Earth's 6-Year Twitch Changes Day Length

Periodic wobbles in Earth's core change the length of a day every 5.9 years, according to a study published today (July 10) in the journal Nature. Full story

Giant Particle Storage Ring Set for 3,200-Mile Trek

A particle storage ring spanning 50 feet (15 meters) in diameter is set to go on a long cruise this summer, from New York to Illinois, where it will get a new life capturing ultra-rare particles in a magnetic field. Full story

Earth's Core 1,000 Degrees Hotter Than Expected

Earth's internal engine is running about 1,000 degrees Celsius (about 1,800 degrees Fahrenheit) hotter than previously measured, providing a better explanation for how the planet generates a magnetic field, a new study has found. Full story

The Unparticle May Lurk in Earth's Mantle

It's a good time to be a particle physicist. The long-sought Higgs boson particle seems finally to have been found at an accelerator in Geneva, and scientists are now hot on the trail of another tiny piece of the universe, this one tied to a new fundamental force of nature. Full story
