Protecting endangered species helps reduce poverty

...agement of species and their habitats means better protection of forest, freshwater and marine habitats. As a result, the rural poor who depend on these areas have more access to the goods and services they provide. Incomes increase and access to freshwater, health, education and women's rights often also impro...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...strated that the hybrid antibodies provide instant protection against the vaccinia virus and likely smallpox and are potentially more potent and more specific than the treatment we currently have available," says Dr. Purcell. The hybrid antibodies also offer a potentially significant advantage over VIG as a tre...

Driver of anthrax toxicity could lead to late-stage therapy

...ational Institutes of Health. The level of anthrax protection afforded by the antibodies rose with increasing dose. Anthrax is a lethal disease of humans and other animals caused by the spore-forming bacteria Bacillus anthracis, which has been the focus of biological interest and bioterrorism concern. The viru...

Mute swan population helps explain longstanding evolutionary question

... relaxation of food constraints and an increase in protection from predators may have helped enable the swans to evolve towards a new, larger clutch size. ...

Satellites show Amazon parks, indigenous reserves stop forest clearing

...of the Brazilian Amazon ?five times the area under protection in parks ?and are currently the most important barrier to Amazon deforestation. Some conservationists argue that with acculturation to market society, indigenous peoples will cease to protect forests. But the authors found that virtually all indigen...

Pitt professor's theory of evolution gets boost from cell research

...n the cell, and so on. In short, with that kind of protection from change, it is very difficult for mutations, of whatever kind, to gain a foothold. But extreme stress pushes cells beyond their capacity to produce protective proteins, and then mutation can occur. This revelation has enormous implications for t...

Researchers map of genetic variations implicated in disease

...t common human haplotypes, selected for conferring protection against or susceptibility to common disease. The d... and myasthenia gravis. The PGF haplotype provides protection against type 1 diabetes and predisposes to other diseases such as multiple sclerosis and systemic lu...

New male contraceptive clears hurdle

...al contraceptive that provides 10 or more years of protection after a 10-15 minute procedure. Researchers received approval this week to begin enrolling additional study volunteers, after a delay of nearly four years. "RISUG would be exciting because it would mean that, finally, I could take control of my own ...

Birth defects: 8 million annually worldwide

... a gene for an inherited disease that confers some protection against malaria -- specifically, sickle cell, thalassemia, and glucose-6-phosphate dehydrogenase deficiency (G6PD). When two carriers of these diseases have offspring, there is a 25 percent chance that each child will receive both copies of the gene...

Human trial proves ricin vaccine safe, induces neutralizing antibodies; further tests planned

...ne and a collaborator on the study. Based on the protection they observed in the mice injected with ricin mixed with human-produced antibodies, the researchers projected that a RiVax-vaccinated human could withstand a lethal dose of injected ricin. According to the Centers for Disease Control and Prevention, ...

Engineers discover why toucan beaks are models of lightweight strength

.... "Panels that mimic toucan beaks may offer better protection to motorists involved in crashes." Toucans are highly social, noisy residents of rainforests in the Amazon, although the birds live as far north as Mexico. They use their extremely large and often brightly colored beaks for a variety of purposes, f...

Overfishing in inland waters reduces biodiversity and threatens health

...ainability of yields, maintenance of biodiversity, protection from habitat degradation and other anthropogenic stressors, and provision of socioeconomic benefits to a broad spectrum of consumers. ...

Scientists directly view immune cells interacting to avert autoimmunity

'Good' bacteria could save patients from infection infection by deadlier ones

...pital environment, thus creating a kind of natural protection against the deadlier strains. To test his hypothesis, Spigelman suggests experimenting with antibiotic-free hospitals in which harmless bacteria would be free to exist and there would be no environmental "incentive" for the more virulent strains to...

New research examines genetics of successful aging

...group of young adults. These gene variants confer protection and risk, respectively, of Alzheimer's disease, the most common cause of dementia in late life. The study also identified novel genetic regions associated with successful aging, including DYS389 and DYS390, some of which affected men or women, but n...

Overfishing may drive endangered seabird to rely upon lower quality food

...relet from the Endangered Species list, denying it protection even though the bird has not recovered throughout its range. The researchers argue that such a move would be premature. "The threats that have caused marbled murrelets to decline throughout their range have not been remedied," said Beissinger. "Coas...

Polio vaccination strategies assessed as eradication nears

...tially protected from spread of poliovirus. Better protection may be achieved by enhancing IPV further, they said. However, an accompanying editorial by Harry F. Hull, MD, and Philip D. Minor, MD, at the Minnesota Department of Health and the U.K. National Institute for Biological Standards and Control noted ...

Envisat radar surveillance protects endangered prehistoric fish

New technique multiplies life span in simple organisms

...of reproduction, improved DNA repair and increased protection against cell damage. Organisms usually enter this mode in response to starvation. The long-lived organisms in Longo's experiment showed extraordinary resilience under stress. "We hit them with oxidants, we hit them with heat," Longo said. "They are...

First big influenza genome study reveals flu evolution

... explains why the 2003-04 flu vaccine offered less protection than usual. Every flu season, a global network of scientists attempts to identify several predominant flu strains and factor them into the next season's flu vaccine. Predictions are tricky, however, because influenza is constantly changing. In the ...
