Ocean climate predicts elk population in Canadian Rockies

...ans colder and snowier conditions than usual. More snow is bad news for elk, which have heavy bodies and long, narrow legs and small hooves. The deeper the snow, the further they sink. Conversely, wolves have relatively light, sleek bodies and big, wide paws that act like snowshoes. In the Canadian Rockie...

NJIT study shows nanoparticles could damage plant life

...tts. The particles can also mix with rainwater and snow and gradually work their way into soil. It is difficult to take results from a lab experiment and conclude that is what happens in the real world, said Watts. "But we speculate that air deposits of nanoparticles or water transport of them are ways in...
