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?

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.

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.

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.

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.

If 2009 was dominated by touch technology then 2010 looks set to be the year of 3D.

3D has been one of the biggest hits of the cinemas this year and it is likely to continue its stride into other mediums during 2010, experts agree.

TV manufacturer LG wants to sell nearly half a million 3D-ready TV sets next year as the World Cup kicks off in the format.

Meanwhile laptops and games consoles are also getting a 3D makeover.

Acer has already released what it is claiming is the world's first 3D-capable laptop, and most agree it will be the first of many.

To find worlds within the "Goldilocks" zone, where conditions to support life are just right, look no further than our own solar system.

The holy grail for finding worlds beyond Earth that are hospitable to life has been planets just the right distance from their mother stars where liquid water can exist on the surface -- the so-called "Goldilocks" zone.

But scientists now say this elusive zone where conditions are not too hot and not too cold for life to exist is far bigger than originally thought.

NASA on Tuesday selected three finalists to be the agency’s next cheap, robotic exploration mission. Depending on which wins, a probe will head for Venus, the moon, or a near-Earth object no later than 2018.

The latter two missions would include the return of samples, while the Venusian lander would test the planet’s composition much like the Phoenix Lander did on Mars. The NASA anointing means that the teams proposing the excursions will have some money to make more detailed plans.

Neighborhood planets such as Mercury and Jupiter received makeovers in both a scientific and literal sense. The discovery of water on the moon and Mars provided clues to the past, not to mention hints for the future of space exploration. A class of newly-detected "Super-Earth" planets around alien stars may ultimately prove more habitable than Earth.

Near The Edge Of The Solar System, Voyager 2 Finds Magnetic Fluff

Of course, this fluff isn’t made from the dust bunnies you find under your bed, the ‘Local Fluff’ (a nickname for the Local Interstellar Cloud) is a vast, wispy cloud of hot hydrogen and helium stretching 30 light-years across [Discovery News]. Astronomers already knew this fluff was out there near the boundary area between our solar system and interstellar space.

Flowing in salt-water ­channels beneath the surface is the world's largest supply of lithium--and, possibly, the future of transportation. Lithium is the key ingredient in the lithium-ion batteries that will power the electric vehicles that will soon be rolling off production lines worldwide.

Why Some Continue To Eat When Full: Researchers Find Clues

From Science Daily:

Science Daily (Dec. 28, 2009) — The premise that hunger makes food look more appealing is a widely held belief -- just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet.

Prior research studies have suggested that the so-called hunger hormone ghrelin, which the body produces when it's hungry, might act on the brain to trigger this behavior. New research in mice by UT Southwestern Medical Center scientists suggest that ghrelin might also work in the brain to make some people keep eating "pleasurable" foods when they're already full.
