Climate impacts of melting ice sheets refined
Nature Published February 6, 2019 13:00 ET (News release from Nature Research Press) Researchers used satellite measurements of recent ice-mass changes to refine simulations of the melting Antarctic and Greenland ice sheets and the potential impacts on climate. They find that, within a few decades, increasing meltwater will slow the major ocean currents, climate variability may […]
Human hunger for meat pushing biggest animals to extinction
Conservation Letters Published February 6, 2019 10:00 ET (News release from Oregan State University) At least 200 species of large animals are decreasing in number and more than 150 are facing threat of extinction. Minimizing the direct killing of large vertebrate animals is an important conservation tactic that might save many of these iconic species as […]

Dopamine directly affects how much we enjoy music
PNAS Published January 21 Dopamine directly increases our enjoyment of listening, singing, or playing to music, which confer no known survival advantage. This double blind within-subject study directly manipulated healthy participants’ dopamine levels while they listened to music. The results indicate how an individual’s ability to absorb dopamine may play different, unforeseen roles in the […]
