"This reflects the ability of St. Jude to provide free treatment to all children regardless of their ethnic or racial backgrounds or their ability to pay; and to tailor the treatment according to their specific need...

Some like it hot: Worms at deep-sea vents favor a fiery 45-55°C

...since they are apparently the only animals able to access -- and feast on -- lush mats of bacteria that thrive around deep-sea vents. The research is described this week in the journal Science. Authors Peter R. Girguis of Harvard University and Raymond W. Lee of Washington State University studied Paralv...

Genetic mutation linked to West Nile virus infection

...CCR5 prevents protective immune cells from gaining access to the brain where they can fight off the infection. It remains to be seen whether the same mechanism is at play in humans. This study might raise a red flag for the use of CCR5 inhibitors in HIV-infected patients -- at least in areas endemic for W...

Most human-chimp differences due to gene regulation ?not genes

This is just the first of a series of similar studies, said Gilad, that will look at changes in gene expression over evolutionary time. The next steps a...

...es. "Through UniQuest, Meristomics had immediate access to substantial commercial expertise and is looking to build on its patent success by attracting further funding to progress the research," Mr Harris said. The anti-cancer molecules are produced by legumes during the early symbiotic relationship wit...

Vital ocean prey play active role in environment

...e edge of the continental shelf, which allows them access to open-water food supplies. Females carrying eggs move offshore to deep water to spawn, where the embryos sink. The embryos hatch into free-swimming larvae at depth, then swim upward over the course of several weeks. The larvae are at this stage dep...

Gene thwarts some pathogens, gives access to others, could save crops

... fruits and vegetables. But the same gene provides access to a different type of pathogen. A Purdue University plant molecular biologist and his collaborators in Austria and North Carolina identified the gene that helps plants recognize pathogens and also triggers a defense against disease. The gene and it...

Contaminants linked to sturgeon decline in Columbia river

Schreck and Feist studied white sturgeon from three reservoirs along the Columbia River and from areas downstream of Bonneville, the last dam on the river in its path to the Pacific Ocean. The researchers found some of the fish...

Study may help slay 'Yellow Monster'

A goal of the partnership is to address these disparities by training Native students for cancer-related careers. In this way, Stearns and her students can help slay the yell...

New weapon in battle against osteoporosis
