Wired summarizes an egghead study for the rest of us. Parents may benefit from understanding that when they criticize their adolescents, adolescents may experience strong negative emotional reaction, may have difficulty cognitively controlling this emotion and may also find it challenging to understand the parent’s perspective or mental state. (From a study summarized in Wired.)
You see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat. You see between 20 and 32 color nuances: you are a trichromat, you have 3 types of cones…
What’s significant in this story is not that a computer can perform tasks more efficiently than a human, but that the computer in question is not deploying a pre-programmed strategy; it is instead teaching itself how to win. When IBM’s Deep Blue computer defeated chess grandmaster Garry Kasparov in 1997, and the artificially intelligent Watson…
I remember, as a kid, being thrilled by the images that came in from the Voyager flybys in the late 70s and 80s. I wrote a fan letter to NASA when I was about 11, and received a big stack of glossy publications on the Space Shuttle and commercial technologies spun off from NASA inventions.…
A chemist celebrates the liberal arts. Our culture has drawn an artificial line between art and science, one that did not exist for innovators like Leonardo da Vinci and Steve Jobs. Leonardo’s curiosity and passion for painting, writing, engineering and biology helped him triumph in both art and science; his study of anatomy and dissections…
Reading each other’s facial expressions is so important to our survival as a species that our brains are hardwired to respond to expressions on faces that aren’t even there. This adorable image — in which the galaxy cluster SDSS J1038+4849 seems to be smiling at the camera — comes courtesy of the Hubble Space Telescope. It was spotted…
A number of people who’ve seen NASA’s annual lunar phase and libration videos have asked what the other side of the Moon looks like, the side that can’t be seen from the Earth. This video answers that question. The imagery was created using Lunar Reconnaissance Orbiter data. A number of people who’ve seen NASA’s annual…
On this day in 1986, the Challenger space shuttle broke apart 73 seconds into its flight and plunged into the Atlantic Ocean. All seven of the Challenger astronauts, who had blasted off from Florida’s Kennedy Space Center, perished. One of the crew members, Christa McAuliffe, had won a nationwide NASA competition to be the first…
Sure, Saturn’s rings are cool, but the Earth is pretty awesome too, what with the water, the oxygen, the life, the chocolate. So let’s imagine just how awesome Earth would be if it also had rings. Ron Miller’s illustrations show various views of the earth with what that lucky planet Saturn has. —Ron Miller/Black Cat…
If the pre-1978 laws were still in effect, we could have seen 85% of the works published in 1986 enter the public domain on January 1, 2015. Imagine what that would mean to our archives, our libraries, our schools and our culture. Such works could be digitized, preserved, and made available for education, for research,…
These are straight vertical and horizontal lines. It’s your mind that’s twisted. Researchers at Barrow Neurological Institute made a Lego checkerboard and placed white and purple M&Ms on the squares in a way that makes the board appear to bulge. Illusion Chasers, Scientific American Blog Network.
Microchimerism most commonly results from the exchange of cells across the placenta during pregnancy, however there is also evidence that cells may be transferred from mother to infant through nursing. In addition to exchange between mother and fetus, there may be exchange of cells between twins in utero, and there is also the possibility that…
Idea for a scientist pull-cord doll: “Fashion is hard!” Very interesting in the light of this: I made a shirt for one of my close pals @mggtTaylor for his b’day. Did not expect this!! #shirtgate #shirtstorm #Rosetta #Shirt #sewing — Elly PriZeMaN (@ellypriZeMaN) November 13, 2014 Here’s Glenn Reynolds’s take: So how are things going for…
How very sad that someone with this level of visibility is making the choices Matt Taylor has been making. A female scientist who chose to appear at a public event dressed like the sexualized women on Taylor’s T-shirt would likely be criticized as unprofessional, so it’s only fair to wonder what Dr. Taylor was thinking when he chose to wear…
The theories of evolution and the Big Bang are real and God is not “a magician with a magic wand”, Pope Francis has declared. Speaking at the Pontifical Academy of Sciences, the Pope made comments which experts said put an end to the “pseudo theories” of creationism and intelligent design that some argue were encouraged…
So, who else is taking advantage of current events and assigning “The Masque of the Red Death”? Are we thoughtful educators? Shameless opportunists? Both? (The disease Poe describes is more sudden than that caused by the ebola virus.) No pestilence had ever been so fatal, or so hideous. Blood was its Avatar and its seal—the…
On the other end of the link, the New Yorker has illustrated the blog post with a screen shot from Fox News, but the text of the post actually blames CNN (which recently hyped ebola as the ISIS of bio-agents). An Ohio man has become infected with misinformation about the Ebola virus through casual contact…
All this emphasis on standardized testing in the schools sure makes lots of sense to the purveyors of standardized tests. Stroup testified that for $468 million the Legislature had bought a pile of stress and wasted time from Pearson Education, the biggest player in the standardized-testing industry. Lest anyone miss that Stroup’s message threatened Pearson’s…
Because all of my Seton Hill students get iPads and MacBooks, I try to assign ebooks whenever possible, though students are welcome to use paper, too. This study suggests that students who choose the ebook option have a harder time reconstructing the a timeline of plot events. I’ll keep that in mind as we discuss…
A readable Wired article about why proofreading is difficult. My father, a technical editor for the U.S. Government, says he was so attuned to seeing typos that his brain would show them to him in a larger type size. Typos suck. They are saboteurs, undermining your intent, causing your resume to land in the “pass”…
