    The many paths a message can take through the Internet make that network robust and efficient - and the envy of those whose job it is to design communications schemes for the far-flung spacecraft leaving Earth each year. After more than a decade of development, NASA is in a rush to have a communications network ready by 2011 that can efficiently carry data between Earth and the multiple probes, ro...

    A team of researchers from Germany and the Czech Republic has discovered that, all factors being equal, cattle and two species of deer tend to align themselves along a north-south axis using some innate magnetic sense and that this preferred alignment is disturbed when they graze under high-voltage power lines.

    The mobile-computing-device market is a little like the car market. On the high end, you've got your big, fully loaded luxury models- that would be your large-screen laptops. On the low end, you've got your park-anywhere, use- minimal- power gizmos-your smartphones. In between, you've got a range of sedans and lowcost compacts-your tablet PCs, subnotebooks, and netbooks.

    Capturing carbondioxide emissions and sequestering them deep underground is often presented as the sole means of significantly cutting the carbon emissions from a coal-fired power plant. In fact, this as-yet-unproven scheme is being beaten to the punch by a comparatively simple alternative: blending biomass into the plant's coal feed. View full abstract»

    For a small city in a water-poor country, Aqaba got lucky. The city of 110 000 sits on the Red Sea, on Jordan's only coastline. Residents get their water from 20 wells in the nearby Disi aquifer, a store of ancient groundwater that straddles the border with Saudi Arabia. While the rest of Jordan makes do with a few hours of water service a week, Aqaba's supply is uninterrupted. View full abstract»

    At first, the Pomegranate NS08 seems plausible as a sleek next-generation cellphone. But the list of features goes on just a tad too long to be true: a built-in translator (cool), a coffeemaker (please, please), a harmonica (huh?), and finally... an electric shaver (okay, you got me!).

    How many engineering jobs let you take a van Gogh off the wall and hold it in your hands? The kind C. Richard Johnson Jr. landed. He's both an electrical engineering professor at Cornell University, in Ithaca, N.Y., and an adjunct research fellow at the Van Gogh Museum, in Amsterdam. As such, Johnson says, he can "speak the language of people on both sides." View full abstract»

    There's no longer any excuse for having the wrong time. Computers, set-top boxes, and even some wristwatches can get their time from the U.S. Naval Observatory or some other authoritative source. But what about a device you build yourself? Many will come with a timing chip that you can use as a counter, but they won't tell you what time it is in the real world or self-adjust for daylight saving ti... View full abstract»

    Open one of the 179 "drawers" in Professor Stewart's cabinet, and you might find just a one-liner (Why did the chicken cross the Mobius band?") or a seven-page essay on Ferman's last theorem. It features a variety of knots, magic hexagons, square wheels, and topology tricks in which you pretend to slice off your finger. Answers are found at the back of the book and many have URLs for further infor... View full abstract»

    For several years now I've had Sonos envy. Several of my friends own these high-end multiroom audio systems; when dinner-party conversation lags, we pass the handheld controller around the table to play memorable songs and reminisce. (Okay, a bit strange, but this is Silicon Valley.) Unfortunately, Sonos systems are complicated and costly: Just the starter pack, with the wireless controller and bo... View full abstract»

    Germany stumbles in its move to replace coal and nuclear power with offshore wind energy. The six offshore wind turbines that REpower Systems began erecting near Germany's coast in 2004 make their older cousins look like pin wheels. Each one has three 61.5-meter blades, which in a good breeze make one revolution every 5 seconds, producing 5 megawatts of electric power. View full abstract»
