| Lonely 'lefty' snail seeks mate for love, and genetic study Posted: 21 Oct 2016 09:04 AM PDT Scientists are hoping to study the genetics of an ultra-rare garden snail are asking the public for its help in finding the lonely mollusc a mate. The snail's unique qualities make it a one in a million find - but also impossible for it to mate with its more common counterparts. At first glance, the brown garden snail may look like any other but closer inspection of the snail's shell reveals exactly why this creature is so special. While the shells of this common species spiral in a right-handed, clockwise direction – known as dextral – this snail is a sinistral, with a left-handed anti-clockwise spiralling shell. In essence, the 'lefty' snail is a mirror image of its other shell-dwelling friends. |
| Windsurfing swans: An overlooked phenomenon Posted: 21 Oct 2016 05:43 AM PDT It is well-known that birds can fly, swim and walk, but now there is scientific evidence that birds also can windsurf. Researchers report that the Mute swan occasionally uses the wings as sails when moving quickly on water surfaces. |
| Exploring vast 'submerged America,' marine scientists discover 500 bubbling methane vents Posted: 20 Oct 2016 07:38 AM PDT Five hundred vents newly discovered off the US West Coast, each bubbling methane from Earth's belly, top a long list of revelations about "submerged America" being celebrated by leading marine explorers. The discoveries double to about 1,000 the number of such vents now known to exist along the continental margins of the USA. This fizzing methane is a powerful greenhouse gas if it escapes into the atmosphere; a clean burning fuel if safely captured. |
| Space-based droplet dynamics lessons? Posted: 18 Oct 2016 08:25 AM PDT Droplets in space can grow freakishly large and bounce off nonwetting surfaces in truly unearthly ways. Astronauts frequently encounter huge droplets, and Scott Kelly recently demonstrated their unusual behavior aboard the International Space Station (ISS) via water balls and a hydrophobic (water repellant) ping pong paddle. |
