Edible Antifreeze

Borrowing a trick from the Arctic snow flea could banish freezer burn

Putting food back in the freezer after it thaws causes ice crystals to grow, imparting the unwelcome crunchy texture and mildew-like taste of freezer burn. Now food chemist Srinivasan Damodaran of the University of Wisconsin–Madison has derived an edible antifreeze from papaya enzymes and gelatin. His concoction, which stunts ice-crystal growth, promises always-creamy ice cream and juicier T-bones, even after their third trip between icebox and table.

Use It Better

Beef Up a Little PC

Turn the dirt-cheap, hardcover-size Eee PC into a speedy beast that can run any program or OS

If you want a super-light laptop, you have to pay for it, and you have to use Windows. That’s been the (frustrating) conventional wisdom—at least until late last year, when the Taiwanese company Asus rolled out the Eee PC (pronounced as though it were a single long “e”), a two-pound, seven-inch laptop starting at a mere $300. The tradeoff: It comes with just two to eight gigabytes of flash memory instead of a conventional, larger hard drive, and a simplified Linux operating system that essentially is usable only for e-mail, Web browsing and typing.

The Littlest Big Bang

Scientists are building ultra-cold systems that mimic the most extreme edges of the universe. Can these analogues help solve the big bang’s mysteries?

The device is a cylinder a bit smaller than a pinky finger, filled with helium and cooled to just above absolute zero. Inside, a young universe—or something very much like one—evolves. As the helium sloshes about, it mimics a process that may have powered our own universe a few moments after the big bang. And once the fluid settles down, the little whirlpools that remain may be akin to the defects in early spacetime that ultimately gave rise to galaxies, stars and planets.

The Drug Resurrector

One pharmacologist’s mission to recycle blockbuster drugs into treatments for neglected diseases

With Big Pharma spending upward of $1 billion to bring a single drug to pharmacy shelves, it’s little wonder that unprofitable afflictions like malaria and African sleeping sickness go largely ignored. Curtis Chong witnessed this neglect firsthand in 2001 as a third-year medical student working in an emergency room in Mozambique. Day and night, malaria patients lined up for treatment, but Chong’s medication stockpile was often too low or too antiquated to treat drug-resistant strains of the disease, and people were dying.

Six years later, the 31-year-old pharmacologist is spearheading an innovative way to bring better drugs, and more of them, to the developing world.

The Graffiti Laser

Combining salvaged parts and an unusual light source, a DIY slide projector beams strange, mesmerizing images from hundreds of feet away

Australian artist Chris Poole was driving around his native Perth recently, when some curbside garbage caught his eye. Unlike the average scavenger, Poole wasn’t searching for couches or chairs. He had his eye on an old slide viewer—a key component for his next project, a laser-based projector that could display family photos (albeit with a green hue) to the entire town.

Ducati: Leaner and Meaner

The famed manufacturer squeezes more horses into its slimmed-down motorcycle

Ducati upped the ante, unleashing a bike with an 849cc engine that weighs no more than competitors in the 600cc range. In fact, the Superbike 848 weighs 44 pounds less than its 749cc predecessor. To shed pounds, Ducati uses vacural molding, a fabrication process that inhales molten alloy directly into die casts to create a seamless piece of aluminum. This eliminates the need to fasten multiple pieces with welds and bolts that weaken a structure and add weight.

The Write Stuff?

Livescribe aims to revolutionize note-taking by linking your scrawl to audio recordings

Like previous “digital ink” pens, the Livescribe Pulse converts your writing to searchable computer files. The Pulse, though, adds audio recording synchronized to your handwriting. Point the pen to a spot in your notes (or click on your computer screen), and hear what was said when you wrote it. That sounds good on paper, but will it work, er, on paper?

Out of Control Gaming

A gesture-reading camera lets you play videogames without a controller

Soon you’ll be able to ditch your game pad and Wiimote. A new camera system for computers and consoles will track your movements in three dimensions—essentially turning your body into the game controller. For example, play Rock Band by waving your hands at imaginary drums, or dodge punches in a fighting game.

Inside the Tsunami Factory

What causes a monster wave? Scientists are drilling seismic hot zones to find out

Over the past 1,300 years, the Nankai Trough, the 500-mile-long boundary between two tectonic plates off the southwestern coast of Japan, has been one of the world’s most active tsunami hotspots. Now an international team of scientists has embarked on a multiyear project to drill four miles down into the heart of this subterranean wave machine. The Nankai Trough Seismogenic Zone Experiment, called Nantroseize, will be the first attempt to penetrate a tsunami-generating hotspot and could help scientists understand the source of the huge swells. “We can monitor the ocean all we want, but we’ll never understand why some earthquakes produce tsunamis and why others do not until we understand how faults work,” says geophysicist Nathan Bangs of the University of Texas.

The Lunar Habitat Hauler

NASA’s next lunar explorers will have a rugged, six-legged robotic helper to haul their home base wherever they want to go

The Winnebago isn’t exactly a marvel of technology. But there’s a good chance that NASA’s next generation of lunar travelers will live and work out of a two-piece system—a mobile robot and habitat combination that will allow astronauts to bring base camp with them—that has plenty in common with the humble RV.
