| Study coaxes clays to make human bone Posted: 30 May 2013 12:28 PM PDT Whether damaged by injury, disease or age, your body as an adult can't create new bone, but maybe science can. Researchers are making strides in tissue engineering, designing scaffolds that may lead to ways to regenerate bone. Scientists have developed a novel method that uses nanosized clays to make scaffolds to mineralize bone minerals such as hydroxyapatite.  |
| Sensitive new microphone modeled on fly ear Posted: 30 May 2013 12:28 PM PDT Using the sensitive ears of a parasitic fly for inspiration, a group of researchers has created a new type of microphone that achieves better acoustical performance than what is currently available in hearing aids.  |
| Posted: 30 May 2013 12:28 PM PDT Researchers are trying to make an artificial cicada for underwater communication.  |
| New speaker system for cars creates separate 'audio zones' for front and rear seats Posted: 30 May 2013 12:28 PM PDT A new approach achieves a significant level of isolation between the front and rear listening zones within a car.  |
| Native Ohioans' speaking patterns help scientists decipher famous moon landing quote Posted: 30 May 2013 12:28 PM PDT Speech scientists and psychologists discuss a novel approach to deciphering Armstrong's famous moon landing quote.  |
| Pebbly rocks testify to old streambed on Mars Posted: 30 May 2013 12:05 PM PDT Detailed analysis and review have borne out researchers' initial interpretation of pebble-containing slabs that NASA's Mars rover Curiosity investigated last year: They are part of an ancient streambed. The rocks are the first ever found on Mars that contain streambed gravels. The sizes and shapes of the gravels embedded in these conglomerate rocks -- from the size of sand particles to the size of golf balls -- enabled researchers to calculate the depth and speed of the water that once flowed at this location.  |
| Radiation measured by NASA's Curiosity on voyage to Mars has implications for future human missions Posted: 30 May 2013 11:59 AM PDT Measurements taken by NASA's Mars Science Laboratory mission as it delivered the Curiosity rover to Mars in 2012 are providing NASA the information it needs to design systems to protect human explorers from radiation exposure on deep-space expeditions in the future.  |
| Asteroid has its own moon, NASA radar reveals Posted: 30 May 2013 11:53 AM PDT A sequence of radar images of asteroid 1998 QE2 -- obtained by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif. -- reveals that it is a binary asteroid. In the near-Earth population, about 16 percent of asteroids that are about 655 feet (200 meters) or larger are binary or triple systems.  |
| Asteroids provide sustainable resource, study finds Posted: 30 May 2013 11:48 AM PDT The prospects of a robotic manufacturing base operating off Earth is not as far-fetched as it used to be according to a study published by a team of NASA researchers. Because asteroids are loaded with minerals that are rare on Earth, near-Earth asteroids and the asteroid belt could become the mining centers for remotely operated excavators and processing machinery. In 20 years, an industry barely imagined now could be sending refined materials, rare metals and even free, clean energy to Earth from asteroids and other bodies.  |
| One of the moon's mysteries solved: Origin of mascon basins Posted: 30 May 2013 11:20 AM PDT A mystery of the moon that imperiled astronauts and spacecraft on lunar missions has been solved. Large concentrations of mass lurk on the lunar surface that can change the gravity field and either pull a spacecraft in or push it off course. Scientists have determined the origin of these mass concentrations.  |
| Scientists capture first images of molecules before and after reaction Posted: 30 May 2013 11:20 AM PDT Using atomic force microscopy, chemists for the first time can capture images of molecules before and after they react, which will allow them to better tune reactions to get the products they want. Chemists and physicists joined forces to develop the technique, which could help scientists study and improve catalytic reactions like those used widely in industry to make chemicals or crack oil.  |
| Water-rock reaction may provide enough hydrogen 'food' to sustain life in ocean's crust or on Mars Posted: 30 May 2013 10:25 AM PDT A chemical reaction between iron-containing minerals and water may produce enough hydrogen "food" to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean floor and parts of the continents, according to a new study.  |
| Android antiviral products easily evaded Posted: 30 May 2013 10:25 AM PDT Think your antivirus product is keeping your Android safe? Think again. Ten of the top Android antiviral products are rendered useless by the simplest attacks.  |
| Comet ISON is hurtling toward uncertain destiny with Sun Posted: 30 May 2013 08:13 AM PDT A new series of images from Gemini Observatory shows Comet C/2012 S1 racing toward an uncomfortably close rendezvous with the Sun. In late November the comet could present a stunning sight in the twilight sky and remain easily visible, or even brilliant, into early December of this year.  |
| New gene delivery method: Magnetic nanoparticles Posted: 30 May 2013 08:11 AM PDT Stent angioplasty saves lives, but comes with complications. A new nanoparticle gene delivery method will hopefully overcome limitations of gene therapy vectors and prevent complications associated with stenting. Stents are the platform for magnetically targeted gene delivery, where genes are moved to cells at arterial injury locations without side effects. These nanoparticles protect genes and help them reach their target in active form, a challenge in gene therapy.  |
| Posted: 30 May 2013 08:09 AM PDT Scientists have demonstrated that a live rabbit could wear contact lenses fitted with inorganic light-emitting diode with no side effects. This new class of hybrid transparent and stretchable electrode paves the way for flexible displays, solar cells, and electronics.  |
| Information transmission a good predictor of credit crisis Posted: 30 May 2013 06:48 AM PDT The recent credit crisis was preceded by a sharp increase in the transmission of information in the largest derivatives market. Such transmissions can therefore serve as indicators for the instability of the market. A team of researchers have discovered this unexpected link.  |
| New mathematical model links space-time theories Posted: 30 May 2013 06:46 AM PDT Researchers have taken a significant step in a project to unravel the secrets of the structure of our Universe.  |
| Microwaves make for faster, greener pharma manufacturing Posted: 30 May 2013 06:46 AM PDT Microwave radiation could provide a faster, greener way to manufacture drugs, according to researchers.  |
| Clear photos in dim light: New sensor a thousand times more sensitive than current camera sensors Posted: 30 May 2013 06:46 AM PDT Cameras fitted with a new revolutionary sensor will soon be able to take clear and sharp photos in dim conditions, thanks to a new image sensor.  |
