemy

In addition to Neu, the bacteria bioremediation study team includes Christy Rugg...

Cellular Defects in Premature Aging Disease are Reversible

...oblems. The condition is fatal, with heart disease being the leading killer, and affected children usually die before they reach their late teens. Less than two years ago, NIH-led researchers discovered that the genetic basis for HGPS is a single mutation in the gene encoding lamin A. Lamin A is a critica...

Basis for DNA ejection from single phage particles

... at different stages of the ejection process after being stretched by applied hydrodynamic flow. The study demonstrated that DNA release is not an all-or-none process, but rather is unexpectedly complex. DNA release occurred at a very high rate, reaching 75,000 base pairs of DNA/sec, but in a stepwise fash...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

...olecules that biochemists believe to be capable of being molecular switches but that have failed to exhibit those properties in conductance experiments. The team solved the problem by developing a technique where the molecule could be tested in an electrolyte solution, a condition that past experiments did...

Science study holds implications for gene therapy and stem cell biology
