| Posted: 22 Oct 2012 01:27 PM PDT Engineers have found that by listening to how a highway bridge sings in the rain they can determine serious flaws in the structure. Employing a method called impact-echo testing, experts can diagnose the health of a bridge's deck based on the acoustic footprint produced by a little bit of water. Specifically, the sound created when a droplet makes impact can reveal hidden dangers in the bridge.  |
| Can your body sense future events without any external clue? Posted: 22 Oct 2012 11:53 AM PDT Wouldn't it be amazing if our bodies prepared us for future events that could be very important to us, even if there's no clue about what those events will be? "Presentiment," as in "sensing the future," without any external clues may exist, according to new research that analyzes the results of 26 studies published between 1978 and 2010.  |
| Optometrist warns about wearing tinted contact lenses on Halloween Posted: 22 Oct 2012 11:51 AM PDT Decorative tinted contact lenses will be popular accessories this Halloween, but an optometrist is warning that improper use without a prescription could cause severe eye damage.  |
| Beetles use dung balls to stay cool Posted: 22 Oct 2012 09:20 AM PDT Dung beetles roll their feasts of dung away to avoid the hoards of other hungry competitors at the dung pile. But now a team of researchers from South Africa and Sweden have discovered that they also use their balls in another, rather clever way. The moist balls keep the beetles cool even as they push a weight up to 50 times heavier than their own bodies across the hot sand.  |
| A whale with a distinctly human-like voice Posted: 22 Oct 2012 09:20 AM PDT For the first time, researchers have been able to show by acoustic analysis that whales -- or at least one very special white whale -- can imitate the voices of humans. That's a surprise, because whales typically produce sounds in a manner that is wholly different from humans.  |
| Posted: 22 Oct 2012 08:28 AM PDT Researchers have created a model that might explain how water could produce the flow patterns seen by a spacecraft orbiting Mars.  |
| 'Blue' light could help teenagers combat stress Posted: 22 Oct 2012 08:28 AM PDT A new study shows that exposure to morning short-wavelength "blue" light has the potential to help sleep-deprived adolescents prepare for the challenges of the day and deal with stress, more so than dim light.  |
| How fear can skew spatial perception Posted: 22 Oct 2012 05:11 AM PDT That snake heading towards you may be further away than it appears. Fear can skew our perception of approaching objects, causing us to underestimate the distance of a threatening one, a new study finds.  |
| Astronomers study 2-million-light-year 'extragalactic afterburner' Posted: 22 Oct 2012 04:14 AM PDT Blasting over two million lights years from the centre of a distant galaxy is a supersonic jet of material that looks strikingly similar to the afterburner flow of a fighter jet, except in this case the jet engine is a supermassive black hole and the jet material is moving at nearly the speed of light.  |
