Fifty years later, the same flight takes longer. Why?

Fifty years ago, American Airlines’ flight from New York to Los Angeles took 5 hours and 43 minutes. The same flight is 6 hours and 27 minutes today. Wendover Productions examines why planes don’t fly faster in this interesting video. (more…)

Healthcare facilities widely compromised by Medjack, malware that infects medical devices to steal your information

The healthcare industry is a well-known information security dumpster fire, from the entire hospitals hijacked by ransomware to the useless security on medical devices to the terrifying world of shitty state security for medical implants — all made worse by the cack-handed security measures that hospital workers have to bypass to get on with saving our lives (and it’s about to get worse, thanks to the Internet of Things > ).

The strawberries in this photo are blue

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!

Artificial sweeteners be damned; these naturally occurring, safe proteins are thousands of times sweeter than sugar

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…)

How Eratosthenes calculated the circumference of the Earth in 200 BC

High school teacher Joe Howard made another excellent math video. This time, he shows how Eratosthenes calculated the circumference of the Earth in 200 BC. In one of the dopest displays of critical thinking in history, Erotosthenes estimated the circumference of the Earth. All he had was a pole, the sun, knowledge of a famous well in Egypt, and potentially money to pay someone to walk the distance between two cities. This story demonstrates the beauty of trigonometry.

Nearby star has 7 "Earthlike" planets

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

Germans warned to DESTROY Cayla, network-connected doll that spies on children

It’s called Cayla , it’s about a foot tall, and it can be used to listen to and talk to the child playing with it. But who is doing the listening? Anyone in Bluetooth range, reports Germany’s Federal Network Agency (Bundesnetzagentur). An official watchdog in Germany has told parents to destroy a talking doll called Cayla because its smart technology can reveal personal data. … The Vivid Toy group, which distributes My Friend Cayla, has previously said that examples of hacking were isolated and carried out by specialists. However, it said the company would take the information on board as it was able to upgrade the app used with the doll. But experts have warned that the problem has not been fixed. The Cayla doll can respond to a user’s question by accessing the internet. For example, if a child asks the doll “what is a little horse called?” the doll can reply “it’s called a foal”. Watch the BBC’s video of Cayla, in its squeaky, sinister voice, say “I’ve been hacked to say all sorts of scary things.” https://www.youtube.com/watch?v=U0Y2KUN6XPM Cayla was on Boing Boing last year when the FCC received complaints about it. Cayla is on Amazon for $45 . It’s so easy to hack that everyday YouTubers are at it! https://www.youtube.com/watch?v=EvMb_TusPPs
