POPSDoes the Milky Way Influence Earth's Biodiversity Cycles? Research Says "Yes" The boost in cosmic-ray exposure may have a direct effect on Earth's organisms, according to paleontologist Bruce Lieberman. The radiation would lead to higher rates of genetic mutations in organisms or interfere with their ability to repair DNA damage. In this way, the process could lead to new species while killing off others. If future studies confirm the galaxy-biodiversity link, it would force scientists to broaden their ideas about what can influence life on Earth. "Maybe it's not just the climate and the tectonic events on Earth," Lieberman said. "Maybe we have to start thinking more about the extraterrestrial environment as well."

POPSAmateur spies gassy 'cosmic ghost' Some people get to name an object. Even fewer get to name a new class of object. Now we'll have people scanning the skies for Voorwerps. One day we might even discover what they are. I wonder if they come in different colours?

POPSThe Milky Way Over Ontario Sometimes, after your eyes adapt to the dark, a spectacular sky appears. Such was the case earlier this month over Ontario, Canada, when part of a spectacular sky also became visible in a reflection off a lake. To start, the brightest objects visible are bright stars and the planet Jupiter, seen as the brightest spot on the upper left. A distant town appears as a diffuse glow over the horizon. More faint still, the disk of the Milky Way Galaxy becomes apparent as a dramatic diffuse band across the sky that seems to crash into the horizon far in the distance. In the foreground, a picturesque landscape includes trees, a lake, and a stone wall. Finally, on this serene night in July when the lake water was unusually clam, reflections appear. Visible in the lake are not only reflections of several bright stars, but part of the Milky Way band itself. Credit & Copyright: Kerry-Ann Lecky Hepburn (Weather and Sky Photography)

POPSYou Must Remember This Easy read, quite amusing, a somewhat sardonic slant on current obsessions for neuroporn and the current cutting edge of the self-improvement industries. Mind you, I may have made up that reading rather than remembered it.

POPSIs a 'Dark Force' Pushing the Universe Apart? Astronomers now recognize that the eventual fate of the universe is inextricably tied to the presence of dark energy and dark matter.The current standard model for cosmology describes a universe that is 70 percent dark energy, 25 percent dark matter, and only 5 percent normal matter.
