U.S. Government Wants To Track Its Citizens Through Their Cell Phones

Feds Push For Tracking Cell Phones -- CNET

Two years ago, when the FBI was stymied by a band of armed robbers known as the "Scarecrow Bandits" that had robbed more than 20 Texas banks, it came up with a novel method of locating the thieves.

FBI agents obtained logs from mobile phone companies corresponding to what their cellular towers had recorded at the time of a dozen different bank robberies in the Dallas area. The voluminous records showed that two phones had made calls around the time of all 12 heists, and that those phones belonged to men named Tony Hewitt and Corey Duffey. A jury eventually convicted the duo of multiple bank robbery and weapons charges.

From New Scientist:

SOMALI pirates terrorising the Indian Ocean are a hazard to more than shipping and tourists. They are also killing important scientific research and may be indirectly damaging the ocean's ecosystem.

Fishing boats in the Indian Ocean routinely carry scientists who gather data about fish stocks and threatened species while ensuring that boats comply with fishing rules. The piracy threat has put a stop to that. "We can't monitor and we can't do experiments because of the pirates," says Laurent Dagorn of France's Research Institute for Development (IRD).

On DARPA's List: A Real-Time, 3-D Picture Of The Earth Beneath Our Feet

Peering Inside the Earth DARPA's "Transparent Earth" would give both the military and civil authorities a real-time, 3-D view of processes in the Earth's crust, possibly allowing us to predict natural disasters like volcanic eruptions and earthquakes. NASA

From Popular Science:

DARPA wants to know what's happening in the skies overhead and seeks full situational awareness on the ground, so we suppose it's no surprise that now it wants full, real-time surveillance of what's happening beneath the surface. As part of the agency's fiscal 2011 budget, $4 million will go toward creating a system of sensors and algorithms that will create real-time 3-D maps displaying "the physical, chemical, and dynamic properties of the earth down to 5 km depth, including natural or man-made structures at militarily- relevant spatial scales."

Another Blizzard: What Happened To Global Warming?


From Time Magazine:

As the blizzard-bound residents of the mid-Atlantic region get ready to dig themselves out of the third major storm of the season, they may stop to wonder two things: Why haven't we bothered to invest in a snow blower, and what happened to climate change? After all, it stands to reason that if the world is getting warmer — and the past decade was the hottest on record — major snowstorms should become a thing of the past, like PalmPilots and majority rule in the Senate. Certainly that's what the Virginia state Republican Party thinks: the GOP aired an ad last weekend that attacked two Democratic members of Congress for supporting the 2009 carbon-cap-and-trade bill, using the recent storms to cast doubt on global warming.

Weather thwarts shuttle launches. But important factors favor this state.

If the space shuttle Endeavour lifts off in the early hours of Feb. 7, it will be the first shuttle launch in more than half a year to leave on time.

Each of the last three missions has been delayed for days or weeks – with one held back by a scheduling conflict and two by stormy weather. Despite its "Sunshine State" moniker, Florida has postponed shuttles due to five hurricanes, two hailstorms, a tropical storm, lightning damage, countless cloudy days, and meddlesome woodpeckers stabbing a fuel tank. And if the temperature goes below 36 degrees F., as it did earlier this month, Cape Canaveral's fickle weather will thwart yet another scheduled blastoff.

The Dawn Of Civilization: Writing, Urban Life, And Warfare -- Discovery Magazine

An extraordinary ancient Syrian settlement shines a light on one of the most important moments in human history.

Joan Oates’s sharp blue eyes spotted something that was not right. Standing on the windy summit of a vast, human-made mound in northeastern Syria, the wiry 81-year-old archaeologist noticed an ugly scar that had been left by a backhoe on one of the smaller mounds ringing the ancient city of Nagar, where she has excavated for a quarter century. Oates had just arrived to begin her latest season at the site, and this blemish on her cherished landscape annoyed her. Two young men on her team volunteered to investigate the damage. They returned, shaken. Jumping into the trench, one of them had come face-to-face with a skull. “Everywhere we looked, there were human bones,” one recalls. “There were an enormous number of dead people.”
