Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

...ons, including deletions, mutations, many types of lesions that would inactivate the protein," Kingsley said. But in contrast, "in the fish we don't see any mutations that would clearly destroy the protein." There are some very minor changes in many populations, but these changes do not affect key parts of ...

Researchers reveal the infectious impact of salmon farms on wild salmon

... and in some cases be lethal - as they create open lesions on the surface of the fish that compromises a fish's ability to maintain its salt-water balance. When infection rates are high enough, the parasites feed on the fish at rates greater than the fish can feed itself, literally eating the fish alive. Adu...

Association of herpesvirus with lung disorder questioned

... hypertension is characterized in part by vascular lesions in the lung, and may lead to heart failure. Some cases are associated with genetic susceptibility, the investigators noted, but the pathogenesis of most cases is not known.
