As A 'Carbon Sponge,' Iron-Poor Coastal Waters Can't Always Do The Job,
...xide--butcertain coastal waters can't perform this trick
because they lack iron, a University of Delaware researcher reports in the June 11 issue of the journal Nature . Just as iron-rich foods help children grow stronger, iron in the ocean gives aboost to microscopic plants called phytoplankton. Without e...
Interdisciplinary Method Offers New Way To Study Ribozymes
... between the twoclasses of sites. "By pulling one trick
each from the toolboxes of chemistry and biology,we have overcome this problem," Lu said. "Our method combinesthe high thiophilicity of mercury with the selective placing of phosphorothioatesto increase the affinity at the active site and permit spe...
Carnegie Mellon Researchers Say Direct Instruction, Rather Than "Discovery Learning" Is Best Way To Teach Process Skills In Science
...ineffective and inefficient." "The trick
is to find ways to get children to understand that what theylearn about a well-designed experiment in one area -- say biology -- has thesame underlying logic as a well designed experiment in some other area, such asphysics or social studies," Klahr e...
New Form Of Gene Therapy Holds Promise For The Future
...alsignals by turning genes on and off. The trick
was to find the right combination of DNA elements todramatically enhance production of luciferase in response to an inflammatoryreaction. The successful combination consisted of three elements ? one from themouse and two from a virus ? that w...
Oaks' Defenses Help Gypsy Moth Caterpillar Fend Off Virus
...relationship between PPO and virus inhibition. The trick
is to put thisknowledge to work in controlling the caterpillars. The constant sound of chewing at the height of a gypsy moth infestationis more than just annoying. Besides damaging the leaf canopy of northeasternforests, these voracious eate...
Genetic Trickery Offers New Way to Target HIV
...y at the University of RochesterCancer Center. "We trick
the virus into shutting down itsreplication process prematurely." While it's too soon to say whether the work will beclinically relevant, the scientists note that the strategy opensup a new research avenue in the gene therapy of AIDS. They havef...
Beset By Human Competition, Penguins Must Take Marathon Food Trips To Avoid Starvation, A Researcher Finds
...bers rose by 3 percent from the previous year. The trick
for penguin survival is getting beyond the first fledgling year, says Boersma. "Once they get to be adults, about 90 percent survive from year to year." Fishing fleets are not the penguins' only harbinger of death. Oil tankers also are plying the wat...
Emory Researchers Advance Gene Therapy Studies For Metastatic Melanoma Treatment
...rs for melanoma that could improve treatment. The trick
is to determine which cytokines actually combat tumor enlargement and which ones create a fertile environment in which the tumor fluorishes. The presence of certain cytokines may indicate that a tumor is indeed fast-growing, calling for a more aggre...
Researchers Corral Millions Of Microscopic Membranes
...mbranes in living cells so closely that they could trick
cells into acting as if they were real. This enabled McConnell and his colleagues to perform key research regarding the nature of the interactions between cells. Groves began working with supported bilayers in 1994. His first discovery was that scori...

Gene-Altered Mouse May Provide New Insights To Parkinson's Disease, Substance Abuse And Schizophrenia
...Parkinson's patients makevery little dopamine, the trick
is to keep what little dopamine they havein the synapse longer, significantly increasing neurotransmission, Caronsaid. This could be achieved with drugs that selectively block the transporterprotein. Such a strategy may prove to be more potent than s...
