Maybe their moms told them nobody likes a showoff. That would explain why many species of chameleon are hiding fluorescent bone bumps on their heads that scientists only just discovered. Chameleons also have independently moving eyeballs, superlative tongues and sophisticated color-changing skills. The animals might use their glowing head bumps as signals to each other. These patterns of dots are invisible to a human eye, but may light up deep blue to the eye of ano ...read more

 Perhaps you've heard that many bird species are monogamous, including swans and whooping cranes. But have you ever wondered how these long term lovers get together? Do they "date", or is it love (and breeding) at first sight? These scientists set out to answer these questions by studying the life history of the whooping crane. They found that "a substantial portion (62%) of breeding pairs started associating at least 12 months before first breeding, with 16 of 58 breeding pa ...read more

On the morning of January 31, people with clear skies across western North America will have front-row seats to the first total eclipse of the Moon since September 2015. For 76 minutes, the full moon will lie completely immersed in the darkest part of Earth’s shadow, and the only light hitting the Moon will be the reddish glow from all of our planet’s sunrises and sunsets. But don’t fret if you live farther east — residents across the eastern half of the continent will st ...read more

The Romantic Period of the early 1800s was marked by a morbid fascination with mortality and death. Poets, novelists and other artists tackled the eternal void head on, rather than whisking such dark topics under the proverbial rug. With death in vogue, even mathematicians took a stab on the beauty of ceasing to be. In 1825, British autodidact Benjamin Gompertz found the risk of death increases exponentially with age. After the age of 30, his depressing model shows, the risk of dying on a ...read more

Strava is a fitness app that allows users to map their jogging routes, and recently it released a heatmap of where people are getting their fat-burn on around the world—secret military bases included. Oops. Strava released the heatmaps in November, and they showed off the fun side of generating data points while you sweat. But then someone came along and ruined all the fun. An Australian student tweeted that the route maps made United States military bases across the world easily iden ...read more

Sick of asking people for a light? Trying to put the spark back into your life? One solution: Buy yourself a flamethrower. If you're looking to burn a hole in your pocket, Elon Musk's Boring Company is selling the fiery devices for just $500 (plus taxes and shipping), and by all indications, they're going fast. Musk has been tweeting order counts by the thousand, and he most recently pegged the number at 7,000. The Tesla and SpaceX founder says he's planning to sell 20,000 total, in what ...read more

People think they want holograms, but they (usually) don’t. These are illusions, images trapped on two-dimensional surfaces that give the impression of a three-dimensional object. What people really want are “volumetric images” — a display of free-floating light that actually takes up 3-D space, visible from all angles. (Bonus points if you can interact with it.) Many of the coolest movies have them, from Tony Stark’s displays in Iron Man, to the projection table i ...read more

These goblins don't work in banks, nor do they lurk in basements. They do, however, creep through the underbrush and conceal themselves in forest canopies in the hopes of waylaying oblivious passers-by. Goblin spiders are tiny, usually on the order of just a few millimeters long, but they can be ferocious hunters. One paper describes them leaping onto the backs of springtails and biting them into submission, despite their unfortunate steed's attempts to throw them off. There are many spec ...read more

"Social priming" has recently been one of the most controversial topics in psychological science. With failures to replicate proliferating, the field has been called a train-wreck. But what exactly is it? Here's how I defined social priming in a 2016 post: “Social priming” has been the punching-bag of psychology for the past few years. The term “social priming” refers to the idea that subtle cues can exert large, unconscious influences on human behaviour. The classi ...read more
