When male Augrabies flat lizards (Platysaurus broadleyi) size each other up for a brawl, they look at the ultraviolet (UV) color of their opponent´s throat, according to a study published online 3 January in Biology Letters. Researchers found that when they blocked this UV patch with sunscreen, lizards were much more likely to be challenged by their foes. The results suggest that such coloration can help males maintain dominance--as long as they avoid the SPF 50.     Sunday, May 06, 2007 COSMIC TORNADO   Cosmic tornado. The tantrums of an infant star have carved a striking helical shock wave in space. NASA´s Spitzer Space Telescope found the glowing infrared feature in a fertile nursery of more than 100 stars about 550 light-years away. Blasting downward from an unseen active star above the image, this jet may trace out the poorly understood magnetic fields that probably wind through the churning cloud of gas and dust. Astronomers released the false-color image 12 January at a meeting of the American Astronomical Society.     Sunday, May 06, 2007 DOUBLE VISION   When it comes to tracking geomagnetic storms, two eyes are better than one. The pair of Solar Terrestrial Relations Observatory (STEREO) spacecraft--launched on 25 October 2006--have imaged two massive streams of hot plasma streaking away from the sun (blue) at more than 1000 kilometers per second. The spacecraft will soon be respectively leading and trailing Earth, as it orbits the sun, at sufficient distances to provide 3-D tracking--and enhanced forecasting--of such solar ejections, which threaten satellites, radio communications, and GPS operations.     Sunday, May 06, 2007 WINGED WONDER   The first fossil of a gliding lizard has been found in northeastern China, and judging by its wing design, it was an ace. Rather than using modified forelimbs for powered flight (as contemporary pterodactyls did), 15-centimeter-long Xianglong zhaoi sailed with a pair of webby wings built on supersized ribs, leaving its limbs free for grabbing and climbing trees, researchers report online the week of 19 March in Proceedings of the National Academy of Sciences. Despite its fine features, the 100-million-year-old glider seems to have been an early experiment: birds, which would soon dominate the skies, grew wings from their forelimbs, and the only gliding reptile around today, the draco lizard, has wings that are less aerodynamic.     Sunday, May 06, 2007 THE PATH OF THE LOVE - PHOTOBOOK UIVERSE (21 Pictures) NICE PLACE (7 Pictures) <-Back  1  Continue-> The highest rated images: No pictures have been rated yet!
