"As we get more data, we can fit more model. But at some point we become so overwhelmed by data that, for computational reasons, we can barely do anything at all. Thus, the curve above could be thought of as the product of two curves: a steadily increasing curve showing the statistical ability to fit more complex models with more data, and a steadily decreasing curve showing the computational feasibility of doing so."

"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."

Note: this would make a good blog post Minimalist posters explain complex philosophical concepts with basic shapes When it comes to explaining philosophy, sometimes less is more - and we think this arresting collection of minimalist posters encompasses that idea perfectly. The illustrations you see featured below are from a a series entitled "Philographics," and were created by London-based graphic designer Genís Carreras. Using basic colors, simple geometric design, and concise definitions, Carreras manages to cram impressive amounts of information - on philosophical doctrines as diverse as hedonism, determinism, and existentialism - into a surprisingly simple and accessible package. We've included a sample of the collection below, but you'll find the series in its entirety, along with plenty more examples of Carreras' work, over on his website. The posters are also available for purchase via society6.

A report in the New Journal of Physics shows how the quest for an invisibility cloak is leading to cleverer ways to use and manipulate light. The trick could aid the analysis of complex samples or even communications.

There's a new adventure video capture company in town, and both Zeyez and GoPro would have good reason to be afraid. You may not have heard of Pivothead -- the company has had a remarkably quiet push to market over the last few months -- but the video recording eyewear startup could very well become a household name after its first products hit the market this April for $349. Aurora, Durango, Moab and Recon may offer distinct exterior designs, but they're virtually identical under the hood. Each model includes an eight-megapixel Sony sensor (that reportedly captures higher quality images than the iPhone 4S cam), a four-element glass lens, 8GB of built-in storage, a 440mAh battery (with about an hour of shooting time) and three video modes: 1080/30p, 720/60p and 720/30p. We had a chance to go hands-on with Pivothead earlier today, and took the glasses for a spin on the streets of New York City. You'll find that sample video, along with our impressions, just past the break.
