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.
Yamaha is looking to showcase at the upcoming Tokyo Motor Show not one, but five electric, two-wheeled rides all described as reference vehicle/prototypes. Four of them are best classified as full electric scooters or motorcycles, while the last one is an electrically power assisted bicycle.
One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years.
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins.
Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.
Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than previously believed.
Hopes are high for Comet ISON, which has the potential to become the most spectacular comet seen in years. ISON is speeding through the inner solar system at about 120,000 miles per hour, on its way to a close approach to the Sun on November 28th. Assuming it survives its close encounter, it could become easily visible to the unaided eye in dawn skies.
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.
Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the more energetic photons in the visible part of the spectrum.
Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing.
Researchers from North Carolina State University have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver – moving engineers closer to their goal of creating highway “stations” that can recharge electric vehicles wirelessly as the vehicles drive by.
Evolution does not operate with a goal in mind; it does not have foresight. But organisms that have a greater capacity to evolve may fare better in rapidly changing environments. This raises the question: does evolution favor characteristics that increase a species' ability to evolve?
Somewhere on Earth, there's always a lightning flash. The globe experiences lightning some 50 times a second, yet the details of what initiates this common occurrence and what effects it has on the atmosphere – lightning may be linked to incredibly powerful and energetic bursts called terrestrial gamma ray flashes, or TGFs -- remains a mystery.
Jupiter's Great Red Spot is one of the solar system's most mysterious landmarks. Based on what scientists understand about fluid dynamics, this massive storm – which is big enough to engulf the Earth two or three times over – should have disappeared centuries ago.
Is Google an Internet company or a renewable energy developer? Sometimes it’s hard to tell. The company on Thursday was at it again, announcing that it was joining with the investment firm KKR to buy into six solar photovoltaic power plants being built by Recurrent Energy in California and Arizona. The plants total 106 megawatts of generating capacity.
From the world of crowdfunding meets solar powered gadgets we earlier this week covered the rather extravagant ZingBox retro solar boom box. We now turn to something a little smaller and more practical in scope – a solar charging wristband that doubles as a night light.
If you think with the release of every new i-device the world is getting closer to thought-controlled smart tech and robotic personal assistants, you might be right. And thanks in part to work led by the University of Cincinnati's Anca Ralescu, we may be even closer than you realize.
A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers.
