Increase in carbon dioxide emissions accelerating

...aupach says. He says this indicates that recent efforts globally to reduce emissions have had little impact on emissions growth. "Recent emissions seem to be near the high end of the fossil fuel use scenarios used by the Intergovernmental Panel on Climate Change (IPCC). On our current path, it will be dif...

Fire ant-attacking fly spreading rapidly in Texas

... cannot adapt. That's why we are focusing research efforts in parts of Argentina that look exactly like the South Texas brush country." Gilbert is also working with ranchers to help them learn how to infest their own fire ant colonies with phorid flies. He began the initiative in 2005 with ranchers from Be...

UGA scientists engineer root-knot nematode resistance

...matode resistance," Hussey said. The researchers' efforts have been directed primarily at understanding the molecular tools the nematode uses to infect plants. This is a prerequisite for bioengineering durable resistance to these nematodes in crop plants. Through this research, they've discovered the paras...

African wetland managers armed with new technology

...n-situ monitoring networks hinder the conservation efforts of wetland managers and water authorities. In support of all African countries participating in the project, GlobWetland ?which is funded by ESA's Data User Element (DUE) ?hosted a five-day training seminar, developed jointly by Wetlands Internatio...

Mouse study reveals new clues about virulence of 1918 influenza virus

...enza pandemic is an urgent imperative as we pursue efforts to prepare for--and possibly thwart--the next flu pandemic," says NIH Director Elias A. Zerhouni, M.D. "This elegant research gives a detailed picture of the overzealous host reaction to infection by a fully reconstructed 1918 influenza virus," sa...

Vaccine shown effective against chancroid

...a, according to the World Health Organization, and efforts to develop a vaccine against the virus have achieved limited success. But what if a vaccine against another sexually transmitted infection found widely in that region of Africa ?chancroid ?was relatively easy to develop and could reduce transmission ...

Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs

...a new Colombian protected area the focal point for efforts to save amphibians from a deadly fungus decimating their populations in Central and South America. Scientists recently found the two Critically Endangered frogs ?the Santa Marta harlequin frog (Atelopus laetissimus) and the San Lorenzo harlequin fro...

Evolutionary forces explain why women live longer than men

Despite research efforts to find modern factors that would explain the different life expectancies of men and women, the gap is actually ancient and universal, according to University of Michigan researchers. "Women live longer in almost every country, and the sex differenc...

Potato blight pathogenicity explained by genome plasticity

All the eggs in one basket

...y Jackson and Marah Newman agree that conservation efforts since the 1970's have dramatically helped increase green and hawksbill turtle populations that nest on protected beaches. However, they argue that dwindling turtle populations on many historically important nesting beaches are overlooked by conserva...

Major initiative proposed to address amphibian crisis

Tigers get a business plan

... initiative. "I am most interested in supporting efforts that will get results," said Cline. "WCS's Tiger's Forever initiative has brought together two key initiatives ?superb people armed with an understanding of what it takes to save tigers. In an area where there have been many disappointments, I am b...

Microbes transform 'safest' PBDEs into more harmful compounds

...y, suggests these transformations could complicate efforts to reduce or eliminate the most problematic polybrominated diphenyl esters (PBDEs) from the environment. "This study, for the first time, establishes that microbes found in every-day settings can degrade relatively stable forms of PBDEs, making them...

Plant protection from cold decoded

...S1 acts on plants should help his overall research efforts into how plants respond to environmental stresses such as cold, soil salinity and drought. "From a genetic and molecular standpoint, these responses are all related," Zhu said. "Some of the same genes are involved in all of these responses and under...

Agriculture and tropical conservation: rethinking old ideas

...les that rural peasant activities are at odds with efforts to preserve biodiversity in the tropics. In fact, the opposite is often true, argue University of Michigan researchers John Vandermeer and Ivette Perfecto. Combining case studies with ecological theory, Vandermeer and Perfecto found that the peasa...

Colombian frog believed extinct found alive

... most diverse on Earth and key in the conservation efforts to protect amphibian species worldwide. So far, 42 of the 113 species of Atelopus found in the Tropical Andes Hotspot that includes parts of Colombia, Ecuador, Peru and Venezuela have experienced population declines of up to 50 percent. Frogs provid...

Structure determined for p53 tumor suppressor protein as bound to DNA for anti-cancer activity

...A, the challenge for the scientists was that their efforts to crystallize the p53 dimer bound to DNA consistently resulted in structures that could not bind to DNA. (Crystallization is a prerequisite for obtaining the type of three-dimensional image sought in this study.) The researchers found that the dimer...

HIV infection requires an accomplice: B cells with special protein direct HIV to T cells

...plications for future studies and drug development efforts that focus on reservoirs of HIV in cells other than T cells," said Charles R. Rinaldo, Jr., Ph.D., professor and chairman of the department of infectious diseases and microbiology at Pitt's Graduate School of Public Health (GSPH) and the study's seni...

Heart has enough oxygen to survive hypothermia, CPR crucial
