"Here's an issue we don't talk about enough. Every year, peer-reviewed research journals publish hundreds of thousands of scientific papers. But every year, several hundred of those are retracted - essentially, unpublished. There's a number of reasons retraction happens. Sometimes, the researchers (or another group of scientists) will notice honest mistakes. Sometimes, other people will prove that the paper's results were totally wrong. And sometimes, scientists misbehave, plagiarizing their own work, plagiarizing others, or engaging in outright fraud. Officially, fraud only accounts for a small proportion of all retractions. But the number of annual retractions is growing, fast. And there's good reason to think that fraud plays a bigger role in science then we like to think. In fact, a study published a couple of weeks ago found that there was misconduct happening in 3/4ths of all retracted papers. Meanwhile, previous research has shown that, while only about .02% of all papers are retracted, 1-2% of scientists admit to having invented, fudged, or manipulated data at least once in their careers."

Android applications downloaded by as many as 185 million users can expose end users' online banking and social networking credentials, e-mail and instant-messaging contents because the programs use inadequate encryption protections, computer scientists have found. The researchers identified 41 applications in Google's Play Market that leaked sensitive data as it traveled between handsets running the Ice Cream Sandwich version of Android and webservers for banks and other online services. By connecting the devices to a local area network that used a variety of well-known exploits, some of them available online, the scientists were able to defeat the secure sockets layer and transport layer security protocols implemented by the apps. Their research paper didn't identify the programs, except to say they have been downloaded from 39.5 million and 185 million times, based on Google statistics.

Can robots work as scientists? At first, this seems like a silly question. Computers are pervasive in science, and if you walk into a large university lab today, there's a good chance you'll find a fully fledged robot working alongside the lab-coat-wearing humans. Robots fill test tubes, make DNA microarrays, participate in archaeological digs, and survey the oceans. There are entire branches of science-climate modeling and genomics, for example-that wouldn't exist without powerful microprocessors. Machines even play an integral part in abstract fields of discovery. In experimental mathematics, humans rely on computers to inspire new lines of thinking and investigate hypotheses. In 1976, mathematicians used computers to prove the four-color theorem, and machines have since been used in several other proofs.

Scientists are pioneering the use of 3D printers to create drugs and other chemicals at the University of Glasgow. Researchers have used a £1,250 system to create a range of organic compounds and inorganic clusters - some of which are used to create cancer treatments. Longer term, the scientists say the process could be used to make customised medicines.

A way to print Radio Frequency Identification (RFID) chips right onto paper has been discovered by a team of scientists from University of Montpellier.

It seems that more and more policy makers, advocacy groups, advertisers and media pundits are making claims based on science: this kind of potion is good for your health, that chemical is bad for the environment, this new technology can reduce crime. How is the public supposed to know what to believe?

I didn't know whether to take my Ph.D. adviser's remark as a compliment. "You don't write like a scientist," he said, handing me back the progress report for a grant that I had written for him. In my dream world, tears would have come to his eyes, and he would have squealed, "You write like a poet!"

We often worry about people who lie awake in the middle of the night - but it could be good for you. Scientists have been saying for 20 years that the eight-hour sleep may be unnatural, and historians increasingly are backing them up.

A new biologic logic gate based on proteins can perform binary calculations, serving as the first "cellular calculator," researchers say. Various combinations of components can be arranged into circuit elements, leading to specific metabolic processes inside a cell. The setup can answer mathematical questions in a similar fashion to a computer. Bioengineers led by Martin Fussenegger at ETH Zurich built a molecular logic gate using two substances as the transistor elements: the molecule phloretin, which is used to activate nerve fibers and comes from apples, and the widely used antibiotic erythromycin. The substances work as Boolean switches.

When Jonathan Goldman arrived for work in June 2006 at LinkedIn, the business networking site, the place still felt like a start-up. The company had just under 8 million accounts, and the number was growing quickly as existing members invited their friends and colleagues to join. But users weren't seeking out connections with the people who were already on the site at the rate executives had expected. Something was apparently missing in the social experience. As one LinkedIn manager put it, "It was like arriving at a conference reception and realizing you don't know anyone. So you just stand in the corner sipping your drink-and you probably leave early."

Could computers become cleverer than humans and take over the world? Or is that just the stuff of science fiction? Philosophers and scientists at Britain's Cambridge University think the question deserves serious study. A proposed Center for the Study of Existential Risk will bring together experts to consider the ways in which super intelligent technology, including artificial intelligence, could "threaten our own existence," the institution said Sunday. "In the case of artificial intelligence, it seems a reasonable prediction that some time in this or the next century intelligence will escape from the constraints of biology," Cambridge philosophy professor Huw Price said.

""MY, WHAT a big mouth you have, Grandma," says Little Red Riding Hood, with just a hint of suspicion. The wolf sneezes. "Bless you," says the little girl. Sound odd? That's because this snippet of Little Red Riding Hood was written not by a person but by a piece of software called Xapagy. It may not seem like much, but it demonstrates a first step towards computers that can invent stories. It also signals a new approach to designing a more human-like artificial intelligence."

"The global pattern of e-mail communication reflects the cultural fault lines thought to determine future conflict, say computational social scientists."

Synthesis is a think-tank devoted to using the emerging paradigm of complex networks in the social sciences to tackle social and public policy concerns. Over the past 20 years or so, social scientists have increasingly made use of advances in the natural sciences to make better sense of social systems. Fields such as network theory, non-linear mathematics and systems theory, which we refer to as the study of complex networks, give us much greater insights that help us make sense of social systems. Armed with a greater understanding, this collection of paradigm-changing toolboxes can help us to make better policy decisions, in the public, private, and "third" sectors.

Scientists at The Scripps Research Institute in California and the Technion - Israel Institute of Technology - have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips.

I've visited Singapore a few times in recent years and been impressed with its wealth and modernity. I was also quite aware of its world-leading programs in mathematics education and naturally noted that one of the candidates for president was Tony Tan, who has a Ph.D. in applied mathematics. Tan won the very close election and joined the government of Prime Minister Lee Hsien Loong, who also has a degree in mathematics.

If the Space Race characterized the twentieth century, it's possible the Teleportation Race may characterize the twenty-first. Scientists all over the world are trying to perfect teleportation techniques, for a wide variety of applications including communications technology. (Sorry, this isn't the kind of teleportation that involves sending you through a wormhole to the other side of the galaxy.) And now, a group of researchers led by Juan Yin at the University of Science and Technology of China in Shanghai have published a paper on ArXiv describing how they teleported entangled photons over a distance of 97 kilometres across a lake in China.

Ever since his grad student days at Hebrew University of Jerusalem, Amir Ronen, now a scientist at IBM Research -  Haifa, has been thinking about the intersection of game theory and computer science. In fact, he's one of the leaders in a sub-discipline, called algorithmic game theory, which lies at the intersection of the two fields.
