Air travel and pandemic flu

... themselves be harmful. If they are not effective, resources could be wasted on enforcing them. Researchers of the Centre for Infections, Health Protection Agency, UK used the techniques of mathematical modelling. In other words, complex calculations were done using information that is already available abou...

How the US drug safety system should be changed

...ncy and industry. It also needs substantially more resources for the postmarketing study of drug safety. Strom concludes by proposing that an independent, nongovernmental organization is needed for nonregulatory tasks that are not within the mission of the FDA. Since many of these tasks are academic in nature...

New strategy developed to combat West Nile Virus

...rought occurs early in the year, the limited water resources confine mosquito populations to selected habitats ?specifically isolated, densely vegetated hammocks where conditions remain humid. These moist hammocks also happen to be the spring nesting and roosting sites of many species of wild birds, which act...

NAU researchers chirping over discovery of new cricket genus

...elevant to the management and conservation of cave resources on the monument," Wynne said. Crickets provide a valuable ecological service to the environment. Some species are often the primary decomposers in cave ecosystems. The researchers also found a new cricket species (genus Ceuthophilus), possibly tw...

Evolutionary forces explain why women live longer than men

...y and behavior for the males, such as putting more resources into flashy plumage or engaging in physical sparring. And even in modern life, where most dueling is a form of entertainment, male behavior and physiology is shortening their lifespans relative to women, Kruger said. In fact, modern lifestyles are a...

Potato blight pathogenicity explained by genome plasticity

...y genetic modification, may be a waste of time and resources when the genome dynamics of the pathogen population is not understood," says Govers. "Monitoring field populations of plant pathogens at the genome level will be instrumental for predicting the durability of R genes in crop plants." ...

How bad is malaria anemia? It may depend on your genes

...in places where malaria is endemic, drug treatment resources are scarce," says the study's primary author, Michael A. McDevitt, M.D., Ph.D., an assistant professor of medicine and hematology at the Johns Hopkins School of Medicine. "There are many difficulties with blood transfusion safety and access in Afri...

DNA to the defense

... as a master of adaptation, devoting unprecedented resources to avoiding immune attack. Since the VSG coat appears to prevent access to other non-variable parasite proteins, such capacity for variation further dims hopes for an effective vaccine for affected populations in rural Africa. ...

DOE publishes research roadmap for developing cleaner fuels

... Karsner said. "We fully intend to use all of our resources and talent to support the President's goal of breaking our addiction to oil, while also enhancing our energy security." ...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

...ving researchers access from their own desktops to resources held on widely-dispersed computers, it is enabling research that would have been impossible using one computer alone, even a supercomputer. The projects that will pioneer new research using e-Science are: Understanding the brain The £4.5m CARMEN...

Hope I die before I get old?

...iness results more from their underlying emotional resources -- resources that appear to grow with age. People get better at managing life's ups and downs, and the result is ...

Researchers appeal for new regulations to save coral reefs from live fish trade

...or tighter regulations on the exploitation of reef resources which are particularly important to developing tro...arises from the export of the dwindling coral reef resources of developing tropical nations. "Once those resources are destroyed and forgotten, it is the local...

UGA researchers find that hunting can increase the severity of wildlife disease epidemics

... is reduced, those that survive are left with more resources such as food and shelter. As a result of the newly plentiful resources, the death rate decreases and the birth rate increases, compensating ?and sometimes overcompensating ?for the loss. Killing wild animals can also increase the proportion of the ...

Agriculture and tropical conservation: rethinking old ideas

... Vandermeer and Perfecto, a professor of natural resources and environment, visited agroforests in the Pontal de Paranapanema region of Brazil, where landless peasants organized by Catholic priests established homesteads in the 1950s and 1960s. There, the researchers saw evidence that the farms do indeed ser...

UN review shows need to halt destructive fishing practice

... protection, but that fishing for newly discovered resources in the high seas often proceeds unregulated to the point of serious harm. "Many fisheries are not managed until they are overexploited and clearly depleted and,because of the high vulnerability of deep-sea species to exploitation and their low pote...

New light microscope sharpens scientists' focus

...was ready for testing, thanks in part to equipment resources marshaled by the NICHD. Additional financial resources supplied by HHMI ensured that the work would be well funded in the future since Betzig, at almost th...

Even a little cooling helps after cardiac arrest

...dicted." Hechinger hopes to produce a manual for resources managers that will explain how to collect snails, identify the trematodes inside them, and then translate this information into information on resident populations of birds, fishes and benthic invertebrates. "We think counting trematodes is an effec...

NHGRI announces latest sequencing targets

...cts are designed to use high-throughput sequencing resources to lead to significant medical advances. As more is learned from sequencing and other studies about the genomic contribution to disease, and as the cost of obtaining sequence information decreases, genomic sequence information will become ever more i...
