A new University College London (UCL) and University of Nottingham study has found that most neurons in the brain's auditory cortex detect where a sound is coming from relative to the head, but some are tuned to a sound source's actual position in the world.
Study clarifies how we can tell where a sound is coming from
Today, Mars is a freezing cold desert and has been for at least three billion years. And yet, the Red Planet features a network of water-carved valleys that scientists believe formed between 1½ and three million years ago.
Hot rocks, not a warm atmosphere, explain Mars' young, water-carved valleys
Fish don't have to be closely related to be doppelgängers. New research out of Australia shows many distantly related fish species still look and act alike.

New research by Simon Fraser University Professor Karen Kohfeld and University of Tasmania Professor Zanna Chase, published in the journal Earth and Planetary Science Letters, examined how the ocean pulled carbon dioxide out of the atmosphere and into the deep sea during the last Ice Age 125,000 to 18,000 years ago.
