Researchers have developed a room temperature frequency comb with increased power based on quantum cascade lasers. Since the discovery of optical frequency combs in the 1990s, many applications in metrology, spectroscopy, and frequency synthesis have emerged. Similar to the way a grandfather clock's pendulum ticks off the seconds before signaling the gears to turn its hands, frequency combs count oscillations and convert them into useful electronic signals.
One group of bilingual speakers used emoticons more often when typing in their second language in casual, online communication than they did when typing in their native tongue, a study has found.
A new, automated method for classifying hundreds of kilometres of the deep sea floor in a way that is more cost efficient, quicker and more objective than previously possible has been developed by researchers.
A new mathematical analysis tool has allowed a deeper understanding of the anatomy of the human head thanks to describing the skull as an extended network structured in ten modules. For the first time ever, the researchers added the head muscles and cartilages to the study of the skull bones (including the inner ear bones, the jaw and the bones that connect with head muscles, such as cervical vertebrae and clavicles).
Crowdsourcing -- where responses to a task are aggregated across a large number of individuals recruited online -- can be an effective tool for rating sounds in speech disorders research, according to a study.
A team of researchers is exploring new materials that could yield higher computational speeds and lower power consumption, even in harsh environments.
Scientists have demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these scales – and pave the way for enhanced signal processing on mass-producible silicon photonic chips. In the last decade, the field of silicon photonics has gained increasing attention as a key driver of lab-on-a-chip biosensors and of faster-than-electronics communication between computer chips. The technology builds on tiny structures known as silicon photonic wires, which are roughly a hundred times narrower than a typical human hair. These nanowires carry optical signals from one point to another at the speed of light. They are fabricated with the same technological toolset as electronic circuitry. Fundamentally, the wires work only because light moves slower in the silicon core than in the surrounding air and glass.
We often view hackers as evil geniuses, but perhaps a more accurate depiction would be a talented -- though sometimes mischievous -- craft worker, according to a researcher. The way society views hackers is not representative of the whole hacking culture. Simply stated: Hacking is more than breaking into security systems and computer networks.
Scientists have invented a device, called Google Lens, that could have positive ramifications in the medical field and beyond.
A research team has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.
A major new research database revealing extraordinary data on immigration in England in the late medieval period has been launched by investigators. It reveals evidence about the names, origins, occupations and households of a significant number of foreign nationals who chose to live and work in England in the era of the Hundred Years War, the Black Death and the Wars of the Roses. The project contributes to debates about the longer-term history of immigration to Britain, helping to provide a deep historical and cultural context to contemporary debates over ethnicity, multiculturalism and national identity.
Corannulene is a carbon molecule with a unique shape (similar to the better known fullerene) and promising properties. A team of scientists carried out computer simulations of the molecule’s properties and discovered that it might help overcome the difficulties building molecular circuits (i.e., of the size of molecules).
Along with technological development, traditional teaching methods have been challenged by various technologically enhanced teaching and learning methods. This trend has received mixed reactions: On the one hand it is feared that these new technologies will replace teachers altogether. On the other hand, the expectations towards technology can also be over-optimistic; that it will solve all the problems of learning.
Analysis of massive online data can reveal what information matters to us and with whom we have most in common. For example, networks can be used to study how information travels from one part of the world to another.
On Feb. 12, Facebook rolled out a new feature called Legacy Contact, which gives people a platform for remembering and celebrating the lives of loved ones when they die.
French artist Paul Gauguin is well known for his colorful paintings, but he also was a highly experimental printmaker. Little is known, however, about how he created his complex graphic works. Now a team of scientists and art conservators has used a light bulb, an SLR camera and computational power to uncover new details of Gauguin's process -- how he formed, layered and re-used imagery to make 19 unique graphic works.
Protecting people's privacy in an age of online big data is difficult, but doing so when using visual representations of such things as social network data may present unique challenges, according to a computer scientist.
Researchers are developing a mathematical technique to predict the emergence of scientific innovation, based on research citations and historical analysis.
The the world's first compact 3-D printer that can also scan items into digitized models. will be delivered to the United States in March. This user-friendly device allows users without much knowledge of 3-D software to scan any item, then edit the digitized model on the computer and print it out in 3-D.
In the first experimental use of algorithms that employ structure-based molecular modeling to optimize deimmunized drug candidates, researchers complement their prior sequence-based deimmunizing algorithms and expand the tool kit of protein engineering technologies to use in next generation drug development.
