Two years ago, Marla Geha, a Yale University astronomer, Joshua Simon from the Carnegie Institution of Washington, and their colleagues discovered something unusual while studying with the Keck II telescope and information for the Sloan Digital Sky Survey. Their observations turned up a contrasting group of stars which all appeared to be moving in unison [...]
If you’re looking for another popcultury podcast to listen to, here’s a link to the most recent episode of the Caustic Soda Podcast, featuring me. They wanted to talk about comets, meteorites and asteroids, so they thought I’d somehow be able to elevate the conversation. Did I? You be the judge. Here’s a link to [...]
Scientists in the Japanese-European ASACUSA experiment at CERN reported today that they have measured the mass of the antiproton with nearly the same accuracy as scientists have measured the mass of its partner particle, the proton. This will help scientists seeking to understand why our universe is dominated by matter when the big bang is [...]
Scientists of the CDF and DZero collaborations at Fermilab continue to increase the sensitivity of their Tevatron experiments to the Higgs particle and narrow the range in which the particle seems to be hiding. At the European Physical Society conference in Grenoble, Fermilab physicist Eric James reported today that together the CDF and DZero experiments [...]
Experiments at the Large Hadron Collider have yet to find signs of supersymmetric particles, scientists announced at the European Physical Society conference this week in Grenoble. But physicists will significantly improve their knowledge of SUSY in the coming year through indirect methods, which could include the discovery of the Higgs boson. “For supersymmetry, this is [...]
This story first appeared on July 25 in Fermilab Today. A new result from Fermilab’s DZero experiment was announced Saturday at the European Physical Society conference in Grenoble, France, studying the production of the top quark and its antimatter counterpart, the antitop quark, in proton-antiproton collisions. This result, called top quark forward and backward asymmetry, [...]
Fermilab issued the following press release on July 20. Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0). This particle contains three quarks: a strange quark, an up quark and a bottom quark (s-u-b). While its existence was predicted [...]
Hundreds of physicists from around the world are making plans to shoot the world's most intense beam of neutrinos from Illinois, underground through Iowa, all the way to a former gold mine in South Dakota. And Iowa State University's Mayly Sanchez is part of the research team.
