Scientists from the Camborne School of Mines have conducted a ground-breaking analysis of a Martian meteorite that dates back to the formation of the Earth.
Dr Gavyn Rollinsonused pioneering technology to map the mineralogy of a section of the meteorite – which was discovered in North Africa and is around 4.4 billion years old. (more…)
A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations.
Understanding the way in which social behaviours such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates.
Dr Florence Débarre of Biosciences at the University of Exeter led a study, published in Nature Communications, which presents a comprehensive framework that applies to a large class of population structures and identifies the crucial elements which support the evolution of social behaviour.

The last large populations of the leatherback turtle are at risk because their migratory routes in the Atlantic Ocean clash with the locations of industrial fisheries, a new study shows.
Researchers used data from satellite transmitters attached to the turtles to track their movements across the Atlantic Ocean. These movements were then overlapped with information on high pressure fishing areas to identify where the turtles are most susceptible to becoming entangled and where they may drown. (more…)
