"Authorities, including the FBI, questioned a New Boston, Texas, man Thursday night in connection with an investigation of ricin-laced letters sent to government officials, including President Barack Obama," KSLA-TV in Shreveport, La., reports.
A construction worker paints walls at the Maryland Proton Treatment Center in Baltimore. Each of the center's five rooms will contain a massive piece of equipment that will rotate around a cancer patient to deliver a special kind of radiation.
When it comes to reining in health care spending, it still seems like each hospital administrator thinks the guy at the other hospital should do it.
Hospitals are still racing to offer expensive new technology — even when it hasn't been proved to work better than cheaper approaches. Case in point: proton beam therapy, a high-tech radiation treatment for cancer.
When you pick up a cut of beef at the store, would you like to know that animal's life history? The technology to do this does exist — at least in Michigan, where the state requires all cattle to carry electronic ear tags. It's the only state that requires such tags.
Michigan's cattle-tracking system was forced on farmers because of a crisis. Fifteen years ago, cattle in part of the state started catching tuberculosis from wild deer.
The Transportation Security Administration has told Congress that it's finished retrofitting airport scanners to blunt a widely criticized technology that shows graphic detail of a passenger's body as he or she goes through security checkpoints.
It might come as a surprise that for centuries the French have been sans a term for "French kiss."
But, voila! The newest edition of the Petit Robert 2014 dictionary has rectified that with a new verb — "galocher," meaning "to kiss with tongues." It's a clever derivation of la galoche, a word for an ice-skating boot, and so evokes the idea of sliding around the ice — or the lips and tongue.
U.S. shot putter Adam Nelson has been awarded a gold medal from the 2004 Athens Olympics, after his rival at those games, Yuriy Bilonog of Ukraine, was stripped of the victory last December for violating doping rules. The International Association of Athletics Federations and the International Olympic Committee made the change official Thursday.
NASA's Mars rover Curiosity used its Radiation Assessment Detector (RAD) to measure radiation exposure on the way to Mars. Now, it's recording similar data on Mars' surface. This image is a composite self portrait taken on Feb. 3, 2013.
There was great fanfare when the Mars Science Laboratory launched in November 2011, and again when its precious cargo — NASA's Mars rover Curiosity — touched down on the red planet in August 2012.
The eight months in between had drama of their own. Curiosity was constantly bombarded with radiation as it traveled through space — high-energy protons thrown out by the sun, and galactic cosmic rays slicing through the solar system from distant supernovas.
In the more than eight years since it was written, the open-source operating system Ubuntu's "Bug #1" has been seen as a rallying call. After all, the bug's title is "Microsoft has a majority market share."
But the entry was officially closed Thursday, partly because the "broader market has healthy competition" as Ubuntu leader Mark Shuttleworth writes in his comments on closing the bug today.
Sometimes the most powerful and transformative technologies emerge by accident, an unintended consequence of other developments. When this happens, the scope and power of the new technology can't be fully appreciated until after we have embedded it in our culture.
