New tumor-suppressor gene discovered

..." As part of the research, Lai's lab added a human mats gene to tumor-plagued flies known to have a genetic defect in their mats gene, then found that tumors no longer developed within this line of flies in individuals that had i...

Discovering an ecosystem beneath a collapsed Antarctic ice shelf

...ebris that have already begun to bury the delicate mats and mollusks established within the underwater environment. He added that there may be a sense of urgency to investigate the unusual seafloor ecology below the Larsen shelf because of the likelihood of increased sediment deposition. In addition, he ...

Freeze-dried mats of microbes awaken in Antarctic streambed

... funded by the National Science Foundation. "These mats not only persisted for years when there was no wat...channel, photosynthesis began the same day and the mats became abundant within a week," she said. "This showed us that they had been preserved in a cryptobi...

Drugs from the deep blue

...teria, single-celled organisms that occur as slimy mats or filaments in places such as coral reefs and mangrove lagoons. Some of these compounds have biochemical activities that could be useful in medicine -- killing microbes, stopping growth of cancer cells, or affecting the flow of calcium in and out o...

Ancient trans-Atlantic swarm brought locusts to the New World

...and landed in the ocean, they formed huge floating mats of dead locusts," says Lovejoy. "The other locusts would land on these mats, rest and feed on the dead bodies, then take off and keep flying." Another possibility is that among the millions of swarming locusts were a few exceptional insects that some...

Hot-spring bacteria flip a metabolic switch

... as Synechococcus are often found in the microbial mats that carpet hot springs, where life exists at near-boiling temperatures. These mats are highly organized communities where different organisms split up the work, with cyanobacteria ser...

Virginia Tech scientists develop process for creating biocompatible fibers

... single-step process for creating nonwoven fibrous mats from a small organic molecule ?creating a new nano... weight molecules and electrospun. The size of the mats is limited only by the amount of material, such as lecithin. "This represents the synergy of elect...

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

...nly 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 Paralvinella sulfincola, a member o...

Invasive species alter habitat to their benefit

...id cattails had higher nutrient levels and heavier mats of dead cattail stems than areas with only native ...rid cattails; in the second she added litter---the mats of dead stems that accumulate around hybrids. A third plot received both live hybrids and litter, an...

Nanotubes used for first time to send signals to nerve cells

...neuroblastoma cells. They compared cells placed on mats made of "functionalized" SWNTs, carbon nanotubes with additional molecules attached to their surfaces that may be used to guide cell growth or customize nanotube electrical properties, to cells cultured on unmodified "native" carbon nanotubes and con...

Caribbean frogs started with a single, ancient voyage on a raft from South America

...aribbean islands likely hitched a ride on floating mats of vegetation called flotsam, which is the method typically used by land animals to travel across salt water. "Some rafts of flotsam, if they are washed out of rivers during storms and caught in ocean currents, can be more than a mile across and cou...
