In 1991, when I was a staff writer for Scientific American, I wrote a letter to Thomas Kuhn, then at MIT. I said I wanted to profile him for Scientific American and "tell readers how you developed your views of the process of science." When he didn't respond, I called. Kuhn was reluctant to do the interview. He distrusted journalists, and he was still peeved by an old Scientific American review of his 1962 book The Structure of Scientific Revolutions. When I persisted, Kuhn asked to see other profiles I had done, and I mailed him pieces on his MIT colleagues Claude Shannon and Noam Chomsky.

In a stunning move, on March 16, 2012, Barack Obama signed an Executive Order stating that the President and his specifically designated Secretaries now have the authority to commandeer all domestic U.S. resources including food and water. The EO also states that the President and his Secretaries have the authority to seize all transportation, energy, and infrastructure inside the United States as well as forcibly induct/draft American citizens into the military. The EO also contains a vague reference in regards to harnessing American citizens to fulfill "labor requirements" for the purposes of national defense.

"Someone points me to this report from Tilburg University on disgraced psychology researcher Diederik Stapel. The reports includes bits like this: When the fraud was first discovered, limiting the harm it caused for the victims was a matter of urgency. This was particularly the case for Mr Stapel's former PhD students and postdoctoral researchers . . . However, the Committees were of the opinion that the main bulk of the work had not yet even started. . . . Journal publications can often leave traces that reach far into and even beyond scientific disciplines. The self-cleansing character of science calls for fraudulent publications to be withdrawn and no longer to proliferate within the literature. In addition, based on their initial impressions, the Committees believed that there were other serious issues within Mr Stapel's publications . . . This brought into the spotlight a research culture in which this sloppy science, alongside out-and-out fraud, was able to remain undetected for so long. . . . The scientific literature must be cleansed of everything that is fraudulent, especially if it involves the work of a leading academic. Sounds familiar? I think it also applies to recipients of the Founders Award from the American Statistical Association. There's more: The most important reason for seeking completeness in cleansing the scientific record is that science itself has a particular claim to the finding of truth. This is a cumulative process, characterized in empirical science, and especially in psychology, as an empirical cycle, a continuous process of alternating between the development of theories and empirical testing. . . . My first reaction was that all seems like overkill given how obvious the fraud is, but given what happened with comparable cases in the U.S., I suppose this "Powell doctrine" approach (overwhelming force) is probably the best way to go."

VANCOUVER, British Columbia - Our digital age is all about bits, those precise ones and zeros that are the stuff of modern computer code. But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between - all at the same time.

At least since the followers of Ned Ludd smashed mechanized looms in 1811, workers have worried about automation destroying jobs. Economists have reassured them that new jobs would be created even as old ones were eliminated. For over 200 years, the economists were right. Despite massive automation of millions of jobs, more Americans had jobs at the end of each decade up through the end of the 20th century. However, this empirical fact conceals a dirty secret. There is no economic law that says that everyone, or even most people, automatically benefit from technological progress.

This honor goes to Dr. Ronald Breslow of Columbia University, who ended his recent paper "Evidence for the Likely Origin of Homochirality in Amino Acids, Sugars, and Nucleosides on Prebiotic Earth" in the Journal of the American Chemical Society with an ominous editorial. After an otherwise technical paper about the prehistoric origins of amino acids, the conclusion takes a turn for the extremely sinister. Emphasis is ours:

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.

DARPA is unveiling a portable laser weapons system, HELLADS, which seems like something out of a sci-fi movie. The new laser application, created by General Atomics Aeronautical Systems with a custom power system from Saft Batteries, will help change the way the American military fights future wars. Current military laser systems are bulky contraptions which are mainly the size of a passenger jet, while the proposed DARPA weapon can fit on the back of a flatbed truck. The 150-kilowatt, solid state laser weapon is strong enough to take down drones or other aerial targets; a prototype is expected to be available by the end of 2012.

Conservatives' trust of science has gradually decreased over the past 40 years, beginning perhaps when empirical research was increasingly used to justify government regulations, according to a new academic analysis.

The American Journalism Review has just published a searing condemnation by Washington Post contributor Paul Farhi of the state of education journalism, much of which, it contends, reinforces a narrative that the U.S. school system is failing -- a narrative supported by "self-styled education reformers," but refuted by the experiences of many parents asked to rate their local schools. I've railed against this before in the context of tech blogs' treatment of education, and while the AJR piece doesn't address technology specifically, I would argue that the narratives of failing schools certainly fuel much of the growing business of ed-tech.

The eminent British scientist James Lovelock, back in the 1970s, formulated his theory of Gaia, which held that the Earth was a kind of super organism. It had a self-regulating quality that would keep everything within that narrow band that made life possible. If things got too warm or too cold-if sunlight varied, or volcanoes caused a fall in temperatures, and so forth-Gaia would eventually compensate. This was a comforting notion. It was also wrong, as Lovelock himself later concluded. "I have to tell you, as members of the Earth's family and an intimate part of it, that you and especially civilization are in grave danger," he wrote in the Independent in 2006.

Caffeine will get you going during the day but could leave you tossing and turning at night  unless you're  a "night owl" to begin with, a new study suggests.

Our personal data is among today's most valuable information currency. It's often hard to determine what part companies own, what part the government owns, and what part, if any, is entirely our own - provided a third party hasn't already sold it to someone else.

As summer blockbuster season kicks into high gear, big-budget action movies like The Avengers, Battleship, and Prometheus remind us that there's one thing that unites Americans: Our shared fear of an alien attack. They also remind us that when the invading space fleet arrives, humanity is not going to surrender without a fight to our intergalactic invaders. Instead, we will band together to fight off their incredibly advanced weaponry with our ... well, with what, exactly? Are we really ready to battle our would-be alien overlords?

The language we use affects the decisions we make, according to a new study. Participants made more rational decisions when money-related choices were posed in a foreign language that they had learned in a classroom setting than when they were asked in a native tongue.

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?

"It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery."

SANTA BARBARA-"Maybe we're just too dumb," Nobel laureate physicist David Gross mused in a lecture at Caltech two weeks ago. When someone of his level wonders whether the unification of physics will always be beyond mortal minds, it gets you worried. Since his lecture, I've been learning about a theory that seems to confirm Gross's worry. It is so ridiculously hard that it could be the subject of an Onion parody. But at the same time, I've been watching how physicists are trying to power through their intimidation, because the theory promises a new way of understanding what space and time really are, at a deep level.

It is rather odd how often I hear the expression paradigm shift during contemporary scientific presentations and seminars. The expression was popularized by Thomas Kuhn's book The Structure of Scientific Revolutions. In that book, Kuhn referred to ground-breaking and revolutionary changes in scientific thought as paradigm shifts, but the expression is so over-used today that even minor discoveries are sometimes marketed as paradigm shifts.

Although there is an urban legend that the world will end this year based on a misinterpretation of the Mayan calendar, some researchers think a 40-year-old computer program that predicts a collapse of socioeconomic order and massive drop in human population in this century may be on target
