Researchers at Georgia Institute of Technology studying the burgeoning phenomenon of crowdfunding have learned that the language used in online fundraising hold surprisingly predictive power about the success of such campaigns. While offering donors a gift may improve a campaign’s success, the study found the language project creators used to express the reward made the difference.
For decades, increasing amounts of data have been successfully stored on media with ever-higher densities. Now, an international team has discovered a physical phenomenon that could prove suitable for use in further data aggregation. Researchers found that domain walls, which separate areas in certain crystalline materials, display a polarization, potentially allowing information to be stored in the tiniest of spaces.
A patent mapping system that considers how patents cite one another may help researchers better understand the relationships between technologies and how they may come together to spur disruptive new areas of innovation. The system, which also categorizes patents in a new way, was produced by a team of researchers from three universities and an Atlanta-based producer of data-mining software.
An international research team led by Mount Sinai Heart at Icahn School of Medicine at Mount Sinai, is testing its novel sugar-based tracer contrast agent to be used with positron emission tomography (PET) imaging to help in the hunt for dangerous inflammation and high-risk vulnerable atherosclerotic plaque inside vessel walls that causes acute heart attacks and strokes.
Plasmonic nanostructures are of great current interest as chemical sensors or imaging agents because they can detect the emission of light at a different wavelength than the excitation light. Researchers have struggled with how to interpret this resonant secondary light emission. Recent work that models the emission as Raman scattering from electron-hole pairs, however, has shown a way to predict emission outcome.
A team at the Laboratory for Attosecond Physics in Germany has constructed a detector which provides a detailed picture of the waveforms of femtosecond laser pulses. Knowledge of the exact waveform of these pulses enables scientists to reproducibly generate light flashes that are a thousand times shorter, just attoseconds, and can be used to study ultrafast processes at the molecular and atomic levels.
Researchers in Texas have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging. A single grain of rice could hold about 10 of these tiny windmills, and hundreds of them could be embedded in a sleeve for a cell phone.
Whales, bats and even praying mantises use ultrasound as a sensory guidance system; and now a new study has found that ultrasound can modulate brain activity to heighten sensory perception in humans. Virginia Tech Carilion Research Institute scientists have demonstrated that ultrasound directed to a specific region of the brain can boost performance in sensory discrimination.
Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, Duke Univ. researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.
A new development by researchers at the Univ. of California, Berkeley, could lead to curtains and other materials that move in response to light, no batteries needed. Engineers have created a new light-reactive material made up of carbon nanotubes and plastic polycarbonate.
The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical metatronic devices that can manipulate light in the way electronic circuitry manipulates the flow of electrons. Now, the birthplace of the digital computer, ENIAC, is using this technology in the rebirth of analog computing.
A team headed by Stefan Eisebitt has developed a new x-ray holography method that will enable snapshots of dynamic processes at the highest spatial resolution. The efficiency of the new method is based on x-ray focussing optics that are firmly fixed to the object to be imaged. This produces a blurry image that can be focused computationally using hologram information.
IBM is investing over $1 billion to give its Watson supercomputer its own business division and a new home in the heart of New York City. The Armonk, N.Y.-based computing company said the new business unit will be dedicated to the development and commercialization of the project that first gained fame by defeating a pair of "Jeopardy!" champions, including 74-time winner Jennings, in 2011.
For years engineers the world over have been trying to use inexpensive, carbon-rich molecules and plastics to create organic semiconductors. Two university research teams have worked together to produce the world’s fastest thin-film organic transistors, proving that this experimental technology has the potential to achieve the performance needed for high-resolution television screens and similar electronic devices.
Gadget lovers are slipping on fitness bands that track movement and buckling on smartwatches that let them check phone messages. Some brave souls are even donning Google's geeky-looking Glass eyewear. For the technology industry, this is exciting time, but also a risky one. No one really knows whether the average consumer can be enticed to make gadgets part of their everyday attire.
Researchers in Switzerland are developing electronic components that are thinner and more flexible than before. They can even be wrapped around a single hair without damaging the electronics. This opens up new possibilities for ultra-thin, transparent sensors that are literally easy on the eye.
Images released by NASA on Tuesday show galaxies that are 20 times fainter than those pictured before. They are from a new campaign to have the 23-year-old Hubble Space Telescope gaze much earlier and farther away than it was designed to see. The spacecraft is now looking within 500 million years after the Big Bang.
Scientists are reporting the development of a novel metal ink made of small sheets of copper that can be used to write a functioning, flexible electric circuit on regular printer paper. Their report on the conductive ink, which could pave the way for a wide range of new bendable gadgets, such as electronic books that look and feel more like traditional paperbacks, appears in ACS Applied Materials & Interfaces.
Intel Corp., the world's largest maker of computer processors, says its processors are now free of minerals from mines held by armed groups in the Democratic Republic of the Congo. It's the first major U.S. technology company to make such a claim about its products.
A newly discovered system of two white dwarf stars and a superdense pulsar is packed within a space smaller than the Earth’s orbit around the sun. The finding is scientists’ best opportunity yet to discover a violation of a key concept in Albert Einstein’s theory of General Relativity: the strong equivalence principle, which states that the effect of gravity on a body does not depend on the nature or internal structure of that body.
Supernovas are thought to be a primary source of a galaxy’s dust. Direct evidence of a supernova’s dust-making capabilities, however, has been slim and cannot account for the volume of dust detected in young, distant galaxies. Striking new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope capture, for the first time, the remains of a recent supernova brimming with freshly formed dust.
New research finds that the social benefits of autonomous vehicles will outweigh the likely disadvantages. Decreased crashes, increased mobility, and increases in fuel economy will drive the technology forward, says RAND Corp. researchers, despite privacy concerns and need for updates in insurance regulations.
A 310-foot "crop circle" in a California barley field that mystified locals this week was explained Sunday: it was a publicity stunt by Nvidia Corp., a maker of chips for PCs and smartphones. The company has announced the Tegra K1, a new chip for tablets and smartphones that contains 192 computing "cores," or mini-computers, for graphics applications.
In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power.
