POPSThe Mathematical Lives of Plants The seeds of a sunflower, the spines of a cactus, and the bracts of a pine cone all grow in whirling spiral patterns. Remarkable for their complexity and beauty, they also show consistent mathematical patterns that scientists have been striving to understand. ... Scientists have puzzled over this pattern of plant growth for hundreds of years. Why would plants prefer the golden angle to any other? And how can plants possibly "know" anything about Fibonacci numbers? For the first time, scientists have found convincing biochemical mechanisms responsible for the interlocking spiral growth patterns seen in many plants. (The Romanesco broccoli plant is a striking example.) The video of the experiment with magnetized liquid iron droplets demonstrates how the geometry of such growth could occur in nature.

POPSWho's Minding the Mind? New studies have found that people tidy up more thoroughly when there’s a faint tang of cleaning liquid in the air; they become more competitive if there’s a briefcase in sight, or more cooperative if they glimpse words like “dependable” and “support” — all without being aware of the change, or what prompted it. In describing my own research or cognitive science in general to people, the most difficult obstacle I would eventually encounter was the stubborn human belief that there was a independent entity — a free will — in charge of everything important that goes on in their brain. While science has been steadily dismantling this understandable misconception for decades, recent studies on subconscious social priming like these would have helped me demonstrate my point. To be fair, it's more than a little disconcerting to realize what a messy mix of competing, semi-independent, multi-layered neural modules are responsible for producing our daily behavior.

POPSKites could provide electricity for 100,000 homes Several other scientists are investigating the use of kites to harness energy from the wind - which some researchers estimate provides more than 100 times the amount required to power the entire planet. In 2007, Google´s philanthropic arm invested about $10 million in a US kite company called Makani. An Italian company called Kitegen has a multi-kite scheme that could generate a gigawatt of power, as much as a standard coal plant.

POPSLanguage Without Numbers: Amazonian Tribe Has No Word To Express 'One,' Other Numbers However, the MIT team decided to add a new twist--they started with 10 objects and asked the tribe members to count down. In that experiment, the tribe members used the word previously thought to mean "two" when as many as five or six objects were present, and they used the word for "one" for any quantity between one and four. This indicates that "these aren't counting numbers at all," said Gibson. "They're signifying relative quantities." He said this type of counting strategy has never been observed before, although it may also be found in other languages believed to have "one," "two," and "many" counting words.

POPSIntelligence and rhythmic accuracy go hand in hand “All in all, this suggests that a factor of what we call intelligence has a biological basis in the number of nerve fibres in the prefrontal lobe and the stability of neuronal activity that this provides,” says Fredrik Ullén.

POPSField Testing Third World Computers This is a very interesting experiment in access and education. The most interesting part is that the children are expected to fix the computers themselves! Actually, I learned a lot of stuff this way - by tinkering - but is it realistically applicable to all the kids? If it works, it will work brilliantly. It is certainly a new way of networking information. Maybe clipmarks should get in on something like this...

POPSBefore the beginning of the universe Alan Guth of MIT, who first proposed the inflation theory nearly three decades ago, says he suspects “the reported lopsidedness will more likely turn out to be a fluke.” However, he adds, “the concept of inflation is really only the framework of a theory, and so far experiment has given us very little guidance in trying to fill in the details.
