The research, published by Cell Press in the April 10th issue of the journal Molecular Cell , describes the ...

Racing cane toads reveals they get cold feet on Southern Australia invasion

Cane toads weren't allowed to compete in the Olympics, but scientists have raced cane toads in the laboratory and calculated that they would not be able to invade Melbourne, Adelaide or Hobart and are unlikely to do well in Perth or Sydney, even with climate change. According to research by Dr ...

New map outlines risk of zebra mussel invasion

Researchers identify new way the malaria parasite and red blood cells interact

... For decades, researchers have known that a molecule called glycophorin B, which is found on the surface of human red blood cells, is important for invasion of the malaria parasite. However, the specific molecule by which the malaria parasite attaches itself to invade the host was not known until now. T...
