CU, USDA team to curb two invasive, poisonous vines

...rath, a USDA-ARS research entomologist at Cornell, adding that introducing any agent will require federal approval. "Our research will help guide the selection of an effective agent." Milbrath, whose funding from USDA supports the Cornell collaboration on a three-year project, is working with researchers a...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

... animal's geographic location, and researchers are adding new capabilities to the tags, such as measuring the chlorophyll content of the water (an indicator of algal blooms or "primary productivity"). "We can now use animals to show us things like the thermal properties and cooling rates of the ocean and ...

Infections could contribute to adult brain tumours

... pattern typical of diseases caused by infections, adding weight to the theory that outbreaks of viruses are a potential contributory cause of brain tumours. Diseases caused by more constant environmental factors, such as pollution, produce clusters of cases in one place over a much longer time period. Ho...

Invasive species harms native hardwoods by killing soil fungus

...pressed tree growth. Other experiments showed that adding garlic mustard extracts to soil impaired AMF colonization and seedling growth, implying that the weed uses phytochemical poisons to disrupt native plants' mycorrhizal associations and stunt their growth. When the study was subsequently replicated w...

Marine mammals are on the frontline of failing ocean health

...an effect on the spread of disease and pollutants, adding yet another twist to the story. Jim Berner, an MD with Alaska Native Tribal Health Consortium, works in northern ocean ecosystems, where climate change is having a marked effect. "Alaska is a laboratory for human health issues, particularly those t...

'Uniquely human' component of language found in gregarious birds

...e songs were built up from a rattle-warble base by adding rattle-warble pairs at the end. The simplest song (ab) was one rattle followed by one warble. The next simplest a rattle, then a warble, followed by a different Rattle and Warble (abAB). The other eight songs followed the "context-free" rule, whic...

Researchers reverse juvenile diabetes in animal model

....e. peptides) of insulin. Dr. Trucco believes that adding small doses of insulin to the dendritic cells will help guide the dendritic cells directly to the T cells. Adding the insulin ensures the dendritic cells are used specifically to block the T cell destruction of the beta cells, and not otherwise inter...

H5N1 avian flu virus vaccine induces immune responses in healthy adults

...at may allow us to reduce the dosage--for example, adding an immune booster, or adjuvant, to the vaccine--so we can achieve a more practical immunization strategy." In addition, the U.S. Department of Health and Human Services is pursuing other approaches to an H5N1 vaccine, including vaccines made in cell ...

Clawed frog helps Fanconi anemia research make leaps

.... Then, by chemically activating the extract and adding sperm DNA from the male frog, the proteins in the ...rawn to the DNA once the copying process began. By adding a protein called geminin to the extract, which prevents the assembly of protein complexes essential ...

Duke to test bird flu vaccine dosing

... and Baylor College of Medicine. "We hope that by adding a compound called an adjuvant to the vaccine, we can create a stronger immune response to smaller doses of the vaccine," said Emmanuel Walter, M.D., associate director of the Duke Clinical Research Institute's Primary Care Research Consortium and lea...

HIV/AIDS rates in Tijuana, Mexico increasing at alarming rate

...tween Tijuana and San Diego County," said Brouwer, adding that high-risk groups ?men who have sex with men, injection drugs users, sex workers and pregnant women ?are of particular concern. The aim of the UCSD study, conducted along with collaborators in Mexico, was to estimate the number of men and women ...

Stem cells from muscles can repair cartilage

... of BMP-4 protein to the injury site," they state, adding that the improved repair lasted for 24 weeks following transplantation. Further studies conducted by the authors (not yet published) have produced similar results. They conclude: "These findings suggest that BMP-4 gene therapy based on retrovirally t...

Yale scientists decipher 'wiring pattern' of cell signaling networks

...lator switches and modify their target proteins by adding a phosphate group to them. This process, called "phosphorylation," results in altered activity of the phosphorylated protein. It is estimated that 30% of all proteins are regulated by this process. Using technology developed in Snyder's laboratory,...

Engineers discover why toucan beaks are models of lightweight strength

Sooner is better with cochlear implants, Stanford scientist shows

...ceived their implants before the age of 30 months, adding to the body of evidence suggesting that the earlier a hearing-impaired child receives a cochlear implant, the better. "I see this as a fascinating experiment that reveals the tremendous capacity for plasticity in the developing brain," said Eric Knu...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

...d to changes taking place during an experiment -- adding a chemical or changing the temperature, for instance. This aspect of the method provides scientists with the specificity they need to weed out such introduced gene activation from fundamental gene activation pathways that form the hallmark of process...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

...8th century and the modern era," Chamberlain says, adding that both events coincide with the arrival of humans in North America. "During the Pleistocene, condors were distributed across the continent," he explains. "There was plenty of megafauna to feed on, including mammoths, mastodons, camels and bison."...

What can change in the brain? Electrical synapses, research shows

...hening or weakening connections between neurons or adding or subtracting those connections - allows it to form memories, make transitions between sleep and waking, and focus attention on objects of interest. This phenomenon is a form of neural plasticity. Chemical synapses, junctions where neurons communic...

Sahara's edge studied from ground, air and space to improve water management

...T-based training sessions on the processing, value adding and use of the AquiferEx data are planned for 2006 in the Aquifer framework. As with similar campaigns, the results from AquiferEx ?which are superior in geometric resolution and the number of channels or polarisations to the capability of presentl...
