How healthy is that marsh? Biologists count parasites

...h at the U.S.-Mexico border. "The horn snail is a mobile data recorder," Lafferty said. "It is a hub for more than 20 trematode species." If any one requisite intermediate host is missing, the parasite cannot reproduce and hence will be underrepresented in the resident snail population, he explained. A su...

Innocuous intestinal bacteria may be reservoir for resistance

...ibiotic use on the farm. "This work suggests that mobile DNA elements like plasmids are responsible for the rapid spread of drug resistance on farms. Ecology appears to play a more important role in the emergence of drug resistance in Salmonella than therapeutic antibiotic use," says Sanchez. ...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

... travel across the United States. "In the highly mobile U.S. population, travel restrictions alone will not be enough to stop the spread; a mixture of many mitigation strategies is more likely to be effective than a few strictly enforced ones," said Kadau, also of Los Alamos' Theoretical Division. The mo...

Major WHO study concludes calcium supplements can reduce complications during pregnancy

... takes more energy for the drugs to close the more mobile flaps of the mutant. Perryman and his colleagues also observed that the flaps opened in a seesaw motion on each side, pinching the "cheek and "ear" together. That observation suggested to them that a small molecule might be able to wedge between the...

Penguins waddle but they don't fall down, UH researchers say

... findings could even allow the development of more mobile robots. His study on walking stability features dozens of King penguins from Moody Gardens in Galveston. Though these endearing animals may seem unsuited for rough terrain, penguins will travel more than 75 miles across rugged ground terrain to re...

So the York team has redeployed the enzyme in the bacteria into plants, giving them the ability to biodegrade the pollutant more eff...

Exercise aside, genes may ultimately dictate seniors' mobility

...about 41 percent of study participants became less mobile over the four-year period. Even though people who exercised were less likely to develop substantial physical limitations, not everyone received the same benefits, even if they exercised with the same intensity. About a third of the seniors engaged i...

Researcher gets NSF grant to create mutant maize lines

...other. Called transposons, or jumping genes, these mobile pieces of DNA knock out the function of genes they jump into, thereby mutating the genetic makeup. What is unique about this collection is that a single gene will be disrupted in each line while the 50,000 or so other genes are kept exactly the same ...
