Researchers have developed a suite of technologies that can be used to enhance communication between dogs and humans. It has applications in everything from search and rescue to service dogs to training our pets. The platform opens the door to new avenues for interpreting dogs’ behavioral signals and sending them clear and unambiguous cues in return.
Although naturally occurring vibrations have proven extremely useful to seismologists, the...
In a darkened, hangar-like space a small, Roomba-like robot is trying to make up its mind. A new...
Google's latest "moonshot" project involves detecting cancer by swallowing a pill. The pill is packed with tiny magnetic particles, which can travel through a patient's bloodstream, search for malignant cells and report their findings to a sensor device that you wear.
Stream video on your smartphone, or use its GPS for an hour or two, and you’ll probably see the battery drain significantly. As data rates climb and smartphones adopt more power-hungry features, battery life has become a concern. But, a new chip can essentially “switch gears” to adjust voltage supply to power amplifiers in smartphones as needed, cutting power loss to improve battery life.
If the majority of light-duty vehicles in the U.S. ran on higher-octane gasoline, the automotive industry as a whole would reduce its CO2 emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis. The researchers reasoned that the use of higher-octane fuel could spur manufacturers to design vehicles to run on higher-octane— which could lead to more efficient vehicles.
A proposed change could contribute to a more advanced and reliable electric grid and help lower utility bills. The switch would consist of a plasma-filled tube that turns current on and off in systems that convert the direct current coming from long-distance power lines to the alternating current.
Using ultrasound technology to visualize the tongue’s shape and movement can help children with difficulty pronouncing “r” sounds, according to a small study. The ultrasound intervention was effective when individuals were allowed to make different shapes with their tongue in order to produce the “r” sound, rather than being instructed to make a specific shape.
Highly trained technical divers with a Florida-based group are helping Italian researchers to unlock an ancient shipwreck thought to date to the second Punic Wars between Rome and Carthage. Able to descend hundreds of feet further than most divers, they aide the archaeologists by swimming about the wreck fetching artifacts— as no robotic submersible can.
Scientists combined high-resolution 3-D confocal microscopy and computer-automated analysis of the images to survey the fission yeast genome with respect to three key cellular processes simultaneously: cell shape, microtubule organization and cell cycle progression.
Ferroelectric materials– commonly used in transit cards, gas grill igniters, video game memory and more– could become strong candidates for use in next-generation computers. Researchers have found an easy way to improve the performance of ferroelectric materials in a way that makes them viable for low-power computing and electronics.
Researchers are reporting the transmission of a record high 255 Terabits/sec over a new type of fiber, allowing 21 times more bandwidth than currently available in communication networks. This new type of fiber could be an answer to mitigating the impending optical transmission capacity crunch caused by the increasing bandwidth demand.
Conventional solid-fuel rocket motors work by combining a fuel and an oxidizer to enhance the burning of the fuel. In higher-energy fuels, this mixture can be somewhat unstable, and can contain sensitive high explosives that can detonate. A new rocket fuel and motor design adds a higher degree of safety by separating the fuel from the oxidizer, both novel formulations that are, by themselves, unable to detonate.
A Silicon Valley startup has developed technology to let dispatchers know when a police officer's weapon has been fired. The latest product by Yardarm Technologies would notify dispatchers in real time when an officer's gun is taken out of its holster and when it's fired. It can also track where the gun is located and in what direction it was fired.
At first glance, the static, greyscale display created by a group of researchers might not catch the eye of a thoughtful consumer in a market saturated with flashy, colorful electronics. But a closer look at the specs could change that: the ultra-thin LCD screen is capable of holding three-dimensional images without a power source, making it a compact, energy-efficient way to display visual information.
An optical engineer led the development of the Rapid Adaptive Zoom for Assault Rifles (RAZAR) prototype. At the push of a button, RAZAR can toggle between high and low magnifications, enabling soldiers to zoom in without having to remove their eyes from their targets or their hands from their rifles.
So long, Silicon Valley. These days entrepreneurs and engineers are flocking to a place better known for wave surfing than Web surfing. Amid the palm trees and purple sunsets of the Southern California coastline, techies have built "Silicon Beach."
In the three years since a new standard for gas mileage has been in effect, automakers have surpassed it each year, improving new vehicle fuel economy by about a mile per gallon annually.
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Now, scientists say they have developed a new software-based method that finds leaks even when they’re small, which could help prevent serious incidents— and save money for customers and industry.
Fewer cords, smaller antennas and quicker video transmission may be the result of a new type of microwave circuit. The research team behind these new circuits currently holds an attention-grabbing world record.
Information and communications technology has already revolutionized industries from publishing and entertainment to education and health care– and now, it’s transportation’s turn. Two easy examples: commuters can access real-time traffic information via their mobile phones, while adaptive signal lights can sense that a car is waiting at a red light with no cross-traffic present and switch to green to accommodate it.
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. However, these traps, or defects, in ultra-thin nanotubes can compromise their effectiveness.
Researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions, or side effects. They are using high-performance computers to process proteins and drug compounds in an algorithm that produces reliable data outside of a laboratory setting for drug discovery.
DNA has garnered attention for its potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology and more. Now scientists have designed the first large DNA crystals with precisely prescribed depths and complex 3D features, which could create revolutionary devices.
Engineers have built and tested an earthquake-resistant house that stayed staunchly upright even as it shook at three times the intensity of the destructive 1989 Loma Prieta temblor 25 years ago.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics– a breakthrough that will help develop drugs that can effectively tackle infections in the future. It’s hoped this insight will help scientists to develop new antibiotics with a much lower risk of resistance, and to choose the best medicines for specific outbreaks.
Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.
Facebook is launching a tool that lets users notify friends and family that they are safe during or after natural disasters. The tool, called "Safety Check," will be available worldwide to the social network's 1.32 billion users on computers and mobile devices.
