Small, smaller, smallest -- The plight of the vaquita

...es and northern elephant seals, both of which came back from low numbers and now represent true conservation success stories. Similar efforts are needed urgently for the vaquita, a small animal living in a small area with a small, and ever-smaller, population....

Evolution and the workaround

...e for Medical Research in Kansas City, MO, to step back and consider the basic process by which cells adapt to the loss of seemingly irreplaceable genes. The researchers reasoned that understanding how cells adapt to internal perturbations could offer insight into how pathogens and cancer cells mutate to...

Giant insects might reign if only there was more oxygen in the air

...too? After all, dragonflies and some other insects back then had the same body architecture, but they were much bigger. It is because when the oxygen concentration in the atmosphere is high, the insect needs smaller quantities of air to meet its oxygen demands. The tracheal diameter can be narrower and...

A new target for painkillers

Air travel and flu: Post-9/11 restrictions delayed start of season

...lu seasons, when international airline travel went back to its previous level. In contrast, the researchers found no delay in the 2001?002 flu season in France, where there were no flight restrictions. Although other factors may possibly have been involved, the findings suggest that air travel affects bot...

Pattern of human Ebola outbreaks linked to wildlife and climate

"If the spread of the Ebola virus follows its current northeastward path, the next outbreak would be expected to occur in northern Republic of...

Older men treated for early prostate cancer live longer than those who are not

"For this study we looked back over the existing data of a large population of prostate cancer patients, aged 65 to 80, with small tumors that were at a low or intermediate risk of spreading," said senior author Katrina Armstrong, MD, MSCE, who worked on the study with colleagues ...

Leading reason for corneal transplants comes into focus

... those who were had large bumps, or guttae, on the back of the cornea. The Virginia family had severe early disease with men and women equally affected, and the cornea had smaller, finer bumps." Gottsch is looking to one day use various gene therapies to suppress the mutations that he has found. It is ...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

Waiting a day or more to get lab results back from the doctor's office soon could become a thing of a past. Using nanotechnology, a team of University of Georgia researchers has developed a diagnostic test that can detect viruses as diverse as influenza, HIV and RSV in 60 seconds or less. In ad...

Hope for major advance in fighting world killer disease

... oral rehydration therapy, which is cheap and puts back fluids lost by diarrhoea. But disease caused by EPEC and Shigella does not usually respond to oral rehydration therapy. They are much more severe forms of the disease and even if they don't kill they can often inflict irreversible damage that interf...

New engineered drug may offer prolonged arthritis relief

...ng its activity. "With the ELP tag gone, you get back your originally active drug," Shamji said. "That finding was pretty unexpected," Setton added. "We hadn't intentionally designed it to have that feature at all." The researchers now plan to work with collaborators to test the modified drug's abil...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

Populus trichocarpa is one of the tallest broadleaf hardwood trees in the western U.S., native to the Pacific coast from San ...

New HIV statistics indicate increasing toll of AIDS on African American community

Over the 6000 years recorded in the fossil strata the team found 4 devastating events which resulted in...

The flies undergo a major role reversal when the male and female gene versions are switched. With a feminine fruitless gene, male flies adopt more ladyl...

Soil nutrition affects carbon sequestration in forests

"With sufficient soil nutrition, forests increase their ability to tie up, or sequester carbon in woody biomass under increasing atmospheric CO2 concentrations," says Kurt Johnsen, SRS researcher involved ...

UCSD researchers create roadmap to integrin activation

Talin is also critical for activation of related integrins, such as those on white blood cells. In these cells, activation of integrins is a critical step in the sticking and migration of white bl...
