Most studies of the impact of humans on other species tend to be negative as more and more habitats are destroyed or degraded, so a new study provides a surprising contrast. It adds weight to the view that one of the northern hemisphere's best-loved summer visitors has vastly increased in range and numbers as a result of human activity. The barn swallow is found across North America, Europe and...

the verge of showing the potential clinical value of embryonic stem cell research. Our research clearly shows that stem-cell-derived retinal cells can rescue visual function in animals that otherwise would have gone blind. We are hopeful that the cells will be similarly efficacious in patients. " The company hopes to start its clinical trial this spring. At a later point, the company also hopes...

Large animals have a disproportionate capacity to transport nutrients along gradients and against water flow directions, making them more available to ecosystems and ultimately saving them from disappearing in sea floor sediments. Megafauna extinctions have reduced this capacity dramatically, while humans and their livestock aren’t stepping in to restore this important ecosystem service.

1 LIP6, Université Pierre et Marie Curie, 4 Place Jussieu, 75252 Paris Cedex 05, France. [email protected] Abstract. Knowledge about forced moves enables to select a small number of moves from the set of possible moves. It is very important in complex domains where search trees have a large branching factor. Knowing forced moves drastically cuts the search trees. We propose a language an...

UK higher education institutes are lobbying to get the commission to accept the idea of credits based on learning outcomes rather than length of study.
