Length of yellow caution traffic lights could prevent accidents: study
A couple of years ago, Hesham Rakha misjudged a yellow traffic light and entered an intersection just as the light turned red. A police officer handed him a ticket.
Towards computing with water droplets—superhydrophobic droplet logic
Researchers at Aalto University, Finland, have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly ...
New research eclipses existing theories on the Moon formation
The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as "Theia." Over the past decades scientists have simulated this process and ...
Small but powerful: Fermilab develops magnets for the future High Luminosity LHC
Magnet size is crucial to an accelerator as it determines the final circumference and power. This spring, Fermilab unveiled a 10.4 Tesla magnet that is shorter than the 8 Tesla magnets currently installed ...
How to avoid jack-knifing your truck
Jack-knifing is a major cause of devastation in a road traffic accident involving articulated trucks. Researchers in Greece have now designed a device to prevent this often lethal action of such vehicles. Writing in the International Jo ...
Magnetic turbulence trumps collisions to heat solar wind
(Phys.org) -- New research, led by University of Warwick physicist Dr Kareem Osman, has provided significant insight into how the solar wind heats up when it should not. The solar wind rushes outwards from the raging inferno ...
Project aims to remove space debris
(Phys.org) -- Low Earth Orbit is overcluttered with rogue objects and collision shrapnel that are a constant threat to spacecraft.
Armageddon looming? Bruce Willis couldn't save us from asteroid doom (Update)
(Phys.org) -- According to the internet hysteria surrounding the ancient Mayan calendar, an asteroid could be on its way to wipe out the world on December 21, 2012.
Jets at CMS and the determination of their energy scale
Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions. As quarks and gluons have a net colour charge and cannot exist freely due ...
Taking a bird's eye view could cut wildlife collisions with aircraft
Using lights to make aircraft more visible to birds could help reduce the risk of bird strikes, new research by the US Department of Agriculture (USDA) has found. The study, which examined how Canada geese responded to different ...
Some crash-avoidance systems may work better than others
Certain new crash-avoidance systems are effective in preventing car accidents, while others may do more harm than good, researchers say.
Earth's oldest known impact crater found in Greenland
A 100 kilometre-wide crater has been found in Greenland, the result of a massive asteroid or comet impact a billion years before any other known collision on Earth.
Gas cloud will collide with our galaxy's black hole in 2013
Scientists have determined a giant gas cloud is on a collision course with the black hole in the center of our galaxy, and the two will be close enough by mid-2013 to provide a unique opportunity to observe ...
Most quasars live on snacks, not large meals
(Phys.org) -- Black holes in the early universe needed a few snacks rather than one giant meal to fuel their quasars and help them grow, according to observations from NASA's Spitzer and Hubble space telescopes.
