| The secret to an effortless, split-second slime attack Posted: 17 Mar 2015 10:46 AM PDT Researchers explain why a tropical worm's twin jets of paralyzing slime are anything but sluggish. The velvet worm is a slow-moving, unassuming creature. With its soft body, probing antennae, and stubby legs, it looks like a slug on stilts as it creeps along damp logs in tropical climates. But it has a secret weapon. In the dark of night, when an unsuspecting cricket or termite crosses its path, the worm unleashes an instantaneous torrent of slime. Two fine jets of the gluey substance spray out of openings on its head, oscillating in all directions to cast a sticky net that entraps prey and stops it in its tracks. |
| Whale fossil, 17 million years old, provides first exact date for East Africa's puzzling uplift Posted: 17 Mar 2015 08:20 AM PDT A 17 million-year-old whale fossil provides the first exact date for East Africa's puzzling tectonic uplift, says paleontologists who rediscovered the fossil. The uplift and aridification associated with the Great Rift Valley of East Africa caused changes in vegetation and have been considered a driver of human evolution. Understanding how, when, and under what conditions the fossil whale was stranded far inland in Kenya now sheds light on the uplift's timing and starting elevation. |
| Posted: 17 Mar 2015 07:41 AM PDT A 3-D printing technology enables objects to rise from a liquid media continuously rather than being built layer by layer as they have been for the past 25 years, representing a fundamentally new approach to 3-D printing. The technology allows ready-to-use products to be made 25 to 100 times faster than other methods and creates previously unachievable geometries that open opportunities for innovation not only in health care and medicine, but also in other major industries such as automotive and aviation. |
| Nanospheres cooled with light to explore the limits of quantum physics Posted: 17 Mar 2015 07:41 AM PDT Scientists have developed a new technology which could one day create quantum phenomena in objects far larger than any achieved so far. The team successfully suspended glass particles 400 nanometers across in a vacuum using an electric field, then used lasers to cool them to within a few degrees of absolute zero. These are the key prerequisites for making an object behave according to quantum principles. |
| Chimpanzees will travel for preferred foods, innovate solutions Posted: 17 Mar 2015 06:31 AM PDT Just as humans will travel to their favorite restaurant, chimpanzees will travel a farther distance for preferred food sources in non-wild habitats, according to a new study. |
