Unknown Mathematician Proves Elusive Property of Prime Numbers. On April 17, a paper arrived in the inbox of Annals of Mathematics, one of the discipline’s preeminent journals. Written by a mathematician virtually unknown to the experts in his field — a 50-something lecturer at the University of New Hampshire named Yitang Zhang — the paper claimed to have taken a huge step forward in understanding one of mathematics’ oldest problems, the twin primes conjecture. Editors of prominent mathematics journals are used to fielding grandiose claims from obscure authors, but this paper was different.
Written with crystalline clarity and a total command of the topic’s current state of the art, it was evidently a serious piece of work, and the Annals editors decided to put it on the fast track. Just three weeks later — a blink of an eye compared to the usual pace of mathematics journals — Zhang received the referee report on his paper. Daft Punk: the midas touch. It is a peculiar experience meeting the most famous faceless musicians in the world. Daft Punk are certainly well known. Eight years after their last album, their influence can be felt throughout dance music and beyond.
Their fourth release, Random Access Memories , is the most hysterically anticipated record in years: every tidbit disseminated online over the past two months has been scrutinised like a fragment of the true cross. At a point in their career when most bands are on a downward slope, Daft Punk have just celebrated their first number one single, "Get Lucky", and are somehow bigger than ever. "They're two of the greatest innovators in popular music and we're as excited to hear what they are doing as we are about David Bowie," says Chris Price, music editor of industry trade magazine Record of the Day .

I created my own isomorphic version (meaning that I kept the same topology) trying to balance surface areas, so each piece has a similar visual importance. Inspired by Newton's theories on light and color spectrum I decided to use colors rather than numbers or letters to identify each basic set, though I didn't use the same colors Newton did; mine are equidistant in the hue circle.
I named the colors using this table, in each case identifying the closest and borrowing his name. Yes, it's a Mandala, and it has two different sides (drag it to check!)

Because, this father found, it actually increased family harmony. (First published in Disney’s Wondertime Magazine. The article was nominated for a 2007 National Magazine Award.) Those of you who don’t have perfect children will find this familiar: Just as I was withdrawing money in a bank lobby, my 5-year-old daughter chose to throw a temper tantrum, screaming and writhing on the floor while a couple of elderly ladies looked on in disgust. (Their children, apparently, had been perfect.)
Biologist and computer scientist discover the 'anternet' A collaboration between a Stanford ant biologist and a computer scientist has revealed that the behavior of harvester ants as they forage for food mirrors the protocols that control traffic on the Internet.
On the surface, ants and the Internet don't seem to have much in common. But two Stanford researchers have discovered that a species of harvester ants determine how many foragers to send out of the nest in much the same way that Internet protocols discover how much bandwidth is available for the transfer of data. The researchers are calling it the "anternet. " Deborah Gordon, a biology professor at Stanford, has been studying ants for more than 20 years. When she figured out how the harvester ant colonies she had been observing in Arizona decided when to send out more ants to get food, she called across campus to Balaji Prabhakar, a professor of computer science at Stanford and an expert on how files are transferred on a computer network.
Harvester ants. Animals conscious say leading neuroscientists. A group of leading neuroscientists has used a conference at Cambridge University to make an official declaration recognising consciousness in animals.
The declaration was made at the Francis Crick Memorial Conference and signed by some of the leading lights in consciousness research, including Christof Koch and David Edelman. You can read the full text as a pdf file, however, the main part of the declaration reads: We declare the following: “The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness. Tweets vs. Likes: What gets shared on Twitter vs. Facebook?
It always strikes me as curious that some posts get a lot of love on Twitter, while others get many more shares on Facebook: What accounts for this difference?
Some of it is surely site-dependent: maybe one blogger has a Facebook page but not a Twitter account, while another has these roles reversed. But even on sites maintained by a single author, tweet-to-likes ratios can vary widely from post to post. So what kinds of articles tend to be more popular on Twitter, and which spread more easily on Facebook?

Songs are represented as tree-like structures of code. Each generation starts with 100 songs; however, for clarity, it only follows one-fifth of them. Twenty songs are randomly presented to listeners for rating, and the remaining 80 survive until the next generation; thus, at any time, the population contains songs of varying age. Of the 20 rated songs, the 10 best reproduce and the 10 worst die.
Reproductives are paired and produce four progeny to replace themselves and the dead in the next generation. The Scale of the Universe 2. Brain Workshop - a Dual N-Back game.

Update 11:15 am PDT: The headline of this post has been changed to reflect that we have not confirmed Smeets’ claim. Editor’s note (March 21, 8:15 am PDT): The authenticity of this video has been questioned (Gizmodo, The Register), but Wired’s preliminary analysis by physicist Rhett Allain found nothing in the video that indicates it must be a fake.

Dear Human, Peter Diamandis interviewed by Jeff Walker about his book "Abundance" Spider silk spun into violin strings. 4 March 2012Last updated at 19:59 ET By Jason Palmer Science and technology reporter, BBC News More than 300 spiders were used to generate the thousands of strands of silk making up each string A Japanese researcher has used thousands of strands of spider silk to spin a set of violin strings. The strings are said to have a "soft and profound timbre" relative to traditional gut or steel strings. That may arise from the way the strings are twisted, resulting in a "packing structure" that leaves practically no space between any of the strands. The strings will be described in a forthcoming edition of the journal Physical Review Letters.
