For all the promise of graphene as a material for next-generation electronics and quantum computing, scientists still don't know enough about this high-performance conductor to effectively control an electric current.
n our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider (LHC) at CERN. Scientists don’t know what these cosmic accelerators are or where they are located, but new results being reported from “IceCube,” the neutrino observatory buried at the South Pole, may show the way. These new results should also erase any doubts as to IceCube’s ability to deliver on its promise.
Researchers at Scripps Institution of Oceanography at UC San Diego have developed a method for greatly enhancing biofuel production in tiny marine algae. As reported in this week’s online edition of the Proceedings of the National Academy of Sciences, Scripps graduate student Emily Trentacoste led the development of a method to genetically engineer a key growth component in biofuel production.
Astronomers using the combined power of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile and NASA’s Hubble and Spitzer space telescopes have discovered a far-flung trio of primitive galaxies nestled inside an enormous blob of primordial gas nearly 13 billion light-years from Earth. It's possible the trio will eventually merge into a single galaxy similar to our own Milky Way.
A comet's journey through the solar system is perilous and violent. A giant ejection of solar material from the sun could rip its tail off. Before it reaches Mars -- at some 230 million miles away from the sun -- the radiation of the sun begins to boil its water, the first step toward breaking the comet apart.
Costa Rica and geothermal power make obvious sense – the country is teeming with geological activity, a fact apparent to anyone who has visited active volcanoes like Arenal or Poás.
We’ve talked at length here before about how Hyundai seemingly has the lead in the race to bring mass production fuel cell vehicles to market. Already effectively doing this in Europe, the South Korean automaker has now dropped a bombshell of an announcement in the United States with plans to make a limited offering available to retail customers starting next spring.
A computer program called the Never Ending Image Learner (NEIL) is running 24 hours a day at Carnegie Mellon University, searching the Web for images, doing its best to understand them on its own and, as it builds a growing visual database, gathering common sense on a massive scale.
Those who study hydrophobic materials — water-shedding surfaces such as those found in nature and created in the laboratory — are familiar with a theoretical limit on the time it takes for a water droplet to bounce away from such a surface. But MIT researchers have now found a way to burst through that perceived barrier, reducing the contact time by at least 40 percent.
The ever-increasing market for portable electronic devices such as laptops, cell phones and MP3 players has resulted in an equally heavy demand for secondary batteries -- more commonly known as rechargeable batteries -- Lithium-ion (Li-ion) being among the most popular.
Science observations by NASA's Mars rover Curiosity have been suspended for a few days while engineers run tests to check possible causes of a voltage change detected on Nov. 17.
Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they have found it, in new results from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope.
Volkswagen, which earlier this year unveiled production ready models of the e-up! and e-Golf electric cars, will be showing off for its North American debut at the Los Angeles International Auto Show the e-Golf. It will go on sale in select states in the fourth quarter of next year for an as yet undisclosed price.
Queen Elizabeth has marked the official opening of more than few buildings in her time, but until last week never one the likes of One Angel Square, new headquarters of the Co-operative Group.
A famous math problem that has vexed mathematicians for decades has met an elegant solution by Cornell University researchers. Graduate student Yash Lodha, working with Justin Moore, professor of mathematics, has described a geometric solution for the von Neumann-Day problem, first described by mathematician John von Neumann in 1929.
Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy’s Oak Ridge National Laboratory supports a new approach to information storage and processing.
Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.
For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites — the remnants of asteroids that have crashed to Earth?
After months of intensive training, the Swarm mission control team are ready for liftoff on Friday. The team will carefully shepherd the trio of magnetic explorers through their critical launch and early orbit phase, ready to react to any problem. The data from this new mission, planned to last four years, will be used to study the mysteries of Earth’s magnetic field, its interactions with the solar wind and relation to global change.
For those who feel the all-electric Nissan Leaf is a car they wouldn’t be caught dead in because it looks too geeky, the automaker seems to have heard you in some round about fashion. Its answer to this was unveiled ahead of the Tokyo Motor Show in the form of the eye bulging BladeGlider concept.
