Faces of Our Ancestors. Quantum of Solar: Cells Get Mystery Power Boost. Solar power is becoming more common, but solar cells still aren’t great at harvesting all of the available spectrum of sunlight and turning it into electricity, and they can be expensive.
So researchers are continually looking for ways to improve the efficiency of solar cells and find better ways to make solar cells cheaply. Magnetic Bacteria Could Build ‘Bio-Computers’ Among them are post doctoral research student Pralay Santra and professor Prashant Kamat, of the University of Notre Dame, who are building solar cells with layers of quantum dots, instead of silicon, which is typically used.
Quantum dots are nanometer-sized crystals that glow when stimulated by an external source such as ultraviolet light. They are simpler and cheaper to turn into solar cells than silicon because quantum dots don’t require an expensive chip manufacturing plant. “In typical photovoltaics blue light has more energy (than red light) which gets converted to heat,” Kamat told Discovery News. Complex Body Parts Could Soon Be Lab-Grown. Within a generation, there may be no limit to the kinds of organs and body parts that can be created from scratch.
Various groups of scientists have recently created thyroid cells in the lab, grown a new ear in the skin a woman's own arm, and won a Nobel Prize for figuring out how to reprogram cells so that they can turn into a variety of cell types. In the future, there may be no limit to the kinds of organs and body parts that can be created from scratch. Solar Power Morphs Into Cones and More. All of a sudden everyone seems to be getting funky with the solar cells.
From glass for balconies to spinning cells shaped like ice cream cones, solar power is looking slicker and holding more promise than ever. An LA-based company called V3Solar just made a splash with designs for sapphire blue "Spin Cells" that it says can produce 20 times more electricity than traditional flat, static photovoltaic panels. A cone containing triangular PV cells spins underneath a static shell lens to concentrate the solar power, Ubergizmo's Latif Salman explained.
Navy shows off supersonic railgun, fires test shots. It can blast rounds at 5,600 mph, nail targets located over 100 miles away and may be aboard battleships within the next decade.
It's called the electromagnetic railgun. And last week, naval researchers moved a step closer to delivering a battle-ready weapon as engineers successfully fired a prototype launcher at a test facility. The initial test kicked off a two-month long evaluation of the 32-megajoule test model, which arrived on Jan. 30. Built by military contractor BAE Systems, the prototype looks more like a working naval weapon compared to previous experimental lab-style launchers. General Atomics, another contractor, is also building a second launcher, scheduled for delivery in April.

While NASA scrapes together money to get to Mars, and China slowly ramps up its space program, another spacefaring nation, Russia, has quietly been ferrying astronauts and cosmonauts to the International Space Station.
But now it seems the Kremlin wants to be more than a low-orbit taxi. A leaked document from the Russian space agency Roscosmos outlines the nation's ambitious space exploration strategy until 2030. The plans include replacing the Soyuz rocket with the modular Angara next year; multiple plans to construct Russian space stations after the funding for the ISS ends in 2020; and landing men on the moon with the intent of establishing a lunar base sometime after 2025.

Michael Tipper's Blog — Creating The Time And Space To Live Life To The Full. I was checking my Facebook Notifications this morning and I was drawn to this post made by Nigel Risner on The Global Speakers and Authors Mastermind Group.
I wasn’t sure if the group was open to the public so I copied this because I wanted to share it with you: 12 Signs of a Spiritual Awakening (from an unknown 12-step source) An increased tendency to let things happen rather than make them happen.Frequent attacks of smiling.Feelings of being connected with others and nature.Frequent overwhelming episodes of appreciation.A tendency to think and act spontaneously rather than from fears based on past experience.An unmistakable ability to enjoy each moment.A loss of ability to worry.A loss of interest in conflict.A loss of interest in interpreting the actions of others.A loss of interest in judging others.A loss of interest in judging self.Gaining the ability to love without expecting anything in return …Nice one Nigel .

MIT researchers crack cheap, precise gene therapy. Disease is on the run! An incredible advance in the realm of gene therapy has been made by top researchers in the US and Sweden. A single enzyme from a bacteria’s immune system can effectively be used to locate specific sections of DNA in a living cell. From there, entire genes can be neutralized or replaced with superior sections of DNA. Clearly, we are on the brink of gene therapy becoming a common and highly effective treatment for terrible diseases like AIDS and cancer. A group of researchers from MIT, the Broad Institute, and Rockefeller University have been able to use bacterial protein-RNA systems to find and disrupt the DNA of a virus. Meanwhile, researchers at the Howard Hughes Medical Institute, UC Berkeley, and Emmanuelle Charpentier of the Laboratory for Molecular Infection Medicine have published two papers in Science Express explaining their research on the Cas9 enzyme.
