Berkeley Lab Study Reveals Origins of an Exotic Phase of Matter

Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity, largely spurred by the game-changing prospect of creating a superconductor that works at room temperature, but it has proved to be a tremendous tangle of complex physics.

Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have teased out another important tangle from this giant ball of string, bringing us a significant step closer to understanding how high- temperature superconductors work their magic. Working with a model compound, the team illuminated the origins of the so-called “stripe phase” in which electrons become concentrated in stripes throughout a material, and which appears to be linked to superconductivity.

Wind energy is one of the cleanest forms of renewable energy along with solar. This is the main reason why wind turbines were some of the very first form of clean energy producers adopted not only by governments, but also people to power their homes. They cost relatively less when compared to installing solar panels.

Reasons to consider powering your house with wind turbines

#1 Contribute To Your Community

Keep your head high and feel proud, you are going to contribute to your community. You can’t obviously store all of the energy that will be produced by your system. You will be able to export excess energy produced by your turbines to the local grid and share the electricity with your neighbors. (more…)

Berkeley Lab Releases Most Comprehensive Databook on China’s Energy and Environment

In the five years since the China Energy Group of the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) released its last edition of the China Energy Databook, China has achieved two dubious distinctions: it surpassed the United States in energy consumption and it surpassed the United States in energy-related emissions of carbon dioxide, becoming the world leader on both scores.

With these important shifts in the global energy landscape, the eighth edition of the China Energy Databook is being released this week. The Databook is the most comprehensive publicly available resource known to exist covering China’s energy and environmental statistics. The China Energy Group researchers have amassed an enormous trove of data from firsthand sources and organized much of it into a relational database, making it far more useful for research and analytical purposes.

Enduring two typhoons over a three-week period in August, Woods Hole Oceanographic Institution (WHOI) researchers, working in partnership with the Okinawa Institute of Science and Technology Graduate University (OIST), have successfully deployed an OceanCube Observatory System in waters off Motobu Peninsula, Japan — a biodiversity hotspot that is home to ecologically significant coral reefs. The observatory system enables real-time monitoring of temperature, salinity, and other chemical, biological and physical data critical to understanding the health of and changes in the coral reef ecosystem.

Okinawa is situated at the northernmost end of the border between the Pacific and the Indian Oceans. The coral reefs there support the highest diversity of endemic species, plants and animals in the world. These coral reefs are also economically valuable, generating as much as 3 trillion yen ($30 billion) globally, and 250 billion yen ($2.5 billion) in Japan. (more…)

New Connection between Stacked Solar Cells Can Handle Energy of 70,000 Suns

North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns worth of energy without losing much voltage as “wasted energy” or heat.

Stacked solar cells consist of several solar cells that are stacked on top of one another. Stacked cells are currently the most efficient cells on the market, converting up to 45 percent of the solar energy they absorb into electricity. (more…)

Ancient secrets which save your sex life

Man has two basic requirements – food and the sexual gratification. In order to enjoy a healthy lifestyle it is important to suffice these two requirements or else you can see chaos and disaster seen among the people. Food we all know and have been consuming since we were kids, however, this is not the case with sex. The desire to have sexual gratification comes when kids turn adolescent.

So, when it comes to sex life, there are different ways to enjoy it, however, if you look at the core, nothing really has changed since past centuries. Though the lifestyle has changed a lot and would continue changing, however, sex life seems to remain unchanged. You will find various ancients secrets, which can help you in having a good sex life. So how about checking some of the ancient secrets that can really save your sex life in the following paragraphs: (more…)

China has potential to be leader in global sustainability

China, with its enormous cities and vast countryside, is a potential star in the ongoing global drama of slashing carbon emissions.

In this week’s Nature, a Michigan State University researcher and an international team of sustainability experts propose a script.

China already is a star in unleashing carbon dioxide emissions. In 2011, it accounted for a quarter of the world’s total. The problems – air pollution, squandered energy resources and economic stresses that squelch growth – also come with tremendous opportunity for China to be leader in slashing emissions. Along the way, China’s vast variety of economic and geographic circumstances offers a chance to set examples for its global neighbors. (more…)

Forecast for Titan: Wild Weather Could be Ahead

Saturn’s moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan’s northern hemisphere, waves could ripple across the moon’s hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA’s Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

“If you think being a weather forecaster on Earth is difficult, it can be even more challenging at Titan,” said Scott Edgington, Cassini’s deputy project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We know there are weather processes similar to Earth’s at work on this strange world, but differences arise due to the presence of unfamiliar liquids like methane. We can’t wait for Cassini to tell us whether our forecasts are right as it continues its tour through Titan spring into the start of northern summer.” (more…)
