Imagine playing a video game and having the ability to lead your virtual army unit while moving freely throughout your house. Gaming could become this realistic, thanks to new technology that allows for highly accurate, 3-D motion tracking. The new system, dubbed “WiTrack”, uses radio signals to track a person through walls and obstructions

The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing. The algorithm allowed computers to quickly perform Fourier transforms — fundamental operations that separate signals into their individual frequencies — leading to developments in audio and video engineering and digital data compression.
In the early hours of November 27, 2013, Comet ISON entered the field of view of the European Space Agency/NASA Solar and Heliospheric Observatory. In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. The comet is seen in the lower right; a giant cloud of solar material, called a coronal mass ejection or CME, is seen billowing out under the sun.
Scientists recently recorded the lowest temperatures on Earth at a desolate and remote ice plateau in East Antarctica, trumping a record set in 1983 and uncovering a new puzzle about the ice-covered continent. Glaciologists found temperatures from -134 to -137 degrees Fahrenheit in a 1,000-kilometer long swath on the highest section of the East Antarctic ice divide.
As a new year approaches, the University of Notre Dame’s John J. Reilly Center for Science, Technology and Values has released its annual list of emerging ethical dilemmas and policy issues in science and technology for 2014.
The European Space Agency is planning to land an unmanned spacecraft on a comet next year in an unprecedented and exquisitely tricky mission that has been underway for almost a decade and is about to enter a critical new phase.
Need a hand lifting something? A robotic device invented by University of Pennsylvania engineering students can help its wearer carry an additional 40 pounds (18 kilograms).
The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP (National Polar-orbiting Partnership) satellite acquired two nighttime images early on October 1, 2013, for this natural-light, mosaic view of the continental United States.
Among the most common tools in electrical engineering and computer science are rectangular grids of numbers known as matrices. The numbers in a matrix can represent data, and they can also represent mathematical equations.
NASA's Curiosity rover has uncovered signs of an ancient freshwater lake on Mars, which scientists say could have been a perfect spot for tiny primitive organisms to flourish if they ever existed on the red planet.
This MODIS image taken by NASA’s Aqua satellite on Nov. 10, 2013, shows an iceberg that was part of the Pine Island Glacier and is now separating from the Antarctica continent.
Sandia National Laboratories researchers have devised a novel way to realize electrical conductivity in metal-organic framework (MOF) materials, a development that could have profound implications for the future of electronics, sensors, energy conversion and energy storage.
Students may soon be able to reach out and touch some of the theoretical concepts they are taught in their physics classes thanks to a novel idea devised by a group of researchers from Imperial College London.
Massive X-ray superbursts near the surface of neutron stars are providing a unique window into the operation of fundamental forces of nature under extreme conditions. The importance of discovering an unknown energy source of titanic magnitude in the outermost layers of accreting neutron star surfaces is heightened by the unresolved issue of neutrino masses, the recent discovery of the Higgs boson ...
The heat shield for NASA's Orion spacecraft was loaded onto a Super Guppy plane in Manchester, NH, on December 4, 2013, for transport to Kennedy Space Center in Florida. The heat shield, the largest of its kind ever built, was unloaded Thursday, December 5, and is scheduled for installation on Orion in March 2014.
University of Iowa researchers may have come up with the right matchmaking formula for online dating sites: Pair people according to their past interests and online mating success, rather than who they say they're interested in.
An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet – a planet outside of our solar system – discovered at the UA. Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b...
After intense preparations and consensus building, CERN has confirmed that the SCOAP3 Open Access publishing initiative will start on January 1, 2014. With the support of partners in 24 countries, a vast fraction of scientific articles in the field of high-energy physics will become Open Access at no cost for any author
This 4x photograph of a wool flower (Celosia)’s flame-like flower head was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. It was taken by Christina Zimmerman of the Merritt College Microscopy Program
China launched its first rover mission to the moon, sending a robotic craft named Jade Rabbit to trundle across the lunar landscape, examine its geology and beam images back to Earth. A rocket carrying the rover aboard an unmanned Chang'e 3 spaceship successfully blasted off early December 2, 2013, from a launch center in southwestern China and was scheduled to arrive on the moon in mid-December, the official Xinhua News Agency said.
Simple imaging devices modified to inexpensive mini-microscopes are the new weapon in fight against tropical infectious diseases, show the researchers at the Institute for Molecular Medicine Finland, FIMM, University of Helsinki and Karolinska Institutet.
Two EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers. Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data. The breakthrough could increase the throughput of data in telecommunications systems by a factor of ten. Optical fibers carry data in the form of pulses of light over...
Love them or hate them, cockroaches are notoriously good escape artists and can flee at astonishing speeds. However, this speed can make it difficult to sense the world around them: 'When animals move slowly they rely mostly on their nervous system for accomplishing tasks, but as the animals are pushed to more extreme performances they face potential constraints in their nervous system, for...
India's Mars orbiter mission left Earth's sphere of influence early December 1, 2013, after performing a maneuver to put it on its way to orbit the red planet. The spacecraft fired its main engine for more than 20 minutes to reach the correct velocity to leave the Earth's orbit, the Bangalore-based Indian Space Research Organization said.
In these parts, a pay phone is a visitor's best option for reaching the rest of the world. A cell phone signal is an hour away by car. Wifi is forbidden. The radio plays nothing but static. And other than the occasional passing pickup truck whose driver offers a wave, it's dead silent.
With the help of NASA's Chandra X-ray Observatory and the Australia Telescope Compact Array, an international team of astronomers has identified the glowing wreck of a star that exploded a mere 2,500 years ago — the blink of an eye in astronomical terms.
