Obama Set to Launch Vision For NASA

From USA Today:

WASHINGTON — President Obama will chart a course for NASA within weeks, based on the advice of a handful of key advisers in the administration and Congress.

Obama, who met Dec. 16 with NASA Administrator Charles Bolden, hasn't said when or how he'll announce his new policy.

The announcement likely will come by the time the president releases his fiscal 2011 budget in early February, because he must decide how much money the space agency should get.

From The Independent:

Neodymium is one of 17 metals crucial to green technology. There’s only one snag – China produces 97% of the world’s supply. And they’re not selling.

Britain and other Western countries risk running out of supplies of certain highly sought-after rare metals that are vital to a host of green technologies, amid growing evidence that China, which has a monopoly on global production, is set to choke off exports of valuable compounds.

Cracking The Majorana Code

From New Scientist:

A brilliant but fiercely eccentric Sicilian nuclear physicist writes a string of suicide notes, then disappears. He is never seen again. Yet he was carrying his passport and enough cash to start a new life.

Were the notes a clever decoy?

For decades, João Magueijo, a professor of theoretical physics at Imperial College London, has been obsessed by the story behind Ettore Majorana's disappearance.

"He's been with me throughout my scientific career as a shadow I've never been able to shake off," Magueijo declares in the prologue to A Brilliant Darkness. And so, to lay the ghost to rest, he has conducted his own investigation.

What And When Is Death?


From The New Atlantis:

All living things die. This is not new and it has nothing to do with technology. What is new in our technological age, however, is an uncertainty about when death has come for some human beings. These human beings, as an unintended consequence of efforts to prevent death, are left suspended at its threshold. Observing them in this state of suspension, we, the living, have a very hard time knowing what to think: Is the living being still among us? Is there still a present for this person or has the long reign of the past tense begun: Is he or was he? The phenomenon is popularly known as “brain death,” but the name is misleading. Death accepts no modifiers. There is only one death. Has it occurred or not? Alive or dead?

10 New Year's Resolutions To Keep You Alive


From Live Science:

Americans spend billions every year on a dizzying array of health schemes, but much of that money goes toward treatments and pills that do little if any good, or that mask underlying health issues by alleviating symptoms temporarily.

Meanwhile, some of the best approaches to health care are cheap and within your grasp, if only you can find the will to make some lifestyle changes.

If you're searching for a good New Year's resolution, here are 10 to pick from, along with the scientific reasons why you may want to actually keep them.

From CNET:

Sure, every blogger worth his salt has weighed in on the long-rumored Apple tablet that may or may not be--its possible size, shape, specs, debut date, and on and on. Now offering up a perspective on the matter is a high-profile tech industry executive, Kai-fu Lee, who until recently was the head of Google's China operations.

It seems that Lee, who's now working to foster entrepreneurship in China, wrote on his Chinese language blog earlier this week that Apple CEO Steve Jobs will be releasing a tablet PC in January, and expects to produce a voluminous 10 million in the first year, according to the IDG News Service and other media outlets.

Google Loses Canadian Groovle Domain Name Claim

From The BBC:

A Canadian company behind a search engine called Groovle.com has won a case filed against it by online search giant Google.

Google said the domain name used by the small business, 207 Media, was too similar to its own, but mediators the National Arbitration Forum disagreed.

In the complaint, Google asked for the judges to rule that 207 Media transfer the domain name over to it.

But three judges appointed by the forum refused the request.

They said the name was not similar enough to confuse people and the word 'groovle' was more closely linked to "groovy" or "groove" rather than Google.

Swine Flu Less Contagious Than Other Pandemic Strains

From USA Today:

MILWAUKEE (AP) — How contagious is swine flu? Less than the novel viruses that have caused big world outbreaks in the past, new research suggests.

If someone in your home has swine flu, your odds of catching it are about one in eight, although children are twice as susceptible as adults, the study found. It is one of the first big scientific attempts to find out how much the illness spreads in homes versus at work or school, and who is most at risk.

Once In A Blue Moon ... Stargazers Savour Spectacular Lunar Eclips On New Year's Eve

I see a blue moon rising. The moon above the University of Kansas, in the U.S.

From The Daily Mail:

Stargazers seeing out 2009 were treated to a spectacular 'blue moon' last night.

Blue moons occur about once every two and a half years, which is the origin of the saying 'once in a blue moon'. Furthermore a blue moon falling precisely on December 31st is extremely unusual.

The last time it happened was in 1990, and the next time won't be until 2028.

From the BBC:

Scientists have analysed DNA extracted from the remains of a 30,000-year-old European hunter-gatherer.

Studying the DNA of long-dead humans can open up a window into the evolution of our species (Homo sapiens).

But previous studies of this kind have been hampered by scientists' inability to distinguish between the ancient human DNA and modern contamination.

In Current Biology journal, a German-Russian team details how it was possible to overcome this hurdle.

No Rise of Atmospheric Carbon Dioxide Fraction In Past 160 Years, New Research Finds

New research finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades, contrary to some recent studies. (Credit: iStockphoto)

From Science Daily:

Science Daily (Dec. 31, 2009) — Most of the carbon dioxide emitted by human activity does not remain in the atmosphere, but is instead absorbed by the oceans and terrestrial ecosystems. In fact, only about 45 percent of emitted carbon dioxide stays in the atmosphere.

However, some studies have suggested that the ability of oceans and plants to absorb carbon dioxide recently may have begun to decline and that the airborne fraction of anthropogenic carbon dioxide emissions is therefore beginning to increase.

The Volcano Tourists: Mayon Threatens To Erupt... But Officials Stunned As Snap-Happy Visitors Defy Ban To See The Eruption

Lethal: Lava cascades down the Mount Mayon volcano in 2006

From The Daily Mail:

When a volcano erupts most people take to the hills and get as far away as possible.

But officials in the Philippines have expressed their amazement at the stupidity of tourists who are flocking in their thousands to fields around a dangerous volcano so they can photograph its spectacular lava flows.

Scientists say that Mount Mayon volcano is on the brink of erupting and anyone within a five-mile radius would probably be killed by lava raining down on them if it did.

From New Scientist:

IT WOULD be lovely to have access to chromatography," Spike Marchant tells me wistfully. As a science journalist, it's the kind of remark I expect to hear from the people I interview. But Marchant isn't a scientist, he's a bartender.

A very special breed of bartender, mind you. What Heston Blumenthal, Ferran Adrià and others have done for food, Marchant and his colleagues are aiming to do for booze. "We're not scientists but we use the ideas of scientists," says Tony Conigliaro, the creative force behind 69 Colebrook Row, a cosy cocktail bar in north London where I have come to learn about, and taste, the future of cocktails.

Are New TSA In-Flight Restrictions Pointless?

Spaceport security was tight in the sci-fi movie Total Recall. Unfortunately, modern-day airport security doesn't have this level of scanning technology (yet) (Columbia Pictures).

From Discovery News:

On Christmas Day, Nigerian wannabe terrorist Umar Farouk Abdulmutallab set fire to his pants on Northwest Airlines Flight 253 as it was on its final approach to Detroit Metropolitan Airport.

The fire was sparked when Abdulmutallab failed to detonate a homemade mix of explosives that were carried on board the aircraft concealed in the crotch of his underwear.

Blue Moon To Occur New Year's Eve

From Space.com:

New Year's Eve brings us the second of two full moons for North Americans this month. Some almanacs and calendars assert that when two full moons occur within a calendar month, that the second full moon is called the "blue moon."

The term has a very interesting history, riddled with misconceptions and errors. More on that lower down. First, what will (and won't) happen:

The full moon that night will likely look no different than any other full moon (other than the fact that a partial eclipse will occur across most of Europe, Africa, and Asia).
