    'Lunar Ark' Proposed in Case of Deadly Impact on Earth Kevin Holden Platt for National Geographic News August 14, 2007 The moon should be developed as a sanctuary for civilization in case of a cataclysmic cosmic impact, according to an international team of experts. NASA already has blueprints to create a permanent lunar outpost by the 2020s. (Read: "Moon Base Announced by NASA" [December 4, 2006].) But that plan should be expanded to include a way to preserve humanity's learning, culture, and technology if Earth is hit by a doomsday asteroid or comet, said Jim Burke of International Space University...

    Cray Supercomputer at Sandia Helps Researchers Discover Origin of Mysterious Glass Found in King Tut's Tomb Released : Tuesday, July 31, 2007 7:26 AM Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that researchers running simulations on the Cray supercomputer at Sandia National Laboratories have re-created what could have happened 29 million years ago when an asteroid explosion turned Saharan sand into glass. The greenish natural glass, which can still be found scattered across remote stretches of the desert, was used by an artisan in ancient Egypt to carve a scarab that decorates one of the bejeweled breastplates buried...
  • Better Bombs: Scientists Develop Metal That Explodes on Impact

    When most bombs go off, they release a spray of deadly shards of steel. Now, imagine that those shards were themselves explosive, detonating in a massive chain reaction. It's for real: Defense contractors are harnessing the strange alchemy of reactive materials (RMs) — in which two or more inert materials are mixed to create an explosion — to develop smaller, more lethal warheads, as well as new ways to protect troops against mortar rounds and rocket-propelled grenades. RMs generally consist of powdered metals, such as aluminum or titanium, combined with an oxidizing agent. Whether that agent is another powdered metal...

    GRAND MARAIS, Minn. - A forest fire has led to a chance discovery of debris from the impact of a meteorite 1.85 billion years ago, more than 450 miles away at Sudbury, Ontario. Geologists had scheduled a field trip in May along the Gunflint Trail in northeastern Minnesota, but most areas they wanted to explore were closed because of a wildfire that charred more than 118 square miles. Geologist Mark Jirsa of the Minnesota Geological Survey went up the trail to scout new locations and, in a spot he had never visited before, stumbled across debris now linked to the...
  • Army Engineers’ Efforts Will Have Lasting Impact in Iraq, General Says

    WASHINGTON, July 13, 2007 – It will take time and considerable resources to rebuild Iraq following more than 25 years of neglect under Saddam Hussein’s rule, a U.S. military official told online journalists today. However, U.S. assistance is only part of a broader effort -- from both Iraqi and other donor nations -- that will have a lasting effect on the country’s infrastructure, said Army Brig. Gen. Michael Walsh, Corps of Engineers Gulf Region Division commander. Numerous relief and developmental funds have resulted in more than 3,300 completed projects for electricity, oil and water systems throughout Iraq. As of May,...

    WASHINGTON, July 13, 2007 – Ongoing anti-insurgent operations conducted in and around Baghdad and to the south of Iraq’s capital city are achieving continued success, a senior U.S. military officer said today during a teleconference with retired military analysts. Maj. Gen. Rich Lynch, commander of Multinational Division Center and U.S. Army’s 3rd Infantry Division, said he is optimistic that the surge will reduce violence in Baghdad while seriously disrupting insurgent operations in Iraq. “Eventually, I believe you’ll see (an) improved security situation inside of Baghdad” due to the surge operations, he said. “But, it’s not going to happen overnight.” Seeing...

Two University of Oregon researchers are on a multi-institutional 26-member team proposing a startling new theory: that an extraterrestrial impact, possibly a comet, set off a 1,000-year-long cold spell and wiped out or fragmented the prehistoric Clovis culture and a variety of animal genera across North America almost 13,000 years ago. Driving the theory is a carbon-rich layer of soil that has been found, but not definitively explained, at...

    MEXICO CITY - Mexico has lost more people to migration to the United States than death since 2000, according to a government report released Thursday. Mexico's demographics agency found that an average of 577,000 people migrated to the U.S. each year between 2000-2005, compared to 495,000 deaths a year in the same period. In 2006, 559,000 migrated and there were 501,000 deaths. Mexico had 104.9 million residents as of last year, an increase of 6.4 million since 2000. Immigration to the U.S. has increased drastically since 1970, when 800,000 Mexicans lived north of the border. Today, there are about 11...

    WASHINGTON, April 4, 2007 – The hard work U.S. troops are doing in Iraq is “laying the foundations of peace for generations to come,” President Bush told soldiers and family members today at Fort Irwin, Calif. “The work that you have volunteered to do will have a lasting impact on the world in which we live,” the president told the troops. By helping Iraq become a country that can sustain, defend and govern itself -- and become an ally in the war on terror -- the U.S. military will have delivered a significant blow to those who want to...

    UK impact crater debate heats up By Jonathan Fildes Science and technology reporter, BBC News Seismic surveys show a trough surrounded by concentric fractures A deep scar under the North Sea thought to be the UK's only impact crater is no such thing, claims a leading geologist. Professor John Underhill, from the University of Edinburgh, says the Silverpit structure, as it is known, has a far more mundane explanation. Detailed surveys reveal nine similar vast chasms in the area, he says. This suggests it was part of a more widespread process, probably the movement of salt rocks at depth, not...

    Recently, two lengthy immigration studies were released that made headlines across California for their unbelievable claims made by the authors on the impact of illegal immigration in our state. These so-called immigration experts at the Public Policy Institute of California and the Immigration Policy Center came to the misguided conclusion that illegal immigrants living in California actually help American workers earn higher wages, and break fewer laws than other demographic groups in our state. When asked about his conclusions, the co-author of one of the reports, Ruben Rumbaut, told a newspaper that he hoped his work would "reduce prejudice" ----...

    Global climate change is happening faster than previously believed and its impact is worse than expected, information from an as-yet unpublished draft of the long-awaited second part of a United Nations report obtained by SPIEGEL ONLINE reveals. No region of the planet will be spared and some will be hit especially hard. Is the world's weather already out of control? Is the pollution of the past decades having an impact on the present? That's exactly what the United Nations' Intergovernmental Panel on Climate Change fears: Human influences over the last 30 years "have had a recognizable effect on many physical...

    WASHINGTON - The sting of rising postal costs could be eased a bit by the introduction of a "forever" stamp that would remain valid for first-class postage despite future increases. The independent Postal Regulatory Commission scheduled a Monday morning briefing to announce its ruling on the Postal Service's requests to raise first-class rates 3 cents to 42 cents and to establish the permanent stamp. If the commission agrees, the matter goes back to the board of governors of the Postal Service, which is expected to schedule any rate changes in May. The commission can also reject or modify the rate...

    Mysterious Egyptian Glass Formed by Meteorite Strike, Study Says Stefan Lovgren for National Geographic News December 21, 2006 Strange specimens of natural glass found in the Egyptian desert are products of a meteorite slamming into Earth between 100,000 and 200,000 years ago, scientists have concluded. The glass—known locally as Dakhla glass—represents the first clear evidence of a meteorite striking an area populated by humans. At the time of the impact, the Dakhla Oasis, located in the western part of modern-day Egypt, resembled the African savanna and was inhabited by early humans, according to archaeological evidence (see Egypt map.)

    The new California law that requires registered domestic partners to file their state taxes like married people is a symbolic victory for gay couples. But the financial impact won't always be positive, and most will face new tax-filing and planning headaches when the law takes effect next year. Under SB1827, signed by Gov. Schwarzenegger last weekend, registered domestic partners can no longer file their state tax returns as single or head of household. For tax year 2007 and beyond, they can choose married filing jointly or married filing separately, the same options married couples generally have. However, domestic partners must...
