Literally a revolutionary bridge in this case–i.e., not a bridge that revolutionized engineering, or anything like that, but a bridge that was built by continental soldiers during the American Revolution. I’d not heard of it before. Sometimes I wish I wrote a history column instead of a science column–my favorite part of researching many of …
Acronym of the day
Nanoscale polymer beads, first developed as sensors to explore and monitor cellular processes, now hold promise for diagnosing and treating cancer. Excellent news, bravo, etc. But that’s not the main reason I’m blogging about it. I was just taken with the acronym they come up with for these little beads: PEBBLEs. Catchy, eh? It stands …
The next space prize
Following in the footprints of the X-Prize, NASA has announced its first Centennial Challenges. The Tether Challenge calls on inventors to create a material light enough and strong enough to be part of space elevators. The Beam Power Challenge is designed to encourage inventors to find a way to wirelessly beam a robot enough power …
Biological warfare, WWII-style
Remember when I blogged about the time the Japanese bombed Saskatchewan? Here’s a story about another wartime Japanese scheme–to drop rats and insects infected with bubonic plague, cholera, typhus and other diseases on U.S. cities, using submarine-borne bombers. Seems they’ve found one of the subs. (Nothing ever came of the plan.)
The replicating replicator
One of the futuristic inventions of the Star Trek universe is the replicator, a device that can make just about anything: such as “Tea, Earl Gray, Hot.” Replicators aren’t in the offing, but the next best thing is: a self-copying rapid prototyping machine. The idea of a machine that can make a variety of objects, …
