This picture has NO red pixels. Great demo of color constancy (ht Akiyoshi Kitaoka) pic.twitter.com/pZHvbB6QHE — Matt Lieberman (@social_brains) February 27, 2017 My daughter send this photo to me. I put it in Photoshop to check. The “reddest” part I could find using the eyedropper had an RGB value of 153/181/182. So technically there is some red in the image, but here is what 153/181/182 looks like: Not very red!

KSU plant biochemical geneticist Raj Nagarajan describes the properties of Thaumatin, Monellin and Brazzein, all found in west African plants that are generally considered safe for consumption; each is a protein, and they are, respectively, 1,000x, 2000x, and 3000x sweeter than sugar. (more…)

TRAPPIST-1 is a star that’s 39 light years away from us. The journal Nature reports that it has seven warm, Earthlike planets orbiting it. From Washington Post : The discovery, reported Wednesday in the journal Nature, represents the first time astronomers have ever detected so many terrestrial planets orbiting a single star. Researchers say the system is an ideal laboratory for studying alien worlds and could be the best place in the galaxy to search for life beyond Earth. “Before this, if you wanted to study terrestrial planets, we had only four of them and they were all in our solar system,” said lead author Michaël Gillon, an exoplanet researcher at the University of Liège in Belgium. “Now we have seven Earth-sized planets to expand our understanding. Yes, we have the possibility to find water and life. But even if we don’t, whatever we find will be super interesting.” Images: NASA/JPL-Caltech

The GPD Pocket is a wee laptop with a 7″ high-dpi touchscreen display and an enticing $399 price tag. It’ll be light on power, with an Intel Atom CPU, 8GB of RAM and a 128GB SSD, but promises about 12 hours on a charge and two USB ports, one of them type C. There’s a ThinkBook-style tracknipple in lieu of a trackpad. It’ll run Ubuntu or Windows 10 and, somehow, they managed to sneak a headphone jack on there. (more…)

One of the two women suspected of assassinating Kim Jong-un’s brother wore a shirt with “LOL” written on it. CCTV images released by Malaysian authorities show the suspects lurking in Kuala Lumpur airport; reports variously have them using needles or a spray to poison Kim Jong-nam, who died en-route to hospital. In a scene out of a James Bond film, the toxic spray-wielding femme fatales targeted 45-year-old Jong Nam – the globetrotting black sheep of his North Korean ruling class family — in the airport’s departure hall on Monday morning. The women – believed to be North Korean agents – unleashed the noxious fumes in the face of Jong Nam as he waited for a flight to Macau, China. Jong Nam staggered to a receptionist, indicating that he was on the verge of passing out and suffering a mild seizure, police said. Nam would be running the hermit kingdom but for several embarrassing episodes (such as being arrested trying to visit Tokyo Disneyland on a false passport) that saw his younger brother rise in their now-dead father’s eyes.

John Collins holds the Guinness World Record for designing the farthest flying paper airplane. The plane, folded from a single piece of A4 paper, flew 69.14 meters in 2012. Harvard University made this video of Collins folding his masterpiece during a recent visit with Harvard’s design engineering graduate students. More designs at The Paper Airplane Guy .

Zuck That says, “Have you ever been on the Internet when you came across a checkbox that says “I’m not a robot?” In this video, I explain how those checkboxes (No CAPTCHA reCAPTCHAs) work as well as why they exist in the first place.” I mention CAPTCHA farms briefly, but the idea behind them is pretty straightforward. If a company wants to create an automatic computer program to buy 1,000 tickets to an event or make 1,000 email accounts, they can make a script that fills out the form one at a time, and when the program gets to a CAPTCHA, it will send a picture of it to a CAPTCHA farm where a low-wage worker will solve it and send the answer back to the computer program so that it can be used to finish filling out the form.
