The dinosaur’s jaw was lined with at least 1,000 teeth with coarse surfaces perfect for pulverizing plants. U. kuukpikensis belongs to the hadrosaur group of duck-billed dinosaurs. It was 25 to 30 feet long, six or seven feet high at the hip, and probably covered with scales.”

“With timelapse cameras, specialists recorded salt water being excluded from the sea ice and sinking. The temperature of this sinking brine, which was well below 0C, caused the water to freeze in an icy sheath around it. Where the so-called “brinicle” met the sea bed, a web of ice formed that froze everything it touched, including sea urchins and starfish.”

“This effort appears to have backfired for the organization—whose mission is to raise awareness about how certain environmental exposures may be linked to autism—since the study SafeMinds supported showed a link between autism and vaccines does not exist.

We’ve begun to fit the machines into an age-old technique we evolved thousands of years ago—“transactive memory.” That’s the art of storing information in the people around us. We have begun to treat search engines, Evernote, and smartphones the way we’ve long treated our spouses, friends, and workmates.”

Unlike all other spoken languages, a whistled form of Turkish requires that “speakers” rely as heavily on the right side of their brains as on the left side, researchers have found.”

“Instead of using ‘right’ and ‘wrong’ to describe Standard American English versus African-American English, Craig’s model uses ‘formal’ and ‘informal’ designations, so there’s no judgment attached to either language. One isn’t ‘better’ than the other per se, it’s all about when it’s appropriate to use one form or the other. It’s ‘this is how you talk in school,’ rather than ‘don’t talk like that.’ Craig calls it ‘a slight change’ that makes a big difference in kids’ attitudes about their own language.

What would Earth’s skies look like with Saturn’s rings? Awesome, gorgeous renderings.

And one (more) big science-based reason why everyone should be able to make a comfortable living wage:

If just one Einstein right now is working 60 hours a week in two jobs just to survive, instead of propelling the entire world forward with another General Theory of Relativity… that loss is truly incalculable. How can we measure the costs of lost innovation? Of businesses never started? Of visions never realized?”
