The good—the very good—energy news is that the Indian Point nuclear power plants 26 miles north of New York City will be closed in the next few years under an agreement reached between New York State and the plants’ owner, Entergy.

More precisely, space can be viewed as an extremely fine fabric or network "woven" of finite loops.

These networks of loops are called spin networks. The evolution of a spin network over time is called a spin foam. The predicted size of this structure is the Planck length, which is approximately 10−35 meters. According to the theory, there is no meaning to distance at scales smaller than the Planck scale. Therefore, LQG predicts that not just matter, but also space itself has an atomic structure. Today LQG is a vast area of research, developing in several directions, which involves about 50 research groups worldwide.[1] They all share the basic physical assumptions and the mathematical description of quantum space. Research into the physical consequences of the theory is proceeding in several directions.

Challenge Browser. The Tracking and Tracing Books Prize Competition seeks innovations to track books destined for early-grade classrooms and learning centers in low-income countries and allow stakeholders, ranging from parents to Ministries of Education and donor agencies, to quickly and easily access tracking information.

There are three phases to this Prize Competition. Asteroid 2012 DA14 will pass very close to Earth in 2013. A near-Earth asteroid swept safely past Earth on February 15, 2013, and astronomers in many parts of the world were ready with cameras and video equipment. At its closest to us, asteroid 2012 DA14 was within the orbit of the moon (which averages about a quarter million miles away), and closer than some high-orbiting communications satellites. Its closest point was about 17,200 miles (27,680 kilometers) away. World Peace, Global Politics and the Hydrogen Bomb. The Real Nuclear Threat by Dan Eden for In 2009, the following story escaped most news outlets but was widely reported on the Russian and European press:

World Peace, Global Politics and the Hydrogen Bomb

Hidden portals in Earth's magnetic field. A favorite theme of science fiction is "the portal" -- an extraordinary opening in space or time that connects travelers to distant realms.

Hidden portals in Earth's magnetic field

A good portal is a shortcut, a guide, a door into the unknown. If only they actually existed... It turns out that they do, sort of, and a NASA-funded researcher at the University of Iowa has figured out how to find them. "We call them X-points or electron diffusion regions," explains plasma physicist Jack Scudder of the University of Iowa. "They're places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun's atmosphere 93 million miles away.

All-carbon solar cell harnesses infrared light. About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — energy that conventional silicon-based solar cells are unable to harness.

All-carbon solar cell harnesses infrared light

But a new kind of all-carbon solar cell developed by MIT researchers could tap into that unused energy, opening up the possibility of combination solar cells — incorporating both traditional silicon-based cells and the new all-carbon cells — that could make use of almost the entire range of sunlight’s energy. “It’s a fundamentally new kind of photovoltaic cell,” says Michael Strano, the Charles and Hilda Roddey Professor of Chemical Engineering at MIT and senior author of a paper describing the new device that is being published this month in the journal Advanced Materials. A Better Way to Get Hydrogen from Water. An experimental approach to splitting water might lead to a relatively cheap and clean method for large-scale hydrogen production that doesn’t require fossil fuels.

A Better Way to Get Hydrogen from Water

The process splits water into hydrogen and oxygen using heat and catalysts made from inexpensive materials. Heat-driven water splitting is an alternative to electrolysis, which is expensive and requires large amounts of electricity. The new approach, developed by Caltech chemical-engineering professor Mark Davis, avoids the key problems with previous heat-driven methods of water splitting. It works at relatively low temperatures and doesn’t produce any toxic or corrosive intermediate products. Almost all the hydrogen used now in industrial processes, such as making gasoline, comes from reforming natural gas. Your first 3d printer. Custom Printing. EdX - Home.
