The serpent's tails coil together menacingly. A horn juts sharply from its head. The creature looks as if it might be swimming through a sea of stars. Or is it making its way up a sheer basalt cliff? For Bruce Masse, an environmental archaeologist at Los Alamos National Laboratory, there is no confusion as he looks at this ancient petroglyph, scratched into a rock by a Native American shaman. "You can't tell me that isn't a comet," he says.

| The FCX Clarity utilizes Honda's V Flow stack in combination with a new compact and efficient lithium ion battery pack and a single hydrogen storage tank to power the vehicle's electric drive motor. |
Honda has unveiled the FCX Clarity fuel cell vehicle at the Los Angeles Auto Show, announcing plans to begin limited retail marketing of the vehicle in summer 2008. The FCX Clarity is a next-generation, zero-emissions, hydrogen-powered fuel cell vehicle based on the entirely-new Honda V Flow fuel cell platform, and powered by the highly compact, efficient and powerful Honda V Flow fuel cell stack.

| The Aptera Typ-1 is loaded with safety features. They include a front crumple zone, a front end that re-directs crash energy in a frontal impact, steel and composite side and rollover protection as well as driver and passenger side airbags. |
Carlsbad, California - Electric Vehicles for Under $30K! Today, Aptera officially unveiled two vehicles that could change the future of automotive design. Aptera's Typ-1 is a radically different vehicle designed to marry advanced aerodynamics with light-weight composite technology creating an incredibly powerful, yet extremely safe vehicle that is a joy to drive -- even for the most performance-minded individuals.

The carnivorous pitcher plants that feed on insects in the Asian tropics may not snap shut like Venus flytraps, but they are smarter than they look.
Rather than being passive pitfall traps, the tube-like pitchers of Nepenthes plants actually contain a clever slimy fluid -- similar to mucus -- that produces powerful filaments to snare prey, French researchers said on Wednesday.

NEW YORK - Scientists have created the equivalent of embryonic stem cells from ordinary skin cells, a breakthrough that could someday produce new treatments for disease without the explosive moral questions of embyro cloning.
LONDON - This was a bug you couldn't swat and definitely couldn't step on. British scientists have stumbled across a fossilized claw, part of an ancient sea scorpion, that is of such large proportion it would make the entire creature the biggest bug ever. How big? Bigger than you, and at 8 feet long as big as some Smart cars.

| This is a computer generated image issued by the University of Bristol in England released on Tuesday Nov. 20, 2007 showing a size comparison between a human an ancient sea scorpion. A fossil found in Germany indicates the ancient sea scorpion was once 2.5 metres (8 feet) long, making it the biggest bug ever known to have existed. |
Climate change and conflict have gone hand-in-hand for the past 500 years, a study reveals.
Wine made some 2,400 years ago was found last Thursday in an ancient tomb in Baishui County, Shaanxi Province.
Local archaeologists said they unearthed a sealed bronze pot containing 2 kg of red liquid during an excavation of an ancient tomb built in the Warring States Period (475 BC - 221 BC). Wafts of the ancient vintage greeted the archaeologists after they opened the pot.

Many a mother has said, with a sigh, "If your friends jumped off a cliff, would you jump, too?"
The answer, for cockroaches at least, may well be yes. Researchers using robotic roaches were able to persuade real cockroaches to do things that their instincts told them were not the best idea.
