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 majestic image below of the Eagle Nebula’s “Pillars of Creation,” captured by the Hubble Space Telescope in 1995, has become an iconic astronomical photograph. It depicts the visible light, meaning the part of the electromagnetic spectrum that the human eye can see. In this new take above, NASA scientists present the same view of […]
Years ago, I read a bit of advice in The Whole Earth Catalog, which said a great way to get up to speed on a subject you are interested in is to read a children’s book about it. It’s excellent advice, and I’ve made use of it many times over the years. The best children’s […]
Translating abstract scientific data into sound can give researchers new insight into the complexities of the phenomena they are studying. MIT materials science professor and musician Markus Buehler, who has employed this technique to understand biological materials and develop new proteins, has now transformed the novel coronavirus into music. For the recording above, Buehler selected […]
If your sleep has been somewhat troubled recently, you’ve got plenty of company. With so much uncertainty, millions of people everywhere are laying in their beds, wrestling with huge life problems while unsuccessfully trying to also get eight hours of rest…or six…or heck, even 30 minutes. If that hits a little close to home, you […]

If you’ve ever tried to shoot your own videos, you know the equipment costs to do it right can mount up quickly. Even if you’re fine with capturing video on your trusty smartphone, you still need a mount to keep your phone in place. And you’ll need a mic to augment your smartphone’s not so […]
