POPSWhat is the worst environmental disaster in history? Despite the relatively small amount of oil released, several factors contributed to the spill's severity: timing, location, abundance of wildlife and substandard cleanup efforts. In comparison, one of the largest oil spills in history, the rupture of an oil well in the Gulf of Mexico that released 140 million gallons (3.3 million barrels) of oil, caused relatively little damage because it happened in the open sea where currents and winds contained it until it disintegrated.

POPSExperimental Data Recovered from Columbia Disaster Hard Drive In fact, the data was recovered in only two days, but it took nearly five years to process it in order to reveal the findings of the experiment. Other two hard drives on board Columbia, however, were not that fortunate and the information they were carrying was lost forever.

POPSWhy Having Big Buttocks Is Good for Your Health Working on mice, the team transplanted fat from one location of the animals' body to the other. Subcutaneous fat removed to the abdomen triggered body weight and fat mass losses, and a decrease in blood sugar levels. The rodents also got more responsive to insulin, the hormone controlling the way in which the body metabolizes sugar. Insulin resistance triggers the type 2 diabetes. When visceral fat was placed to other body regions, it induced no effect.

POPSIs a zero-carbon city on the horizon? As part of their Masdar Initiative (masdar meaning "the source" in Arabic), an effort to further the research and implementation of sustainable construction, the Abu Dhabi government will build this city on a nearby 2.3 square-mile site (six square kilometers), adjacent to its international airport at an estimated cost of $22 billion. It projected the city will eventually be able to sustain 50,000 residents and more than 1,000 businesses. It broke ground in construction of the city and hopes to complete the project by 2016.

POPSMoral Philosopher Questions Memory Manipulation Hurley says while the real threat of developing PTSD might be a good enough reason to use beta-blockers as a preventative measure, she also wants policy makers to consider the ramifications of what such a treatment may mean to a person’s moral well-being. “Beta-blockers do not cause amnesia. Rather they make memories less vivid, detailed and arousing,” explains Hurley, who specializes in bioethics. “They lessen the emotional impact when someone is recalling upsetting events.”

POPSWhat Does It Mean To Be Alive? To test this theory in the laboratory, Anggoro, who is now at the University of Chicago, and colleagues asked both Indonesian-speaking children and English-speaking children to identify entities that are “alive” in a simple sorting task. Indonesian-speaking children, tested in Jakarta, exhibited little trouble; they selected both plants and animals. But, English-speaking children, tested in Chicago, had trouble settling on the scope of the concept, and even at 9 years of age tended to exclude plants. Thus, the term “alive” poses unique interpretive challenges, especially for English-speaking children.

POPSNew Nanotechnology Products Hitting The Market At The Rate Of 3-4 Per Week While polls show most Americans know little or nothing about nanotechnology, in 2006 nanotechnology was incorporated into more than $50 billion in manufactured goods. By 2014, Lux Research estimates $2.6 trillion in manufactured goods will incorporate nanotechnology--or about 15 percent of total global output. Despite a 2006 worldwide investment of $12.4 billion in nanotech R&D, comparatively little was spent on examining nanotechnology's potential environmental, health and safety risks.

POPSThe InnerSpace Foundation A founding philosophy of The InnerSpace Foundation is that the shortest and most efficient path to solving humanity's most serious problems--including providing complete and lasting cures for the most diseased and disabled--is through widespread improvement of memory and mind, rather than through the best efforts of people who are well-meaning but of naturally limited abilities.

POPSEvolution: 24 myths and misconceptions So here is New Scientist's guide to some of the most common myths and misconceptions about evolution.Everything is an adaptation produced by natural selection Natural selection is the only means of evolution Natural selection leads to ever-greater complexity Evolution produces creatures perfectly adapted to their environment Evolution always promotes the survival of species It doesn't matter if people do not understand evolution "Survival of the fittest" justifies "everyone for themselves" Evolution is limitlessly creative Evolution cannot explain traits such as homosexuality Creationism provides a coherent alternative to evolution

POPS'Babelfish' to translate alien tongues could be built But Deacon argues that all languages arise from the common goal of describing the physical world. That limits the way a language could be constructed, he concludes. An alien race could use a strange medium like scents as their language, Deacon says, but the scents would still describe objects in their world. An odour that communicates "rock" or "tree" would be analogous to our words for the same objects. So there must be an underlying universal code that can be deciphered, as in mathematics.

POPSPioneering Physicist John Wheeler Dies at 96 a real genius, if i am not mistaken he was Hugh Everett III's professor of physics, also he is the one the suggested the 'delayed choice' experiment that showed the experimenter can choose, AFTER THE FACT, whether the photon was in both places or just one.

POPSClues To Ancestral Origin Of Placenta Emerge In Genetics Study They found that the placenta develops in two distinct stages. In the first stage, which runs from the beginning of pregnancy through mid-gestation, the placental cells primarily activate genes that mammals have in common with birds and reptiles. This suggests that the placenta initially evolved through repurposing genes the early mammals inherited from their immediate ancestors when they arose more than 120 million years ago.

POPSBefore the Big Bang - the Big Bounce Now, however, Dr Bojowald and fellow physicists are exploring territory unknown even to Einstein - the time before the Big Bang - using his new theory, called Loop Quantum Cosmology. An analysis of this, one of a series of newly-emerging theories which combine Einstein's theory of gravity (general relativity) with that of the subatomic world (quantum theory), "is supposed to provide a non-singular framework in which one could address the question of what was there before the Big Bang," he says.

POPSDa Vinci's mother was a slave, Italian study claims The fact that the banker's widow continued to live in the house, soon hiring a new servant, forms the basis for the theory that Ser Piero allowed her to stay in return for freeing Caterina. The slave woman disappears from the Florence records thereafter. On April 15 1452, Da Vinci was born in Vinci. A few months later, his mother married one Acchattabriga di Piero del Vaccha.
