| Particle physics research sheds new light on possible 'fifth force of nature' Posted: 21 Feb 2013 04:27 PM PST In a breakthrough for the field of particle physics, researchers have established new limits on what scientists call "long-range spin-spin interactions" between atomic particles. These interactions have been proposed by theoretical physicists but have not yet been seen. Their observation would constitute the discovery of a "fifth force of nature" (in addition to the four known fundamental forces: gravity, weak, strong and electromagnetic) and would suggest the existence of new particles, beyond those presently described by the Standard Model of particle physics.  |
| Robotic bat wing engineered: Researchers uncover flight secrets of real bats Posted: 21 Feb 2013 11:39 AM PST Researchers have developed a robotic bat wing that is providing valuable new information about dynamics of flapping flight in real bats. From an engineering perspective, the researchers hope the data may make for better aircraft, especially micro air vehicles. From a biological and evolutionary perspective, building the robot offered the researchers a new perspective on how bat anatomy is adapted to deal with the forces generated by flapping wings.  |
| Floral signs go electric: Bumblebees find and distinguish electric signals from flowers Posted: 21 Feb 2013 11:39 AM PST Flowers' methods of communicating are at least as sophisticated as any devised by an advertising agency, according to a new study. The research shows for the first time that pollinators such as bumblebees are able to find and distinguish electric signals given out by flowers. However, for any advertisement to be successful, it has to reach, and be perceived by, its target audience.  |
| Posted: 21 Feb 2013 11:16 AM PST Black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. In a recent article, researchers predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped by the extreme gravity of the black hole and by powerful magnetic forces generated by its spin.  |
| How to kill an asteroid? Get out a paint spray gun Posted: 21 Feb 2013 11:11 AM PST There is research that is off the wall, some off the charts and some off the planet, such as what a Texas A&M University aerospace and physics professor is exploring. It's a plan to deflect a killer asteroid by using paint, and the science behind it is absolutely rock solid, so to speak, so much so that NASA is getting involved.  |
| Writing without keyboard: Handwriting recognition on the wrist Posted: 21 Feb 2013 06:18 AM PST Typing text messages on the mobile phone via the tiny soft keyboard is very cumbersome. How about simply writing it into the air! This idea drove the development of "airwriting" by computer scientists. Sensors attached to a glove record hand movements, a computer system captures relevant signals and translates them into text.  |
| Common swifts make mysterious twilight ascents Posted: 21 Feb 2013 05:47 AM PST Common swifts climb to altitudes of up to 2.5 km both at dawn and dusk. This unexpected behavior was discovered by a geo-ecologist.  |
| Insects inspiring new technology: Autonomous navigation of mobile robots based on locust vision Posted: 21 Feb 2013 05:46 AM PST The way in which the locust's distinctive visual system could be transferred into technology for state of the art vehicle collision sensors, surveillance technology and video games has been detailed as part of robotics research.  |
| When children can hop on one leg: Motor development in children under 5 can now be tested reliably Posted: 21 Feb 2013 05:46 AM PST Researchers have determined normative data for different exercises such as hopping or running. This enables parents and experts to gauge the motor skills of young children for the first time objectively and thus identify abnormalities at an early stage.  |
| Scrap 'unwinnable' drugs war and divert funds into curbing global antibiotic misuse, experts say Posted: 20 Feb 2013 03:49 PM PST Governments around the world should stop squandering resources fighting an "unwinnable war" against illegal drugs, such as cocaine and heroin. Instead, they should use the cash to curb antibiotic misuse, which poses a far more serious threat to human health, claims a leading ethicist.  |
