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.

POPSMirrors Don’t Lie.. : -) “When people are made to be self-aware, they are likelier to stop and think about what they are doing,” Dr. Bodenhausen said. “A byproduct of that awareness may be a shift away from acting on autopilot toward more desirable ways of behaving.” Physical self-reflection, in other words, encourages philosophical self-reflection, a crash course in the Socratic notion that you cannot know or appreciate others until you know yourself.

POPSNew Research On Octopuses Sheds Light On Memory It is not completely understood how these two systems are interconnected, if at all. However, the organization in the octopus demonstrates a sophistication that was not described yet in other animals. In the octopus, the short-term and long-term systems are working in parallel, but not independently. This is so because the long-term memory area -- in addition to its capacity to store long-term memories -- also regulates the rate at which the short-term memory system acquires short-term memories. This regulatory mechanism is probably useful in cases where faster learning is significant for the octopus' survival in emergency or risky situations.

POPSMore Evidence for a Revolutionary Theory of Water The current study is the most recent addition to a growing body of evidence for a new theory about the structure of liquid water. In 2004, Nilsson and colleagues sparked controversy with a paper published in Science that suggested the tetrahedral model of water was incorrect. Nilsson agrees that the debate is far from settled and that much work remains before a clear picture of liquid water emerges. "Over the last decade or so we have discovered that materials once considered homogeneous exhibit complex nanoscale order," said Stanford Synchrotron Radiation Laboratory director Jo Stöhr. "In my view, the work on water is yet another example of the actual complexity of matter, this time within a simple liquid. Modern X-ray work appears to be triggering a new understanding of liquids and we may have only seen the beginning of a paradigm shift in our understanding."

POPSSpore - A Computer Game to Teach our Children Long Term Thinking This game is about evolution and exploring our universe at all scales from the microscopic to the galactic. It is about the 'Big Picture' of life, and how to think about it in a multilevel multiscale fashion. It will give a real grasp of the complexity and interconnectedness of life, and will educate the players holistic long term thinking and planning. Watch the fascinating presentation of Will Wright in TED. Toys may change the world by changing us. I am all for it, and can't wait playing :-)

POPSBlue skies, scorched Earth? What is Global Dimming? If we were to eliminate global dimming all together without addressing global warming the increase in temperature and extreme weather might be more significant than previously predicted. This has been recorded with one full degree temperature change in just a few days of decreased pollution in the days following the 9/11 attacks . This reverse effect of dimming has been has been blamed along with global warming for increasing temperatures, appropriately called global brightening . No one wants smoggy skies but it could be smog and particulates that may be shielding us from the full consequences of the greenhouse gases we pump into our air daily. Clear blue skies are something many folks thinks of when they think of “going green” but those clear blue skies may hold more heat than we can handle.

POPSResearcher Links Storytelling, Math Ability This study suggests that building strong storytelling skills early in the preschool years may be helpful in preparing children for learning mathematics when they enter school. ''It is also a nice finding, I think, because storytelling is something every parent can easily do and foster with their children, without the need to buy any fancy toys or materials,'' said O'Neill. Given these findings, O'Neill is continuing in further studies, also funded by Science and Engineering Research Canada, to explore more precisely what aspects of storytelling are linked to aspects of mathematical ability.

The strategy that's proved most effective for computer Go is the Monte Carlo method, in which possible moves are assembled in a tree structure, and given statistical weight based on how likely they are to lead to a win."

POPSWhy nature can't be reduced to mathematical laws If so, then even perfect knowledge of the physics at one level would be inadequate for understanding organisation at higher levels. This conjecture has been debated ever since. Now Mile Gu at the University of Queensland in Brisbane, Australia, and colleagues, claim that it may be possible to prove Anderson's idea. They studied a basic mathematical model called the Ising model, which is often used to study how magnetism arises in iron and other materials from the collective organisation of their atoms. Using the model, the team focused on whether the pattern that the atoms adopt under various scenarios, such as a state of lowest energy, could be calculated from knowledge of those forces. They found that in some scenarios, the pattern of atoms could not be calculated from knowledge of the forces - even given unlimited computing power. In mathematical terms, the system is considered "formally undecidable".

POPSNew Mode Of Gene Regulation Discovered In Mammals As research advances, the more it becomes clear, that gene regulation networks are actually complex computing machines. DNA is not a mere repository of information. What's more, the newly discovered mechanism is self referential, which adds another later of complexity to gene regulation processes.

POPSHow To Think With the internet saturating ever deeper into our busy lives, humans are navigating uncharted informational and attentional waters these days. MIT neuroengineer, Ed Boyden, put together these rules of thumb to managing brain resources in an age of complexity. 7. Make your mistakes quickly. You may mess things up on the first try, but do it fast, and then move on. Document what led to the error so that you learn what to recognize, and then move on. Get the mistakes out of the way. As Shakespeare put it, "Our doubts are traitors, and make us lose the good we oft might win, by fearing to attempt." (Via Kottke.)
