Retina adapts to seek the unexpected, ignore the commonplace

...n visual environments such as forests or fields of grass with many vertical elements but only rare horizontal features, the retina adjusts to suppress the routine vertical features while highlighting the singular horizontal elements.

Ocean climate predicts elk population in Canadian Rockies

... already at a deficit in the winter. There is less grass to eat, and their bodies have to work harder and use more energy to stay warm," said Hebblewhite, who studies in the U of A Department of Biological Sciences. Cold, wet weather alone is enough to decrease an elk population, but when wolves are added...

Life detection instrument passes key test on road to Mars

...anet Mars. In a place that hadn't seen a blade of grass or a bug for ages, and contending with dust and temperature extremes that left her either freezing or sweating, Skelley ran 340 tests that proved the instrument could unambiguously detect amino acids, the building blocks of proteins. More importantly...
