Star Power: The Promise of Nuclear Fusion

sun470

Not getting enough rays these days? Never fear: engineers may be on the brink of creating our own miniature star.

While solar power is a key part of the global clean energy strategy, scientists are pursuing other, perhaps more promising, methods to produce fuel sources. One such possibility is the recreation of fusion, a powerful nuclear reaction that only occurs naturally on the blazing surfaces of stars.

Happy 50th, Laser!

Scanner

This year marks not only the beginning of a new decade, but also the 50th anniversary of the creation of the laser. Though we tend to take them for granted, lasers have revolutionized the way we live. They allow us to surf the web, watch movies on DVD, and scan barcodes at the grocery store; they also enable eye surgery, study the planet, target weapons, and facilitate worldwide communication. And, of course, can create dazzling displays of light for your band’s next performance (cool laser videos after jump)

Who Is Sabotaging the LHC?

“For those of us who believe in physics, this separation between past, present and future is only an illusion.” –Albert Einstein

Perhaps you’ve heard of the Large Hadron Collider (LHC for short): the world’s largest, most advanced particle accelerator, a circular underground tunnel that stretches about 17 miles in diameter. Located on the border of France and Switzerland, the collider is operated by the European Organization for Nuclear Research (also known as CERN) and took over 15 years and $9 billion to build.

Engineer Searches for Lost Leonardo

Battle of Anghiari sketch by Reubens

Maurizio Seracini, an engineering professor at the University of California, San Diego, may soon be on his way to uncovering a long-lost mural by Leonardo DaVinci. Seracini believes the painting is hidden beneath another fresco in ceremonial hall of the Palazzo Vecchio in Florence. With permission from Italian government, he will soon be able to proceed with his search and use specially developed devices (including one that bombards the fresco with neutrons) to look for traces of DaVinci’s hand.
