Air Force Space Command Is Looking For A Few Good Cyber Warriors
The Air Force’s top cyber commander warned Thursday that the military may have a tough time finding all the qualified people it needs to stay ahead in the increasingly important world of attacking and defending networks.
Gen. William Shelton, head of Air Force Space Command, said that only a small percentage of people graduate with technical college degrees every year in the U.S. and of those an even smaller percentage are eligible to get the security clearance they’d need to become Defense Department or government cyber-operators.

This Months Solar Flare 'Likely Knocked' Military Satellites Offline
An M7.9 class flare. A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events.
Solar Flares Likely Knocked Military Satellites Offline -- US News and World Report
Solar storms earlier this month may have caused military satellites to reboot.
Despite being made to withstand radiation emitted from solar flares, a storm caused by the sun earlier this month may have temporarily knocked American military satellites offline, according to General William Shelton, head of the Air Force's Space Command.
The energy particles associated with two solar storms March 9 and 10 may have caused what are called "single event upsets" on military satellites. "The timing is such that we say this was likely due to [solar radiation]," Shelton told reporters at a Defense Writers Group breakfast Thursday. Although it's impossible to tell exactly what caused the events—essentially a temporary reboot of satellite instrumentation software—solar storms are known to wreak havoc on satellites.

Germany Unprepared For Major Nuclear Disaster -- Spiegel Online
If a nuclear disaster comparable to Fukushima were to hit a German nuclear plant, authorities would be unprepared to handle it, and scientific projections show that radiation would likely spread much further than previous estimates. But government agencies have done little to address the problem. Critics call the delay a "scandal."
The projected catastrophe would begin on the cold winter's day of Dec. 1, 2010. In the scenario envisioned by scientists, fuel elements begin melting at the Philippsburg 2 nuclear power plant in the southwestern German state of Baden-Württemberg. Engineers release pressure to prevent the plant from exploding, and for the next 25 days, radioactive clouds move north toward the Rhine Valley, over the cities of Speyer and Hockenheim, toward Mannheim and Heidelberg.

My Comment: Hmmmm .... I doubt that anyone can really be prepared for a major nuclear disaster.

Microsoft Co-Founder Paul Allen Invests $300 Million Into Mapping the Brain -- Popular Science
Paul Allen’s commitment to tackling big questions in neuroscience grows larger still. The Microsoft co-founder has already contributed hundreds of millions of dollars to brain science, much of it to the establishment of the Allen Brain Institute, a nonprofit charged with building a massive database of information about the brain. Now, seemingly from a frustration with the slow pace of discovery elsewhere in the field, Allen has committed another $300 million over the next decade to expanding his institute to include it’s own lab for neuroscience investigation.

Americans Now Watch More Online Movies Than DVDs -- CNN
NEW YORK (CNNMoney) -- U.S. movie buffs will pay to watch more movies online in 2012 than they will on physical video formats like DVD. That historic first marks a tipping point for Hollywood -- and its business model.
The stat comes a report that research firm IHS iSuppli released late Thursday. Online views, or paid "transactions," will hit 3.4 billion this year, compared with 2.4 billion for physical copies, according to IHS's forecast.

Have Americans Forgotten About AIDS?
The Global Epidemic the U.S. Forgot -- Yahoo News/ABC
Like a brush fire, The HIV/AIDS epidemic has spread across the world over the last 30 years, picking up steam in certain areas and losing steam in others. Why?
While rates of infection in Western nations have gone down, there has been an explosion of cases in sub-Saharan Africa, India, China and parts of Russia.
In this two week Around the World special, Christiane Amanpour takes an in depth look at the illness that has defined an era, a disease that strikes fear in all of us.

Water Wars Between Countries Could Be Just Around The Corner, Davey Warns -- The Guardian
Energy secretary tells conference that growing pressure on water resources could worsen existing war and lead to new ones
Water wars could be a real prospect in coming years as states struggle with the effects of climate change, growing demand for water and declining resources, the secretary of state for energy and climate change warned on Thursday.
Ed Davey told a conference of high-ranking politicians and diplomats from around the world that although water had not been a direct cause of wars in the past, growing pressure on the resource if climate change is allowed to take hold, together with the pressure on food and other resources, could lead to new sources of conflict and the worsening of existing conflicts.

My Comment: Conflicts and wars over water is nothing new in human history. All empires and great powers have always had their main cities near sources of water .... whether by the sea and/or by a major river. Cutting off these sources of water will guarantee conflict and war, and with water becoming a precious resource in the 21rst century .... wars over fresh water will probably be the eventual outcome.

Seven Brilliant Lectures By Richard Feynman (Video)
Watch A Series Of Seven Brilliant Lectures By Richard Feynman -- io9
Richard Feynman was obviously famous for his work as a physicist, but he's also widely regarded as one of the most lucid and effective lecturers to ever address an audience. So renowned, so readily accessible were his presentations, that his introductory physics lectures (which he delivered to undergraduates at Caltech) have since been immortalized in the form of a three-volume set called, quite simply, The Feynman Lectures.

Why Women Moan During Sex -- CNN
Ian Kerner, a sexuality counselor and New York Times best-selling author, blogs about sex weekly on The Chart. Read more from him on his website, GoodInBed.All you have to do is watch nearly any depiction of female orgasm on screen to get an idea of how a woman is “supposed” to react during sex.
From "When Harry Met Sally" to "Sex and the City" to your basic porn film, women in the throes of passion aren’t just shouting their ecstasy from the rooftops - they’re moaning with pleasure. Loudly.
But is this just cinematic license, or is there really something to noisy sex?

How Many X-37Bs Are There?
Just How Many X-37Bs Are There? -- Defense Tech
So Air Force Space Command boss Gen. William Shelton gave us a tiny bit more insight into the service’s super secret space spycraft, the X-37B, when he said that it’s doing its super secret — and year-long — mission excellently and that there’s no need for a bigger version of it or to increase the size of the X-37B fleet.
What was really interesting about his comments, was the fact that he wouldn’t say just how big the fleet is. Keep in mind that the service has said that it’s got two of the mini-shuttles for a while now, but Shelton’s response to a question about the size of the fleet raised more questions than it answered.

James Cameron Descends To The Bottom Of The Mariana Trench -- The Telegraph
James Cameron, the multi-millionaire Hollywood film director behind Titanic and Avatar, is heading to the bottom of the Mariana Trench in person armed with hi-tech 3D cameras and lights that will capture the moment for cinemagoers.
Fewer people have reached the deepest point in the world's oceans than have walked on the moon, but the obscure worms and tiny crustaceans that reside there are receiving an unlikely visitor.
Cameron set out from the tiny Pacific island of Guam for the Mariana Trench, and is descending more than seven miles straight down in a lime green reinforced submersible, the first ever solo mission to the lowest point on Earth.
Cameron’s 24ft long vertical capsule, The Deepsea Challenger, weighs 11 tons and was built amid great secrecy in Australia over the last eight years.

Red Meat Halves Risk Of Depression -- The Telegraph
Women who reduce lamb and beef in their diets are more likely to suffer depression, according to the new study.
Experts admitted surprise at the findings because so many other studies have linked red meat to physical health risks.
The team made the link after a study of 1000 Australian women.
Professor Felice Jacka, who led the research by Deakin University, Victoria, said: "We had originally thought that red meat might not be good for mental health but it turns out that it actually may be quite important.

Why Taking A Vacation Is Good For You
The Benefits Of Taking Time Off -- US News And World Report/Inside Science
Taking a vacation may not only make you happy, but increase your job performance.
(ISNS)—Rae and Bruce Hostetler not only work very hard, they also relax just as well. Numerous vacations help the suburban Indianapolis couple to maintain their health and emotional well-being—and it's no surprise to health care professionals.
"Rest, relaxation, and stress reduction are very important for people's well-being and health. This can be accomplished through daily activities, such as exercise and meditation, but vacation is an important part of this as well," said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction times as some of the benefits from taking some time off.
"We also know that the mind is very powerful and can help with healing, so a rested, relaxed mind is able to help the body heal better," said Withers.

NSA Chief Denies To Congress That They Are Conducting Domestic Spying
In a rare break from the NSA’s tradition of listening but not speaking, NSA chief General Keith Alexander was grilled Tuesday on the topic of eavesdropping on Americans in front of a House subcommittee.
The questioning from Rep. Hank Johnson (D-Georgia) was prompted by Wired’s cover story this month on the NSA’s growing reach and capabilities, but leaves Americans with as many questions about the reach of spy agency’s powers as they had before Alexander spoke.
Alexander denied, in carefully parsed words, that the NSA has the power to monitor Americans’ communications without getting a court warrant.

My Comment: The NSA chief is very careful with his words .... it appears that he has his own definition of spying and eavesdropping.

Navy Opens 'Hunger Games' Arena For Military Robots -- Live Science
A new U.S. Navy lab can track every movement of battlefield robots as they struggle to survive arenas built to resemble scorching deserts, wave-pounded shores and tropical rain forests.
The lab's biggest environment has high-speed video cameras that automatically swivel to follow up to 50 ground robots, flying drones and even human soldiers. Such intense surveillance of man-made survival settings may remind science fiction readers of "The Hunger Games" — a popular book series turned Hollywood film(s) where "game makers" construct huge, naturalistic arenas to feature reality television displays of battles to the death.

How Quake-Prone Is The Mexico?
Mexico Earthquake: How Quake-Prone Is The Region? -- Christian Science Monitor
Mexico earthquake history shows that the same faults that caused Tuesday's Mexico earthquake can produce even bigger events, like one that struck in 1985.
Authorities in Mexico are surveying that damage following a magnitude 7.4 quake that struck the country just after noon on Tuesday local time.
The quake was centered some 31 miles north-northeast of the city of Ometepec, in a mountainous region dotted with villages. The rupture occurred at a depth of about 12 miles, according to estimates from the US Geological Survey's Earthquake Information Center in Golden, Colo.
