We may or may not recognize it, but fluid is a very integral part of our everyday lives. It decides everything from our fuel economy to (in some cases) how cool our computer runs. Until now, there was only one key way of deciphering the mechanics of fluids, and that was the Prandtl equation, developed in 1904. Sadly though, the Prandtl equation has many limitations, including only having the ability to calculate only two-dimensional problems, and a steady flow (such as that of a car traveling slowly). Thanks to a breakthrough by MIT’s George Haller, that’s all about to change.

A recently developed new equation, which is a product of four years of work by Professor Haller, will apply to three-dimensional and unsteady flows. This was confirmed with the aid of Thomas Peacock, the Atlantic Richfield Career Development Associate Professor at MIT, who lead experiments in order to validate the equation. Professor Peacock states, “This is the tip of the iceberg, but we’ve shown that this theory works.” The new work will probably go down as one of the greatest scientific advances of the decade, if it survives the peer review that will come.

This innovation in the mechanics of liquids will have an overwhelming influence on many industries, including aerospace, automotive and even computers. With these breakthroughs in calculating how liquids will act and perform in different environments, there’s no doubt that your PC’s liquid cooling system will soon get an overhaul.

Engineers have come up with a bit of sick technology, and we're not using that term as slang. Instead, they've found a way to assemble a key component of a microscopic battery using viruses, potentially paving the way for cheap and simple construction of pint-sized power sources.

The MIT group had previously been able to genetically engineer viruses to make a protein skin capable of attracting bits of metal, and this new research builds on that by having those same viruses build a specific part. In the MIT experiment, the genetically engineered viruses would help build the anode portion of a battery by attracting cobalt oxide. And more than just a proof of concept, the process has been drawing attention because of its ease-of-use and low cost.

One stumbling block preventing the widespread use of viruses in battery construction is a lack of application. There currently aren't any devices that would require a battery roughly one tenth the width of a human hair, though future applications could see the technology being used in nanotechnology.

Anyone else see the plot for a bad B-movie shaping up?

If the $100 laptop wasn’t enough a team at Massachusetts Institute of Technology is working on building a computer for $12, targeting families in Third World countries. They are basing their design on the old Nintendo Entertainment System. The NES used a MOS 6502 processor similar to the Apple IIe and Atari 2600 although it was a customized version for the NES.

The 6502 was designed in 1975. It is an 8-bit processor with a 16-bit address bus and clock speeds around 1 or 2 MHz. It is sure to smoke my digital watch.

Just how far the project will go is uncertain. Nintendo still holds the copyrights to the NES.

It sounds like a truly worthy project! You can check it out here.
