POPSThe key to oil independence is a new electrical grid It seems that with alternative sources of energy, such as wind and solar, the United States has the potential means to substantially reduce our dependence on oil - especially once plug-in cars are on the market. But until we substantially upgrade our nation's electrical grid with modern technology that will enable the energy created by these sources to be transmitted intelligently around the county, their impact will be limited. It's going to take a greater commitment from Congress to jump start this. Making it happen will provide a huge boost to our economy, environment and political leverage with the Middle East, Russia, Venezuela and more.

POPSRocket Scientists Say We'll Never Reach the Stars Even the most theoretically efficient type of propulsion, an imaginary engine powered by antimatter, would still require decades to reach Alpha Centauri, according to Robert Frisbee, group leader in the Advanced Propulsion Technology Group within NASA's Jet Propulsion Laboratory. And then there's the issue of fuel. It would take at least the current energy output of the entire world to send a probe to the nearest star

POPSNano-Solar Power -Will it Be the Next Revolutionary Technology? Not that the technology is perfect. The system can absorb energy very well, but that's no good to anyone until they work out a way to harvest it from the sheet - when you're dealing with a hyper-complex web of millions of units oscillating at trillions of cycles per second, you can't just solder copper wires to the ends and call them plus and minus. This isn't a mistake or a weakness in the concept though; it's an issue because no-one has ever done this before. You know, the kind of thing that happens with cutting edge invention.

POPSAre We Being Paged? Could this be the first signal detected from deep space? Or could it just be a college prank or programming error? MT C

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?
