How fish conquered the ocean

..., and adds, "This is especially so for their newly spawned eggs since they lack the adult organs and mechanisms responsible for coping with these problems. For years we studied various aspects of the physiological adaptations of the fish egg to the marine environment. It is most satisfying that Dr. Finn has ...

Biofuel cells without the bio cells

...proteins rendered portable from the organisms that spawned them could make miniature bioreactor cells feasible. "We show that you can directly transfer electrons to a mineral using a purified protein, and I don't think anyone had shown that before," said Thomas Squier, senior author and lab fellow at the D...

Molecular force field helps cancer cells defend against attack

...or FAK, is commanding increasing attention and has spawned a flurry of research designed to develop new drug therapies, said Cance, who is known internationally for his genetic investigations of tumor survival. These medicines would prevent FAK from linking with the protein known as vascular endothelial grow...

Thin tough skin, slow-growing gills protect larval Antarctic fish

...m 2000 to 2004, were analyzed. While each species spawned at different depths, all larvae swam upward into platelet ice, located just below several meters of surface ice, when they hatched, seeking perhaps a safe area to hide from predators, Cziko said. The average freezing point of the larval fish fluids ...

MIT researcher presents new view of how the cortex forms

..., that the task-specific regions of the cortex are spawned by a zone of "originator" cells; or that long nerve fibers from the thalamus, a large ovoid mass that relays information to the cortex from other brain regions, are activated by external stimuli to impose identity on the homogeneous blob. New eviden...

Same-sex mating by fungi spawned infection outbreak, evidence suggests

... between two less harmful yeast strains might have spawned an outbreak of disease among otherwise healthy people and animals on Vancouver Island, British Columbia, Howard Hughes Medical Institute geneticists at Duke University Medical Center have reported. The fungus, Cryptococcus gattii, is normally restric...

New factor implicated in allergy and asthma attacks

...ules known as "reactive oxygen species," which are spawned by interactions between a single pollen-carried enzyme and the cells that line airways. And, the researchers say, if an effective way can be found to reduce that damage--called "oxidative stress"--new and powerful allergy and asthma therapies may res...

Making plant cells work like miniature factories

...equent study of proteins produced by certain genes spawned the field of proteomics. Now, a group of researchers at the U.S. Department of Energy's Ames Laboratory at Iowa State University will use $1.02 million in DOE start-up funding to begin understanding the chemical processes that take place within the ...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

... these samples are still being examined, they have spawned some early, intriguing results. For example, the cores contained many small sea creatures; other sampling techniques turned up relatively large specimens, including sea cucumbers up to 20 centimeters long. In addition to collecting a large number of...

Weizmann Institute scientists develop a new approach for directing treatment to metastasized prostate cancer in the bones.

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer
