POPSPersian Clouds - NLC's going south
Spaceweather says: "Noctilucent clouds (NLCs) are supposed to be a high-latitude phenomenon, most often seen in Canada, Russia and northern Europe. On July 19th the electric-blue clouds crept south, all the way to Iran: "I took this picture from Mt. Sabalan, a 15,784 ft extinct volcano in northwestern Iran," says Siamak Sabet. "It is the third highest peak in our extremely mountainous country." When noctilucent clouds first appeared in the late 19th century, they were confined to latitudes above 50o N. Mt Salaban is located at 38o N, far below the old threshold. Just last week, NLCs were sighted in Turkey at 40o N and in recent years they have appeared at least as far south in the United States as Colorado and Utah, also around 40o N. Why are NLCs spreading south? That is an unsolved mystery of these puzzling clouds. Some researchers believe it is a telltale sign of climate change, but this remains controversial. One thing is certain: Sky watchers at all latitudes should be ale

POPSMugtada al-Sadr keeps the truce for now.... Cont.... Such tales abound. Sudani said she'd heard of troops bursting into a woman's home and arresting her four sons, as a soldier threw the mother to the ground and put his boot on her head. Iraqi troops are said to have seized gasoline canisters from a Sadr City resident and distributed them to others, claiming they were from the government. Ali Jassim, 30, another resident, said his cousin's phone rang at a checkpoint with a ringtone containing a chant about Sadr. When soldiers heard it, they slapped him, he said. Sadr's militia, the Mahdi Army, has suffered a series of setbacks since last spring. It lost control of Basra, Iraq's second-largest city, and the southern city of Amara after Prime Minister Nouri al Maliki ordered his forces to retake those areas. Many charge that Maliki is waging a political war against his former allies in time for fall's provincial elections.

POPSVaTech, D.O.E, Russians, collaborators study rare microorganism that produces hydrogen So we finally found a clean energy solution ? guess not - no2liberals writes "I’m all for new sources of energy, but one has to look at the downside. The only emission from hydrogen as a fuel is water vapor, which happens to be the single greatest greenhouse gas. Do we really want vehicles and power plants spewing more of the gas that traps 80% of all radiant heat within the first thirty feet of atmosphere?"

POPSDrilling, Not Earthquake, Caused Java Mud Volcano Lusi is still flowing at 100,000 cubic meters per day, enough to fill 53 Olympic swimming pools. It appears that the flow will continue indefinitely and so far all efforts to stem the flow have failed. Recent research in which Davies was involved showed it is collapsing by up to three meters overnight and could subside to depths of more than 140 metres, having a significant environmental impact on the surrounding area for years to come. Indonesian President Susilo Bambang Yudhoyono has declared the 400 hectare area inundated by the mud flow as a disaster-prone area unfit for human habitation.
