| Small satellites soar in high-altitude demonstration Posted: 18 Jun 2013 02:26 PM PDT Four tiny spacecraft soared over the California desert June 15 in a high-altitude demonstration flight that tested the sensor and equipment designs created by NASA engineers and student launch teams.  |
| Finding all asteroid threats to human populations: NASA announces asteroid grand challenge Posted: 18 Jun 2013 02:20 PM PDT NASA has announced a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them. The challenge is a large-scale effort that will use multi-disciplinary collaborations and a variety of partnerships with other government agencies, international partners, industry, academia, and citizen scientists. It complements NASA's recently announced mission to redirect an asteroid and send humans to study it.  |
| Cassini probe to take photo of Earth from deep space Posted: 18 Jun 2013 01:19 PM PDT NASA's Cassini spacecraft, now exploring Saturn, will take a picture of our home planet from a distance of hundreds of millions of miles on July 19. NASA is inviting the public to help acknowledge the historic interplanetary portrait as it is being taken.  |
| Posted: 18 Jun 2013 11:14 AM PDT Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.  |
| Working backward: Computer-aided design of zeolite templates Posted: 18 Jun 2013 07:20 AM PDT Taking a page from computer-aided drug designers, researchers have developed a computational method that chemists can use to tailor the properties of zeolites, one of the world's most-used industrial minerals. The method allows chemists to work backward by first considering the type of zeolite they wish to make and then creating the organic template needed to produce it.  |
| Which qubit my dear? New method to distinguish between neighboring quantum bits Posted: 18 Jun 2013 07:17 AM PDT Researchers have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer. In a significant feat of atomic engineering, they were also able to read-out the spins of individual electrons on a cluster of phosphorus atoms that had been placed precisely in silicon.  |
| A microphone that listens with light: microphones have hyper-acute hearing and a sense of direction Posted: 18 Jun 2013 07:16 AM PDT A new sensor will help to make microphones hypersensitive: "Think of traditional videoconference equipment. Several people are sitting around the table, but the microphone has been placed where its sound reception is less than optimal. With technology of this sort, a microphone will be able to "see" where the sound comes from, pick up the voice of the person speaking, and filter out other sources of noise in the room," explains one of the researchers.  |
| Chemical nanoengineering: Designing drugs controlled by light Posted: 18 Jun 2013 07:15 AM PDT A new breakthrough will help with the development of light-regulated therapeutic molecules.  |
