(PhysOrg.com) -- Jasper Kirkby, a physicist at CERN and colleagues have built an experimental climate chamber to measure the impact of cosmic rays on aerosol creation to mimic the creation of clouds in Earth's atmosphere. So far, as the team describes in their paper published in Nature, there appears to be some evidence of aerosol creation, but not enough to account for cloud formation, and thus there’s no evidence yet to show that cosmic rays have an impact on global temperatures.

An unmanned Russian cargo ship carrying tons of supplies for astronauts on the International Space Station suffered a major malfunction after launching today (Aug. 24) and ultimately crashed back to Earth, NASA officials say

By David Fogarty SINGAPORE (Reuters) - Scientists have yet to discover, or classify, about 90 percent of the plant and animal species on Earth, which is estimated to be home to just under 9 million species, a study says. [More]

They say there's no place like home. Well, we may get to test the idea. Because astronomers have located a world that could be a bit like Earth some 36 light-years away.

Early Earth's atmosphere provided little shielding for ultraviolet light from space, so many prebiotic molecules, bombarded by it and light of other wavelengths, had a hard time surviving at all.

(PhysOrg.com) -- Neutrons, those particles that reside here on Earth inside the nucleus of atoms, along with protons, collectively called nucleons, are thought to exist in the far reaches of the universe inside of so-named neutron stars, which are the remnants of stars that have exploded. In a paper published on the preprint server arXiv, Spanish physicists Felipe Llanes-Estrada, and Gaspar Moreno Navarro, suggest that the densities in the cores of certain sizes of such neutron stars might be so great as to squash the neutrons down from their normal spherical shape, into cubes.

Join a global effort to document all 1.9 million named species of animals, plants and other forms of life on Earth [More]

In a geologic instant, the K-T extinction event about 65 million years ago left Earth's skies empty of pterosaurs , extirpated the mosasaurs and their ammonite prey from the seas, and, of course, denuded the land of non-avian dinosaurs. But what if, by some fluke of evolutionary history, this catastrophe never happened and the global summer of the dinosaurs was allowed to continue

Dear EarthTalk : As I understand it, “debt-for-nature swaps” are arrangements by which countries can erase debt by preserving land.

Italian researchers using data from the satellite PAMELA have proven that theories showing there ought to be a ring of antiprotons encircling the Earth due to cosmic rays colliding with nuclei in the upper atmosphere are correct. Piergiorgio Picozza from the University of Rome, Tor Vergata, and a host of colleagues have published the results of their findings in arXiv.

The Ajiro--a concept from Australia--would come from the Earth fully formed. Is this the first step for a sustainable manufacturing economy?
