This comes from a report commissioned by Rafael Martinez Fortun, from the town of Molina de Segura in Murcia, whose farm was struck by the largest meteorite recovered to date in Spain. In 1863, Queen Isabel II accepted it as a donation to the National Museum of Natural Sciences, where it has been conserved and exhibited ever since…

Kidney cancer is typically without symptoms until it has spread to other organs, when it is also the most difficult to treat. Newer chemotherapies show great promise for extending survival during later disease stages, but they can also be highly toxic…
Deriving plentiful electricity from sunlight at a modest cost is a challenge with immense implications for energy, technology, and climate policy. A paper in a special energy issue of Optics Express, the Optical Society's (OSA) open-access journal, describes a relatively new approach to solar cells: lacing them with nanoscopic metal particles. As the authors describe in the article, this approach has the potential to greatly improve the ability of solar cells to harvest light efficiently…

At Christmas time, we usually expect presents in return for the gifts we give out. And now it seems we humans aren't alone in this calculating attitude. New research published in the Royal Society journal Biology Letters, has shown for the first time that non-humans also keep tabs on the gifts they give, and expect something back in return…
