Comment Power Supply/Small BJT Amplifier (Score 2, Insightful) 364

How about a power supply they can use to charge their small devices? All you need for a basic power supply are a transformer, some diodes, resistors and capacitors. Or a small voltage divider bias BJT amplifier? a couple capacitors, an NPN transistor, and some resistors. Could be used to amplify music coming from an iPod and show the principals of amplification.

Scientists Discover Proteins Controlling Evolution 436

Khemisty writes "Evolutionary changes are supposed to take place gradually and randomly, under pressure from natural selection. But a team of Princeton scientists investigating a group of proteins that help cells burn energy stumbled across evidence that this is not how evolution works. In fact, their discovery could revolutionize the way we understand evolutionary processes. They have evidence that organisms actually have the ability to control their own evolution."

Submission + - What Programming Languages Should You Know?

nitsudima writes: David Chisnall posits that the more programming languages you know, the better. The point is not to stuff your head with language rules. Rather, he explains how being able to read multiple languages, even if you never code in them, can help you to select the best possible tool for each coding need — and understand the limitations of the tools you're using.

Submission + - MIT's new bedside diagnostics tools

Roland Piquepaille writes: "Massachusetts Institute of Technology (MIT) chemists have developed a high-throughput and inexpensive method for the multiplexed detection of biomolecules by using multifunctional particles. This method could be used to screen for millions of different biomolecules and lead to new and low-cost clinical bedside diagnostics: no more need to wait a day or more before a lab analysis. The particles developed at MIT contain a barcoded ID and one or more probe regions that turn fluorescent when they detect specific targets in a test sample. The researchers think that this method, based on highly customizable particles, could also be used for drug discovery or genetic profiling. Read more for additional references and a picture of a multiplexed analysis using single-probe encoded particles."

Submission + - New Wii Dev Tools in the Making

Ambrose writes: "Looks like Nintendo are finally supporting Third-Party developers. From an article at The Wii Gamers, a new development application called NintendoWare is being developed for Wii Developers. NintendoWare emulates Wii hardware on a PC so that developers can sample parts of their games without having to load it to a Wii dev machine. The motion recognition could also see an upgrade, with a new predictive input tool that uses prior movement to predict your next motion, and a text-to-speech tool is also in the works."

Submission + - The Deal Steve Jobs Couldn't Refuse

Government Drone writes: "Remember the 1997 deal in which Microsoft bought $150 million in non-voting Apple stock? According to this story in InformationWeek, it wasn't done all out of the goodness of Bill Gates' heart:

Weeks prior to bailing out a struggling Apple Computer by purchasing $150 million of its stock, Microsoft officials threatened to cut development of a key product for the Macintosh in order to coerce its rival to make the deal, according to an e-mail unearthed during a recent court hearing.

The original text of the E-mail is here, which mentions a threat to pull the plug on Office for Mac, but argues against it for a variety of reasons. An interesting backend view of what was happening in Apple's darkest days."

Parallax Blue writes: CNET News is running a story on a brain/computer interface system made by Emotiv Systems. It can be used to pick up on thoughts, facial expressions, and emotions within the brain, wirelessly relaying them to a game console or PC. Uses in other industries are planned, including medicine, security, market research, and interactive television.

Submission + - Verizon Fails 3rd Grade Math - Over and Over

stdio9 writes: "One man's struggle to re-educate Verizon employees about 3rd grade mathematics fails, with recorded audio. Hey Verizon: If the customer service manager is making $100k a year, you have a great opportunity here. Rather than paying $0.01335 a second, try paying 0.01335 cents a second. Imagine the cost savings you will turn over for all the phone reps that don't understand the difference. (Assumes a 2080 work hour year, with paid vacation and holidays.)"

Submission + - "Best" 20 Firefox extensions missing a big

PetManimal writes: "Computerworld has an extensive list of the "best" Firefox extensions. It's pretty developer-friedly — including things like Greasemonkey and Firebug — but there are a lot of standard extensions that almost anyone can use that help the browsing experience, like Cooliris Previews. Someone noticed AdBlock didn't make the list, though."

Submission + - Travel Back in Time Not Possible

anthemaniac writes: Time travel has long been one of those "theoretically possible" things that makes Sci-Fi thrive. But while going forward in time is still perhaps possible, going back has been all but ruled out, according to an article (and accompanying videos) at LiveScience. Chiming in are four scientists who think about this a lot: Brian Greene, Charles Liu, Michio Kaku and J. Richard Gott. Liu flatly states: "It is not possible for you and me to travel backward in time."
