Farewell to the Tevatron

The top U.S. particle collider, now eclipsed by a more powerful European machine, will be switched off September 30

Inside the Tevatron; the Human-Computer Interface; DNA Computing.

In this episode, Scientific American editor Mark Alpert talks about his trip inside the Tevatron, the world's most powerful particle accelerator, at the Fermi National Accelerator Laboratory, and the future of the Tevatron, specifically for neutrino research. Scientific American senior writer Wayt Gibbs reports on the recent CHI2006 conference. CHI is for computer human interface, and the conference is the largest annual meeting of computer scientists who study and invent the ways that humans and computers talk to each other. Wayt interviewed Ed Cutrell, from Microsoft Research's Adaptive Systems Interaction Group, and reviews some of the subjects he came across at the meeting. Finally, computer scientist and chemist Ehud Shapiro talks about DNA computers and his article on the subject in the May issue of Scientific American. Plus, test your knowledge about some recent science in the news.

Budget crunch could prematurely shutter Tevatron

It has been a rough 2011 for the physicists working on the Tevatron, the top particle collider in the U.S. and the second most powerful in the world after Europe's Large Hadron Collider.

Fermilab says: "Hey wait, we're in the Higgs hunt, too!"

It looks like the Large Hadron Collider (LHC) may have some competition in its search for the much-anticipated Higgs boson, the source of mass.

Yesterday CERN, the European particle physics lab, announced that on September 10 it would begin shooting protons around the full 27 kilometers (17 miles) of the circular LHC—the most powerful particle accelerator ever built—building up to collisions with a second, opposing beam in subsequent months.
