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.

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.

If you're taking a break from work to read this article, I've got one question for you: Are you crazy? I know you think no one will notice, and I know that everyone else does it. Perhaps your boss even approves of your Web surfing; maybe she's one of those new-age managers who believes the studies showing that short breaks improve workers' focus. But those studies shouldn't make you feel good about yourself. The fact that you need regular breaks only highlights how flawed you are as a worker. I don't mean to offend. It's just that I've seen your competition. Let me tell you: You are in peril.

Scaling College Composition by AUDREY WATTERS on 22 APR, 2012 I've been thinking a lot this week about two seemingly unrelated news items. The first, the research by David Shermis and Ben Hamner that found that automated essay grading software performs comparably to human graders. (See the Inside Higher Ed story.) The second, the official unveiling of Coursera, the latest online learning startup to spin out of Stanford, that promises to offer a full course catalog, including many classes in the humanities. (Here's my write-up of the news). The connection: scaling how we assess student writing.

As organizations like Code for America encourage government transparency and the concept of Open Data at multiple levels of government in the US, I think it's useful for us to take a look at how Open Data is handled in other countries. Given my non-existent skills in other languages and my distrust of Google Translate, I'll focus on English-speaking countries first.

There's been a movement afoot to boycott Elsevier journals. It's started over in the mathematics community, led by Timothy Gowers, a serious mathematician indeed. The objections to Elsevier are the ones you'd think: high prices, unsplittable bundles of journal subscriptions for institutions, and their strong support for legislation like the Research Works Act.

There's no doubting the cloud invasion. But the research firm Gartner believes the personal cloud will replace the PC as the center of our digital lives sooner than you might think: 2014. "Major trends in client computing have shifted the market away from a focus on personal computers to a broader device perspective that includes smartphones, tablets and other consumer devices," Steve Kleynhans, research vice president at Gartner, said in a statement on Monday. "Emerging cloud services will become the glue that connects the web of devices that users choose to access during the different aspects of their daily life."

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.

The Sith Lord Darth Vader, of Star Wars fame, often gets a bad rap, particularly in what we all think of as his 'dark years.' From a certain perspective his mass murder, brutal oppression, and frequent deception to serve his own ends makes him seem like a pretty bad guy. But if you look past all that to his action, you will find a very capable and effective project manager.

Ever since his grad student days at Hebrew University of Jerusalem, Amir Ronen, now a scientist at IBM Research -  Haifa, has been thinking about the intersection of game theory and computer science. In fact, he's one of the leaders in a sub-discipline, called algorithmic game theory, which lies at the intersection of the two fields.

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

For the first time, the international organization has set a date for the moment when the "Age of America" will end and the U.S. economy will be overtaken by that of China And it's a lot closer than you may think.

Robert Harvey asks: Occasionally I see questions about edge cases on Stack Overflow that are easily answered by the likes of Jon Skeet or Eric Lippert-experts who demonstrate a deep knowledge of a particular language and its many intricacies. Here's an example of this from Lippert's MSDN blog: You might think that in order to use a foreach loop, the collection you are iterating over must implement IEnumerable or IEnumerable. But as it turns out, that is not actually a requirement. What is required is that the type of the collection must have a public method called GetEnumerator, and that must return some type that has a public property getter called Current and a public method MoveNext that returns a bool. If the compiler can determine that all of those requirements are met then the code is generated to use those methods. Only if those requirements are not met do we check to see if the object implements IEnumerable or IEnumerable. This is cool stuff to know. I can understand why Eric knows this; he's on the compiler team, so it's explicitly in his job description to know. But how do mere mortals, those of us on the outside, find out about stuff like this?

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.

The last time we ran into Ben Heck, the tinkerer extraordinaire was waxing poetic at Maker Faire about the Raspberry Pi and cheese curds. One more thing he also talked about, however, was his latest 3D printer project, which he now explains in greater detail in the latest episode of the Ben Heck Show. Improvements made to the device include use of a Birdstruder for easier access to the filament and the ability to print off an SD card if you don't have a computer handy. The 3D printer also sports an expanded 200-square-millimeter print area with a solid copper cover for added sturdiness and accuracy. As usual, size matters for Mr. Heckendorn so the device got a boost in portability, now neatly folding James Bond-like into a briefcase that measures 18 x 14 x 4.2 inches. Interested in a briefcase printer of your own? Well, Heckendorn mentioned during the Maker Faire interview that he's already working on an improved version and thinking about putting it up on Kickstarter so hope springs eternal. In the meantime, you can glean more details about the device by checking out the video after the break.

As I said in my recent review, I generally had a blast making my way through Uncharted: Golden Abyss on the PlayStation Vita. Despite some annoyances with the system's touch-screen and tilt-based controls, I had a good time working through the shooting and climbing sections and being rewarded with some well-acted witty banter in the cut scenes. But despite my overall enjoyment, there was still one point in the game where I was so frustrated I was ready to turn it off and never return. And while this frustration was probably at least as much my fault as the game's, I still think it would have been nice, and much less frustrating, if the game had offered just a little help getting me past that point.
