Until now, computer simulations of habitable climates on Earth-like planets have focused on their atmospheres. Mathematicians and earth sciences experts in the U.K. have recently taken the next step, creating a computer-simulated pattern of ocean circulation on a hypothetical ocean-covered Earth-like planet. They hope to learn how different planetary rotation rates would impact heat transport with the presence of oceans taken into account.
“Big data” has yet to make a mark on conservation efforts to preserve the planet’s biodiversity. But that may soon change with a new model developed by Univ. of California, Berkeley, biologist Brent Mishler and his colleagues in Australia. This effort leverages the growing mass of data to take into account not only the number of species throughout an area, but also the variation among species and their geographic rarity, or endemism.
Nearly all electronics require devices called oscillators that create precise frequencies. For nearly 100 years, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. However, future high-end navigation systems, radar systems and even possibly tomorrow's consumer electronics will require references beyond the performance of quartz.
Researchers at the Univ. of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light). A standard optical microscope acts as a “nanocamera” whereas the pBNAs are the analogous film.
Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single handedly. Now a new wrist-mounted robot can provide a helping hand—or rather, fingers. Researchers at Massachusetts Institute of Technology have developed a robot that enhances the grasping motion of the human hand.
The possibility that the civilian jetliner downed over war-torn eastern Ukraine with nearly 300 people onboard was hit by a missile could have profound consequences for the world's airlines. Airlines might have to be more vigilant about avoiding trouble spots, making flights longer and causing them to burn more costly fuel. They may even be forced to reconsider many international routes.
Microsoft announced the biggest layoffs in its history Thursday, saying it will cut 18,000 jobs or 14 percent of its workforce as it streamlines its Nokia mobile device business to focus on using the Windows Phone operating system. Although the job cuts had been expected, the extent of them was a surprise.
Biological physicists at Rice Univ. have succeeded in analyzing transmembrane protein folding in the same way they study the proteins’ free-floating, globular cousins. They have applied energy landscape theory to proteins that are hard to view because they are inside cell membranes. The method should increase the technique’s value to researchers who study proteins implicated in diseases and possibly in the creation of drugs to treat them.
Big Websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.
A heat-sensing camera designed at Arizona State University has provided data to create the most detailed global map yet made of Martian surface properties. THEMIS, the nine-band visual and infrared camera on NASA’s Mars Odyssey orbiter, was used to create this map, which is now available online. And citizen scientists are invited to help make it even better.
The common pencil squid may hold the key to a new generation of medical technologies that could communicate more directly with the human body. Materials science researchers in California have discovered that reflectin, a protein in the tentacled creature’s skin, can conduct positive electrical charges, or protons, making it a promising material for building biologically inspired devices.
Scientists in Belgium have recently fabricated the world’s first randomly deformable optical waveguide. This innovative optical link remains functional for bending radii down to 7 mm, and can be stretched to more than a third of its length. A link like this can be used to interconnect optical components within a stretchable system, just like stretchable electrical interconnections.
Scientists at Rice Univ. have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. The new imaging method uses a form of Raman spectroscopy in combination with an intricate but mass reproducible optical amplifier. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 atoms.
The doubling of transistors on a microprocessor occurs roughly every two years, and is the outcome of what is called Moore’s Law. In a bid to continue this trend of decreasing transistor size and increasing computation and energy efficiency, chip-maker Intel has partnered with Lawrence Berkeley National Laboratory to design an entirely new kind of photoresist, one that combines the best features of two existing types of resist.
The next big thing in aviation may be really small. With some no bigger than a hummingbird, the hottest things at this week's Farnborough International Airshow are tiny compared with the titans of the sky, such as the Airbus 380 or the Boeing Dreamliner.
A 3-D porous nanostructure would have a balance of strength, toughness and ability to transfer heat that could benefit, nanoelectronics, gas storage and composite materials that perform multiple functions, according to engineers at Rice Univ. The researchers made this prediction by using computer simulations to create a series of 3-D prototypes with boron nitride, a chemical compound made of boron and nitrogen atoms.
NIST has issued for public review and comment a draft report summarizing 65 challenges that cloud computing poses to forensics investigators who uncover, gather, examine and interpret digital evidence to help solve crimes. The report was prepared by the NIST Cloud Computing Forensic Science Working Group, an international body of cloud and digital forensic experts from industry, government and academia.
Researchers at RIKEN in Japan, in collaboration with researchers from Purdue Univ., have recently demonstrated the scalability of quantum dot architectures by trapping and controlling four electrons in a single device. Circuits based on quantum dots are one of the most promising practical routes to harnessing the potential of quantum computing.
Last year, Massachusetts Institute of Technology researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.
A research team in Illinois has built a new type of tunable nanoscale antenna that could facilitate optomechanical systems that actuate mechanical motion through plasmonic field enhancements. The team’s fabrication process shows for the first time an innovative way of fabricating plasmonic nanoantenna structures under a scanning electron microscope, which avoids complications from conventional lithography techniques.
Firms buy specific keywords, including competitors’ brand names, on search engines such as Google or Bing to reach consumers searching for those words. Online advertisements employing such keywords are called search ads. This practice can backfire, however. A new study shows that any large difference in reputation between the two brand names is further magnified in the minds of consumers.
Developmental processes in all living organisms are controlled by genes. At the same time there is a continuous metabolism taking place. Recent research in Austria has analyzed this interaction in flowering plants. For the first time, changes in metabolism were linked to 3-D morphometric data using micro-computed tomography (micro-CT) for the first time.
Scientists in Israel have recently constructed, for the first time, a photonic router that enables routing of single photons by single photons. At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light, or photon, from the right or the left via an optical fiber. The innovation could help overcome difficulties in building quantum computers.
A cheap, portable, microchip-based test for diagnosing type-1 diabetes could speed up diagnosis and enable studies of how the disease develops. Handheld microchips distinguish between the two main forms of diabetes mellitus, which are both characterized by high blood-sugar levels but have different causes. Until now, making the distinction has required a slow, expensive test available only in sophisticated healthcare settings.
According to recent research in the U.K. , use of electronic health records to understand the best available treatment for patients, from a range of possible options, is more efficient and less costly for taxpayers than the existing clinical trial process.
