| Ancient African cattle first domesticated in Middle East, study reveals Posted: 28 Mar 2014 09:10 AM PDT The genetic history of 134 cattle breeds from around the world has been completed by a group of researchers. In the process of completing this history, they found that ancient domesticated African cattle originated in the 'Fertile Crescent,' a region that covered modern day Iraq, Jordan, Syria and Israel.  |
| More male fish 'feminized' by pollution on Basque coast Posted: 28 Mar 2014 07:30 AM PDT Evidence of 'feminization' of male fish in the estuaries of Gernika, Arriluze, Santurtzi, Plentzia, Ondarroa, Deba and Pasaia has been discovered. The first cases -- 2007-2008 -- were detected in Urdaibai, and the most recent data confirm that they are also taking place in other estuaries. Pollutants acting as estrogens are responsible for this phenomenon which, among other changes, is causing ovocytes to appear in male fish.  |
| Revolutionary solar cells double as lasers Posted: 28 Mar 2014 05:55 AM PDT Latest research finds that the trailblazing 'perovskite' material used in solar cells can double up as a laser, strongly suggesting the astonishing efficiency levels already achieved in these cells is only part of the journey.  |
| EEG study shows how brain infers structure, rules when learning Posted: 25 Mar 2014 04:08 PM PDT A new study documents the brain activity underlying our strong tendency to infer a structure of context and rules when learning new tasks (even when a structure isn't valid). The findings, which revealed individual differences, shows how we try to apply task knowledge to similar situations and could inform future research on learning disabilities.  |
