FBI Pushes For Surveillance Backdoors On Internet Companies
CNET learns the FBI is quietly pushing its plan to force surveillance backdoors on social networks, VoIP, and Web e-mail providers, and that the bureau is asking Internet companies not to oppose a law making those backdoors mandatory.
The FBI is asking Internet companies not to oppose a controversial proposal that would require firms, including Microsoft, Facebook, Yahoo, and Google, to build in backdoors for government surveillance.
In meetings with industry representatives, the White House, and U.S. senators, senior FBI officials argue the dramatic shift in communication from the telephone system to the Internet has made it far more difficult for agents to wiretap Americans suspected of illegal activities, CNET has learned.

How Much Water Is On Planet Earth?
If You Collected All Of Earth’s Water Into A Sphere, How Big Would It Be? -- io9
Imagine the Earth in your mind's eye. Now round up all the water on the planet into a sphere (we're talking oceans, icecaps, atmosphere, everything — even the water bound up in you and me). How big do you think that sphere would be compared to the Earth?
Got your answer? Our water sphere would have a diameter of 1,385 kilometers (about 860 miles), and span the distance from Salt Lake City, Utah to Topeka, Kansas. A sphere this far across would have a volume equal to about 1,386 million cubic kilometers (roughly 332,500,000 cubic miles). Those might sound like big numbers (and they certainly are big numbers) but wait until you see this sphere beside the Earth.

My Comment: What a surprise .... that is not a lot of water.

Testing the Long-Awaited Fisker Karma Plug-In Hybrid -- Popular Science
At the 2008 Detroit Auto Show, the start-up Fisker Automotive unveiled its Karma concept , a high-end plug-in hybrid the company would use to challenge Tesla Motors. Cofounder Henrik Fisker said the Karma would go on sale in late 2009. Then the recession, a switch in battery suppliers and other delays kept Fisker from shipping the first trickle of cars until late last year. This spring, we got one of the first test drives.

U.S. Army Wants To Give War Robots More Power To 'Make Their Own Decisions'
Giving war robots 'autonomy' sparks fears of independent killing machines similar to Arnold Schwarzenegger's The Terminator
What Could Possibly Go Wrong? U.S. Army Wants To Give War Robots More Power To 'Make Their Own Decisions' -- Daily Mail
* Trucks that 'drive themselves' already under test
* Military is testing 'autonomous' robots that follow soldiers
* Robots will use laser-imaging to build their own 3D image of the world
* Will be 'supervised' by soldiers
Armies of robots including dog-like creatures walking on four legs and huge lumbering trucks are the stuff of science fiction - specifically, bleak films such as The Terminator series.
But the U.S. military not only wants more robots - it wants more 'autonomous' robots, robots free to make their own decisions on the battlefield.
A new robot is described as 'like a dog' that follows troops on the battlefield - and future models will use technologies such as laser imaging to build their own picture of the world.

Black Holes Are Pretty Much the Sharks of Space
Black Hole Devouring Star NASA, S. Gezari (JHU), and J. Guillochon (UC Santa Cruz)
Omnivorous Black Holes Like This One Are Pretty Much the Sharks of Space - -Popular Science
Scientists from the Harvard-Smithsonian Center for Astrophysics and Johns Hopkins University report seeing a phenomenon we've all imagined: a black hole devouring a star.
A black hole at the center of a galaxy about 2.7 billion light-years away, one about the same size as the black hole at the center of our own Milky Way, was observed sucking the life out of a star. Interestingly, the scientists who observed the black hole's meal compared it to a shark: neither, says Ryan Chornock of Harvard-Smithsonian, are unstoppable eating machines.

Two Hundred Years of Surgery
Surgery is a profession defined by its authority to cure by means of bodily invasion. The brutality and risks of opening a living person's body have long been apparent, the benefits only slowly and haltingly worked out. Nonetheless, over the past two centuries, surgery has become radically more effective, and its violence substantially reduced — changes that have proved central to the development of mankind's abilities to heal the sick.

College Dropout Became Mathematical Genius After Mugging
Real ‘Beautiful Mind’: College Dropout Became Mathematical Genius After Mugging -- ABC News
Working behind the counter at a futon store in Tacoma, Wash., is not the place you would expect to find a man some call a mathematical genius of unprecedented proportions.
Jason Padgett, 41, sees complex mathematical formulas everywhere he looks and turns them into stunning, intricate diagrams he can draw by hand. He’s the only person in the world known to have this incredible skill, which he obtained by sheer accident just a decade ago.

Spychips For Soldiers
U.S. Military Developing Spychips For Soldiers -- WND
Government wants 'health' benefits from nanosensors.
The U.S. military wants to plant nanosensors in soldiers to monitor health on future battlefields and immediately respond to needs, but a privacy expert warns the step is just one more down the road to computer chips for all.
“It’s never going to happen that the government at gunpoint says, ‘You’re going to have a tracking chip,’” said Katherine Albrecht, who with Liz McIntyre authored “Spychips,” a book that warns of the threat to privacy posed by Radio Frequency Identification.

My Comment: It is easy to foresee that one day these chips will be in all of us.
Is Space Weather A National Security Threat?

Space Weather Expert Has Ominous Forecast -- L.A. Times
Mike Hapgood, who studies solar events, says the world isn't prepared for a truly damaging storm. And one could happen soon.
A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt.
This isn't the premise of the latest doomsday thriller. Massive solar storms have happened before — and another one is likely to occur soon, according to Mike Hapgood, a space weather scientist at the Rutherford Appleton Laboratory near Oxford, England.

My Comment: A giant space storm that knocks-off the world's electrical and communications grid system will be a disaster .... but not a catastrophic one. We will survive .... but trust me .... it is not going to be easy. I should know .... I lived through the Ice Storm of 1998 in Montreal .... an ice storm that knocked-off the electrical grid for a week in my part of Montreal, and longer in the south of Montreal (some regions had no power for a month) .... and before I forget .... this all happened in the middle winter when temperatures outside can easily reach (and did) -20C. We (of course) all survived .... but it was a difficult time, and what bothered me most was the lack of news and information.

How Red Wine Prolongs Life
How Red Wine Prolongs Life: Scientists Uncover How 'Miracle Ingredient' Boosts Body’s Cell Energy -- Daily Mail
Scientists claim to have discovered the secret of how an ingredient in red wine could be the key to a longer life.
The ‘miracle ingredient’ resveratrol credited with anti-ageing powers, and the ability to work against cancer, heart disease and obesity, really does boost the body’s supply of cell energy, claim researchers.
But it is only ‘switched on’ in the presence of a gene called SIRT1 that is the key to longevity and energy.

Physicists Crack Fusion Mystery -- Technology Review
A new theory might help researchers double the power of fusion reactors.
One reason it's taking decades to develop fusion reactors that can generate electricity is that physicists don't completely understand what's going on in the high-temperature plasma inside a reactor. Under certain conditions, the plasma—which is where fusion reactions take place—disappears in under a millisecond.

How Black Holes Work
Johns Hopkins Astronomer Discovers How Black Holes Work -- CBS
BALTIMORE (WJZ)– Johns Hopkins is again at the center of groundbreaking research. One of their astronomers had a simple idea, and as Mike Schuh reports, it led to a once in a lifetime discovery about black holes.
Black holes are out there sucking up stars like cosmic vacuum cleaners. But they’re invisible. We’ve never seen them work in real time… until now. A Hopkins-led team found a star caught by a black hole’s gravity.

Time-Lapse Video Shows Construction Of New York's Tallest Tower
Time-Lapse Video Shows Construction Of New York's Tallest Tower -- The Telegraph
A time-lapse video recorded over a seven-year period was released on Monday as One World Trade Center was officially recognised as the tallest skyscraper in New York City.
The two-minute recording details the construction of the tower from its bare concrete foundations in 2004 to the monumental glass tower as it stands today.
The milestone was recognised as workers erected a 12-ton steel column onto the top deck of the building, giving it a height of a little over 1,250ft – marginally taller than the Empire State Building.

Iran Preparing To Cut Internet Access To Rest Of World
Iran Planning To Cut Internet Access To Rest Of World -- The Telegraph
Iran is drawing up plans to cut off its internet users from the rest of the world with a so-called Halal or "clean" internet.
Iranians are already used to censors blocking Facebook, Gmail and foreign news sites, and being spied on with surveillance software purchased from Western companies.
But the ambitious plans would go much further, blocking access to foreign-based social media sites and email. Instead, there will be an Iranian version of Facebook and a new email service, to be called Iran Mail. Users will have to register their home address and social security number with police.

My Comment: It's hard to contemplate living in what is essentially a modern religious dictatorship .... but that's the life for all Iranians.

China's Space Know-How Said Threat To U.S., Taiwan -- Reuters
China's growing capabilities in space could undercut any U.S. military response if Beijing resorted to force to bring self-ruled Taiwan into its fold, a study released Friday by a congressionally mandated U.S. commission said.
China's military is rapidly boosting its space programs to advance Communist Party interests "and defend against perceived challenges to sovereignty and territorial integrity," said the 84-page report by the Project 2049 Institute, a research group on Asia-Pacific security issues.

My Comment: On the same day that this report on China's growing space program was released, America's space program decline was there for all to see.
Women And Swimsuits
Why Do Women Cringe At The Thought Of Trying On Swimsuits? -- Red Orbit
Swimsuit season may not entirely be starting yet, but women all over the world are feeling the effects of it. It is intimidating for any girl to wear a bathing suit in public, but even more so in private dressing rooms. Dressing rooms can be cramped with bad lighting, making females unknowingly put more pressure on themselves through self-scrutiny. This idea of self-reflection through a variety of forms of clothing, from swimsuits to jeans and a sweater, was recently highlighted in an experiment by psychologists at Flinders University in Adelaide, Australia.
The study, which will be published in the May issue of the journal Sex Roles, focuses on the idea of “self-objectification.”
