Amazon elbows past Samsung for No. 2 tablet spot in Q4, according to IHS

EDIT Amazon elbows its way past Samsung for No. 2 tablet spot
Amazon had some serious trombone action going on last year -- what with all the horn tooting it did about Kindle Fire demand. Turns out Amazon was on to something, as the company has apparently grabbed the No. 2 spot from Samsung for tablet sales in the last quarter, according to research firm IHS iSuppli. Based on its numbers, Amazon sold 3.89 million tablets during the fourth quarter, eclipsing Samsung's 2.14 million units. The numbers equal a 14 percent share of the tablet market for Amazon while Samsung grabbed an 8 percent share, down from 11 percent in the third quarter. The brisk sales came at a price for Amazon, which saw fourth-quarter profits drop since it sold Kindle Fire tablets at a loss. Amazon's tablet sales also were still below the 15.4 million iPads sold by Apple for the period. All the competition is apparently taking a bite out of Apple's market share, however, which fell to 62 percent in 2011, compared to 87 percent in 2010. Samsung did manage to hold on to the No. 2 spot for the year, but with rumors already swirling about new iPads plus the Galaxy Note 10.1, the tablet wars aren't likely to cool off anytime soon.

Researchers develop better control for DNA-based computations

ScienceDaily (Feb. 17, 2012) ? A North Carolina State University chemist has found a way to give DNA-based computing better control over logic operations. His work could lead to interfacing DNA-based computing with traditional silicon-based computing.

The idea of using DNA molecules -- the material genes are made of -- to perform computations is not new; scientists have been working on it for over a decade. DNA has the ability to store much more data than conventional silicon-based computers, as well as the potential to perform calculations in a biological environment -- inside a live cell, for example. But while the technology holds much promise, it is still limited in terms of the ability to control when and where particular computations occur.

Dr. Alex Deiters, associate professor of chemistry at NC State, developed a method for controlling a logic gate within a DNA-based computing system. Logic gates are the means by which computers "compute," as sets of them are combined in different ways to enable the computer to ultimately perform tasks like addition or subtraction. In DNA computing, these gates are created by combining different strands of DNA, rather than by a series of transistors. The drawback is that DNA computation events normally take place in a test tube, where the sequence of computation events cannot be easily controlled with spatial and temporal resolution. So while DNA logic gates can and do work, no one can tell them when or where to work, making it difficult to create sequences of computational events.

In a paper published in the Journal of the American Chemical Society, Deiters addressed the control problem by making portions of the input strands of DNA logic gates photoactivatable, or controllable by ultraviolet (UV) light. The process is known as photocaging. Deiters successfully photocaged several different nucleotides on a DNA logic gate known as an AND gate. When UV light was applied to the gate, it was activated and completed its computational event, showing that photoactivatable logic gates offer an effective solution to the "when and where" issues of DNA-based logic gate control.

Deiters hopes that using light to control DNA logic gates will give researchers the ability not only to create more complicated, sequential DNA computations, but also to create interfaces between silicon and DNA-based computers.

"Since the DNA gates are activated by light, it should be possible to trigger a DNA computation event by converting electrical impulses from a silicon-based computer into light, allowing the interaction of electrical circuits and biological systems," Deiters says. "Being able to control these DNA events both temporally and spatially gives us a variety of new ways to program DNA computers."

(AP) ? He's considered to be one of the greatest scientists of all time. But Sir Isaac Newton was also an influential theologian who applied a scientific approach to the study of scripture, Hebrew and Jewish mysticism.

Now Israel's national library, an unlikely owner of a vast trove of Newton's writings, has digitized his theological collection ? some 7,500 pages in Newton's own handwriting ? and put it online. Among the yellowed texts are Newton's famous prediction of the apocalypse in 2060.

Newton revolutionized physics, mathematics and astronomy in the 17th and 18th century, laying the foundations for most of classical mechanics ? with the principal of universal gravitation and the three laws of motion bearing his name.

However, the curator of Israel's national library's humanities collection said Newton was also a devout Christian who dealt far more in theology than he did in physics and believed that scripture provided a "code" to the natural world.

"Today, we tend to make a distinction between science and faith, but to Newton it was all part of the same world," said Milka Levy-Rubin. "He believed that careful study of holy texts was a type of science, that if analyzed correctly could predict what was to come."

So he learned how to read Hebrew, scrolled through the Bible and delved into the study of Jewish philosophy, the mysticism of Kabbalah and the Talmud ? a compendium of Jewish oral law and stories about 1,500 years old.

For instance, Newton based his calculation on the end of days on information gleaned from the Book of Daniel, which projected the apocalypse 1,260 years later. Newton figured that this count began from the crowning of Charlemagne as Roman emperor in the year 800.

The papers cover topics such as interpretations of the Bible, theology, the history of ancient cultures, the Tabernacle and the Jewish Temple.

The collection also contains maps that Newton sketched to assist him in his calculations and his attempts to reveal the secret knowledge he believed was encrypted within.

He attempted to project what the end of days would look like, and the role Jews would play when it happened. Newton's objective curiosity in Judaism and the Holy Land contrasted with the anti-Jewish sentiment expressed by many leading Christian scholars of the era, Levy-Rubin said.

"He took a great interest in the Jews, and we found no negative expressions toward Jews in his writing," said Levy-Rubin. "He said the Jews would ultimately return to their land."

How his massive collection of work ended up in the Jewish state seems mystical in its own right.

Years after Newton's death in 1727, his descendants gave his scientific manuscripts to his alma mater, the University of Cambridge.

But the university rejected his nonscientific papers, so the family auctioned them off at Sotheby's in London in 1936. As chance would have it, London's other main auction house ? Christie's ? was selling a collection of Impressionist art the same day that attracted far more attention.

Only two serious bidders arrived for the Newton collection that day. The first was renowned British economist John Maynard Keynes, who bought Newton's alchemy manuscripts. The second was Abraham Shalom Yahuda ? a Jewish Oriental Studies scholar ? who got Newton's theological writings.

Yahuda's collection was bequeathed to the National Library of Israel in 1969, years after his death. In 2007, the library exhibited the papers for the first time and now they are available for all to see online.

The collection contains pages after pages of Newton's flowing cursive handwriting on fraying parchment in 18th-century English, with words like "similitudes," ''prophetique" and "Whence."

Two print versions in modern typeface are also available for easier reading: A "diplomatic" one that includes changes and corrections Newton made in the original manuscript, and a "clean" version that incorporates the corrections.

All of the papers are linked to the Newton Project, which is hosted by the University of Sussex and includes other collections of Newton's writings.

The Israeli library says the manuscripts help illuminate Newton's science and well as his persona.

"As far as Newton was concerned, his approach was that history was as much a science as physics. His world view was that his 'lab' for understanding history was the holy books," said Levy-Rubin. "His faith was no less important to him than his science."
