Los Alamos Nuclear Laboratory Remains Closed As Wildfires Threaten Facility
Los Alamos Fire: EPA Testing for Radiation -- ABC News
The wildfire that surrounds the nuclear lab in Los Alamos, New Mexico, has grown to at least 61,000 acres amid mounting concerns about what might be in the smoke that's visible from space.
Such fear has prompted the Environmental Protection Agency to bring in air monitors, along with a special airplane that checks for radiation levels. So far officials have not been able to find anything.
"Our facilities and nuclear material are protected and safe," Laboratory Director Dr. Charles McMillan told ABC News.

A Look At Cyberwarfare And Hackers From A Russian Perspective
Evgeny Kaspersky was trained as a cryptologist and went on to co-found Kapersky Labs, which makes antivirus, anti-spyware, anti-spam and other online security products. In a recent SPIEGEL interview, he discussed a number of what he sees as worrying trends in cyber security. Regarding the new era of cyber war, he stated: "This war can't be won; it only has perpetrators and victims. Out there, all we can do is prevent everything from spinning out of control. Only two things could solve this for good, and both of them are undesirable: to ban computers -- or people." Sergei Chirikov/ AFP/ Getty Images'I Fear the Net Will Soon Become a War Zone'. An Interview With Anti-Virus Pioneer Evgeny Kaspersky -- Spiegel Online
Evgeny Kaspersky is one of Russia's top Internet virus hunters and IT entrepreneurs. In a SPIEGEL interview, he discusses a raft of recent hacker attacks on multinationals, the "total professionals" behind the Stuxnet virus and his fear of both personal and widespread cyber violence.

Google Earth Goes Under the Sea
From Popular Science:
Google Earth broke new ground (new water?) when they took the world of virtual-earth-exploring into the oceans. Of course, the oceans are kind of big. They fill up nearly three-quarters of the earth's surface area, and most of that area hasn't been mapped out. But now you can tour roughly half of the known area without pulling on any SCUBA gear, thanks to Google's new underwater terrain explorer.

Commentary On Europe's Organic Food Scare
Europe's Organic Food Scare -- Wall Street Journal
German Greens and their European Union acolytes have long fought scientific advances in food production and protection. After a spice manufacturer in Stuttgart employed the world's first commercial food irradiation in 1957, West Germany banned the practice in 1959 and has since allowed few exceptions. So it's no small scandal that the latest fatal E. coli outbreak has been linked to an organic German farm that shuns modern farming techniques.

What Could A Solar Flare Do To Us?
CME NASA When The Sun Unleashed Its Plasma Blast This Week, Earth Got Lucky -- Popular Science
What a predicted 2013 blast from the sun could mean for the U.S.
On Tuesday, the biggest solar flare in four years erupted from the sun, sending a mass of charged particles hurtling towards Earth. NASA announced that it was an M-2 (medium-sized) flare and an S1-class (minor) radiation storm. The electromagnetic pulse it induced created amazing auroras, but it could also damage satellites and radio communications. What would happen with an even stronger, larger flare? Something terrible...

A report in April suggesting a giant atom smasher may have detected a never-seen-before subatomic particle had physicists at the edge of their seats with hope, albeit with a healthy dose of skepticism. Now an independent test of the results suggests it was just a fluke.
The tantalizing signal came from the Tevatron particle accelerator at the Fermilab physics laboratory in Batavia, Ill. Inside the accelerator there, particles race around a 4-mile (6.3 km) ring at near light speed. When two particles collide, they disintegrate into other exotic particles in a powerful outpouring of energy. [Wacky Physics: The Coolest Little Particles in Nature]

China's Drought Is Impacting World's Food Supplies
How Will China's Food Supply Weather the Year of Drought? -- Time
In China food supplies and food prices are deeply sensitive topics. So by the time the U.N.'s Food and Agriculture Organization issued a special alert warning in February that a prolonged drought in the North China Plain was a “potentially serious problem” for the country's winter wheat crop, China's leaders had already mobilized. President Hu Jintao and Premier Wen Jiabao made visits to farming regions in north China, pledging cash, equipment and manpower to ensure the crop survived.

The circuit can compute the square root of numbers up to 15, though very slowly. (Lulu Qian / Caltech / June 2, 2011)Research Marks A Leap Forward For DNA-Based Computers -- L.A. Times
A system involving 74 DNA strands can calculate square roots of numbers up to 15, though very slowly. Scientists say the goal is to devise computers that can interact directly with living cells — and perhaps fight disease.
Caltech researchers have produced the most sophisticated DNA-based computer yet, a wet chemistry system that can calculate the square roots of numbers as high as 15.
The system is composed of 74 strands of DNA that make up 12 logic gates comparable to those in a silicon-based computer, the researchers reported Thursday in the journal Science. But the system operates a little more slowly than a conventional computer: It takes as much as 10 hours to obtain each result.

Why We Need A Good Night’s Sleep
A Good Night’s Sleep Isn’t a Luxury; It’s a Necessity -- New York Times
In my younger years, I regarded sleep as a necessary evil, nature’s way of thwarting my desire to cram as many activities into a 24-hour day as possible. I frequently flew the red-eye from California, for instance, sailing (or so I thought) through the next day on less than four hours of uncomfortable sleep.
But my neglect was costing me in ways that I did not fully appreciate. My husband called our nights at the ballet and theater “Jane’s most expensive naps.” Eventually we relinquished our subscriptions. Driving, too, was dicey: twice I fell asleep at the wheel, narrowly avoiding disaster. I realize now that I was living in a state of chronic sleep deprivation.

Findings contradict long-held theory that a plume directly fuels Hawaii.
Hawaii's traditional birth story—that the volcanic islands were, and are, fueled by a hot-rock plume running directly to Earth's scorching core—could be toast, a new study hints.

ScienceDaily (May 26, 2011) — There is water inside the moon -- so much, in fact, that in some places it rivals the amount of water found within Earth.
The finding from a scientific team including Brown University comes from the first-ever measurements of water in lunar melt inclusions. Those measurements show that some parts of the lunar mantle have as much water as Earth's upper mantle.

Babies are sophisticated mini-statisticians, a new study finds, capable of making judgments about the probability of an event they've never seen before.
Using a computer model, researchers were able to accurately predict what a baby would know about a particular event if given certain information. The model may be useful in engineering artificial intelligence that reacts appropriately to the world, said study researcher Josh Tenenbaum, a cognitive scientist at the Massachusetts Institute of Technology. The study also demonstrates just how savvy baby brains are, Tenenbaum told LiveScience.

THE discovery of the remains of an aristocratic Scottish "Amazon", killed in battle during the Wars of Independence, is set to rewrite the history books.
Her skeleton was among the remains of five "high status" individuals - all of whom had suffered violent deaths - found beneath the paved floor of the "lost" Royal Chapel at Stirling Castle.

Robot's Supersonic Air Jets Allow It To Climb Most Surfaces
Video: Robot's Supersonic Air Jets Allow It To Climb Just About Any Surface -- Popular Science
Many wall-walking robots mimic natural adhesives--like the sticky feet of geckos--to remain fixed to a surface while they scale it.
But this little bot uses nothing but a supersonic version of a well-known principle of fluid dynamics to cling to just about any surface--without the surface of its grippers ever actually touching it.

KENNEDY SPACE CENTER, Fla.--A version of the Bush administration's Orion moon capsule, written off by the Obama administration and then resurrected as a space station lifeboat, will be developed instead for use in future manned flights to deep space targets beyond Earth orbit, the agency announced today.
Douglas Cooke, associate administrator of NASA's Exploration Systems Mission Directorate, told reporters the Orion concept, described by former NASA Administrator Mike Griffin as "Apollo on steroids," is the most capable spacecraft currently on the drawing board for meeting the Obama administration's "flexible path" approach to deep space exploration.

U.S. Congress Getting Ready To Tax The Internet
How Will States Tax Internet Downloads? Congress May Decide -- EpicenterHere’s an interesting conundrum, posed by Representative Dennis Ross (R-Florida), at a House Judiciary subcommittee hearing held on Monday:
“Imagine you are sitting in Dulles airport in Virginia, waiting for a flight back to Florida,” Ross began in his opening remarks. “You download a music file from Apple, which is headquartered in California. The music is sent to you via a server in Oklahoma.”
Which of these states should be allowed to tax the sale?
Without a “clear national rule,” he warned at the hearing, “all four states may attempt to tax the transaction.”

My Comment: Another tax grab .... get ready for it.
NASA's Mars Rover Spirit To Be Shut Down
NASA's Mars rover Spirit, shown in an artist's rendering, was expected to serve a three-month mission, but it provided scientists with a trove of information over more than six years of operation. (Reuters)NASA Rover Spirit 'Revolutionized' How We See Mars -- L.A. Times
As the Martian rover falls silent for good, JPL scientists mourn Spirit's loss and celebrate its remarkable achievements that continued for years beyond its expected lifetime.
It was supposed to roam the surface of Mars for only three months and cover a distance of just a few hundred yards. Instead, NASA's Spirit rover traveled nearly five miles over five years, finding geological evidence that the Red Planet had once been warm and wet enough to have harbored life. Even after it got hopelessly stuck in the powdery soil of Gusev crater, the rover continued to make discoveries and beamed them to scientists millions of miles away.

Smallpox Eradication Decision Is Deferred Again
Smallpox-Destruction Deadline Delayed For 3 Years -- Wall Street Journal
Global health officials delayed setting a deadline Tuesday for destroying the last known stocks of smallpox for at least three years, a compromise that will enable the U.S. and Russia to continue researching medications to counter a bioterror attack.
The consensus at the World Health Assembly, the decision-making body of the World Health Organization, came after a contentious debate stretching over two days. It represents a compromise for the U.S., Russia and more than two dozen other countries that wanted to keep the virus stocks for at least another five years. Iran, China, Thailand and other countries objected to that timetable and some of its provisions.

It Seems That Man Has Been At War With His Fellow Man For A Very Long Time
Bronze Age relic: Archaeologists have found the remains of around 100 bodies in the Tollense Valley in northern Germany, including this fractured skull'Earliest' Bronze Age Battle Site Containing 100 Bodies Found On German River Bank -- The Daily Mail
Fractured skulls and broken bones found on a German river bank could point to the earliest site of a Bronze Age battle ever discovered.
Archaeologists uncovered the remains of around 100 bodies in the Tollense Valley in northern Germany, suggesting brutal hand-to-hand combat between warring tribes.
Bones had been battered, skulls were fractured and one body has an arrowhead buried more than 2cm inside it.

My Comment: On the one hand, such a discovery is fascinating and informative of how we interacted (and fought) in ancient times. On the other hand .... it is depressing to know that our culture and approach to war has not changed .... with the exception that we now have better weapons.
Lots Of Multi-Planet Systems Found In Kepler Planet Hunt
This artist rendering provided by NASA shows a solar system comparison of the Kepler 11 solar system and ours. NASA/APSurprise Find In Kepler Planet Hunt: Lots Of Multi-Planet Systems -- Christian Science Monitor
NASA's Kepler spacecraft, which is searching for Earth-mass planets orbiting sun-like stars, is finding hundreds of candidate planets, and many more multi-planet systems than expected.
Two years into a 3-1/2-year mission, NASA’s Kepler spacecraft, hunting for planets orbiting some 165,000 stars in the constellation Cygnus, is uncovering planet candidates by the hundreds.
Many of these inhabit multi-planet systems that are unexpectedly flat – the inclination of the planets’ orbits within each of these systems are essentially the same, a feature that may hold clues about how these systems formed and evolved.

KENNEDY SPACE CENTER, Fla. - After a close-up, focused inspection of a damaged heat shield tile on the belly of space shuttle Endeavour, NASA analysts have concluded that there is no threat posed to the orbiter, and NASA's Mission Management Team cleared the ship for re-entry as-is.
"So all good results all the way around," said MMT Chairman LeRoy Cain. "We're essentially clearing the vehicle for re-entry at this point. There were no dissenting opinions, no alternate opinions; the entire team was pretty much on board with the assessments that were done."

Free-Floating "Planets" Are More Common Than What Is Believed
The "rogue" planets act as lenses, bending the light from distant stars'Free-Floating' Planets Found With No Star In Sight -- BBC
An international team of astronomers claim to have found free-floating "planets" which do not seem to orbit a star.
Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way.
The objects revealed themselves by bending the light of more distant stars, an effect called "gravitational microlensing".
