"One example is famadihana - the turning of the bones - a traditional ritual carried out by the Malagasy people of Madagascar. Every seven years, the dead relatives are exhumed from the family tomb, re-wrapped, and danced around the tomb."

POPSThe Secret Of Fast Complex Brain Restructuring Up to now, it had been assumed that nerve cells can only exchange information via the synapses which are special contact points. However, synapses require up to two days to become fully functional - a waste of time and energy if the contact is to be broken down again. The brain could take almost 1000 years to develop if a synapse had to mature at each cell contact. It appears that nerve cells can also obtain information about their neighbours even without a synapse. Neurobiologists Christian Lohmann and Tobias Bonhoeffer from the Max Planck Institute for Neurobiology have now explained how they do that. The secret to how the information is exchanged: local calcium signals very quickly transmit all the necessary information to the cell. A synapse only actually develops when the cell and the contact point prove to be suitable candidates for long-term contact.

POPSA New State Of Mind But that view of the neurotransmitter was vastly oversimplified. What wasn’t yet clear was that dopamine is also a profoundly important source of information. It doesn’t merely let us take pleasure in the world; it allows us to understand the world.

POPSNano-Solar Power -Will it Be the Next Revolutionary Technology? Not that the technology is perfect. The system can absorb energy very well, but that's no good to anyone until they work out a way to harvest it from the sheet - when you're dealing with a hyper-complex web of millions of units oscillating at trillions of cycles per second, you can't just solder copper wires to the ends and call them plus and minus. This isn't a mistake or a weakness in the concept though; it's an issue because no-one has ever done this before. You know, the kind of thing that happens with cutting edge invention.

POPSPotential Alzheimer's, Parkinson's Cure Found In Century-old Drug Also impressed is one of Dr. Atamna's co-authors, Bruce Ames, PhD, a senior scientist at Children's and world-renowned expert in nutrition and aging. "What we potentially have is a wonder drug." said Dr. Ames. "To find that such a common and inexpensive drug can be used to increase and prolong the quality of life by treating such serious diseases is truly exciting." Dr. Atamna's research is the first to show that low concentrations of the drug have the ability to slow cellular aging in cultured cells in the laboratory and in live mice. He believes methylene blue has the potential to become another commonplace low-cost treatment like aspirin, prescribed as a blood thinner for people with heart disorders.

POPSIs it so different? "After the female deposits her unfertilized eggs into the male, the outer shell of the eggs breaks down, and tissue from the male grows up around the eggs in the pouch. After fertilizing the eggs, the male closely controls the prenatal environment of the embryos in his pouch. The male keeps blood flowing around the embryos, controls the salt concentrations in the pouch, and provides oxygen and nutrition to the developing offspring through a placenta-like structure until he gives birth." " in some species of pipefish, the sex roles are reversed because males become pregnant and there is limited brood pouch space. So females compete for access to available males, and thus secondary sex traits (such as brightly colored ornamentation) evolve in female pipefish instead of males."

POPSRobin Hanson on the "Great Filter" there is a "Great Filter" along the path between simple dead stuff and explosive life. The vast vast majority of stuff that starts along this path never makes it. In fact, so far nothing among the billion trillion stars in our whole past universe has made it all the way along this path.... ne or more of these steps is much more improbable than it otherwise looks. If it is one of our past steps, such as the development of single-cell life, then we shouldn't expect to see such independently evolved life anywhere within billions of light years from us. But if it is a step between here and a choice to explode that is very improbable, we should fear for our future.... Optimism (as defined here) regarding our future is directly pitted against optimism regarding the ease of previous evolutionary steps. To the extent those successes were easy, our future failure to explode is almost certain...

POPSSwitching it up: How memory deals with a change in plans The answer is "both," according to researchers at The Johns Hopkins University, who have learned that two different areas of the brain are responsible for the way human beings handle complex sets of "if-then" rules. "This discovery may eventually lead to enhanced understanding of psychiatric diseases such as schizophrenia, obsessive-compulsive disorder and attention deficit disorder, all conditions in which a person's ability to remember and change such rules is impaired," "This indicates that different parts of our brains store different kinds of memories and information," Courtney said. That, she said, "provides clues about how the human brain accomplishes complex, goal-directed behaviors that require remembering and changing abstract rules, an ability that is disrupted in many mental illnesses."

POPSConverting DNA Structures into Music Highly complex DNA structures can be tranformed into musical sounds, which might eventually be used to monitor sick patients. In the acoustic translation, harmony represents good health, and discord indicates disease. Finally auditory information will allow surgeons, anesthesiologists, and other physicians to be able to focus on their task and listen at the same time.

POPSUnderstanding the "Predator State" Full of thought-provoking analysis of how corporate America gained control of government. Lots to think about here. Looks like a must-blog piece. The clip is only intro to the good stuff.

POPSFuturistic Excavation However, Weyrich noted, Princeton's system will never replace the experience, contextual knowledge and "soft skills" that conservators and archaeologists bring to the table. "Reconstructing these frescoes is incredibly complex, given the condition of the fragments and the sheer number of fragments," said Weyrich. "The computer takes over the laborious parts of the process while leaving the important, intuitive decisions to the humans." i wonder when this will change as well.

POPSTaliban kills 70 Pakistanis in suicide attack The Kamra Air Weapon Complex and Heavy Industries Taxila are also contained within the Wah Cantt. Taxila "is devoted to land combat systems," Global Security notes, while Kamra is believed to be connected with Pakistan's nuclear weapons program. The Pakistani Ordnance Factories are believed to store nuclear weapons at a "screwdriver level" - meaning the components are stored disassembled and can be assembled within hours of use.

POPSTaliban Launches Large Coordinated Assaults The Taliban claimed responsibility for all three attacks in Khost. Their spokesman, Zabiullah Mujahed, reached by telephone at an unknown location, said that 15 suicide bombers, equipped with machine guns and vests packed with explosives, with 30 militants backing them up, attacked the base, one of the largest foreign military bases in Afghanistan. He claimed that some of the bombers had gotten inside the base and had killed a number of American soldiers and destroyed equipment and helicopters. This last claim was denied by General Azimi of the Afghan military.

POPSYour Bi-Lingual Kitty "It’s kind of nice to think your kitty has gone to the effort to learn a second language to communicate with you. Sure, she did it mostly out of necessity, but also out of affection. She wouldn’t meow just for your attention if she didn’t enjoy a relationship with you."

POPSLet Them Eat Rice: Washington's Unedifying Ethanol Food Fight And what about the impact of the Chinese livestock and meat complex, alluded to by Senator Grassley? According to China expert, Darrell Ray, Director of the University of Tennessee's Agricultural Policy Analysis Center, "China has not been importing corn to grow her livestock industry. China continues to export more corn that she imports. With regard to grains, China has been taking care of China as if it were a planet on to its own, completely independent of what is happening elsewhere. . . .To attribute today's international grain prices to China essentially assumes that beginning two years ago the market decided there may be a need for China to become a net importer of some corn in the future, say 2012, and so bid-up the price of corn by double." As this "let them eat rice" soundbite made clear, the debate over the food versus fuel issue is about as undignified as a full out real food fight at a summer camp cafeteria.

POPSResurgent Taliban in Afghanistan Another result of "successful" troop surge in Iraq? As forces that could be used in Afghanistan continue to be diverted to Iraq the failure of the US/NATO Afghan war becomes even clearer.

POPSIs McCain another George W. Bush? "George Bush's record as a student, military man, businessman and leader of the free world is one of constant failure. And the part that troubles me most is he seems content with himself." "He will leave office with the country $10 trillion in debt, fighting two wars, our international reputation in shambles, our government cloaked in secrecy and suspicion that his entire presidency has been a litany of broken laws and promises, our citizens' faith in our own country ripped to shreds. Yet Bush goes bumbling along, grinning and spewing moronic one-liners, as though nobody understands what a colossal failure he has been." "I fear to the depth of my being that John McCain is just like him."

POPSGeorgia-Ossetia: Context!! Georgia has massacred Ossetians for centuries; Ossetians have sought Russian protection. And this one began with Georgians (now aligned with the West) slaughtering Ossetians - again! Wake up, Cold Warriors, this is not about Big Bad Russia picking on pure-as-the-driven-snow helpless neighbor. Every player has mixed motives.
