The London Array: Can offshore wind power Europe?
The largest offshore wind farm in the world to go online by 2012, powering 750,000 homes in the London metro area.
A potential to generate and sell massive amounts of clean electricity to continental Europe.
The stretch of Scottish coastline used for the array dubbed “the Saudi Arabia of renewable power,”
The first stage of the project will build 630 megawatts of capacity (roughly 25 percent of London’s power needs).
Some estimates put U.K. offshore potential at 25 gigawatts. U.K. consumes 45 gigawatts of steady generation.

Nerve-cell transplants help brain-damaged rats fully recover lost ability to learn
Nerve-cell transplants help brain-damaged rats fully recover lost ability to learn, critical confirmation. Brain cell grafts do stimulate release of growth factors for neurons, regenerate or reorganize part of the brain, and restore cognitive function, in a process called neural plasticity. Study focused on the hippocampus, considered to be the seat of learning and memory. Further study is needed, especially to understand the underlying repair mechanism and the apparent starring role of growth factor in brain health.

Mice With No Dad Live Longer | LiveScience Etc.
Mice With No Father Sperm Live Longer. Female mice produced by using genetic material from two mothers but no father live nearly 30 % longer than mice with the normal mix of maternal and paternal genes.
Their findings provide the first evidence that sperm genes may have a detrimental effect on lifespan in mammals.

Spaceflight Now | Breaking News | Martian meteorite surrenders new secrets of possible life
Martian meteorite possibly brought life to Earth?
Compelling new data that chemical and fossil evidence of ancient microbial life on Mars was carried to Earth in a Martian meteorite is being elevated to a higher plane by the same NASA team which made the initial discovery 13 years ago.
Now, 13 years after the Martian meteorite Allen Hills ALH 84001 life story emerged, the science team finally feels vindicated.....
Their data shows the meteorite is no smoking gun but a full of evidence that supports the existence of life on the surface of Mars, or in subsurface water pools, early in the planet's history.

Digital Rat Brain Spontaneously Develops Organized Neuron Patterns
Digital Rat Brain Spontaneously Develops Organized Neuron Patterns. Simulated neurons begun spontaneously coordinating, and organizing themselves into a more complex pattern that resembles a wave.
This is the beginning of the self-organizing neurological patterns that eventually, in more complex mammal brains, become personality.
The researchers running Blue Brain hope that what they're learning about the organization of neurons in the simulated rat brain will allow them to create a digital human brain within 10 years, even though that is many orders of magnitude more complex than a rat brain.

Tiny technologies could produce big energy solutions - CNN.com
Nanotechnology - end of the old world as we know it. Harnessing the energy of body's natural movements to power small devices.
Even finger bending could power small device. Heartbeat to power medical body monitors.
Nanogenerators to harvest energy from any mechanical movement. Self-assembling, batteries from genetically engineered viruses. Flexible solar cell generators in the fabrics. Spray-on batteries.

List of cellphones radiation levels. There are risks of tumors, namely for heavy usage, and for children. Use speakerphone, do not talk overly long.
Of course, phones also save lives, and we still drive cars, even though we know they kill. Guns also kill.

Cellphones Cause Brain Tumors, Says New Report. Great underestimation of brain tumor risks.
- There is a risk of brain tumors from cellphone use;
- Telecom funded studies underestimate the risk of brain tumors, and;
- Children have larger risks than adults for brain tumors.
- Telecom funded studies underestimate the risk of brain tumors, and;
- Children have larger risks than adults for brain tumors.
This report, sent to government leaders and media today, details eleven design flaws of the 13-country, Telecom-funded Interphone study
The Interphone study, begun in 1999, was intended to determine the risks of brain tumors, but its full publication has been held up for years.
Components of this study published to date reveal what the authors call a 'systemic-skew', greatly underestimating brain tumor risk.
The cardinal design flaws include
--categorizing subjects who used portable phones (which emit the same microwave radiation as cellphones,) as 'unexposed';
--exclusion of many types of brain tumors;
--exclusion of people who had died, or were too ill to be interviewed, as a consequence of their brain tumor;
--and exclusion of children and young adults, who are more vulnerable.

Chevy Volt to go the distance with 230 mpg expected in city driving. GM expects the Volt to consume as little as 25 kilowatt hours / 100 miles in city
"Based on the average cost of electricity in the U.S. (approximately 11 cents per kWh), GM says a typical Volt driver would pay about $2.75 to travel 100 miles, or less than 3 cents per mile"
Wednesday, August 12, 2009
G.M. Puts Volt’s Mileage in City as 230 mpg, Nissan says new all-electric Leaf, out late 2010, will do 367 mpg. Thats 1 liter/100 km, and 0.6 l/100 km
Volt costs $2.75 for electricity to drive 100 miles and that a single overnight off peak charge - 40 miles to run - could be 40 cents.

British and Canadian scientists have found a way of reprogramming skin cells taken from adults, effectively winding the clock back on the cells -
- until they were in an embryonic form.
Scientists have found a way to make an almost limitless supply of stem cells that could safely be used in patients while avoiding the ethical dilemma of destroying embryos.
The work has been hailed as a major step forward by scientists.
Stem cells have the potential to be turned into any tissue in the body, an ability that has led researchers to believe they could be used to make "spare parts" to replace diseased and damaged organs
Because the cells can be made from a patient's own skin, they carry the same DNA and so could be used without a risk of being rejected by the immune system.
In 2007, researchers in Japan and America announced they had turned adult skin cells into stem cells by injecting them with a virus carrying four extra genes. Because the virus could accidentally switch on cancer genes, the cells would not be safe enough to use in patients.

Worm Infects Millions of Computers Worldwide.
A new digital plague has hit the Internet, infecting millions of personal and business computers in what seems to be the first step of a multistage attack.
Experts say it is the worst infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world.
The world’s leading computer security experts do not yet know who programmed the infection, or what the next stage will be.
In recent weeks a worm, a malicious software program, has swept through corporate, educational and public computer networks around the world.
Known as Conficker or Downadup, it is spread by a recently discovered Microsoft Windows vulnerability, by guessing network passwords and by hand-carried consumer gadgets like USB keys.
“This is a really well-written worm.” He said security companies were still racing to try to unlock all of its secrets.
Unraveling the program has been particularly challenging because it comes with encryption mechanisms that hide its internal workings from those seeking to disable it.
Most security firms have updated their programs to detect and eradicate the software, and a variety of companies offer specialized software programs for detecting and removing it.
The program uses an elaborate shell-game-style technique to permit someone to command it remotely.
One intriguing clue left by the malware authors is that the first version of the program checked to see if the computer had a Ukrainian keyboard layout. If it found it had such a keyboard, it would not infect the machine
