Highly adaptable genome in gut bacterium key to intestinal health

... shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates. This adaptive mechanism not only allows the bacterial species to survive rapidly changing nutrient conditions but also helps maintain the functions and stability of the gut's highly c...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...ing from Massachusetts joined forces and developed gear to help marine mammals detect and avoid gillnets before coming into contact with them, as well as allow them to escape unharmed if they still become entangled. To create avoidable, detectable, safer gear, the team tinkered with the chemical propertie...

Future diabetes drugs may target new protein interaction

..., the liver's production of sugar kicked into high gear because amounts and activities of the two proteins, called sirtuin1 and PGC1-alpha, increased when dietary calories weren't available. Once mice were fed, levels of the two proteins went down and sugar production ceased. "It isn't a coincidence," sa...

PHACCS, an online tool for estimating the structure and diversity of uncultured viral communities using metagenomic information

Once mice were fed, levels of the two proteins went down and sugar production ceased. "It isn't a coincidence," sa...

Computational verification of protein-protein interactions by orthologous co-expression

Internet viruses help ecologists control invasive species

...because humans transport the eggs on their fishing gear and pleasure boats. Professor Norman Yan of Ontario's York University has demonstrated that predation by the spiny water flea causes an average loss of three zooplankton species. Thus, as the species spreads, it could cause loss of thousands of popu...

Scientists discover global pattern of big fish diversity in open oceans

... Pelagic longlines are the most widespread fishing gear in the open ocean ?baited lines up to 100 km in length that catch a wide range of predators. While they target tuna or billfish, they catch many other species too, including sharks, sea turtles and seabirds. To see whether findings based on the Japan...

UMaine teams with fishermen to study affects of trawling on seafloor ecology

...d complex habitat and it is clear that rock hopper gear reduces habitat complexity," said Watling. "No good habitat, hardly any fish." The good news is that recently protected habitats are recovering. While anything resembling a "natural" condition would certainly be far in the future, Knight found that ...

Life and death in the hippocampus: what young neurons need to survive

...logical Studies pin-pointed the molecular survival gear required for a young neuron to successfully jump into the fray and hook up with other cells. In a study published in a forthcoming issue of Nature, researchers in the lab of Fred H. Gage, Ph.D., a professor in the Gene Expression Laboratory and th...

UN review shows need to halt destructive fishing practice
