March 19, 2010: When the sun sets on Saturday, March 20th, a special kind of night will fall across the Earth. It's an equal night. Or as an astronomer would say, "it's an equinox." It's the date when the sun crosses the celestial equator heading north. Spring begins in one hemisphere, autumn in the other. The day and night are of approximately equal length. To celebrate the occasion, Nature is providing a sky show. It begins as soon as the sky grows dark. The Moon materializes first, a fat crescent hanging about a third of the way up the western sky. Wait until the twilight blue fades completely black and you will see that the Moon is not alone. The Pleiades are there as well. The Moon and the Pleiades are having a close encounter of rare beauty. There's so little space between the two, the edge of the Moon will actually cover some of cluster's lesser stars. According to David Dunham of the International Occultation Timing Association, this is the best Moon-Pleiades meeting over the United States until the year 2023.

This week, Mercury is emerging from the glare of the sun and making a beeline for Venus. By week's end, the two planets will be just 3o apart, an eye-catching pair in the deep-blue twilight of sunset. The best nights to look are April 3rd and 4th. Go outside at the end of the day and face west. Venus pops out of the twilight first, so bright it actually shines through thin clouds. Mercury follows, just below and to the right: April 3April 4 Venus is an old friend to most sky watchers; Mercury, less so. The first planet from the sun spends most of its time wrapped in painful sunlight. Seeing it so easily, and in the beautiful company of Venus no less, is a rare treat indeed. The next apparition this good won't come until Nov. 2011. By that time, however, we'll have much better view of Mercury all the time. NASA's MESSENGER probe is en route to Mercury now, and in March of 2011 it will become the first spacecraft to orbit the planet. During a year-long science mission, MESSENGER will beam back a stream of high-resolution pictures and data obtained using seven instruments designed to operate in the extreme environment near the Sun. This kind of coverage of planet #1 is unprecedented.

Zipping through space at nearly a million miles per day, NASA's New Horizons probe is halfway to Pluto and just woke up for the first time in months to look around. An artist's concept of New Horizons. "Our spacecraft is way out in exotic territory, in the middle of nowhere," says Hal Weaver, New Horizons project scientist at Johns Hopkins University. "And we have a lot to do." It's the perfect opportunity to test New Horizon's instruments before the probe reaches Pluto in 2015. "We don't want to miss a single breathtaking moment during the Pluto encounter," he says. "So we're checking everything out now to make sure we're ship-shape and ready to go." The 9 weeks of testing commenced on May 25th. Mission controllers plan a thorough checkout and recalibration of all seven science instruments onboard. First up is LORRI, the Long-Range Reconnaissance Imager, one of the largest interplanetary telescopes ever flown. "On July 14, 2015, the date of closest approach, we'll be able to distinguish objects on Pluto as small as a football field," says Weaver. "That's about 300 times better resolution than anything we have now."

Imagine you're a Brontosaurus1 with your face in a prehistoric tree top, munching on fresh leaves. Your relatives have ruled planet Earth for more than 150 million years. Huge and strong, you feel invincible. You're not. Fast forward about 65 million years. A creature much smaller and weaker dominates the Earth now, with brains instead of brawn. Its brain is a lot larger relative to its body size – plenty big enough to conceive a way to scan the cosmos for objects like the colossal asteroid that wrought the end of your kind. Right: An artist's concept of NASA's Wide-field Infrared Survey Explorer (WISE). [more] The creature designed and built WISE, NASA's Wide-field Infrared Survey Explorer, to search for "dark" objects in space like brown dwarf stars, vast dust clouds, and Earth-approaching asteroids. WISE finds them by sensing their heat in the form of infrared light most other telescopes can't pick up.

A team of evangelical Christian explorers claim they've found the remains of Noah's ark beneath snow and volcanic debris on Turkey's Mount Ararat (map). But some archaeologists and historians are taking the latest claim that Noah's ark has been found about as seriously as they have past ones—which is to say not very.

“CMS” stands for Compact Muon Solenoid, a general-purpose particle physics detector built on the Large Hadron Collider. The CMS project posted a few comics which provide a nice, simple (if somewhat cheesy) explanation of what the CMS/LHC does. The LHC generates massive amounts of data of all different varieties, which is distributed across a worldwide grid. It sends status messages to some of the computers, job monitoring info to other computers, bookkeeping info still elsewhere, and so on. This means that each location has specialized queries it can do on the data it has, but up until now it’s been very difficult to query across the whole grid. Enter the Data Aggregation System, designed to allow anything to be queried across all of the machines.

Realistic sound rendering can directly impact the perceived realism of users of interactive media applications. An accurate acoustic response for a virtual environment is attuned according to the geometric representation of the environment. This response can convey important details about the environment, such as the location and motion of objects. The most common approach to sound rendering is a two-stage process: Sound propagation: the computation of impulse responses (IRs) that represent an acoustic space. Audio rendering: the generation of spatialized audio signal from the impulse responses and dry (anechoically recorded or synthetically generated) source signals.

Rube Goldberg couldn’t have designed a more elegant confluence of convoluted causal relationships.  Start analyzing the perplexing paradox of the FPGA synthesis market and each link of the chain reveals a bizarre force vector that eventually doubles back onto itself into an unlikely equilibrium that miraculously has held stable for a full decade despite disruptive forces of epic proportions. For over a decade now, Synplify has navigated these waters and has continued to survive and thrive through the unlikeliest of conditions.  Now in the hands of EDA giant Synopsys, the Synplify family of FPGA synthesis tools continues to evolve - with a major upgrade this fall.  When you put a digital design into an FPGA, there are two technologies that determine whether your design fits or doesn’t fit, whether it meets your timing constraints or does not, whether the power consumption will be within your limits (or those of the FPGA), or whether it fails completely, leaving your project at the mercy of major mulligans.   Those two technologies are synthesis and place-and-route.

Flavor just got some competition. Smell and taste are known to converge to produce the best and worst of culinary experiences, but new research suggests that information received through the nose can also be altered by noise. If confirmed, this newfound union could have potent olfactory and gustatory implications.

Within the next three years, the U.S. military will test the feasibility of sending a quadruped robot out into the field as a trusty pack mule to carry supplies for its troops, wherever they go. If the testing goes well for Boston Dynamics's Legged Squad Support System (LS3), company founder Marc Raibert will have come a long way from the one-legged hopping robots he pioneered in the 1980s. Actually Raibert has already come a long way, to the point where the U.S. Defense Advanced Research Projects Agency's (DARPA) Tactical Technology Office and the U.S. Marine Corps awarded his company a 30-month, $32-million contract last week to deliver a prototype LS3. This would be the first step in fulfilling the military's call for an autonomous, legged robot that can carry up to 181 kilograms of supplies for at least 32 kilometers without refueling.

Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel. View the demos and sample applications to see a few of the visualizations that flare makes it easy to build. To begin making your own visualizations, download flare and work through the tutorial. You should also get familiar with the API documentation. Need more help? Visit the help forum (you'll need a SourceForge login to post). Flare is open-source software released under a BSD license, meaning it can be freely deployed and modified (and even sold for $$). Flare's design was adapted from its predecessor prefuse, a visualization toolkit for Java

Ice Energy has a novel solution for the electricity challenges of the 21st century: Make Popsicles. Put another way, the company wants to freeze water at night in refrigerator-like boxes adjacent to commercial air conditioners and then thaw it during the day, when power demand is highest. This would theoretically allow AC-hungry commercial buildings in warm climates to cut energy use during heat waves, by shutting air conditioners down while still providing cool air to buildings from melting ice. After seven years of development and testing, the Windsor, Colo.-based company signed an agreement recently with the Southern California Public Power Authority here to deploy some 6,000 Popsicle-making units at 1,500 locations in the utility's service territory around Los Angeles. Ice Energy says the units, called Ice Bears, will lead to a 30 percent fuel reduction for the utility through avoided use of so-called peaker generation plants, which are only turned on when demand is highest.

PMA is just kicking off in earnest down in Anaheim, and it looks like Sony has arrived in a big way. Looking to make a splash in a DSLR world dominated by Canon and Nikon, the outfit has brought a few of its best and brightest concepts to SoCal. Up first is an ultra-compact "interchangeable lens" concept, which is no doubt Sony's attempt to get in on the fledgling Micro Four Thirds game before it blows up big. Few details on the device are available, but we'll be doing our best to pry whatever specifications we can from the booth representatives in short order. Moving on, there's a conceptual model of the Alpha A700 replacement, complete with an Exmor APS HD CMOS sensor that promises full AVCHD video capabilities. There's also a prototype of a Super Telephoto Lens (500mm F4 G) as well as a prototype Distagon T 24mm F2 ZA SSM, which ought to make wide angle junkies drool profusely. The company's also dishing out a raft of accessories, including underwater housing devices, HD lenses and output cables, tripods / accessory packs and a Compact PictureStation photo printing kiosk. Stay tuned for some hands-on action from the show floor

Even in sleep, the human body is rarely still—and within it, there is the constant motion of the contents of our cells and the proteins within. Until now, scientists have had to estimate the speed of complex but common actions such as protein folding (which turns an unorganized polypeptide strand into a complex and useful three-dimensional protein). They could watch the action unfold, so to speak, in a test tube but weren’t sure how close the pace conformed to real life. A group of researchers at the University of Illinois at Urbana–Champaign, however, have developed a system to move the observation out of in vitro and into in vivo.

King Tut, depicted here by a gold funerary mask, was a frail pharaoh, according to a new DNA study. Tutankhamun was beset by malaria and a bone disorder—and possibly compromised by his newly discovered incestuous origins, researchers say. (Read the full story: "King Tut Was Disabled, Malarial, and Inbred, DNA Shows.")Released Tuesday by the Journal of the American Medical Association, the report is the first DNA study ever conducted with ancient Egyptian royal mummies. It apparently solves several mysteries surrounding the 14th-century B.C. pharaoh, including how he died and who his parents were."He was not a very strong pharaoh. He was not riding the chariots," said study team member Carsten Pusch, a geneticist at Germany's University of Tübingen. "Picture instead a frail, weak boy who had a bit of a club foot and who needed a cane to walk."

A deluge of high-energy physics data is headed toward servers in Geneva, Switzerland, later this month. That's because the European Organization for Nuclear Research (CERN) now says it plans to restart its Large Hadron Collider (LHC) soon for a run that could last as long as two years at a collision energy of seven TeV (tera–electron volts, 3.5 TeV per beam). As CERN ramps up the world's most powerful particle accelerator to operate well beyond its previous best performance, the lab's computer systems must likewise be tuned so they can properly capture and analyze all of this new output.
