On August 20, 1977, the counter-intuitively named Voyager 2 was the first of the twin Voyager probes to launch (Voyager 1 launched 16 days later). This week, after 41+ years and over 11 billion miles traveled, Voyager 2 joins its sister beyond the reaches of our sun’s solar wind in interstellar space.
Voyager 2 took the scenic route out of town, visiting all four of our solar system’s gas giants, and racking up an impressive list of mission accomplishments in the process. Now, it’s final mission is to send back data about the forces of interstellar wind — something Voyager 1 couldn’t do after its plasma-measuring instruments failed way back in 1980.

No longer. We now live in a time where a camera phone and attendant app can diagnose this condition in seconds, at higher rates of accuracy than your doctor.
What do Honda, NASA’s Jet Propulsion Laboratory at CalTech and toothpaste have in common? — fluoride. (Obvious, right?) Besides being a killer Tribond answer, fluoride may be the answer to lighter, more stable, cooler-running and longer-lasting battery technology than the current standard of Lithium-Ion.
Did you know that spider’s silk is “as strong as steel and light as a feather”? I must confess that I did not until coming across this JSTOR “Cabinet of Curiosities” piece about everyone’s least favorite weaver. (Honestly, I thought such references were just the product of the Spider-Man comic book lore.) If you aren’t wigged out by the prospect of working closely with 1.2 million large spiders, have 79 friends willing to help, and 8 years to spend on the project, you too can turn out a museum-quality garment like this cape here:
