| Could we one day control the path of lightning? Posted: 19 Jun 2015 12:21 PM PDT Lightning path remains unpredictable, but at a smaller scale, discharges between two electrodes can be guided by laser beams. Scientists have discovered a way to guide electric discharges -- and even steer them around obstacles -- through the clever use of lasers.  |
| Alaska researcher investigates multiple endangered fin whale deaths Posted: 19 Jun 2015 07:35 AM PDT At least nine fin whales have been discovered floating dead in waters from Kodiak to Unimak Pass since late May. 'It is an unusual and mysterious event that appears to have happened around Memorial Day weekend,' said a marine mammal specialist. 'We rarely see more than one fin whale carcass every couple of years.'  |
| Posted: 19 Jun 2015 07:35 AM PDT Scientists have revealed that two species of deep-sea sharks, six-gill and prickly sharks, are positively buoyant -- they have to work harder to swim downward than up, and they can glide uphill for minutes at a time without using their tails.  |
| How bats actually fly to find their prey Posted: 19 Jun 2015 05:46 AM PDT New research helps elucidate how bats actually fly to find their prey. Every night a bat puts in 600-700 kilometres of airtime. Flying low, the animals catch insects at speeds of around 40 metres per second. At night the bat uses its hearing to navigate its way to prey. Bats catch insects continuously using echolocation, an advanced navigation system.  |
| Carrying a table together with a co-operative robot Posted: 19 Jun 2015 05:44 AM PDT From a robot's perspective, humans are normally a nuisance: when robots and humans have to work together, it often leads to problems. Researchers want to teach robots how to interact with humans and work together to accomplish tasks. CogIMon stands for "cognitive compliant interaction in motion." This research group is working on humanoid as well as industrial robots.  |
| A diode a few atoms thick shows surprising quantum effect Posted: 19 Jun 2015 05:30 AM PDT A quantum mechanical transport phenomenon demonstrated for the first time in synthetic, atomically-thin layered material at room temperature could lead to novel nanoelectronic circuits and devices.  |
| Lefties are all right with kangaroos Posted: 18 Jun 2015 10:42 AM PDT Kangaroos prefer to use one of their hands over the other for everyday tasks in much the same way that humans do, with one notable difference: generally speaking, kangaroos are lefties. The finding is the first to consider handedness in wild kangaroos, and challenges the notion that 'true' handedness among mammals is a feature unique to primates.  |
| 'Whale tails' can make martime transport more efficient Posted: 17 Jun 2015 06:17 AM PDT Researchers are testing a model "whale's tail" that can be attached to ships to improve fuel efficiency.  |
| High-tech nanofibers could help nutrients in food hit the spot Posted: 16 Jun 2015 09:31 AM PDT New research outlines how the creation of 'nanofibers' could provide new and improved products and delivery systems for supplementary foodstuffs.  |
| Posted: 16 Jun 2015 06:36 AM PDT Researchers have created stretchable, transparent conductors that work because of the structures' 'nano-accordion' design. The conductors could be used in a wide variety of applications, such as flexible electronics, stretchable displays or wearable sensors.  |
