July 4, 2012breaking: Photoshop contest: Where have you seen the Higgs?Early this morning, scientists on experiments at the Large Hadron Collider announced that they have observed a new particle that may eventually prove to be the Higgs boson. Have you spotted the mysterious particle? Submit your photographic evidence!

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.

June 20, 2012breaking: Guests take a peek inside Tevatron experimentsIn connection with a symposium celebrating the Tevatron, Fermilab scientists gave special tours of the collider's two experiments. A reporter from Naperville Community Television Channel 17 took the opportunity to visit the detectors and filed this report.
