Blue light smells like bananas -- if you're a genetically modified fruit fly.
Scientists in Germany figured out how to modify fruit fly larvae so they can "smell" light, encouraging them to move toward it, rather than away from it like they normally would. Before you get excited about actually smelling Skittles when you see a rainbow, however, bear in mind that the fruit fly larvae are much easier to manipulate than humans.
In the next five years, the world will need a hundred-fold increase in nano workers — the people who will build nanomaterials and develop new uses for them. In Colombia, some of these workers might very well come from the slums. At least according to one nano educator.
Add drywall to the growing list of toxic imports from China. Today a report from the largest investigation in the history of the US Consumer Product Safety Commission has cited 10 Chinese manufactures as sources of sulfur-laden drywall found in thousands of homes constructed in the United States between 2005 and 2009, when a post-Katrina building boomed created a run on drywall and forced builders to seek out new suppliers.
The loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?
According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites.
When the J. Craig Venter Institute announced last week that it had created the first "synthetic cell," whose genome had been synthesized artificially one base pair at a time, Venter himself mentioned that the genetic code had been tagged throughout with watermarks that identify it as man-made rather than natural code. Now we're hearing that those watermarks weren't arbitrary.
This summer, Noah's Ark Water Park in Wisconsin Dells, Wisconsin, opens the country's only looping waterslide. The Scorpion's Tail gives you the thrills of a roller coaster without having to strap to a track (or wear a shirt)—and it uses sophisticated engineering to keep you secure as you slip any which way.
Riders stick to the walls because the loop travels a tilted angle, not a straight-up-and-down line that could drop people on their heads. Then there's the computerized control system, exit hatch and host of sensors to make sure riders splash out intact.

All vertebrates have tiny structures called semicircular canals inside their ear that help them to maintain balance even when their heads are bobbing around vigorously. That’s why rodeo bulls can buck wildly and not fall over.
For two years, Charles Okeke, 43, was just another patient confined to a hospital while awaiting a human heart transplant. Now, he's the country's first test subject for a battery-operated, backpack-sized console, called the Freedom Driver, which will power his artificial heart and allow him to go home for the first time in two years.
NASA has just announced the details of its next Mars mission, Curiosity, which will take off between November 25 and December 18, 2011. Curiosity is scheduled to land on Mars between August 6 and August 20, 2012. The rover, also known as the Mars Science Laboratory, will study the Martian surface for conditions favoring the development of microbial life. NASA plans to let Curiosity explore Mars for a full Martian year, or two Earth years.
It's a shotgun wedding, officiated by a robot matador, the cloned baby bull that brought them together resting comfortably in a newly invented incubator backpack. And the roaches, my God, the roaches. Only in the future.
