"A Swiss study appears to have uncovered what anti-capitalist activists have been claiming for years -- that the global economy is controlled by a small group of deeply interconnected entities. But don't grab a pitchfork and head to the nearest Occupy protest just yet. Systems researchers say this isn't the result of an Illuminati-type global conspiracy, but rather a natural force to be expected. "Such structures are common in nature," complex systems expert George Sudihara told NewScientist."

"Are more people doing wrong or are more people speaking up? Retractions of scientific papers have increased about tenfold during the past decade, with many studies crumbling in cases of high-profile research misconduct that ranges from plagiarism to image manipulation to outright data fabrication. When worries about somebody's work reach a critical point, it falls to a peer, supervisor, junior partner or uninvolved bystander to decide whether to keep mum or step up and blow the whistle. Doing the latter comes at significant risk, and the path is rarely simple. Some make their case and move on; others never give up. And in what seems to be a growing trend, anonymous watchdogs are airing their concerns through e-mail and public forums. Here, Nature profiles three markedly different stories of individuals who acted on their suspicions. Successful or otherwise, each case offers lessons for would-be tipsters."

Researchers have remotely activated genes inside living animals, a proof of concept that could one day lead to medical procedures in which patients' genes are triggered on demand. The work, in which a team used radio waves to switch on engineered insulin-producing genes in mice, is published today in Science1.

"A brain-to-brain interface (BTBI) enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats. In this BTBI, an "encoder" rat performed sensorimotor tasks that required it to select from two choices of tactile or visual stimuli. While the encoder rat performed the task, samples of its cortical activity were transmitted to matching cortical areas of a "decoder" rat using intracortical microstimulation (ICMS). The decoder rat learned to make similar behavioral selections, guided solely by the information provided by the encoder rat's brain. These results demonstrated that a complex system was formed by coupling the animals' brains, suggesting that BTBIs can enable dyads or networks of animal's brains to exchange, process, and store information and, hence, serve as the basis for studies of novel types of social interaction and for biological computing devices."

While the brightest minds of Silicon Valley are "disrupting" whatever industry is too crippled to fend off their advances, something odd is happening to our language. Old, trusted words no longer mean what they used to mean; often, they don't mean anything at all. Our language, much like everything these days, has been hacked. Fuzzy, contentious, and complex ideas have been stripped of their subversive connotations and replaced by cleaner, shinier, and emptier alternatives; long-running debates about politics, rights, and freedoms have been recast in the seemingly natural language of economics, innovation, and efficiency. Complexity, as it turns out, is not particularly viral.

"It's got to be one of the coolest names ever for a group: The Kansas Anti Zombie Militia. But the group is real and its members are pretty serious about it. Once the Zombie Apocalypse hits, they'll be ready for it and they want you to be too. "Can a natural person change into this monster that many fear?" Alfredo Carbajal, the militia's main spokesman, said in an interview. "The possibilities are yes, it can happen. We have seen incidents that are very close to it, and we are thinking it is more possible than people think.""

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.

People sometimes worry about the Singularity [Vinge, 1993; Kurzweil, 2005], or about the world being taken over by artificially intelligent robots. I believe the risks of these are very small. However, few people recognize that we already share our world with artificial creatures that participate as intelligent agents in our society: corporations. Our planet is inhabited by two distinct kinds of intelligent beings --- individual humans and corporate entities --- whose natures and interests are intimately linked. To co-exist well, we need to find ways to define the rights and responsibilities of both individual humans and corporate entities, and to find ways to ensure that corporate entities behave as responsible members of society.

In a controversial paper in Nature Physics, theorists claim they can prove that wavefunctions - the entity that determines the probability of different outcomes of measurements on quantum-mechanical particles - are real states.

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.

Nano-cargo jet rockets were useful tasks in the body can perform. Packets deliver drugs or substances to signal tumor. Science fiction? Nope, not anymore. Nature chemistry published in February a paper of Nijmegen chemists which they explain how they make a nano rocket. "We think this is the first real nanomotor," says lead author Daniela Wilson.

One of the most beautiful aspects of science is that while there is so much we can see and smell and feel around us, there's an inconceivably large universe around us full of things we can't directly observe. The Tricorder project aims to develop handheld devices that can sense a diverse array of phenomena that we can't normally see, and intuitively visualize them so we might see temperature or magnetism or pressure as naturally as we see colour. 

Say goodbye to your mouse and keyboard. Leap represents an entirely new way to interact with your computers. It's more accurate than a mouse, as reliable as a keyboard and more sensitive than a touchscreen.  For the first time, you can control a computer in three dimensions with your natural hand and finger movements. This isn't a game system that roughly maps your hand movements.  The Leap technology is 200 times more accurate than anything else on the market - at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter. This is like day one of the mouse.  Except, no one needs an instruction manual for their hands.

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.

Forgetting that cloak of invisibility - how about a device that hides you in the very fabric of time? New research published in Nature reveals that scientists have successfully hidden an object in both space and time - even if for only for 40 picoseconds. Rather than bending light around the object, their technique creates a temporal hole in light beams where an event can be hidden.
