And this is how we learn that the same data can be used to come to opposite conclusions.
It's so easy! Except for the fact that literally nobody else has ever gotten it right.
Tesla now logs data for all test drives taken by journalists. This could be a scarily exposed new world for "creative" reviewers, in which fudging numbers could be a thing of the past.
Researchers at the German Cancer Research Center in Heidelberg have discovered a particular molecule, named Dickkopf-1 or Dkk1, that seems to have a positive effect on cognition in the elderly. Typically, as humans (and rats) age, they produce fewer neurons, which inhibits cognitive abilities. But when Dkk1 is blocked, older rats tested just as well as younger rats on memory and recognition tests.
Draw a Tyrannosaurus rex from memory, right now. It's probably wrong in a very significant way.
Guess the species (either common or Linnaean) by tweeting at us--we're @PopSci

A persistent mystery for art historians and especially students of 20th century art might seem small at first: what kind of paint did Picasso use? But in fact it's a very big shift--Picasso was thought to have been one of the first painters to switch from traditional oil paints to common house paint, which is quick-drying and smooth and allows for a very different style (it doesn't show brush-marks, for example). Now, the Art Institute of Chicago and the Argonne National Laboratory teamed up and used hard x-ray nanoprobes to analyze Picasso's paint at the molecular level.
There's a great little post on XKCD examining the speeds of data delivery--especially useful given today's confirmation that Saturday USPS delivery is shutting down. It's long been the case that if you need to send someone a lot of data--like, a few hundred gigabytes--it's faster to just FedEx the hard drive. But internet throughput is growing steadily, whereas FedEx's delivery capabilities have a distinct cap--so when will the internet truly be faster than FedEx? Read the post here.
It's not a tablet, despite its looks. But it is a gorgeous, impressively powerful, and very very small Windows 8 laptop--one of the best on the market.
I repeatedly dried my hands with the best hand dryers in the world. By the end, my hands were very dry.
Got a twitch in your eyelid, arm, or leg? Wondering where the hell it comes from and how to get rid of it? Answers within.
Curious about what a 900mph ping-pong ball does to a piece of wood? The answer is here.
Would you trust the testimony of a witness who admitted to being drunk while observing a crime? You should.
Take a look at the submerged backbone of the internet.
United States Energy Secretary Steven Chu, a Nobel Prize winner and fierce proponent of alternative energy, announced today that he will resign his governmental position and return to academia. Chu was the director of the Lawrence Berkeley National Laboratory and a professor at the University of California, Berkeley when appointed Energy Secretary. He is well-known for his advocacy of alternative energy as a method of correction against climate change, and has speculated on future energy possibilities based on high-glucose tropical plants. During his time as Secretary, renewable energy use in the US doubled. Chu says he will return to academia in California. [via CNN]
