Russian scientists revive an ice age flower A plant that was frozen in Siberian permafrost for about 30,000 years has been revived by a team of Russian scientists — and borne fruit, to boot. Using tissue from immature fruits buried in fossil squirrel burrows some 90 feet below the surface, researchers from the Russian Academy of Sciences in Pushchino managed to coax the frozen remains of a Silene stenophylla specimen into full flower, producing delicate white blooms and then fruit. The findings, published this week in the journal Proceedings of the National Academy of Sciences, describe what is a record for reviving presumably dead plant tissue — and may provide clues as to what makes some plants hardier and longer-lived than others. "I'm absolutely thrilled with the result," said Grant Zazula, a paleontologist with the Yukon government in Canada who reviewed the study for the journal. "I've always been excited for the potential of something like this being successful."

Indian man single-handedly plants a 1,360-acre forest A little more than 30 years ago, a teenager named Jadav "Molai" Payeng began burying seeds along a barren sandbar near his birthplace in northern India's Assam region to grow a refuge for wildlife. Not long after, he decided to dedicate his life to this endeavor, so he moved to the site so he could work full-time creating a lush new forest ecosystem. Incredibly, the spot today hosts a sprawling 1,360 acres of jungle that Payeng planted — single-handedly. The Times of India recently caught up with Payeng in his remote forest lodge to learn more about how he came to leave such an indelible mark on the landscape. It all started way back in 1979, when floods washed a large number of snakes ashore on the sandbar. One day, after the waters had receded, Payeng, only 16 then, found the place dotted with the dead reptiles.

RSA Thursdays Florida Surfer Rescues Drowning Loggerhead Sea Turtle On a good day, a surfer is one with the ocean waves. On a really good day, he’s a hero, too. Cocoa Beach, Florida -- A surfer came to the rescue of a loggerhead sea turtle that was tangled in fishing lines just south of the Cocoa Beach Pier this afternoon. The turtle's flippers were so entangled that it could be seen gasping for air from the ocean's surface as it struggled to free itself from the mono-filament. Seeing the marine reptile in distress, a nearby surfer paddled over to help the sea turtle while risking a possible bite from the animal. Loggerhead sea turtles have a bite force so powerful, that they can easily tear through a conch shell - a mainstay of the turtle's diet.

DNA has a 521-year half-life M. Møhl Palaeogeneticist Morten Allentoft used the bones of extinct moa birds to calculate the half-life of DNA. OverviewSentinel Mission The spacecraft and instrument use high-heritage flight proven deep space systems, originally developed by NASA, to minimize technical and programmatic risks. These heritage missions include large space-based telescopes (Spitzer, Kepler), a large format camera made up of many individual detectors (Kepler), and a cryogenically cooled instrument (Spitzer). By detective and tracking nearly all of the Near Earth Objects greater than 50 meters in diameter, the Sentinel Space Telescope will create a map of the solar system in Earth’s neighborhood enabling future robotic and manned exploration. The data provided by Sentinel will also identify objects that are potentially hazardous to humans to provide an early warning to protect the Earth from impact. Features

Jack Russell Terrier And Jaguar Are Best Pals Jack Russell Terrier and jaguar are inseparable friends A pint-sized Jack Russell terrier named Bullet and his buddy Jag (you guessed it, a jaguar) prove that even the greatest feline-canine differences can be overcome. According to a video by Barcroft TV, Jag met Bullet when he was brought to South Africa's Akwaaba Lodge and Predator Park. The resort is home to many domesticated African cats that interact with guests. The Promise and Pitfalls of Resurrection Ecology Every species becomes extinct eventually. Some leave descendants that continue the evolutionary proliferation of life that kicked off on this planet over 3.5 billion years ago, but no parent species is immortal. Life on Earth is in continual flux, with new lineages emerging as others die back. But what if we could resurrect lost species?

Solar magnetism twists braids of superheated gas A rocket-borne camera has provided some of the sharpest images yet of the Sun's corona, the hot layer of gas that extends more than a million kilometres above the solar surface. The corona is millions of degrees hotter than the layer of gas beneath it, but nobody knows precisely why. "It's counter-intuitive for us here on Earth because as you go up in altitude, the temperature decreases," says Jonathan Cirtain, an astrophysicist at NASA's Marshall Space Flight Center in Huntsville, Alabama. Scientists Clone Long-Dead Animal Astounding even veterans of the fight against animal extinction, cloning technology has reproduced two endangered wild cattle bulls, each born to dairy cows last week on an Iowa farm. The procedure that created the bantengs has given animal conservationists hope that cross-species breeding can help reverse the daily disappearance of 100 living species and add genetic diversity to dwindling animal populations. If they survive, the two bantengs will be transferred to the San Diego Wild Animal Park and encouraged to breed with the captive population there. The technology is still fraught with problems and a long way from paying significant dividends.
