Olfactory input dominates reproductive behavior in mice

The unexpected finding may settle an ongoing scientific debate by providing evidence that key reproductive behaviors in mice arise predominantly, if not exclusively, from olfactory input instead of input from the vomeronasal, visual or auditory senses.

...all amount of mercury emitted in North America can settle to the Earth in remote, unspoiled regions. The type called reactive gaseous mercury basic, or elemental, mercury that has combined with another substance is important because rain washes it out of the air very easily.

They also settle in river banks, burrowing into them and riddling them with bore holes up to half a metre long which may eventually cause the bank to collapse.
