Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the Univ. of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting.
By combining observations from the Japan-led Suzaku x-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across. The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of its host galaxy.
Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material and it has certain technical advantages over silicon.
In an experiment at the SLAC National Accelerator Laboratory, scientists precisely measured the temperature and structure of aluminum as it transitions into a superhot, highly compressed concoction known as “warm dense matter.” Warm dense matter is the stuff believed to be at the cores of giant gas planets in our solar system and some of the newly observed “exoplanets” that orbit distant suns.
In the on-going search for a better understanding of how the brain and central nervous system develop, a potentially powerful new tool could soon be available. Researchers at Lawrence Berkeley National Laboratory have discovered a light-sensitive opsin protein that plays a surprising and possibly critical role in neuron maturation and circuit formation.
Researchers at the OIST have demonstrated a more robust method for controlling single, micron-sized particles with light. Passing light along optical microfibers or nanofibers to manipulate particles has gained popularity in the past decade and has an array of promising applications in physics and biology. Most research has focused on using this technique with the basic profile of light.
A smart and simple method developed at Rice Univ. to image a patient’s eye could help monitor eye health and spot signs of macular degeneration and diabetic retinopathy, especially in developing nations. The patient-operated, portable device invented at Rice is called mobileVision. It can be paired with a smartphone to give clinicians finely detailed images of the macula, without artificially dilating the pupil.
Engineers at the Univ. of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes, and while recovery is still possible.
An atomically thin membrane with microscopically small holes may prove to be the basis for future hydrogen fuel cells, water filtering and desalination membranes, according to a group of 15 theorists and experimentalists. The team tested the possibility of using graphene as a separation membrane in water and found that naturally occurring defects allowed hydrogen protons to cross the barrier at unprecedented speeds.
A 3D printing technology developed by Silicon Valley startup, Carbon3D Inc., enables objects to rise from a liquid media continuously rather than being built layer-by-layer as they have been for the past 25 years, representing a fundamentally new approach to 3D printing. The technology allows ready-to-use products to be made 25 to 100 times faster than other methods.
Mother-of-pearl, the iridescent layer in the shells of some mollusks, inspired a Rice Univ. study that will help scientists and engineers judge the ultimate strength, stiffness and toughness of composite materials for anything from nanoscale electronics to buildings.
A sophisticated necklace developed by researchers at the Univ. of California, Los Angeles, can monitor food and drink intake, which could help wearers track and improve their dietary habits. The inventors of the WearSens device say it could help battle obesity, heart disease, diabetes and other problems related to nutrition.
Researchers at Massachusetts Institute of Technology have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles: a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
A puzzling observation, pursued through hundreds of experiments, has led Stanford Univ. researchers to a simple yet profound discovery: Under certain circumstances, droplets of fluid will move like performers in a dance choreographed by molecular physics.
Researchers wanted to find a better way to make coatings that can be painted onto surfaces to conduct electricity or convert electricity into hydrogen fuels. Instead, they found a new way to make state-of-the-art materials for energy storage using a cheap lamp from the hardware store.
