Firefighters moving through smoke-filled buildings could save vital seconds and find it easier to identify objects and obstacles, thanks to revolutionary reins that enable robots to act like guide dogs. The small mobile robot — equipped with tactile sensors — would lead the way, with the firefighter following a meter or so behind holding a rein. The robot would help the firefighter move swiftly in ‘blind’ conditions.
The Soyuz TMA-16M spacecraft is rolled out by train to the launch pad at the Baikonur Cosmodrome...
The World Wildlife Fund’s ninth annual Earth Hour is set to roll across the globe at 8:30 pm...
The small Lego machine inside the White House whirred, and in a moment it was turning the pages of a story book. One page flipped, then another, ever faster as President Barack Obama marveled at its efficiency. The contraption's eventual aim would be to allow paralyzed or arthritic patients to read books despite their disabilities. "How did you figure this out?" Obama, impressed, asked its inventors.
A device resembling a plastic honeycomb yet much smaller than a bee’s stinger can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact. The work introduces a more effective way to transmit data rapidly on electronic circuit boards by using light.
FIRST Championship is an annual three-and-a-half-day robotics competition that is the culmination of several FIRST programs. The high-tech spectator event brings together three separate robotics competitions. The winning teams from those tournaments join the global competition at FIRST Championship, bringing skills, enthusiasm, infectious good will and, of course, hundreds of amazing robots.
Breaking new grounds in the future of remote-controlled drone technology, researchers have developed a living machine whose flight can be wirelessly controlled with minimal human intervention. Mounted on top of a giant flower beetle, a tiny, electronic backpack with a built-in wireless receiver and transmitter converts radio signals received remotely into a variety of actions in the beetle.
A team of Columbia Engineering researchers has invented a technology — full-duplex radio integrated circuits (ICs) — that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times, or at the same time but at different frequencies.
NASA launched four identical spacecraft March 12, 2015, on a billion-dollar mission to study the explosive give-and-take of the Earth and sun's magnetic fields. The unmanned Atlas rocket — and NASA's Magnetospheric Multiscale spacecraft — soared into a clear late-night sky, right on time. Within two hours, all four observatories were flying free.
Ansys has announced that engineers using ANSYS 16.0 in combination with Intel Xeon technology can realize a 300 percent decrease in solution time. The ANSYS and Intel partnership ensures that simulation engineers performing structural analysis can expect seamless high-performance computing (HPC) operations with multi-core Xeon E5 v3 processors and many-core Xeon Phi coprocessors.
A toilet, conveniently situated near the Student Union Bar at the University of the West of England (UWE Bristol), is proving pee can generate electricity. It is hoped the pee-power technology will light cubicles in refugee camps, which are often dark and dangerous places, particularly for women.
In the future, magnetic vortex structures — so-called skyrmions — have the potential to store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, physicists have succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and have developed a unified theoretical description of their behavior.
A NASA spacecraft is about to reach the end of a nearly eight-year journey and make the first rendezvous with a dwarf planet. The Dawn craft will slip into orbit around Ceres, a dwarf planet the size of Texas, on March 6, 2015. Unlike robotic landings or other orbit captures, the arrival won't be a nail-biter. Still, Dawn had to travel some three billion miles to reach the largest object in the asteroid belt between Mars and Jupiter.
We all like to know our watches keep the time well, but researchers are taking precision to an entirely new dimension. The group demonstrated two cryogenically cooled optical lattice clocks that can be synchronized to a tremendous one part in 2.0 x 10-18 — meaning that they would only go out of synch by a second in 16 billion years. This is nearly 1,000 times more precise than the current international standard cesium atomic clock.
Leonard Nimoy, the actor known and loved by generations of Star Trek fans as the pointy-eared, purely logical science officer Mr. Spock, has died. Nimoy died Friday of end-stage chronic obstructive pulmonary disease at his Los Angeles home, with family at his side, said his son, Adam Nimoy. He was 83.
Pull on a piece of plastic at separate ends; it becomes thinner. So does a rubber band. One might assume tha,t when a force is applied along an axis, materials will always stretch and become thinner. Wrong. Thanks to their peculiar internal geometry, auxetic materials grow wider. After confounding scientists for decades, researchers are now developing mathematical models to explain the unusual behavior of these logic-defying materials
ESA is developing a mini-satellite to test out radically new control systems and techniques and to demonstrate drastically improved mission control capabilities that will arise when satellites can fly more powerful on-board computers. Known as Ops-Sat, it is made up of three CubeSat units with deployable solar panels. Although only 30 cm high, it contains an experimental computer 10 times more powerful than any current spacecraft.
We computational chemists are an impatient lot. Despite the fact that we routinely deal with highly complicated chemical processes running on our laboratory’s equally complex HPC clusters, we want answers in minutes or hours, not days, months or even years. In many instances, that’s just not feasible; in fact, there are times when the magnitude of the problem simply exceeds the capabilities of the HPC resources available to us.
In March, when researchers flip the switch to the world’s largest, most powerful particle accelerator, scientists from all over the world will be watching. Physicists expect the refurbished, higher-energy Large Hadron Collider (LHC) will build on the 2012 discovery of the Higgs particle and crack open even more mysteries of the universe
Of course, I’m talking about the Rube Goldberg Machine Contest! This annual international competition challenges teams of students from middle school to college-age to build the most elaborate and hilarious contraption that successfully achieves the task at hand. This year’s contest is already off and running. The 2015 Task: Erase a Chalkboard.
As scientific researchers, we are often surprised by some of the assumptions made about us by those outside our profession. So we put together a list of common myths we and our colleagues have heard anecdotally regarding scientific researchers.
Named after a legendary sea monster, Kraken Mare is believed to be the largest body of liquid on the surface of Saturn's moon Titan. It extends nearly 150,000 square miles across the moon's north-polar region and is made of liquified hydrocarbons. According to a conference presentation given at the 2015 NASA Institute for Advanced Concepts Symposium, NASA hopes to send a submarine to explore the frigid methane sea by 2040.
An estimated 285 million people are visually impaired worldwide. Age-related macular degeneration alone is the leading cause of blindness among older adults in the Western world. Optics specialist Eric Tremblay from EPFL has unveiled a new prototype telescopic contact lens — the first of its kind — giving hope for better, stronger vision. The optics specialist also debuted complementary smart glasses that recognize winks and ignore blinks
Elon Musk has built a US$12 billion company in an endeavour to pave the way to Mars for humanity. He insists that Mars is a “long-term insurance policy” for “the light of consciousness” in the face of climate change, extinction events, and our recklessness with technology. On the other hand, astronaut Chris Hadfield is sceptical: “Humanity is not going extinct,” he told me.
A towering figure in physics who helped shape our understanding of the universe, Nobel laureate Val Logsdon Fitch died peacefully February 5, 2015. He was 91. Known for foundational contributions to the standard model of particle physics, Fitch is remembered for his modesty and his kindness as well as for his experiments and insight into the fundamental nature of matter.
Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.
It's time to study and maybe even test the idea of cooling the Earth by injecting sulfur pollution high in the air to reflect the sun's heat, a first-of-its-kind federal science report said on February 10, 2015. The idea was once considered fringe — to purposely re-engineer the planet's climate as a last ditch effort to battle global warming with an artificial cloud. No longer.
What if the touchscreen of your smartphone or tablet could touch you back? What if touch was as integrated into our ubiquitous technology as sight and sound? Northwestern University and Carnegie Mellon University researchers now report a fascinating discovery that provides insight into how the brain makes sense of data from fingers.
