Avian flu hits penguins in Antarctica. Scientists wonder how virus reached the icy region
Antarctica may be too cold and remote but this has not, apparently, helped prevent pigeons living in the icy region to contract avian flu, which is basically transmitted when birds get in contact with infected animals or contaminated secretions and surfaces.
In a study published in the journal of American Society for Microbiology mBio May 6, a group of international scientists described a new strain of avian flu that they discovered in the Antarctic after conducting tests on Adélie penguins.
Investigation into walrus disease closes with no cause identified
An investigation into a mysterious disease afflicting Pacific walruses has been closed with no culprit identified, federal agencies said on Monday.
The investigation into what scientists call an "unusual mortality event" -- an unexpected die-off of a large numbers of animals -- was launched in 2011 when seals and walruses began showing up with bleeding skin lesions, labored breathing, lethargy and hair loss.
Flame Retardant Chemicals Weaken Frogs' Immune Systems
Young frogs exposed to flame retardants have weakened immune systems, which could leave them more susceptible to diseases that are ravaging amphibians worldwide.
A new laboratory experiment is the first to link flame retardants to immune system problems in frogs, and adds to evidence that pollutants may contribute to global declines of their populations.
