23andMe Is Suing Ancestry Over Some Pretty Ancient IP
Click:comparer taille Heredity is so hot right now. In 2017, the number of people who who’ve had their DNA analyzed for the purposes of tracing their genealogy doubled to more than 15 million.

The Math Behind Gerrymandering and Wasted Votes
Imagine fighting a war on 10 battlefields. You and your opponent each have 200 soldiers, and your aim is to win as many battles as possible. How would you deploy your troops? If you spread them out evenly, sending 20 to each battlefield, your opponent could concentrate their own troops and easily win a majority…
Peter Diamandis Is the Latest Tech Futurist Betting on Anti-Aging Stem Cells
Peter Diamandis’ ambitions have always been too big for the measly planet onto which he was born. The serial entrepreneur built his first dozen companies as technological launch pads for future space colonies.

How Much Energy Can You Store in a Rubber Band?
How much energy can you store in a rubber band? Obviously, the answer depends on the size of the rubber band. I'm talking about, of course, the energy density or specific energy of an energy storage material. The energy density is defined as the energy per unit volume, and the specific energy is the energy…
To Fix the Space Junk Problem, Add a Self-Destruct Module
Humans have gotten pretty good at launching stuff into space—but way less good at getting stuff back down. Up in lower Earth orbit, along with a thousand-plus productive satellites, there are many more slackers: space junk, cosmic trash, garbage of the highest-orbiting order. According to the European Space Agency’s latest statistics, there are about 29,000…
Why No Gadget Can Prove How Stoned You Are
If you’ve spent time with marijuana—any time at all, really—you know that the high can be rather unpredictable. It depends on the strain, its level of THC and hundreds of other compounds, and the interaction between all these elements. Oh, and how much you ate that day. And how you took the cannabis. And the…
The Physics of the 69-Degree Intersection That Kills Cyclists
Sometimes when I see an awesome analysis on the internet, I just want to make it more awesomer. Really, this should be everyone's goal on the internet—either make stuff or make it more awesome. In this case, it's a post from Singletrack (and also covered by Boing Boing) looking at a particular crossroad in the…
AI Learns a New Trick: Measuring Brain Cells
In 2007, I spent the summer before my junior year of college removing little bits of brain from rats, growing them in tiny plastic dishes, and poring over the neurons in each one. For three months, I spent three or four hours a day, five or six days a week, in a small room, peering…
California’s Water Whiplash Is Only Going to Get Worse
In December 1861, as a California drought was wearing into its fifth year, farmers on the West Coast were all asking for one thing for Christmas: rain. And boy did they get it. For 43 days rain and snow fell across the state, causing rivers to surge their banks, turning the 300-mile long, 20-mile-wide Central…
