I’ve got a new article up at newly relaunched Quanta magazine (it was formerly Simons Science News) on the ongoing hunt for dark matter — the stuff that makes up roughly one-quarter of all the mass in the universe. Also check out the excellent piece by Carl Zimmer: Galloping toward complexity through a meandering fitness landscape. And speaking of dark matters, Matt Francis has a message for you: Please don’t use “dark matter” to mean “something we don’t understand.”
There was some great stuff over at Nautilus this week, which is currently all about Transport. Traffic Ghost Hunting: Phantom traffic jams are when the biggest problem with traffic is nothing at all. Things you can call “rogue”: vagrants, wandering rabid animals, Sarah Palin, pirates. Things you can’t: exoplanets.

It’s about time! The drip finally dropped! Trinity College experiment succeeds after 69 years — not to be confused with a similar experiment in Australia. “So far, technical glitches have meant that the Australian experiment has never been caught dripping on camera.”
Fourth-string Jaegers: Earth’s last hope? “Let’s hope it doesn’t come to that.” Also on the Pacific Rim front, Deep Sea News explored a couple of pressing questions: How may people does a Kaiju need to eat every day? (“The short answer is not as many as you think.”), followed by How much urine can a Kaiju produce? And Fact or Fictional Discussed Pacific Rim and the Reality of Giant Robots.

Elon Musk Thinks He Can Get You From NY to LA in 45 Minutes with his proposed design for a Hyperloop — an updated version of a pneumatic transport tube. But is it just hype? Gizmodo thinks the Biggest Obstacle for Musk’s Hyperloop Might Be Tunnels. Then again, Musk has a pretty solid track record for making innovative advances — including shortening the time to recharge an electric vehicle in just five minutes, on a par with how long it takes to fill up a standard gas-powered car. Here’s a bonus video: How a Tesla Model S Electric Car is Made (via Laughing Squid):

“In 1960′s France, Bezier popularized his eponymous curves (actually invented much earlier) by using them to design cars for Renault. Around the same time and place Picasso drew his famous line drawings. ” That’s mathematician Brie Finegold reminiscing about her teenaged fascination with drawing curves and their relation to Picasso’s art: String Art, Bezier Curves, Picasso, and me. And here’s the original post by Jeremy Kun that inspired it: “There is one obvious way to consider Picasso-style line drawings as a mathematical object: the Bezier curve.”
