November 5, 2012feature: Voyage to SNOLABA growing number of scientists are looking for ways to join a dream team of experiments in a unique laboratory a mile and a half underground in Ontario. There, they seek to solve some of the biggest mysteries in physics today, including the case of missing dark matter.

October 29, 2012signal to background: Dark-matter seekers get help from the DarkSideFilled with rare, low-radioactivity material, the DarkSide-50 experiment will have some of the lowest background rates of any dark-matter detector. That should help it detect highly sought-after dark-matter candidates called weakly interacting massive particles, or WIMPs.

October 19, 2012signal to background: Learning to play the dark matter boogieA growing suite of computational instruments is helping scientists determine how fast local concentrations of dark matter move, which in turn could help them cut in on the dance of dark matter particles.

October 2, 2012breaking: Panofsky Prize honors researchers' underground hunt for dark matterThe search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle Physics.

July 23, 2012breaking: Precious cargo: Dark matter experiment set to move undergroundFor the past two years, COUPP-4, a 4-kilogram bubble chamber experiment, has searched for signs of dark matter a mile underground at SNOLAB in Sudbury, Ontario. Now that experiment is about to get company – its big brother is moving in.
-
July 20, 2012breaking: Most sensitive dark-matter detector constrains search for WIMPsThe XENON collaboration announced this week that they detected no signs of potential dark matter particles during the last 13 months. Their results will be used to narrow the search for the unseen particles that scientists think make up most of the matter in the universe.

June 28, 2012breaking: Scientists discover that Milky Way was struck some 100 million years ago, still rings like a bellOur galaxy, the Milky Way, is a large spiral galaxy surrounded by dozens of smaller satellite galaxies. Scientists have long theorized that occasionally these satellites will pass through the disk of the Milky Way, perturbing both the satellite and the disk. A team of astronomers from Canada and the United States have discovered what may well be the smoking gun of such an encounter, one that occurred close to our position in the galaxy and relatively recently, at least in the cosmological sense.

February 1, 2012breaking: Calculating the universeSince 2000, the three Sloan Digital Sky Surveys (SDSS I, II, and III) have surveyed well over a quarter of the night sky, producing the biggest 3-D color map of the universe ever made. Now, scientists have used this visual information for the most accurate computation yet of how matter clumped together – from a time when the universe was only half its present age until now.

February 1, 2012signal to background: A brainy look at dark matterHave you ever sat in an open field at night, looked up at the vast number of stars and thought, “I bet an artificial brain would come in handy for making sense of all this”? You might if you were planning the best way for NASA to map the sky.
