*Microsoft employee Carl Greninger helped a team of young students build a working nuclear reactor in his garage. He hopes the project can inspire a passion for physics in students around the country.*

REDMOND, Wash. – Sometimes you have to smash a few atoms to excite people about science.

So says Carl Greninger, a program manager in Microsoft IT Operations by day and full-fledged physics fanatic by night. That’s why he decided to help some young students get hands-on experience with something they couldn’t find in their classrooms: a working thermonuclear reactor.

For the past year, a group of local students – some as young as 13 years old – have met at Greninger’s garage every Friday night to build a type of fusion reactor known as a Farnsworth–Hirsch Fusor. Dubbed IEC-9000, their machine has been fusing atoms and producing neutrons since May. It cost about as much as a high-end SUV, weighs 1,400 pounds, and generates temperatures hotter than the surface of the sun. (more…)

NASA Research Confirms it’s a Small World, After All

A NASA-led research team has confirmed what Walt Disney told us all along: Earth really is a small world, after all.

Since Charles Darwin’s time, scientists have speculated that the solid Earth might be expanding or contracting. That was the prevailing belief, until scientists developed the theory of plate tectonics, which explained the large-scale motions of Earth’s lithosphere, or outermost shell. Even with the acceptance of plate tectonics half a century ago, some Earth and space scientists have continued to speculate on Earth’s possible expansion or contraction on various scientific grounds.

Now a new NASA study, published recently in Geophysical Research Letters, has essentially laid those speculations to rest. Using a cadre of space measurement tools and a new data calculation technique, the team detected no statistically significant expansion of the solid Earth. (more…)

*Four Quarters, Four Screens: Catch Yahoo! Fantasy Football on TVs, Tablets, Mobile Phones and Computers*

SUNNYVALE, Calif.–(BUSINESS WIRE)— Yahoo! named Green Bay — home to the reigning Super Bowl champions — the Official Yahoo! Sports Fantasy Football City of 2011, with one in 29 Yahoo! Sports Fantasy Football players per capita during the 2010 season. Yahoo! also announced that its No. 1 ranked fantasy football experience will be available across four screens in time for the first NFL regular season game.

Yahoo! Sports Fantasy Football is the No. 1 fantasy football platform in the industry — and not just in Green Bay. During the NFL season, Yahoo! Fantasy Sports alone receives more visitors than all of NYTimes.com, and more time is spent playing Yahoo! Sports Fantasy Football than is spent on sites such as NFL.com, FOX Sports, CBS Sports, NYTimes.com, Amazon.com, Netflix.com, Disney Online, and Wikipedia.* Fans can sign up at https://sports.yahoo.com/fantasy. And in 2011 Yahoo! Sports is ensuring that its games capture the changing trends as to how users access information by providing them with access to their teams regardless of device or location.

First Data from Daya Bay: Closing in on a Neutrino Mystery

*Berkeley Lab researchers are leaders in an international effort to close in on neutrino mass*

Some of the most intriguing questions in basic physics focus on neutrinos. How much do the different kinds weigh and which is the heaviest? The answers lie in how the three “flavors” of neutrinos – electron, muon, and tau neutrinos – oscillate or mix, changing from one to another as they race virtually without interruption through unbounded reaches of matter and space.

Three mathematical terms known as “mixing angles” described the process, and the Daya Bay Reactor Neutrino Experiment has just begun taking data to establish the last, least-known mixing angle to unprecedented precision. China and the United States lead the international Daya Bay Collaboration, including participants from Russia, the Czech Republic, Hong Kong, and Taiwan. U.S. participation is led by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). (more…)
