POPSStone Age Humans Crossed Sahara in the Rain Wet spells While about 40 per cent of hydrocarbons in today's dust come from water-dependent plants, this rose to 60 per cent, first between 120,000 and 110,000 ago and again from 50,000 to 45,000 years ago. So the region seemed to be in the grip of unusually wet spells at the time. That may have been enough to allow sub-Saharan Stone Age Homo sapiens to migrate north: the first fossils of modern humans outside Africa date from 93,000 year ago in Israel. And both genetic analysis and archaeology show that humans didn't spread extensively beyond Africa until 50,000 years ago, suggesting a second migration at the time of the second wet spell. Fossil record Ian Tattersall of the American Museum of Natural History in New York is impressed by the findings. "They tie in approximately with the information we have from the fossil record."

POPSGreat White Sharks Have Their Own Cafe
"Over an eight year period, nearly 100 sharks were electronically tagged, and even more had tissue samples taken by scientists working from a ship. Not only do the sharks consistently migrate along the same paths, they stick to a schedule too. Between August and December, the Great Whites -- which can grow up to six metres (20 feet) and three tonnes -- stalk waters off the coast of central and northern California, feasting on seals and sea lions. Their preferred hunting grounds in this area are known as the "red triangle", notes the study, published in the British journal Proceedings of the Royal Society B. Starting in January, they head for the deep blue around Hawaii some 4,000 kilometers (2,500 miles) to the west, where they are found in largest numbers between April and July. But some -- especially males -- loiter at a halfway point known as the "White Shark Cafe", with females coming and going for what scientists presume is a bit of shark intimacy. The new findi

POPSGreat Whites Hang Out in 'Shark Cafe' It had long been assumed shark species at the top of the ocean food chain that roam the high seas looking for food and mates did so almost randomly. But using satellite tagging, acoustic monitoring of shark "hot spots" and genetic samples, a research team led by Professor Barbara Block of Stanford University found to their surprise that the eastern Pacific's great whites are real homebodies. Over an eight year period, nearly 100 sharks were electronically tagged, and even more had tissue samples taken by scientists working from a ship. Sticking to a schedule They found that the sharks consistently migrate along the same paths and stick to a schedule. Between August and December, the great whites, which can grow up to six metres and weigh three tonnes, stalk waters off the coast of central and northern California, feasting on seals and sea lions. Their preferred hunting grounds in this area are known as the "red triangle", notes the study.

POPSSeas 'threaten 20m in Bangladesh' Four months after the cyclone, the sea defences are still breached and the island floods with every high tide. Map and satelite view of Gabura Island The chairman of the Gabura Island "union" or council, Shofiul Ajam Lenin, is calling for the embankments to be far higher. "If the current design is not changed then not only my union, but the other unions as well will not exist." The flooding has ruined the island's freshwater supplies and hygiene in the camp is poor. Among those living in tents on a narrow strip of high ground is Asma Khatun, a 25-year-old widow, who is now eager to leave. "I think it is not possible to live in this country any longer. We have to move to other countries. "We can't live here just by drinking this water. It is not possible to live here."

POPS'Suicidal' cows throw themselves off cliff cont: There has been speculation in the past that when this does happen it is because a tightly-grouped number of cows have followed each other as they search for more grass. Most scientists generally believe that animals are incapable of committing suicide. Even lemmings, which by popular myth throw themselves off cliffs during mating season, do not take their own lives intentionally. Instead, evolutionary pressures cause them to feel the urge to change habitat at which point they migrate in huge droves.

POPSEnding the Anchor-Baby Problem In an interview with Business Week, director of NumbersUSA.com, Rob Beck, said, “The U.S. should pass H.R. 1868--the Birthright Citizenship Act of 2009--so all babies born on U.S. soil are no longer automatically made citizens. “Maternity tourism is just the beginning of the silliness of birthright citizenship that goes to the babies of foreign students, temporary foreign workers, international travelers--and the millions who break the law to criminally enter this country.” With an astounding 400,000 anchor babies or “Jackpot babies” as named by radio talk show host Terry Anderson in Los Angeles, www.theterryandersonshow.com, American taxpayers pay a heavy price for a total misinterpretation of the 14th amendment of our Constitution.

POPSEverything You Need to Know About Plastic
Deplasticizing Your Food Chemicals are most likely to migrate from plastic into food when exposed to high heat, harsh soaps, and fat. These precautionary measures can help you play it safe. AVOID MICROWAVING IN PLASTIC. Heat speeds the release of chemicals into food. “People are being sold microwave-safe plastic, when in fact we’re not being told what’s in there and the rate at which these chemicals leach out,” says researcher Frederick vom Saal. Avoid this uncertainty by using ceramic or glass instead. EXPLORE THE ALTERNATIVES. “I have one word for you: glass,” says Terry Hassold, a professor of genetics at Case Western Reserve University in Cleveland, who has studied the health effects of bisphenol-A (BPA) on mice. You can also store your food in ceramic containers, waxed- and brown paper bags, and metal canisters made for hot and cold food. USE PAPER–NOT CLING-WRAP. Many studies indicate that most of the cling wrap used by delis and grocery stores contains high levels o

This coordinated effort includes several federal agencies and approximately $23 million in Fiscal Year (FY) 2007 for domestic programs to boost anti-trafficking law enforcement efforts, identify and protect victims of trafficking, and raise awareness of trafficking as a means of preventing new incidents. – Adapted from U.S. State Dept Trafficking in Persons Report, June, 2008

POPSMitsubishi makes bid for "most evil corporation around" title Because when you look at the prospect of imminent species extinction, OF COURSE your first thought is "hey, I can make money off this!" :mad: More: Fish stocks across the world are in retreat because of over-fishing. One study suggests oceans will be stripped clean of all fish by 2048. Bluefin is imminently at risk of commercial extinction. The wildlife charity WWF forecasts that breeding stocks of the fish that migrate from the Atlantic to spawn will be wiped out in the Mediterranean by 2012… conservationists suspect the actual catch is 60,000 tonnes, four times the maximum that marine scientists recommend. After studying catches and sales, Charles Clover, the environmental journalist behind the film The End of the Line, believes that businesses involved in the ransacking are deep-freezing 20,000 tonnes of bluefin a year for later use…
