How does an owl’s tail help it fly? To better see the role of the tail in raptor aerodynamics, researchers at the UK’s Royal Veterinary College recorded birds of prey flying through clouds of tiny helium bubbles. According to the science journal Nature, analyzing the swirling motion of the bubbles enabled the scientists to discover “a new way in which birds use their tail to provide lift and so reduce drag while gliding… Their findings could provide a new way to improve the efficiency of small gliding aircraft.”

The large black bear in this video was observed ambling around a Monrovia, California neighborhood last Friday morning. The bear walked through residential lawns, driveways and rested in a nearby alley.
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
Admit it…even having a pocket knife within reach at a moment’s notice makes you feel a little like James Bond, right? Like, if you run up against a locked vault or a sinister superweapon, all you’d need are a couple of hand-held tools to diffuse the whole situation and save the world. Look, we don’t […]
There’s no shortage of CRMs out there for large corporations, e-commerce companies, and booming startups to utilize. Think Salesforce, for example. But if you’re running a small business of ten employees max, there’s no way it makes sense to invest in an expensive, robust option like that. You’re better off using your old system of […]
Website building apps are all about one thing — helping you craft a great-looking, fast-running website without having to mess with all that back-end code. However, nobody wants their site to look just like a template, so customization is all but a must. So how easy is it to make those changes and still not […]
