POPSArsenic-eating bacteria rewrite evolutionary history Oremland's team isolated and bred these bacteria in the lab. By growing them with with arsenite as the only possible food source, the researchers showed that the bacteria can indeed thrive. The results suggest that arsenic photosynthesis evolved at the same time, or even before, "normal" photosynthesis. Oremland says a similar mechanism might once have fuelled life on Mars or on Jupiter's moon Europa.

POPSIce Volcanoes of Titan May Habor Life For almost thirty years, scientists have known that complex carbon compounds called tholins exist on comets and in the atmospheres of the outer planets. Theoretically, tholins might interact with water in a process called hydrolysis to produce complex molecules similar to those found on the early Earth. Could tholins formed in Titan's atmosphere react with liquid water temporarily exposed by meteor impacts or ice volcanoes to produce potentially prebiotic complex organic molecules — before the water freezes? Laboratory research by Catherine Neish, a graduate student working on her doctorate in planetary science at the University of Arizona, suggests, not without controversy, however, that, over a period of days, compounds similar to tholins can be react with water at near-freezing temperatures.

POPSEnergy at your feet Finally, unlike roof-top solar arrays, which some find unattractive, the solar collectors in roads and parking lots would be invisible.” In the lab, small slabs were exposed to halogen lamps, simulating sunlight. Larger slabs were set up outdoors and exposed to more realistic environmental conditions, including direct sunlight and wind. The tests showed that asphalt absorbs a considerable amount of heat and that the highest temperatures are found a few centimeters below the surface. This is where a heat exchanger would be located to extract the maximum amount of energy. Experimenting with various asphalt compositions, they found that the addition of highly conductive aggregates, like quartzite, can significantly increase heat absorption, as can the application of a special paint that reduces reflection.

POPSMass Control Syndicate Frank Kern’s Mass Control marketing was one of the best product launchs I’ve seen in Internet Marketing history. His videos were brilliant but can the idea of “building a relationship with your list” really be that big a profit multiplier?

POPSCongressman Alcee Hastings On American Policy Center's "MOST CORRUPT" List And to top it all off, Mr. Hastings is a "Member in Good Standing" with the Florida Bar! Apparently the US Senate thought Hastings was too corrupt to be a Federal Judge, but the Florida Bar thinks Hastings wasn't corrupt enough to lose his Florida Bar Membership. Does the Florida Bar really oversee and enfoce ETHICS with their members who are supposedly, "Officers of the Court"? Seems not !

POPSGenetics Show How Prehistoric Cultures Migrated & Shared Knowledge The researchers tracked genetic variation on the Y chromosome, the sex chromosome passed from father to son that encodes maleness, using a technique now widely used that was developed in the early 1990s by Underhill and colleagues in the lab of Luigi Cavalli-Sforza, professor emeritus of genetics. The method has given scientists a powerful window into ancient human migrations and prehistoric cultural shifts. The technique has also been adopted by some commercial genealogy services that offer Y-chromosome testing to the public.

POPSAnthrax Mystery, In-Depth Podcast Must hear podcast. McCain tied the Anthrax attacks to Iraq in 2001 on the David Letterman show, to justify war, as did Bush (knowing there was no evidence to say such--lying). In-depth interviews here on Democracy Now podcast trace the clear evidence that whoever sent the letters engaged in purposeful propaganda to push the "War on terrorism" (Middle East regime change) and Homeland Security (fear-based) agendas. Also details about the suicide suspect Ivins by a person who knew him and the FBI's suspicious handling of the entire case. Alot of facts that the MSM is not covering while they parrot everything from the FBI without any investigation of their own former stories. (Interview in podcast follows headlines, etc...fast forward).

POPSNew Gear to Boost Space Station Population The station's new Water Reclamation System, a refrigerator-sized filtration and recycler unit, is designed to ease that shuttle dependence and help make larger crews more self-sufficient. It is scheduled to launch alongside the new toilet and phone booth-sized sleeping chambers in November aboard NASA's shuttle Endeavour, which will also ferry NASA astronaut Sandra Magnus to the station to join its Expedition 18 crew. 'By getting the crew quarters deployed, we'll have extra bedrooms,' Magnus said. The station's Russian Zvezda service module currently contains the station's main crew quarters.

POPSConfronting the Swirling Rumors of Discovery of "Life on Mars "The reason that all this seems so hush-hush is due to a future paper and press release that appears likely to pop out of the American Association for the Advancement of Science (AAAS) and its Science magazine. Whatever the poop is from the scoop that’s been studied by Phoenix, that information is purportedly going through peer-review."

POPSDr. Zack Overlooked as Anthrax Suspect This article is worth reading in its entirety. While dated 2002, it may have well been written yesterday, substituting the "suicided" suspect for what back then was Hatfill. The facts are relevant and suggestive. Dr. Zack seems to fit the profile of motive, means, and opportunity (access) , upon reading, then the now deceased. He is also a dual Israeli citizen with an obvious prejudice and gripe against Arabs, even if American citizens with whom he worked. Do not miss the anonymous letter to the FBI that called his Arab co-worker a "bioterrorist", which the FBI considered a hoax after investigation, and how close that sounds to the Anthrax hoax letters that said "Allah is great".
