Drilling into the Greenland ice sheet, researchers reconstructed the jet stream's past

New U.S. National Science Foundation-funded research provides insights into how the position and intensity of the North Atlantic jet stream have changed during the past 1,250 years. The findings suggest that the position of the jet stream could migrate outside of the range of natural variability by as early as the year 2060 under unabated greenhouse gas emissions, with potentially drastic weather-related consequences for societies on both sides of the Atlantic.

The Modern Myths

"There is something feeble and a little contemptible about a man who cannot face the perils of life without the help of comfortable myths. Almost inevitably some part of him is aware that they are myths and that he believes them only because they are comforting. But he dare not face this thought! Moreover, since he is aware, however dimly, that his opinions are not rational, he becomes furious when they are disputed."

― Bertrand Russell, Human Society in Ethics and Politics

The litany against fear

"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me.

― Frank Herbert, Dune

Hummingbirds can smell their way out of danger

Vultures aren't the only birds that can sniff

In less time than it takes to read this sentence, hummingbirds can catch a whiff of potential trouble. That is the result of new University of California, Riverside research showing, contrary to popular belief, these tiny birds do have an active sense of smell.

Researchers have known for some time that vultures have a highly sensitive sense of smell, with some species being compared to "airborne bloodhounds." This is due in part to their large olfactory bulbs -- tissue in the brain that controls smell.
