POPSWinter in Siberia Photos from a trip across Siberia in January 2006, when the average temperature was -60F. Just thinking of this numbing cold makes my bones ache, but the photos are lovely. Grab a cup of your favorite warm beverage and take a look at these photos of winter in Siberia.

POPSπ Pi(π) appears where you least expect it. Coincidentally, Pi Day is also the birthday of Albert Einstein, who no doubt knew more than a little about pi. Pi Day celebrants, usually children with an enthusiastic teacher and a varying degree of personal interest in the subject, learn about pi, circles, and, if they're lucky, eat baked pies of various sorts.

POPS'Major discovery' from MIT primed to unleash solar revolution Sunlight has the greatest potential of any power source to solve the world's energy problems, said Nocera. In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year. "This is a major discovery with enormous implications for the future prosperity of humankind,"

POPSThe way the brain buys Scientists used to assume that emotion and rationality were opposed to each other, but Antonio Damasio, now professor of neuroscience at the University of Southern California, has found that people who lose the ability to perceive or experience emotions as the result of a brain injury find it hard or impossible to make any decisions at all. They can’t shop. ergo we shop with our hearts..;-)

POPSHow Your Brain Controls Time
Warren Meck of Duke University argues that the brain measures long stretches of time by producing pulses. But the brain does not then count the pulses in the way a clock does. Instead, Meck suspects, it does something more elegant. It listens to the pulses as if they were music. At Humboldt University of Berlin in Germany, scientists have been building a model of how memory may store time. When neurons produce a regular cycle of signals, some signals come a little sooner and some come a little later. The researchers propose that as neurons pass these signals along, they can add tiny advances, some bigger than others. With these tiny wobbles, the brain can compress memories of time from several seconds down to hundredths of a second—a small enough package to store for later retrieval. As it stores time in memories, the brain may alter it in another way that is even more radical. It may record time so that our brains recall events in backward order. Scientists at MIT discovered re

POPSThe science of shopping IT MAY have occurred to you, during the course of a dismal trawl round a supermarket indistinguishable from every other supermarket you have ever been into, to wonder why they are all the same. The answer is more sinister than depressing. It is not because the companies that operate them lack imagination. It is because they are all versed in the science of persuading people to buy things—a science that, thanks to technological advances, is beginning to unlock the innermost secrets of the consumer’s mind

POPSHow the Personal Genome Project Could Unlock the Mysteries of Life ...You would very quickly begin to see meaningful and powerful correlations between particular genetic sequences and particular physical characteristics, from height and hair color to disease risk and personality. Church has done more than imagine such an undertaking; he has launched it: The Personal Genome Project, an effort to make those correlations on an unprecedented scale, began last year with 10 volunteers and will soon expand to 100,000 participants. It will generate a massive database of genomes, phenomes, and even some omes in between.

POPSNew Discovery Could Rejuvenate the Brain “If we can target therapies that block this mechanism, then neurons should be able to sprout new connections, therefore stimulating the brain’s ability to repair its wiring network.” The research reveals that the loss of plasticity is due to the protein calpain actively blocking the protein cortactin, which is responsible for the sprouting of new connections. The researchers reduced calpain activity in animal models to unlock the sprouting potential of neurons and found that when calpain activity is reduced neural plasticity is enhanced.

POPS"There is no question more important to us than our mortality" "A second possibility is more daring and probably much harder to become a reality. Combine human cloning with a mechanism to store all our memories in a giant database. Inject the clone of a certain age with the corresponding memories. Voil€! Will this clone be you? No one really knows. Certainly, just the clone without the memories won’t do. We are what we remember. To keep on living with the same identity, we must keep on remembering (unless you don’t like yourself). So, assuming such tremendous technological jump is even feasible, we could migrate to a new copy of ourselves.”

POPSOLDS: Preparing for a neuroscience revolution Our challenge is that we don't pay enough attention to such game-changing discoveries as they are happening. And when we don't pay attention, then the societal conversations that need to happen to reach consensus on policy also don't happen - at least in a proactive fashion. We end up reacting instead. In the case of the uncovering the secrets of the human mind, such proactive consideration would be better off earlier than later. The writer is James Olds is the director of the Krasnow Institute for Advanced Study at George Mason University. This is an important read.

POPSBreakthrough in Solar Energy: Scientists mimic plants' energy storage system 'GIANT LEAP' FOR CLEAN ENERGY Sunlight has the greatest potential of any power source to solve the world's energy problems, said Nocera. In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year. James Barber, a leader in the study of photosynthesis who was not involved in this research, called the discovery by Nocera and Kanan a "giant leap" toward generating clean, carbon-free energy on a massive scale. "This is a major discovery with enormous implications for the future prosperity of humankind," said Barber, the Ernst Chain Professor of Biochemistry at Imperial College London. "The importance of their discovery cannot be overstated since it opens up the door for developing new technologies for energy production thus reducing our dependence for fossil fuels and addressing the global climate change problem."

POPSSo,ladies,are you password protected? Only downside is you will have to change the password every time someone figures it out :-) Don't you just love the space invaders top? To every female clipper that is a gamer at heart! (myself included)

POPSDifferent conflicts demand different resolutions The first interesting result was that offering money or material goods in exchange for sacred ones did not make the sacred goods less valuable but more. Expressions of anger and disgust and of the willingness to use violence actually rose among moral absolutists when a deal involving giving up some sacred value was sweetened with material incitements, the second, more optimistic, result was that the absolutists who rejected with contumely the offer of profane money (or peace) for sacred landwould accept deals that involved their enemies giving up things that they considered sacred . The paper cites both Israeli and Hamas leaders saying that they could make peace if only the other side would apologise for 1948, or recognise formally Israel's right to exist. Demanding this kind of wholly intangible mutual surrender of pride makes no sense on a utilitarian calculus, and yet it may be the only thing to unlock the situation.
