| Artificial heart to pump human waste into future robots Posted: 07 Nov 2013 05:42 PM PST A new device capable of pumping human waste into the "engine room" of a self-sustaining robot has been created by a group of researchers.  |
| Posted: 07 Nov 2013 04:18 PM PST Researchers are working to add some accountability to online anonymity. They've developed a technology that offers anonymity for honest users and accountability for dishonest users.  |
| Exploring public perceptions of future wearable computing Posted: 07 Nov 2013 01:21 PM PST As scientists develop the next wave of smartwatches and other wearable computing, they might want to continue focusing their attention on the arms and the wrists. According to a recent study, portable electronic devices placed on the collar, torso, waist or pants may cause awkwardness, embarrassment or strange looks.  |
| Posted: 07 Nov 2013 12:48 PM PST Using inexpensive materials configured and tuned to capture microwave signals, researchers have designed a power-harvesting device with efficiency similar to that of modern solar panels.  |
| The Tao of pee: The science behind urination Posted: 07 Nov 2013 10:26 AM PST Although we don't often think about it, fluid dynamics touches almost every aspect of our lives, from a billowing breeze that buffets a flag, to swirling river currents that shape canyons to the surging blood that sustains our lives. One of the basest of bodily functions -- urination -- is governed primarily by the equations of fluid motion.  |
| Inkblots improve security of online passwords Posted: 07 Nov 2013 09:32 AM PST Computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA (Generating panOptic Turing Tests to Tell Computers and Humans Apart), would be suitable for protecting high-value accounts, such as bank accounts, medical records and other sensitive information.  |
| 'Freakish' asteroid discovered, resembles rotating lawn sprinkler Posted: 07 Nov 2013 09:31 AM PST Astronomers report the discovery of a never-before-seen "weird and freakish object" in the asteroid belt that resembles a rotating lawn sprinkler.  |
| Posted: 07 Nov 2013 07:35 AM PST Cancer patients have the highest probability of recovering if tumors are completely removed. However, tiny clusters of cancer cells are often difficult for surgeons to recognize and remove. A camera makes hidden tumors visible during an operation.  |
| Posted: 07 Nov 2013 06:46 AM PST Astronomers have ruled out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark energy.  |
| More secure app-store for Android Posted: 07 Nov 2013 06:44 AM PST Apps often read the data from mobile user devices unnoticed by users. This represents a large security risk, especially for companies. A new App-Store filters out problematic Android applications automatically with the help of detection software.  |
| Organizing programmed nanoparticles into highly complex nanostructures Posted: 07 Nov 2013 06:40 AM PST A new principle for the self-assembly of patterned nanoparticles may have important implications for nanotechnology and future technologies.  |
| Posted: 07 Nov 2013 06:40 AM PST Nanoparticles, which range from 1-100 nanometers in size, are roughly the same size as biomolecules such as proteins, antibodies, and membrane receptors. Because of this size similarity, nanoparticles can mimic biomolecules and therefore have a huge potential for application in the biomedical field. Scientists have now designed and created multicomponent nanoparticles with specific shapes and structures.  |
| Researchers help make pediatric eye cancer easier to detect Posted: 06 Nov 2013 11:13 AM PST Can parents use digital cameras and smart phones to potentially screen their children for the most common form of pediatric eye cancer? Researchers believe so.  |
