Trying on clothes when a shop is closed could become a reality thanks to new research that uses semi-transparent mirrors in interactive systems. The innovation, which builds on a mirror’s ability to map a reflection to one unique point behind the mirror, independently of the observer’s location, could change the way people interact and collaborate in public spaces, such as museums and shop windows.
A team of Georgia Institute of Technology researchers has created speech-to-text software for Google Glass that helps hard-of-hearing users with everyday conversations. A hard-of-hearing person wears Glass while a second person speaks directly into a smartphone. The speech is converted to text, sent to Glass and displayed on its heads-up display.
The world’s fiber-optic network spans more than 550,000 miles of undersea cable that transmits Email, Websites and other packets of data between continents, all at the speed of light. A rip or tangle in any part of this network can significantly slow telecommunications around the world. Now, engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface.
A rip or tangle in any part of world’s 550,000-mile fiber-optic network can significantly slow telecommunications around the world. Now engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics technology used to animate hair in movies, and theoretical analyses.
Washington State University undergraduate Kellie Wall, 21, recently looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock observations made by the rover Curiosity on Mars’ Gale Crater, inventing a new method for detecting water on Mars.
A new Georgia Institute of Technology study shows that an intense workout of as little as 20 min can enhance episodic memory, also known as long-term memory for previous events, by about 10% in healthy young adults. The research isn’t the first to find that exercise can improve memory. But the study took a few new approaches, including testing memory after just single period of exercise.
Brine shrimp, which are sold as pets known as sea-monkeys, are tiny—only about half an inch long each. With about 10 small leaf-like fins that flap about, they look as if they could hardly make waves. But get billions of similarly tiny organisms together and they can move oceans.
Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, can’t be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after swallowed.
Michael Grätzel’s laboratory in Switzerland is producing hydrogen fuel from sunlight and water. By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3% conversion efficiency from solar energy to hydrogen, a record using earth-abundant materials as opposed to rare metals.
The atmospheric conditions associated with the unprecedented drought currently afflicting California are "very likely" linked to human-caused climate change, according to Stanford Univ. scientists. The team used a combination of computer simulations and statistical techniques to show that a persistent region of high atmospheric pressure hovering over the Pacific Ocean was likely to form from modern greenhouse gas concentrations.
Droplets are simple spheres of fluid, not normally considered capable of doing anything on their own. But now researchers have made droplets of alcohol move through water, even moving through complex mazes. The droplets can be led to certain targets, using a surprisingly simple impetus. In the future, such moving droplets may deliver medicines, moving entire chemistries to targets.
Researchers in the Netherlands have managed to open nanovesicles in a reversible process and close them using a magnet. Previously, these vesicles had been “loaded” with a drug and opened elsewhere using a chemical process, such as osmosis. The magnetic method, which is repeatable, is the first to demonstrate the viability of another method.
A Rice Univ. team led by bioengineer Jeffrey Jacot and chemical engineer and chemist Matteo Pasquali have created new pediatric heart-defect patches infused with conductive single-walled carbon nanotubes that allow electrical signals to pass unhindered. The nanotubes overcome a limitation of current patches in which pore walls hinder the transfer of electrical signals between cardiomyocytes, the heart muscle’s beating cells.
For the first time, scientists led by John V. Badding, a professor of chemistry at Penn State Univ., have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond's structure.
Glenn Johnson, CEO of BlueVine Graphene Industries Inc., said many of the methodologies being utilized to produce graphene today are not easily scalable and require numerous post-processing steps to use it in functional applications. He said his company has developed a way to scale graphene production using a roll-to-roll chemical vapor deposition process.
