"Researchers in China say that they've successfully managed to test an engine that runs on electricity, requires no propellant and produces no exhaust. It's called the EmDrive, and it's able to convert microwave energy directly into thrust inside a sealed chamber. Oh, it's totally silent and highly efficient, too. If it seems too good to be true, well, you're not the only one who feels that way. But the researchers have a prototype that apparently works, and they've just published a paper detailing it."

Dan Siroker helps companies discover tiny truths, but his story begins with a lie. It was November 2007 and Barack Obama, then a Democratic candidate for president, was at Google's headquarters in Mountain View, California, to speak. Siroker-who today is CEO of the web-testing firm Optimizely, but then was a product manager on Google's browser team-tried to cut the enormous line by sneaking in a back entrance. "I walked up to the security guard and said, 'I have to get to a meeting in there,'" Siroker recalls. There was no meeting, but his bluff got him in.

The centenary of Alan Turing's birth is being greeted by an extraordinary response, not only in mathematical and scientific circles but in a much wider public arena. It marks the awareness that he was one of the 20th century's seminal figures, whose brief life is better appreciated in the 21st century than in his own.

"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 The self-cleansing character of science calls for fraudulent publications to be withdrawn and no longer to proliferate within the literature.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."

"GENEVA - A United Nations expert called Thursday for a global moratorium on the testing, production and use of armed robots that can select and kill targets without human command."

"Businesses invest billions of dollars annually in market research studies developing and testing new ideas by asking consumers questions they simply can't answer. Asking consumers what they want, or why they do what they do, is like asking the political affiliation of a tuna fish sandwich. That's because neuroscience is now telling us that consumers, i.e., humans, make the vast majority of their decisions unconsciously. Steve Jobs didn't believe in market research. When a reporter once asked him how much research he conducted to develop the iPad, he quipped, "None. It isn't the consumers' job to know what they want." And according to some measures, the iPad became the most successful consumer product launch ever and Apple went on to become the most valuable company of all-time."

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.

Gamers angered at the "bleak" ending of Mass Effect 3 have campaigned for an alternate conclusion - and raised more than $70,000 (£44,000) for charity.

In addition to a high-tech grocery cart and an augmented-reality mirror, one of the futuristic projects on display at Microsoft's TechForum event earlier this week was a research project exploring the possibilities for using a transparent LCD display in conjunction with a Kinect sensor to let people interact with virtual objects in a 3D space by moving their hands around behind the screen.

Summary:  Sharks often use the "bump and bite" attack:  The shark tests its prey by repeatedly bumping it.  If the prey gives no dangerous response, the shark begins its attack - biting the prey repeatedly and viciously.  It works for sharks, as it has worked for our leaders.  Now the bumping phase ends and the attack begins. Attorney General Eric Holder explains the new order.

Reproducibility is a key part of science, even though almost nobody does the same experiment twice. A lab will generally repeat an experiment several times and look for results before they get published. But, once that paper is published, people tend to look for reproducibility in other ways, testing the consequences of a finding, extending it to new contexts or different populations. Almost nobody goes back and repeats something that's already been published, though. But maybe they should. At least that's the thinking behind a new effort called the Reproducibility Initiative, a project hosted by the Science Exchange and supported by Nature, PLoS, and the Rockefeller University Press.

Technology is a lovely thing, but sometimes it scares the bejeezus out of us. This working 3D-printed gun is one such case. Gun enthusiast "HaveBlue" has documented in a blog post (via the AR15 forums) the process of what appears to be the first test firing of a firearm made with a 3D printer.

Let's say you have two hosts, somewhere out on the Internet: Maybe dedicated servers, maybe Amazon EC2 or Rackspace instances, maybe a mix of the above. Now assume it's your job to provide secure, encrypted connectivity between two services running on those hosts. If those services do not use an encrypted protocol by themselves - such as non-SSL capable SMTP mail servers - then the standard answer has always been: "Use stunnel or OpenVPN!". While both of those are good, cross-platform solutions which can forward unsecure traffic over an encrypted tunnel, I believe that they come not only with administrative overhead, but also introduce a significant performance hit. I believe that there are now solutions that are easier to use, more flexible and most importantly, deliver much better performance. In this article, I will compare stunnel performance  characteristics with vCider's virtual private network solution (sign up for use with up to 8 nodes is free). You will see that vCider not only offers more flexibility and is easier to use, but also provides significantly better network performance and reduced CPU load. For my test, I have created two Ubuntu instances on Rackspace. Please note that both stunnel as well as vCider can work across network and cloud provider boundaries.

From disrupting the peer-reviewed journal publishing tradition to utilizing a dispersed model to test code, the academy has been trying out new ways of innovating an overburdened scholarly apparatus using technology. One of the latest areas to see this sort of experimentation is that of IP, or intellectual property. Marblar, a startup launched by three British PhD students, is hoping to successfully crowdsource the resurrection of "dormant" IP, to flatten and widen the process of tech transfer. A major British venture capital firm, IP Group, has invested about $600,000 in the startup.

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.

Can a person's Facebook profile reveal what kind of employee he or she might be? The answer is yes, and with unnerving accuracy, according to a new paper published in the Journal of Applied Social Psychology.
