| Printable functional 'bionic' ear melds electronics and biology Posted: 01 May 2013 04:32 PM PDT Scientists used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability. The researchers' primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The scientists used 3-D printing of cells and nanoparticles followed by cell culture to combine a small coil antenna with cartilage, creating what they term a bionic ear. |
| Startling survival story at historic Jamestown: Physical evidence of survival cannibalism Posted: 01 May 2013 04:18 PM PDT A forensic analysis of 17th-century human remains proves that survival cannibalism took place in historic Jamestown, Virginia. The findings answer a long-standing question among historians about the occurrence of cannibalism at Jamestown during the deadly winter of 1609-1610 known as the "starving time" -- a period during which about 80 percent of the colonists died. |
| Seahorse's armor gives engineers insight into robotics designs Posted: 01 May 2013 10:21 AM PDT The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers have found. The tail's flexibility is due to its structure, made up of bony, armored plates, which slide past each other. Researchers are hoping to use a similar structure to create a flexible robotic arm, which could be used in medical devices, underwater exploration and unmanned bomb detection and detonation. |
| Bug's view inspires new digital camera's unique imaging capabilities Posted: 01 May 2013 10:19 AM PDT An insect-inspired device uses hemispherical, compound optics to capture wide, undistorted fields of view. |
| Wide-eyed fear expressions may help us -- and others -- to locate threats Posted: 01 May 2013 10:16 AM PDT Wide-eyed expressions that typically signal fear seem to enlarge our visual field making it easier to spot threats at the same time they enhance the ability of others to locate the source of danger, according to new research. |
| The day NASA's Fermi dodged a 1.5-ton bullet Posted: 01 May 2013 07:12 AM PDT NASA scientists don't often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA's Fermi Gamma-ray Space Telescope, checked her email on March 29, 2012, she found herself facing this precise situation. |
| Posted: 01 May 2013 06:19 AM PDT Only within the past 12 years have marine biologists come to learn about the eye-opening characteristics of mystifying sea worms that live and thrive on the skeletons of whale carcasses. Now, scientists at describe how Osedax, mouthless and gutless "bone worms," excrete a bone-melting acid to gain entry to the nutrients within whale bones. |
| Researchers look to mathematics, nature, to understand the immune system and its role in cancer Posted: 01 May 2013 06:18 AM PDT Can patterns in tree branches or the meandering bends in a river provide clues that could lead to better cancer therapies? According to a new study, these self-similar, repeating patterns in nature known as fractals help scientists better understand how the immune system is organized and may one day be used to help improve stem cell transplant outcomes in leukemia patients by predicting the probability of transplant complications. |
| Talking tissue boxes and other smart objects may be welcomed by most people Posted: 01 May 2013 06:18 AM PDT Just as people have embraced computers and smart phones, they may also give their blessing to talking tissue boxes and other smart objects, according to researchers. |
| Possible alternative to bariatric weight loss surgery Posted: 30 Apr 2013 10:15 AM PDT An experimental procedure successfully tested in obese laboratory rats may provide a less-invasive alternative to bariatric weight-loss surgery. Scientists used a catheter to redirect the flow of bile from the bile duct into the small intestine, producing the same metabolic and weight-loss benefits as bariatric surgeries such as gastric by-pass. |
| Happiness: There’s an app for that; Boston bombings unhappiest day in five years, new sensor shows Posted: 30 Apr 2013 10:11 AM PDT The day of the Boston Marathon was the saddest day in nearly 5 years of observations by a team of scientists from the University of Vermont and The MITRE Corporation. For the first time, results from their "hedonometer" are being made available to the public for free at a new website. |
| Revolutionary shape-changing phone curls when called Posted: 29 Apr 2013 10:36 AM PDT Researchers at Queen's University's Human Media Lab have developed a new smartphone -- called MorePhone -- which can morph its shape to give users a silent yet visual cue of an incoming phone call, text message or email. |
