Nathan Myhrvold's Anti Global Warming Scheme
From Associated Content:
Nathan Myhrvold is a former technology officer for Microsoft who has found his own company, Intellectual Ventures, which is involved in a number of technology development programs, including new forms of energy generation.
Nathan Myhrvold also thinks that he has found a cheap and reliable way to solve global warming, which does not involve upending and perhaps destroying the world's economy. The global warming solution proposed by Nathan Myhvold involves Nathan Myhrvold's Anti Global Warming Scheme running a hose up to the stratosphere with balloons and using that hose to pump out enough sulfur particles to dim the sun's heat just enough to counteract the effects of global warming. The estimated cost would be about two hundred and fifty million dollars.

The Air Force's Next-Gen Bomber
The B-2 It's bad, but the brass wants something badder. The next-generation of bombers will conduct extensive intelligence, surveillance and reconnaissance missions, as well as carry directed-energy and other non-kinetic weapons. Air Force's Next-Gen Bomber Will Be More Spy Plane Than Strike Aircraft -- Popular Science
It turns out the Air Force's next-gen bomber really isn't much of a bomber at all. While the next iteration of stealth bombers is still but a sketch on the drawing board, the DoD and top Air Force command know what the wars of the next century will call for: intelligence, surveillance, and reconnaissance (ISR), as well as the ability to deploy non-kinetic weapons to disrupt enemy operations, all while reserving the ability to drop the occasional ordinance -- and do it all at the same time with a single, stealthy super-weapon.

Using snake-like fangs, saber-toothed dinosaur relatives of velociraptors likely subdued their prey with venom, scientists now suggest.
Paleontologists analyzed the skulls of Sinornithosaurus, whose name means "Chinese bird lizard." This narrow-snouted raptor was the fifth and most bird-like dinosaur species ever to be discovered, and lived roughly 125 million years ago in the warm, moist forests of northeastern China during the late Cretaceous.

Inflated Expectations: Crowd-Sourcing Comes of Age in the DARPA Network Challenge -- Scientific American
The M.I.T. and Georgia Tech teams proved most successful in using social networks to pinpoint the locations of 10 red weather balloons scattered throughout the U.S.
The U.S. Defense Advanced Research Projects Agency's (DARPA) Network Challenge earlier this month demonstrated that social networks, more than being platforms for self-promotion, can be also be highly effective tools for rapidly gathering and disseminating very precise information. With the help of Facebook, Twitter and a homemade Web site, a winning team from the Massachusetts Institute of Technology (M.I.T.) was able to within nine hours identify the correct latitude and longitude of all 10 of DARPA's red weather balloons, which were lofted 30.5 meters into the air at locations scattered throughout the U.S.

Czech Zoo Sends Rare Northern White Rhinos To Kenya
From the BBC:Four rare Northern White rhinos have been flown from a Czech zoo to Kenya, in a desperate attempt to save the species from extinction.
Animal experts hope the rhinos - two males and two females - will breed in their natural habitat in Africa.
Only eight Northern White rhinos are known to survive worldwide, all of them in captivity: six in the Czech Republic and two in the US.
The last four living in the wild in Africa have not been seen since 2006.

Winter Solstice 2009: What It's All About
A statue greets the 2003 winter solstice sunrise in San Juan Bautista, California. Newscom/FIleFrom Christian Science Monitor:
Winter solstice 2009 falls Monday, marking the shortest day in the year for the Northern Hemisphere.
Ah, another winter solstice come and gone.
At 5:47 p.m. Greenwich Mean Time (that's 12:47 p.m. Eastern Standard Time) Monday, the Northern Hemisphere marked the mid-point of another year, as measured by the sun's highest position each day above the horizon. It marked the day with the fewest hours of sunlight this year.
Yes, this is showing a Northern Hemisphere bias. South of the equator, the day marks the most hours of sunlight of the year. So enjoy the austral summer, those of you below the equator. The rest of us? We'll be rooting for longer, warmer days.

From ABC News (Australia):
It won't make Jurassic Park a reality, but scientists have discovered 419 million-year-old DNA intact inside ancient salt deposits.
The genetic material, the oldest ever found, belongs to salt-loving bacteria whose ancestors may have been among the first life forms on Earth.
Scientists have previously recovered similar genetic material from the Michigan Basin, the same region where the latest discovery was made. But the DNA was so similar to that of modern microbes that many scientists believed the samples had been contaminated.
Not so this time around.

The Real Reason Cell Phone Use Is Banned On Airlines
From Live Science:
Airline passengers who sneak in cell phone calls, play with gaming devices or listen to their mp3 players during takeoff or landing probably won't cause a plane crash, but they may risk a confrontation with flight attendants. Federal agencies and airlines typically err on the side of caution — even though researchers and aircraft companies have found almost no direct evidence of cell phones or other electronic devices interfering with aircraft systems.

Yellowstone's Plumbing Exposed
Image: Seismic imaging was used by University of Utah scientists to construct this 3-D picture of the Yellowstone hotspot plume of hot and molten rock that feeds the shallower magma chamber (not shown) beneath Yellowstone National Park, outlined in green at the surface, or top of the illustration. The Yellowstone caldera, or giant volcanic crater, is outlined in red. State boundaries are shown in black. The park, caldera and state boundaries also are projected to the bottom of the picture to better illustrate the plume's tilt. Researchers believe "blobs" of hot rock float off the top of the plume, then rise to recharge the magma chamber located 3.7 miles to 10 miles beneath the surface at Yellowstone. The illustration also shows a region of warm rock extending southwest from near the top of the plume. It represents the eastern Snake River Plain, where the Yellowstone hotspot triggered numerous cataclysmic caldera eruptions before the plume started feeding Yellowstone 2.05 million years ago.From E! Science News:
The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume, only shallow hot rock moving like slowly boiling soup. A related University of Utah study used gravity measurements to indicate the banana-shaped magma chamber of hot and molten rock a few miles beneath Yellowstone is 20 percent larger than previously believed, so a future cataclysmic eruption could be even larger than thought.

Spitzer’s Cold Look At Space
From American Scientist:To get a clear view of infrared emissions from celestial objects, the Spitzer Space Telescope has been cryogenically cooled—and what sights it has seen.
In astrophysical observations, more is more—imaging across multiple wavelengths leads to richer information. One electromagnetic band in which most celestial bodies radiate is the infrared: Objects ranging in location from the chilly fringes of our Solar System to the dust-enshrouded nuclei of distant galaxies radiate entirely or predominantly in this band. Thus, astrophysicists require good visualization of these wavelengths. The problem, however, is that Earth is a very hostile environment for infrared exploration of space, as the atmosphere also emits in the infrared spectrum and additionally absorbs much of the incoming signal. Even heat produced by a telescope itself can degrade its own clarity.
