We can’t see dark matter, but scientists have made the largest map yet of the invisible material that helps make up the universe. Researchers used a dark energy camera and a large telescope to create a color-coded chart of just a small part of the cosmos. Jeffrey Brown talks to Sean Carroll of the California Institute of Technology about how they did it and why it matters. Continue reading
After two years of upgrades and repairs, CERN’s Large Hadron Collider in Geneva, Switzerland fires up again this month. This time it’s moving at twice the energy, looking for dark matter and exotic new particles.
At the bottom of a nickel mine near Sudbury, Ontario, scientists at one of the world’s most sophisticated particle physics observatories are investigating one of the biggest mysteries of the cosmos: What is dark matter? Science correspondent Miles O’Brien helps to shed some light on the research at SNOLAB. Continue reading
In a New York City classroom, teachers use rap songs to teach complex science. Playlists are used as a metaphor to convey natural selection, and students compose raps songs to reinforce concepts. Ray Suarez reports on the effectiveness of this strategy and interviews hip-hop legend (and science geek) GZA of the Wu-Tang Clan. Continue reading
Disappointed scientists learned this week that the Large Hadron Collider — the most powerful particle collider ever built — will be shut down until next spring after an electrical glitch sparked a helium leak in the machine’s 17 miles of tunnels. Continue reading
In an effort to understand some of the basic tenets of physics, scientists and engineers fired a beam of protons around a 17-mile tunnel Wednesday — a successful first run for the world’s most powerful particle accelerator. Brian Greene, host of the PBS series “Elegant Universe,” explains the feat. Continue reading
Scientists fired a beam of protons around a 17-mile, multi-billion dollar track today — a successful first run for the world’s most powerful particle accelerator. Continue reading
