Storing carbon to combat global warming may cause other environmental problems, study suggests

...identity those tradeoffs and benefits at locations worldwide thought likely as places where land would be converted from other uses to tree plantations for carbon sequestration. Assessing the impact of existing conversions, the study showed that the larger water demands of growing trees rather than crops or p...

University of Arizona plant scientists to unravel maize genome

...nd, together with rice, accounts for 70 percent of worldwide food production. The production of corn-based products with enhanced nutritional value that are safer and less allergenic than the foods we eat today will directly benefit consumers. Corn plants will also prove useful in producing novel compounds, su...

Same-sex mating by fungi spawned infection outbreak, evidence suggests

...meningitis or death. While C. neoformans is found worldwide in association with pigeon droppings, the rarer C. gattii is normally restricted to tropical and subtropical areas, often in association with Eucalyptus trees. "It is suspected that the infectious propagules of Cryptococcus are airborne spores," Hei...

Health of coral reefs detected from orbit

...sat could potentially monitor impacted coral reefs worldwide on a twice-weekly basis. Coral bleaching happens when symbiotic algae living in symbiosis with living coral polyps (and providing them their distinctive colours) are expelled. The whitening coral may die with subsequent impacts on the reef ecosystem...

Recreating 'Flowers for Algernon' with a happy ending

...the drugs already prescribed to millions of people worldwide to lower cholesterol. "Steve raced into my lab and shared what he'd learned: statins work on the Ras protein that is altered by NF1 and play a key role in learning and memory," recalled Silva. "It was the researcher's equivalent of finding a sui...

When the work is complete, researchers worldwide will be able to query across the many individual research domains and projects, link to analysis applications, visualize data in a cell systems context and produce new knowledge. This will be accomplished while minimizing the effort, time and complex...

Feds give researchers ok for safety test of adult stem cells in patients with heart disease

...rtery bypass graft (CABG) surgeries were performed worldwide and approximately 1.8 million balloon angioplasty procedures were performed. While these interventional therapies are now the standard of care, there are still a significant number of people for whom these methods do not work, or who have blockage th...

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

...2002, Chamberlain and his colleagues embarked on a worldwide quest for feather and bone samples that would reveal the body chemistry of condors through the ages. "This work was fun," Chamberlain recalls. "First we got modern feathers from the Ventana Wildlife Society in Big Sur, Calif., and other groups involv...

NIH launches comprehensive effort to explore cancer genomics

...e Project, TCGA data will be made available to the worldwide research community. This data will provide researchers and clinicians with an early glimpse of what is hoped will evolve into an unprecedented, comprehensive "atlas" of information describing the genomes of all cancers. This atlas will enable researc...

Ancient humans brought bottle gourds to the Americas from Asia

...ottle gourds (Lagenaria sicereria) have been grown worldwide for thousands of years. The gourds have little food value but their strong, hard-shelled fruits were long prized as containers, musical instruments and fishing floats. This lightweight "container crop" would have been particularly useful to human soc...

Researchers develop new method to help find deadly malaria parasite's Achilles heel

...onsible for an estimated 1 million deaths per year worldwide from malaria has protein "wiring" that differs markedly from the cellular circuitry of other higher organisms, a finding which could lead to the development of antimalarial drugs that exploit that difference. The scientists will report in the Nov. 3...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...epatitis C virus. Approximately 200 million people worldwide suffer from chronic hepatitis C, which can persist in the body for decades after an initial infection, often causing so much liver damage that a transplant may be a patient's only chance for survival. The most effective treatment available, interfero...

Overfishing in inland waters reduces biodiversity and threatens health

Systematic overfishing of fresh waters occurs worldwide but is largely unrecognized because of weak reporting and because other pressures can obscure fishery declines, according to an article in the December 2005 issue of BioScience. Although the status of inland waters and their fish species should be o...
