Size doesn't always matter when it comes to NASA's pretty pictures, but it may certainly make an impression upon visitors at the Adler Planetarium in Chicago. The planetarium has revealed a gigantic Milky Way panorama that stretches 120 feet long and 3 feet wide at the sides. The center of the picture bulges out to 6 feet wide to accommodate the center of the galaxy.

Man, those scientists just love their glowing lab subjects. First came mice, and then recently the first primates got some jellyfish genes implanted into their DNA. Now, scientists at Emory University have implanted the gene for jellyfish fluorescent protein in prairie voles.
An array of microelectrodes connects with the brain, potentially allowing paralyzed patients to control computer interfaces with their minds.

Each issue of Popular Science opens with Megapixels--two of the most amazing images from the world of science and technology that month. Here, we've compiled them all from 2009 for your viewing pleasure, with some additional images from years past and present added to the mix.
President Obama lifted the Bush-era restrictions on embryonic stem cell lines last spring, but hundreds of cell lines have remained locked away undergoing review. Now the National Institutes of Health (NIH) has finally deemed 13 embryonic lines ready for use, and could make a decision on 20 or more by Friday, the Associated Press reports.
Stars don't tend to go quietly, and the most massive of them all create a supernova explosion 50 to 100 times brighter than normal. Now astronomers have confirmed the existence of rare but huge stars that contain 200 times the mass of our sun, after spotting one unusually bright cosmic explosion in 2007.
While the fate of America's Yucca Mountain appears to be sealed, Finnish company Posiva is moving forward with a cutting-edge nuclear waste storage facility that it claims will safely store radioactive waste in drums deep in the ground for 100,000 years. While challenges abound, a green light from the Finnish government expected by 2012 will make the site on Finland's Olkiluoto Island the first permanent nuclear waste repository in the world, opening the door for more to follow.
So far, the search for extraterrestrial life beyond our solar system has focused on finding Earth-like planets. And sure, planets are great, since we know at least one of them harbors life. But David Kipping of the Harvard-Smithsonian Center for Astrophysics thinks that search might be a tad too narrow. In a new paper, Kipping described how current technology can be re-tasked to search for another life-bearing body: moons.
Plasma plays quite a large role in the universe, making up the high-energy centers of stars like our sun. But researchers are finding that plasma can carry out very small tasks just as well, like killing MSRA and other drug-resistant bacteria both on the skin’s surface and in chronic, non-healing wounds.
A few weeks ago we wrote about the naked mole rat, a repugnant little subterranean creature possessing a unique immunity to cancer. Now it turns out that the hardy little rodents are resistant to strokes as well, a finding that may help researchers figure out better treatments for brain injuries arising from heart attacks and strokes.
