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.”

Between November 24 and December 1, 2020, NASA’s Curiosity rover captured the above image on the surface of Mars. The image contains nearly 1.8 billion pixels composed of more than 1,000 images. From NASA: The rover’s Mast Camera, or Mastcam, used its telephoto lens to produce the panorama and relied on its medium-angle lens to […]
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 […]
We’ve been hearing about them for years — literally. We even got some leaked video a few weeks ago of this latest iteration. And now, we may finally have the folding smartphone that buyers are ready to truly embrace. Samsung has dropped its brand new foldable Galaxy Z Flip, and outlets, as esteemed as CNN, […]
The secret to project management is that there really is no secret. In fact, with so many popular and well-proven methodologies around for shepherding a company’s biggest initiatives from concept to completion, leaders are better served following some battle-testing paths rather than trying to build one of their own. It’s a lucrative career option for […]
In a little over a month, golf fans will get an answer to the big question they’ve been asking for almost a year: can Tiger do it again? After his improbable return to majors form with a stunning victory at last year’s Masters in Augusta, everybody’s anxious to see what happens this time around in […]
