Researchers reveal the infectious impact of salmon farms on wild salmon

...rom farms to wild salmon. However, a bitter debate continues in British Columbia and the Pacific Northwest as to whether salmon farms are contributing to sea lice infections of wild salmon at all. "Parasites are a key negative side effect of fish farms on the local fish stocks," says Andrew Dobson, an epidemi...

The group continues to wade out into nature, collecting additional stickleback species from around the world that can reveal whether particular genes are always reused when the animals adapt to new conditions, or if evolution has other tricks up its sleeve to push organ...

Studies reveal methods viruses use to sidestep immune system

...urn on the genes to make interferon, and the virus continues to replicate unimpeded. "Having identified RIG-I, now we can spend our time completely defining the signaling pathway that goes from RIG-I all the way down to IRF-3," Dr. Gale said. "Once we've done that, we hope to identify parts of the pathway to ...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...e grasshopper is inactive and resting, however, it continues to breathe in oxygen at the same high volume it uses while flying. The result is excess internal oxygen that can cause oxidative damage -- the destruction of biomaterial due to excess oxygen -- to tissues. To protect their bodies, insects like grassh...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

Although there has been a conspicuous absence of right whale sightings from the outer shelf and slope habitat in recent years, this may be due, at least in part, to a lack of survey effort there. Results of a...
