By choosing Nobel-prizewinning physicist Steven Chu to head the Department of Energy (DoE), US President-elect Barack Obama has sent a clear message: solving climate issues in a world dependent on fossil fuels will depend on science coming up with new energy technologies.

LHC further delayed

There's little holiday joy for eager high-energy physicists waiting on their newest toy. A report out today says that the Large Hadron Collider (LHC), the world's most powerful particle accelerator, located at CERN near Geneva, Switzerland, will not start before July 2009, and repairs are set to cost up to 35 million Swiss francs

French Try Plane Technology in Artificial Heart

In the race to build a better artificial heart, French scientists have turned to technology from satellites and airplanes to create a heart that they say responds better to the human body. So far, the new device, shown at a news conference in Paris on Monday, has only been tested in animals. Its makers hope it might one day help people survive without needing a human heart transplant.

The maker of this artificial heart is a subsidiary of the European Aeronautic and Space Defense Company (EADS), but this isn't a matter of fluid dynamics

CERN collider takes five

Some of the superconductors in the Large Hadron Collider have heated up and leaked helium into the collider tunnel. The collider has been shut down so that repairs may be made, a process that will take months as the machinery is slowly heated to a workable temperature and then cooled back down again. The machine operates at a temperature only a few degrees above absolute zero.

The future of physics is off to an auspicious start

Well, they fired up the controversial Large Hadron Collider in Switzerland, and so far the universe hasn't imploded. Science is referring to the machine's debut operation as an out-of-the-park home run. The New York Times is calling for champagne. Yesterday morning, researchers passed a beam of particles all the way through both rings, like Olympic athletes taking a victory lap.

German Physicist to Head CERN

The governing council of CERN, Europe's particle physics lab near Geneva, Switzerland, today tapped German particle physicist Rolf-Dieter Heuer to be its next director general. Heuer, 59, will take the reins for a 5-year term beginning in January 2009, half a year after CERN's Large Hadron Collider (LHC) is due to be completed. "Scientifically, my top priority is to get the LHC efficiently running and get the data analysis moving," Heuer told ScienceNOW. He has described the position as "probably the best job in physics research today."
