| A roll of the dice: Quantum mechanics researchers show that nature is unpredictable Posted: 09 Jul 2012 01:27 PM PDT Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather. But in quantum mechanics, even if all the information is available, the outcomes of certain experiments generally can't be predicted perfectly beforehand. power. The paper looks at measurements on members of maximally entangled pairs of photons that are sent into Stern-Gerlach-type apparatus, in which each photon can take one out of two possible paths.  |
| New insights into how the most iconic reaction in organic chemistry really works Posted: 09 Jul 2012 12:54 PM PDT The Diels-Alder reaction is the most iconic organic chemistry reaction. Scientists now report on exactly how this chemical reaction, discovered in 1928, occurs.  |
| Smart headlight system: Shining light between drops makes thunderstorm seem like a drizzle Posted: 09 Jul 2012 12:06 PM PDT Drivers can struggle to see when driving at night in a rainstorm or snowstorm, but a new smart headlight system can improve visibility by constantly redirecting light to shine between particles of precipitation. The system, demonstrated in laboratory tests, prevents the glare that occurs when headlight beams are reflected by precipitation back toward the driver.  |
| Posted: 09 Jul 2012 12:06 PM PDT Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us -- this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Because the devices can be made approximately 75 percent transparent, they could potentially be used in touch screens to replace existing sensors. "Transparent generators can be fabricated on virtually any surface," said one of the researchers. "This technique could be used to create very sensitive transparent sensors that would not require power from a device's battery."  |
| Tiny bubbles snap carbon nanotubes like twigs Posted: 09 Jul 2012 10:35 AM PDT A computer model shows that long nanotubes bend and snap like a twig when blasted with ultrasonic energy. The research finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.  |
| Belching black hole proves a biggie: First known 'middleweight' black hole Posted: 09 Jul 2012 07:27 AM PDT Astronomers have found the first known "middleweight" black hole. Before it was found, astronomers had good evidence for only supermassive black holes -- ones a million to a billion times the mass of the Sun -- and "stellar mass" ones, three to thirty times the mass of the Sun.  |
| 'Fingerprinting' nanoscale objects and viruses Posted: 09 Jul 2012 06:30 AM PDT Scientists have found a way of effectively identifying nanoscale objects and viruses that could offer a breakthrough for biomedical diagnostics, environmental protection and nano-electronics.  |
| Posted: 09 Jul 2012 06:30 AM PDT Batman returns to cinemas for the Dark Knight Rises next month (July 20) - but unless he has invested in a new cape, he may fall into some trouble.  |
