Any textbook will tell you that oxygen is essential for advanced life to evolve. But why did life not explode when oxygen levels rose dramatically 2.1 billion years ago? This is the big question after a Danish/Swedish/French research team, led by University of Southern Denmark, has shown that the oxygen content 2.1 billion years ago was probably the same as when life exploded 500 million years ago.
Most solar cells used in homes and industry are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy.
Volvo seems to want to be on the cutting edge of electric vehicle research, despite the fact it doesn’t have that much in the way of actual green car offerings as of yet. It’s already been involved in a project that puts power lines in roads to consistently charge EVs passing overhead, and now it is tinkering with energy storage built directly into car panels.
No, the idea isn’t to power commercial air travel with photovoltaic solar – that’s being left that to super-lightweight, experimental efforts like Solar Impulse.
Researchers at the University of Washington have identified the desire to resist constant connectivity and to step back from the online world. The authors of a paper to be presented at the Berlin iConference in early 2014 wanted to understand the overserved.
Like undiscovered groves of giant redwoods, centuries-old living corals remain unmapped and unmeasured. Scientists still know relatively little about the world’s biggest corals, where they are and how long they have lived. The secret to unlocking these mysteries may lie with a shoebox-size flying robot.
Using data from NASA's Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their host star.
Almost a year after Hurricane Sandy, parts of New York and New Jersey are still recovering from billions of dollars in flood damage. Tufts University geologist Andrew Kemp sees the possibility of damage from storms smaller than Sandy in the future.
For NASA and its dozens of missions, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth. All those digital records need to be stored, indexed and processed so that spacecraft engineers, scientists and people across the globe can use the data to understand Earth and the universe beyond.
Developed to help scientists learn more about the complex nature of celestial objects in the universe, astronomical surveys have been cataloguing the night sky since the beginning of the 20th century. The intermediate Palomar Transient Factory (iPTF)—led by the California Institute of Technology (Caltech)—started searching the skies for certain types of stars and related phenomena in February.
Honda luxury brand Acura is now in the second year of production of its more entry level ILX sedan, which is based upon the Honda Civic platform. It is also the second year of a hybrid offering for this model, and it has just been released to Acura showrooms for a starting price of $28,900.
Back-up batteries and solar chargers are fine, but if you’re in a real emergency where phone power is a must, both can be cumbersome and time-consuming. A new gadget on Kickstarter clears through the clutter and puts the power back in your hands–literally.
The Kenyan Wildlife Services (KWS) is going all 2013 on poachers' asses by making rhino horn 100% traceable. Now that's what you call disruptive technology that really makes a difference.
Virginia Tech College of Engineering researchers are part of a national study that has cracked how jellyfish move with the lowest cost of transport of any animal. The findings will be used as researchers continue to design bio-inspired jellyfish for the U.S. Navy.
Lithium-ion batteries are in our cellphones, laptops, and digital cameras. Few portable electronic devices exist that do not rely on these energy sources. Currently battery electrodes contain active materials known as intercalation compounds.
The gauzy rings of Saturn and the dark side of the planet glow in newly released infrared images obtained by NASA's Cassini spacecraft.
A new image of the sunward plunging comet ISON suggests that the comet is intact despite some predictions that the fragile icy nucleus might disintegrate as the sun warms it. The comet will pass closest to the sun on Nov. 28.
Scientists have created a heat-resistant thermal emitter that could significantly improve the efficiency of solar cells. The novel component is designed to convert heat from the sun into infrared light, which can than be absorbed by solar cells to make electricity – a technology known as thermophotovoltaics.
Let’s take a brief moment to travel back in the hybrid time machine to 2010. In late March of that year, Mazda announced it was licensing hybrid technology from Toyota to develop its own hybrid offering, which would likely see the light of day in Japan in 2013.
There’s even more turmoil than usual in the U.S. biofuels policy realm, with lawsuits, demands for criminal investigations, leaked documents and threats flying all over the place.
