The Chevrolet Volt electric car may earn a fuel-efficiency rating of 250 miles per gallon, U.S. automaker General Motors Co. said Tuesday. GM has been working with the Environmental Protection Agency for several years on how to rate the mileage of the Volt, which runs on electricity, but includes a gas-powered engine that generates extra electricity for trips longer than 40 miles, CNNMoney.com reported. Essentially, the Volt will drive the first 40 miles on an electric charge alone. After...

Water is familiar to everyone"”it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work at the Department of Energy's SLAC National Accelerator Laboratory and several universities in Sweden and Japan, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.In all,...

Yale University researchers say they've discovered a repulsive light force that can be used to control components on silicon microchips. The scientists said their finding is important because it means future nanodevices might be controlled by light rather than electricity. The same Yale team of scientists previously discovered an attractive force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems. Now they've discovered a...

Since its discovery just a few years ago, graphene has climbed to the top of the heap of new super-materials poised to transform the electronics and nanotechnology landscape. As N.J. Tao, a researcher at the Biodesign Institute of Arizona State University explains, this two-dimensional honeycomb structure of carbon atoms is exceptionally strong and versatile. Its unusual properties make it ideal for applications that are pushing the existing limits of microchips, chemical sensing instruments,...

Leaving a child in a hot car is like leaving a child in a lit oven, a U.S. emergency physician warns. Dr. Nick Jouriles, president of the American College of Emergency Physicians, says children throughout the country die each year as a direct result of being left alone in a hot vehicle. The most important thing to know is that it does not have to be brutally hot outside for it to be brutally hot inside the car, Jouriles said in a statement. A vehicle's window will act like a greenhouse,...

In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. The research focused on rotating magnetic fields, which play an important part in machines like electric motors and generators. The difficulty for technology at the atomic scale is to replicate this property with rotors the size of small molecules. A...

WASHINGTON, May 19 /PRNewswire-USNewswire/ -- The new White House-brokered agreement on increased auto fuel efficiency averaging 35.5 miles per gallon (MPG) for new cars and light trucks sold in 2016 is "historic and a great beginning for recovering America's position in the global auto market," according to 40MPG.org and TheCLEAN.org. 40MPG.org Founder and Civil Society Institute President and Founder Pam Solo said: "We need to continue fostering innovations that can make U.S. cars even...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'
