|Woolly Mammoth Resurrection
A team of Japanese genetic scientists aims to bring woolly mammoths back to life and create a Jurassic Park-style refuge for resurrected species. The effort has garnered new attention as a frozen mammoth is drawing crowds at the 2005 World Exposition in Aichi, Japan.
The team of scientists, which is not associated with the exhibit, wants to do more than just put a carcass on display. They aim to revive the Ice Age plant-eaters, 10,000 years after they went extinct.
Their plan: to retrieve sperm from a mammoth frozen in tundra, use it to impregnate an elephant, and then raise the offspring in a safari park in the Siberian wild.
"If we create a mammoth, we will know much more about these animals, their history, and why they went extinct," said Kazufumi Goto, head scientist at the Mammoth Creation Project. The venture is privately funded and includes researchers from various institutions in Japan. Story continues.
Hang in There: The 25-Year Wait for Immortality
Time may indeed be on your side. If you can just last another quarter century.
By then, people will start lives that could last 1,000 years or more. Our human genomes will be modified to include the genetic material of microorganisms that live in the soil, enabling us to break down the junk proteins that our cells amass over time and which they canít digest on their own. People will have the option of looking and feeling the way they did at 20 for the rest of their lives, or opt for an older look if they get bored. Of course, everyone will be required to go in for age rejuvenation therapy once every decade or so, but that will be a small price to pay for near-immortality.
This may sound like science fiction, but Aubrey de Grey thinks this could be our reality in as little as 25 years. Other scientists caution that it is far from clear whether and for how long science can stall the inevitable.
De Grey, a Cambridge University researcher, heads the Strategies for Engineered Negligible Senescence (SENS) project, in which he has defined seven causes of aging, all of which he thinks can be dealt with. (Senescence is scientific jargon for aging.) Story continues.
Unbelievable but true, you can buy land on the moon. That's right! Now for a limited time you can buy land on the Moon! There are over 1,125,000 lunar land owners from 176 countries around the world. To date more than 300 million acres have been issued to people from all walks of life here on planet Earth. For more information click here.
'Extreme Textiles' Come of Age
A knitted bag holds a weakened heart, helping it pump blood. Electricity flows through the threads of a battery-powered fleece jacket, keeping the wearer warm. Carbon fibers are braided into structures that look like mushrooms, but are actually prototypes of automotive engine valves. Other fibers are shaped into bicycle frames and sculling oars.
Textiles are no longer just the stuff of clothing, carpets and furniture covering. Made of high-tech threads, they can also be found in lifesaving medical devices and the bodies of racing cars. One architect is proposing building a skyscraper out of carbon fibers.
"I think there's more areas that are using textiles than there were before," said Matilda McQuaid, head of the textiles department at the Cooper-Hewitt National Design Museum, where 150 items showing the advances of materials science are on display in a show called "Extreme Textiles: Designing for High Performance."
In fact, textiles have long been used for more than clothes and rugs, said Dr. Peter Schwartz, head of the textile engineering department at Auburn University. "The Romans used jute fabrics for road stabilization," he said. Story continues.
