Many billions of rocky planets in habitable zones around red dwarfs in Milky Way Posted: 28 Mar 2012 06:09 AM PDT Rocky planets not much bigger than Earth are very common in the habitable zones around faint red stars, according to new research. The astronomers estimate that there are tens of billions of such planets in the Milky Way galaxy alone, and probably about one hundred in the Sun's immediate neighborhood. This is the first direct measurement of the frequency of super-Earths around red dwarfs, which account for 80 percent of the stars in the Milky Way.

Stopping statin therapy increases risk of death for rheumatoid arthritis patients Posted: 28 Mar 2012 06:08 AM PDT Patients with rheumatoid arthritis (RA) who discontinue use of statin therapy are at increased risk of death from cardiovascular disease and other causes.

Powerhouse in the Crab Nebula: MAGIC telescopes observe pulsar at highest energies yet and strongly challenge current theories Posted: 28 Mar 2012 06:08 AM PDT The pulsar at the center of the famous Crab Nebula is a veritable bundle of energy. Astronomers observed the pulsar in the area of very high energy gamma radiation from 25 up to 400 gigaelectronvolts (GeV), a region that was previously difficult to access with high energy instruments, and discovered that it actually emits pulses with the maximum energy of up to 400 GeV -- 50 to 100 times higher than theorists thought possible. These latest observations are difficult for astrophysicists to explain.

Building lightweight trains Posted: 28 Mar 2012 06:08 AM PDT The less trains weigh, the more economical they are to run. A new material capable of withstanding even extreme stresses has now been developed. It is suitable for a variety of applications, not least diesel engine housings on trains -- and it makes these components over 35 percent lighter than their steel and aluminum counterparts.

Playing at home energy savings Posted: 28 Mar 2012 06:08 AM PDT An approach to cutting domestic energy consumption based on playing a game - Energy Battle - can lead to household savings of up to 45% on electricity consumption and lead to better energy-saving habits, says a new study.

Wave character of individual molecules revealed Posted: 28 Mar 2012 06:08 AM PDT Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of the everyday world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, scientists have recorded the interference process of individual molecules. "Seeing how the interference pattern develops with every light spot, molecule after molecule, and how a basic principle of quantum mechanics is visualized enhances our understanding of the atomic world," explains one of the researchers.

How to save Europe's most threatened butterflies Posted: 28 Mar 2012 06:08 AM PDT New guidelines on how to save some of Europe's most threatened butterfly species have now been published. The report covers 29 threatened species. The new report will provide crucial information on how to achieve this goal and meet their international biodiversity targets.

Exploding dinosaur hypothesis implodes Posted: 28 Mar 2012 06:08 AM PDT A pregnant ichthyosaur female that perished 182 million years ago puzzled researchers for quite some time: The skeleton of the extinct marine reptile is almost immaculately preserved and the fossilized bones of the mother animal lie largely in their anatomical position. The bones of the ichthyosaur embryos, however, are a different story: For the most part, they lie scattered outside the body of the mother. Such peculiar bone arrangements are repeatedly found in ichthyosaur skeletons. According to the broadly accepted scientific doctrine, this is the result of exploding carcasses: Putrefaction gases produced during the decomposition process cause the carcass to swell and burst. However, sedimentologists, paleontologists and forensic scientists have now managed to dispel the myth of exploding dinosaur carcasses.
