Formation detection could be new tool for visually summarizing a game. An automated analysis by Disney Research Pittsburgh of team formations used during an entire season of professional soccer provides further evidence that visiting teams are less successful than home teams because they play conservatively, not because of a mythical home advantage.
Associated with unhappy visits to the dentist, “cavity” means something else in the branch of physics known as optics .Put simply, an optical cavity is an arrangement of mirrors that allows beams of light to circulate in closed paths. Engineers are developing an optical “nanocavity” to boost light absorption in semiconductors; it could improve solar cells, cameras and more.
All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of neurons. However, Dirk Trauner has helped develop a method which enables all types of neuroreceptors to be controlled by light.
Smart devices - such as tablets and phones - increasingly are an essential part of everyday life on Earth. The same can be said for life off-planet aboard the International Space Station. From astronaut tweets to Google+ Hangouts, our reliance on these mobile and social technologies means equipment and software upgrades are an everyday occurrence - like buying a new pair of shoes to replace a pair of well-worn ones.
Standing in a full-body scanner at an airport isn't fun, and the process adds time and stress to a journey. Researchers now report in ACS' The Journal of Physical Chemistry Letters a more precise and direct method for using that "terahertz" (THz) technology to detect explosives from greater distances. The advance could ultimately lead to detectors that survey a wider area of an airport without the need for full-body scanners.
There is a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion is categorized as a Type Ia supernova....
Starwood Hotels & Resorts wants to replace traditional plastic room keys with smartphone apps. The app would allow guests to skip check-in and go straight to their rooms. The idea of keyless entry is nothing new — see: keyless vehicle entry, industrial security, office ID cards, etc. — but applying it to hotels is certainly novel.
In the last year or two, you may have had some moments — during elections, sporting events, or weather incidents — when you found yourself sending out a flurry of messages on social media sites such as Twitter. You are not alone, of course: Such events generate a huge volume of social-media activity. Now a new study shows that social-media messages grow shorter as the volume of activity rises at these particular times.
In the heart, as in the movies, 3D action beats the 2D experience hands down. The heart is not alone. The human body is replete with examples of soft muscular systems that bend, twist, extend, and flex in complex ways. Engineers have long sought to design robotic systems with the requisite actuation systems that can perform similar tasks, but these have fallen short.
PALO ALTO, California (AP) — Electric car maker Tesla Motors is considering sites in Nevada, Arizona, New Mexico and Texas for a massive battery factory that would employ around 6,500 people. Tesla plans to start construction this year and complete the factory in 2017. The Palo Alto,...
Chinese physicists say quantum key distribution is possible through clear ocean water at distances of up 125 metres and at data rates capable of sending a secure video feed.When it comes to sending information securely, there is one technique that leaves all other in the shade.
The Armatix GmbH .22 iP1 smart gun system works in conjunction with a wristwatch. Both the gun and watch contain RFID chips which communicate with each other and unlock the pistol. Without the watch, the gun won’t operate. In 2002, New Jersey passed a controversial gun-control that required all guns to contain personalization technology....
For the past 24 years, Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford, has been developing a complex computer model to study air pollution, energy, weather and climate. A recent application of the model has been to simulate the development of hurricanes.
The Education Department on Tuesday encouraged school districts to use more scrutiny to protect student privacy when using online educational services. Online companies provide services such as the collection of school lunch money, portals for homework assignments and sites to watch video demonstrations.
Many people use their smartphones to watch video, play games and wake them up in the morning. Some even use them to generate digital boarding passes to fly. So why not use phones to buy stuff at retail stores as well? A variety of mobile wallet systems store credit or debit card information....
