"The new full body scanners going into airports across the United States are being hailed as the next great innovation in airport security, but the truth is that most Americans do not understand what these machines actually do. The reality is that these machines produce an image that is the closest one can get to seeing someone's exposed body without actually seeing their skin. Every curve, every crevice and every detail of the bodies of every passenger will be completely exposed to the eyes of gawking airport security officials. In addition, a number of scientific experts are now claiming that the technology used by these scanners actually is damaging to human DNA. But even with all of these concerns, new polls reveal that an overwhelming majority of Americans want these machines to be installed in U.S. airports. So are you ready to walk through full body scanners that give security officials a crystal clear look at your completely exposed body? Democratic political strategist James Carville apparently is.... "Let me buy a [security] card, then go and measure my *****, and let me get on the airplane." But is this the way that the new "Amerika" has to be? A place where all dignity and all privacy is completely thrown out the window? A place where there is no shame and where we are all reduced to little more than cattle to be herded around and embarrassed? But not only are these new full body scanners a threat to privacy, they are also potentially dangerous to our health."

"A seriously damaged national port. An already swamped airport. Hospitals in shambles. A homeless president. No fuel. A capital city without phone service or electricity. As military and rescue teams began to stream in Thursday from the U.S. and other countries, veterans of past disasters say the grim realities of the Haiti earthquake set it apart from many other calamities, including the 2004 tsunami that devastated communities around the Indian Ocean, killing an estimated quarter million people. "There are a lot of dimensions that make this an especially complicated situation," said Steve Hollingworth, chief operating officer at the Atlanta-based relief group CARE. Haiti's almost nonexistent government and its battered infrastructure are among the top challenges that will plague relief efforts in coming days and weeks, aid veterans say. Also high on their lists: the country's extreme poverty and history of violence. "When a country's capital city is decimated, you lose a lot in terms of staging and organization," said Randy Martin, head of global emergency operations at Mercy Corps International. Little organization and crumbling infrastructure has stalled relief efforts in Haiti, where time is running out for possible survivors in the rubble. Military and aid groups began to encounter huge obstacles getting relief into the country, less than two days after the earthquake killed an estimated 45,000 to 50,000 people. U.S. military specialists reestablished communications at the Port-au-Prince airport, but a lack of fuel and a crammed tarmac prompted the Haitian government to halt incoming flights. While one airport runway was usable, air-traffic control was limited, able to handle only four aircraft at a time, logistics companies said. "

Last week's foiled airline bombing plot by a Nigerian man who hid explosives in his clothing has renewed debate in the United States as to how extensive and invasive passenger screening should be at U.S. airports. A few major airports already possess machines that can take detailed, full-body images, but Congress has not mandated widespread use of the technology. Air travelers worldwide are accustomed to passing through metal detectors. But in an era of plastic explosives and advanced chemical compounds, that system has proved lacking. Kip Hawley is a former head of the U.S. Transportation Security Administration, or TSA, which is charged with screening airline passengers and luggage. "The number one area we need to focus on, the biggest potential vulnerability, is a bomb on the body," said Hawley. Dutch officials have ordered detailed, full body scans of all U.S.-bound air travelers. Terrorism expert M.J. Gohel of the London-based Asia Pacific Foundation applauds the move. "These scanners are, in fact, very effective," he said. "They actually show a person's body - any foreign object attached anywhere in the body, even if it is internally. That kind of x-ray scanner would have located the package that this individual [Umar Farouk Abdulmutallab] had on the flight to Detroit. They are on a trial basis at the moment."

"PORT-AU-PRINCE, Haiti - Prayers of thanksgiving and cries for help rose from a roofless cathedral and the huddled homeless Sunday, the sixth day of an epic humanitarian crisis that was straining the world's ability to respond and igniting flare-ups of violence amid the rubble. A leading aid group echoed complaints about the supply bottleneck and skewed priorities at the U.S.-controlled airport. The general in charge said the U.S. military was "working aggressively" to speed up deliveries. In the ruins of the Port-Au-Prince cathedral, gathered beneath shattered stained glass for their first Sunday Mass since Tuesday's earthquake, survivors were told by their priest, "We are in the hands of God now." But anger mounted hourly that other helping hands were slow in getting food and water to millions in need. "The government is a joke. The U.N. is a joke," Jacqueline Thermiti, 71, said as she lay in the dust with dozens of dying elderly outside their collapsed nursing home near the airport. "We're a kilometer (half a mile) from the airport and we're going to die of hunger." Water was delivered to more people around the capital, where an estimated 300,000 were living in the streets, but food and medicine were still scarce. Pregnant women gave birth in the streets. The injured arrived in wheelbarrows and on people's backs at hurriedly erected field hospitals. Authorities warned of looting and violence. In downtown Port-au-Prince, where people set bonfires to burn uncollected bodies, gunfire rang out and bands of machete-wielding young men, their faces covered with bandanas, roamed the streets."

"Call it the mystery of the missing thermometers. Two months after "climategate" cast doubt on some of the science behind global warming, new questions are being raised about the reliability of a key temperature database, used by the United Nations and climate change scientists as proof of recent planetary warming. Two American researchers allege that U.S. government scientists have skewed global temperature trends by ignoring readings from thousands of local weather stations around the world, particularly those in colder altitudes and more northerly latitudes, such as Canada. In the 1970s, nearly 600 Canadian weather stations fed surface temperature readings into a global database assembled by the U.S. National Oceanic and Atmospheric Administration (NOAA). Today, NOAA only collects data from 35 stations across Canada. Worse, only one station -- at Eureka on Ellesmere Island -- is now used by NOAA as a temperature gauge for all Canadian territory above the Arctic Circle. The Canadian government, meanwhile, operates 1,400 surface weather stations across the country, and more than 100 above the Arctic Circle, according to Environment Canada. Yet as American researchers Joseph D'Aleo, a meteorologist, and E. Michael Smith, a computer programmer, point out in a study published on the website of the Science and Public Policy Institute, NOAA uses "just one thermometer [for measuring] everything north of latitude 65 degrees." Both the authors, and the institute, are well-known in climate-change circles for their skepticism about the threat of global warming. Mr. D'Aleo and Mr. Smith say NOAA and another U.S. agency, the NASA Goddard Institute for Space Studies (GISS) have not only reduced the total number of Canadian weather stations in the database, but have "cherry picked" the ones that remain by choosing sites in relatively warmer places, including more southerly locations, or sites closer to airports, cities or the sea -- which has a warming ef

"PORT-AU-PRINCE, Haiti - Scores of U.S. troops landed on the lawn of Haiti's shattered presidential palace Tuesday to the cheers of quake victims and the U.N. said it would throw more police and soldiers into the sluggish global effort to aid the devastated country. The U.N. forces are aimed at controlling outbursts of looting and violence that have slowed distribution of supplies, leaving many Haitians still without help a week after the magnitude-7.0 quake killed an estimated 200,000 people. Looters were rampaging through a part of downtown Port-au-Prince even as the Security Council was voting to add 2,000 troops to the 7,000 military peacekeepers already in the country as well as 1,500 more police to the 2,100-strong international force. Haitians jammed the fence of the palace grounds to gawk and cheer as U.S. troops emerged from six Navy helicopters. "We are happy that they are coming, because we have so many problems," said Fede Felissaint, a hairdresser. Given the circumstances, he did not even mind the troops taking up positions at the presidential palace. "If they want, they can stay longer than in 1915," he said, a reference to the start of a 19-year U.S. military presence in Haiti - something U.S. officials have repeatedly insisted they have no intention of repeating. A full week after the quake, the capital's port remains blocked and the city's lone airport remains a chokepoint that the U.S. military is trying to expand. Tens of thousands of people sleep in the streets or under plastic sheets in makeshift camps. Relief workers say they fear visiting some parts of the city."

"PORT-AU-PRINCE, Haiti - Desperately needed aid from around the world slowly made its way Thursday into Haiti, where a leadership vacuum left rescuers scrambling on their own to save the trapped and injured and get relief supplies into the capital. President Barack Obama announced that "one of the largest relief efforts in our recent history" is moving toward Haiti, with thousands of troops and a broad array of civilian rescue workers flying or sailing in to aid the stricken country - backed by more than $100 million in relief funds. To the Haitians, Obama promised: "You will not be forsaken." The nascent flow of rescue workers showed some results: A newly arrived search team pulled a U.N. worker alive from the organization's collapsed headquarters. He stood, held up a fist in celebration, and was helped off to a hospital. Planes carrying teams from China, France, Spain and the United States landed at Port-au-Prince's airport with searchers and tons of water, food, medicine and other supplies - with more promised from around the globe."

"CHICAGO (AP) - A would-be terrorist tries to board a plane, bent on mass murder. As he walks through a security checkpoint, fidgeting and glancing around, a network of high-tech machines analyzes his body language and reads his mind. Screeners pull him aside. Tragedy is averted. As far-fetched as that sounds, systems that aim to get inside an evildoer's head are among the proposals floated by security experts thinking beyond the X-ray machines and metal detectors used on millions of passengers and bags each year. On Thursday, in the wake of the Christmas Day bombing attempt over Detroit, President Barack Obama called on Homeland Security and the Energy Department to develop better screening technology, warning: "In the never-ending race to protect our country, we have to stay one step ahead of a nimble adversary." The ideas that have been offered by security experts for staying one step ahead include highly sophisticated sensors, more intensive interrogations of travelers by screeners trained in human behavior, and a lifting of the U.S. prohibitions against profiling. Some of the more unusual ideas are already being tested. Some aren't being given any serious consideration. Many raise troubling questions about civil liberties. All are costly. "Regulators need to accept that the current approach is outdated," said Philip Baum, editor of the London-based magazine Aviation Security International. "It may have responded to the threats of the 1960s, but it doesn't respond to the threats of the 21st century." Here's a look at some of the ideas that could shape the future of airline security:"
