[4] Some 14 million people are stung annually in the United States, [5] suffering reactions that vary ...

Scientists found that 10 or more fire ants can stick together to build a life-saving raft in floods. Fewer than 10 ants can’t form a stable raft because the “Cheerios effect” of fluid ...
Arsenic has been known since ancient times to be poisonous to humans. [13] However, a few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic have been proposed to be an essential dietary element in rats, hamsters, goats, and chickens. Research has not been conducted to determine whether ...
