From Science Daily:

Science Daily (Feb. 18, 2010) — When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet's molten interior and released them into the sky. However, some light elements got trapped inside the planet. In the journal Nature, a Rice University-based team of scientists is offering a new answer to a longstanding mystery: What caused Earth to hold its last breath?

New Transistors Mimic Human Brain's Synapses

From Live Science:

A new transistor designed to mimic structures in the human brain could pave the way for increasingly efficient computer systems that "think" like humans, scientists say.

The transistor is the first to mimic a crucial process used by brain cells, or neurons, when the cells signal one another.

Scientists Shed Light On Supernova Origins

Type Ia supernovae are thought to result when a white dwarf star in a binary system accumulates enough matter from its larger companion. When the white dwarf reaches the critical Chandrasekhar mass, about 1.4 times the mass of our Sun, high internal density and temperature ignite a thermonuclear explosion. Because the masses of Type Ia supernovae are similar, their brightnesses are similar. Berkeley Lab

From The L.A. Times:

The so-called Type 1a supernovae are key to measuring celestial distances. Astronomers find evidence that they're formed by the collision of two white dwarfs.

German astronomers using a U.S. telescope have provided scientists with at least a partial answer to a vexing question: What is the origin of the so-called Type 1a supernovae, which are widely used as celestial mileage markers?

Type 1a supernovae are of special significance to astronomers because all are believed to have essentially the same intrinsic brightness, and because they can be observed from great distances. Thus, by comparing the brightness of any one of them to what it is expected to be, researchers can estimate its distance from Earth and thereby judge the distance of objects near it.

From Cosmos/AFP:

WASHINGTON: Babies who hear two languages regularly when they are in their mother's womb are more open to being bilingual, a study published this week in Psychological Science shows.

Psychological scientists from the University of British Columbia and a researcher from the Organization for Economic Cooperation and Development in France tested two groups of newborns, one of which only heard English in the womb and the others who heard English and Tagalog, which is spoken in the Philippines.

DARPA Wants To Build The Ultimate Language Traslator

Darpa Looks to Build Real-Life C3P0 -- The Danger Room

Right now, troops trying to listen in on enemy chatter rely on a convoluted process. They tune into insurgency radio frequencies, then hand the radio over to local interpreters, who translate the dialogues. It’s a sloppy process, prone to garbled words and missed phrases.

What troops really need is a machine that can pick out voices from the noise, understand and translate all kinds of different languages, and then identify the voice from a hit list of “wanted speakers.” In other words, a real-life version of Star Wars protocol droid C3PO, fluent “in over 6 million forms of communication.”

Northern Hemisphere Snow Extent Second Highest On Record

Source : Rutgers University Global Snow Lab

From Watts Up With That?:

According to Rutgers University Global Snow Lab, last week’s Northern Hemisphere winter snow extent was the second highest on record, at 52,166,840 km2. This was only topped by the second week in February, 1978 at 53,647,305 km2. Rutgers has kept records continuously for the last 2,227 weeks, so being #2 is quite an accomplishment.

United States' Drought Has 'Extraordinary' Reversal

From USA Today:

What a difference a rain makes. The nationwide drought that had farmers, communities and entire states fighting to conserve water has reversed in the most dramatic turnaround since federal scientists began keeping records.

More than 92% of the country is drought-free — the nation's best showing since 1999.

"The lack of drought is extraordinary," said Douglas Le Comte, a meteorologist with the federal Climate Prediction Center.

Wind Turbines Make Their Own Clouds (Another Reason You Might Not Want One On Your Doorstep)

The wind farm at Scroby Sands off East Anglia is shrouded in sea fog caused by its spinning blades

From The Daily Mail:

An offshore wind farm has been creating its own 'micro-climate' by stirring up air to create low-level clouds around its giant, spinning blades.

These stunning pictures show the mist caused by the spinning 40 metre blades of the turbines whipping up moisture from the surface of the sea at Scroby Sands near Great Yarmouth, Norfolk.

Holidaymakers often walk around in bright sunshine on the beach while watching the mist envelop the £75m wind farm less than two miles offshore.

Medical Potential Of IPS Stem Cells Exaggerated Says World Authority

IPS cells were named the breakthrough of 2008

From Times Online:

The medical potential of reprogrammed stem cells that do not require the destruction of embryos has been exaggerated, according to the head of one of the world’s leading regenerative medicine companies.

Thomas Okarma, the chief executive of Geron Corporation, told The Times that while so-called induced pluripotent stem (IPS) cells will be extremely useful in research, they are unlikely to be suitable for transplanting to patients to treat disease.

From The Independent:

Secrets of Egyptian boy king's lineage and cause of death unearthed.

His autopsy took some time to complete – more than 3,000 years, in fact – but scientists now believe they know why the Egyptian boy king Tutankhamun died, as well as who his parents and grandmother were.

After conducting an extensive analysis of the ancient pharaoh's DNA, which they gathered from his mummified remains, the researchers concluded that a combination of malaria and bone abnormalities contributed to his premature death at the age of 19 in 1324 BC.
