Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...rotein--NS5--from the tick-borne Langat flavivirus counteracts the natural ability of interferon to combat the virus. Langat virus was originally isolated in the 1950s in Malaysia and Thailand. Langat virus can infect people following a tick bite, but there are no cases of natural disease recorded. In the 1970s ...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

... nanoscale assembly of molecules that successfully counteracts and inhibits anthrax toxin in animal and laboratory experiments. The novel approach used to neutralize anthrax toxin could be applied in designing potent therapeutics for a variety of pathogens and toxins, according to the researchers. Anthrax toxin...

Why do cold animals make bigger babies?

...? One theory suggests the larger size of offspring counteracts their slow growth in the cold. Yet another theory suggests large offspring are not directly linked to temperature at all. Instead, large offspring just happen to be produced by large mothers, who grow large because they require more energy to reprodu...

Global 'sunscreen' has likely thinned, report NASA scientists

...been observed. "Less sunlight reaching the surface counteracts the effect of warmer air temperatures, so evaporation does not change very much," said Gavin Schmidt of GISS, a co-author of the paper. "Increased aerosols probably slowed the expected change in the hydrological cycle." Whether the recent decline ...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...tudy that revving up a crucial set of muscle genes counteracts the damage caused by a form of muscular dystrophy. Reporting in the April 1 issue of Genes and Development, the researchers demonstrated that manipulating a genetic molecular switch increased the genes?activity in the muscles of mice with Duchenne m...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...ount known properties of the MRI machine sound and counteracts them. When tested with human listeners, the system reduced noise levels and improved audibility conditions for sounds, without interfering with the MRI's scanner's image quality (4pPP16).
