...ations." "This is a very important piece of work," notes Judah Folkman, M.D., of Children's Hospital Boston and Harvard Medical School, in whose laboratory endostatin was first discovered with Michael O'Reilly in 1997. "This paper shows an emerging set of proteins in the body which guard against abnormal a...

UW researchers find second anthrax toxin receptor

... is much more complicated than previously thought, notes Young, an expert on receptor molecules. Scientists do know that to prevent anthrax disease, antibiotics must be administered immediately to kill anthrax bacteria that typically enter the body as spores via the skin, lungs or gastrointestinal tract. O...

The structure behind the switch

...n classes are created is a nearly perfect system," notes Michael Lieber, M.D., Ph.D., professor of pathology and biochemistry and the study's principal investigator. "And yet, the DNA mechanism for how a cell switches from producing one class to producing another has remained a mystery for almost 20 years....

The new role of S&T leaders

...to move forward or to stay the course." Jackson notes that the AAAS has a unique opportunity to play a significant role in education and in science and technology public policy. The challenge, she says, will be to unite with research universities and corporate laboratories. "Scientists and engineers a...

Fruit consumption related to increased risk of Parkinson's?

...ides or herbicides, rather than the fruit itself," notes study author Andrew Grandinetti, PhD, of the Pacific Biomedical Research Center, University of Hawaii and Manoa. "High fruit intake is still an important protective factor against many chronic diseases. However, these findings suggest that further re...

...you listen to a noise that contains all pitches of notes except for one, then switch it off, you hear the missing tone linger, even though it was never played. This auditory illusion cannot be explained by the apparatus of the ear itself, and must arise in the brain. This paper shows how some simple models...

Other brush structures can be grown from nano-particles of glass or gold, giving rise to corona-shaped structures that combine organic and inorganic materials at the nano-scale through extremely strong chemical covalent bonds (see Fig...

Scientists find new way to grow human embryonic stem cells

...hat keeps them from doing so at the drop of a hat, notes Cheng. "Mouse embryonic stem cells have been studied for more than 20 years," he says. "We know what signals keep them from differentiating, we know the whole pathway. But human embryonic stem cells have only been studied for the last five year...

Rockefeller, Weill Cornell researchers find link between estrogen, brain structure changes

...he subcellular level through electron microscopy," notes Milner, professor of neuroscience in the Division of Neurobiology at Weill Cornell. "We were able to visualize precise changes in protein distribution at the actual dendritic spines of the neurons." Findings from several previous studies have been m...

New, more effective option for gene data mining identified

...usters obtain by the different methods. Acharya notes "Even simple visual inspection showed that the KL method created clusters that were better separated compared to the most popular method. The evaluation with quantitative measures confirmed the visual observations." The KL method uses the KL diver...

BIDMC researchers identify source of preeclampsia

...work to develop strategies to treat preeclampsia," notes Karumanchi. "We're obviously a number of years away from being able to put these to use in humans but these results are an important step in the process." Furthermore, adds study coauthor Vikas Sukhatme, M.D., Ph.D., this study has important implicat...

Tapeworm's chemical trick could make drugs more effective

.... "Inside cells, cyclic GMP is a signal molecule," notes Oaks, a professor of comparative bioscience. "It tells cells how to behave. When the tapeworm secretes this signal molecule, the intestine closes off and nothing moves. That suggested to us that the intestine is not digesting material as it normally ...

Rainforests at risk: Where theres smoke, theres even more fire

... emissions skyrocket. Data is scarce, but Cochrane notes that three rainforest fires in Mexico, Brazil and Indonesia may have equaled 41 percent of world fossil fuel emissions in 1998. The problem, Cochrane said, is that fire is so common in rainforests. People routinely use fire to clear existing forests,...
