Why Kids Ask Why
From Live Science:
A child's never-ending "why's" aren't meant to exasperate parents, scientists say. Rather, the kiddy queries are genuine attempts at getting at the truth, and tots respond better to some answers than others.
This new finding, based on a two-part study involving children ages 2 to 5, also suggests they are much more active about their knowledge-gathering than previously thought.
"Even from really early on when they start asking these how and why questions, they are asking them in order to get explanations," lead researcher Brandy Frazier of the University of Michigan told Live Science.

How Long Can a Nuclear Reactor Last?
OLDIE BUT GOODIE: Extending the life span of aging nuclear power plants could be essential to meet the nation's energy needs. WIKIMEDIA COMMONS/GREUDIN
From Scientific American:
Industry experts argue old reactors could last another 50 years, or more.
Could nuclear power plants last as long as the Hoover Dam?
Increasingly dependable and emitting few greenhouse gases, the U.S. fleet of nuclear power plants will likely run for another 50 or even 70 years before it is retired -- long past the 40-year life span planned decades ago -- according to industry executives, regulators and scientists.

High-Fliers Swear A 5am Start Is The Key To Success
Photo: Yawn chorus: Is 5am a productive time to begin the day?
From The Daily Mail:
But how do you do it all, I asked my high-powered friend Fiona, who had just reeled off her latest long list of projects. 'Oh, I get up at 5am,' she said. 'So by breakfast time, I've cleared emails, been through the diary and can hit the ground running.'
That did it. For years, I've heard people proclaim the advantages of early rising. Yoga teachers, life coaches and exercise gurus swear by its benefits for the body.
Over-achievers find it's the best time to get things done because their brains are fresh and ready for action.
Anna Wintour, the editor of American Vogue, famously rises at 5am to fit in an hour's tennis before her 6am blow-dry each day.

From The Guardian:
Woolly mammoths and other giant ice-age mammals faced extinction 2,000 years before deadly speartips were invented.
Woolly mammoths and other large, lumbering beasts faced extinction long before early humans perfected their skills as spearmakers, scientists say.
The prehistoric giants began their precipitous decline nearly 2,000 years before our ancestors turned stone fragments into sophisticated spearpoints at the end of the last ice age.

Google Chrome OS: Why Should People Switch?
Google Chrome OS isn't scheduled to arrive for another year, but Google has a lot to do before then to make the project attractive to the average user. (Google Chrome OS screenshot)
From The Christian Science Monitor:
Google Chrome OS has buzz now, but a number of stars will have to align for many folks to migrate to it.
Will you be using Chrome OS a year from now?
At the Web-based operating system’s coming-out party at Google headquarters on Thursday, Google presented its vision of Chrome, and a huge amount of information on what the browser and operating system are based on, how they run, and the safeguards in place to ensure they run well. But missing in all of that, at least to this observer, was a clear exposition of how Google plans to get users onboard – in essence, the hook.

U.S. Exhausted Oil And Gas Supplies — Repeatedly -- A Commentary
From The Houston Chronicle:
What city contributed most to the making of the modern world? The Paris of the Enlightenment and then of Napoleon, pioneer of mass armies and nationalist statism? London, seat of parliamentary democracy and center of finance? Or perhaps Titusville, Pa.
Oil seeping from the ground there was collected for medicinal purposes — until Edwin Drake drilled and 150 years ago — Aug. 27, 1859 — found the basis of our world, 69 feet below the surface of Pennsylvania, which oil historian Daniel Yergin calls “the Saudi Arabia of 19th-century oil.”
For many years, most oil was used for lighting and lubrication, and the amounts extracted were modest. Then in 1901, a new well named for an East Texas hillock, Spindletop, began gushing more per day than all other U.S. wells combined.
Since then, America has exhausted its hydrocarbon supplies.
Repeatedly.

How 16 Ships Create As Much Pollution As All The Cars In The World
From The Daily Mail:
Last week it was revealed that 54 oil tankers are anchored off the coast of Britain, refusing to unload their fuel until prices have risen.
But that is not the only scandal in the shipping world. Today award-winning science writer Fred Pearce – environmental consultant to New Scientist and author of Confessions Of An Eco Sinner – reveals that the super-ships that keep the West in everything from Christmas gifts to computers pump out killer chemicals linked to thousands of deaths because of the filthy fuel they use.

Acid Oceans Leave Fish At More Risk From Predators
From The BBC:
Ocean acidification could cause fish to become "fatally attracted" to their predators, according to scientists.
A team studying the effects of acidification - caused by dissolved CO2 - on ocean reefs found that it leaves fish unable to "smell danger".
Young clownfish that were reared in the acidified water became attracted to rather than repelled by the chemical signals released by predatory fish.
The findings were published in the journal Ecology Letters.

Bing: Google Gets Some Real Competition
From the Christian Science Monitor:
It’s hard to compete when your opponent’s name is so popular that it’s become a verb. Such is the plight of every search engine that dares to challenge Google.
Last year, four search engines made up more than 95 percent of all search traffic: Google, Yahoo, MSN, and Ask. Only Google increased its share of the pie that year, eating up 67 percent of all searches in January and 72 percent by 2009, according to the online traffic monitor Hitwise.

A Look At Global Warming Written In A Cooler And More Skeptical Time, Giving Us A Better Understanding Of Climate Science
Hackers targeted the University of East Anglia's Climatic Research Unit, pictured, and published sensitive emails on the internet. Photo from The Daily Mail.
From Fabius Maximus:
The hacked emails and papers from the UK’s Climate Research Unit reveal the underside of climate science (as the many bizarre conclusions do the same for the anti-AGW mob). Spinning data to conceal contrary evidence, avoiding freedom of information requests, purging the profession of skeptical voices. All familiar things to anyone familiar with the history of science. All evidence of the most important step needed, and that most strongly opposed by most climate scientists:
Raise the standards when applying science research to public policy questions. That means requiring full transparency of data and methods used in climate science research, and third party review of the data, analysis, and models.

Were Rats Behind Easter Island Mystery?
Moai statues on Easter Island, or Rapa Nui, among the most remote spots on Earth.
By Jayne Clark, USA TODAY
By Jayne Clark, USA TODAY
From USA Today:
Easter Island's mystery — brooding statues atop a treeless Polynesian island — fascinates tourists and scholars alike.
And inspires debate.
"Who or what destroyed the ancient palm woodland on Rapa Nui (Easter Island)?" ask German ecologists Andreas Mieth and Hans-Rudolf Bork, in an upcoming paper in the Journal of Archaeological Science. "The circumstances, causes and triggers of these environmental changes are the subject of persistent scientific discussion."
