Physicists have rebuffed the existence of power laws governing the dynamics of traded stock volatility, volume and intertrade times at times of stock price extrema. They did this by demonstrating that what appeared as "switching points" in financial markets trends was due to a bias in the interpretation of market data statistics. This study by Vladimir Filimonov and Didier Sornette from the Department of Management, Technology and Economics at ETH Zurich in Switzerland is about to be published in the European Physical Journal B.

(Phys.org) -- The vascular system of a leaf provides its structure and delivers its nutrients. When you light up that vascular structure with some fluorescent dye and view it using time-lapse photography, details begin to emerge that reveal nature's mathematical formula for survival.

Seaweeds showing off their drag reducing skills.
Littered with the dehydrating corpses of seaweeds, beaches after a big storm are a reminder that life can be tough out there in the crashing waves. But seaweeds aren’t totally defenseless. A recent study in the American Journal of Botany studied two different strategies that seaweeds use to reduce drag so that fast-moving waves don’t uproot them.
Drag is proportional to the total area of the seaweed multiplied by drag coefficient, which depends on the seaweed’s shape. (For example, a boxy school bus has a higher drag coefficient than a race car.) That means seaweeds can either get smaller or more streamlined to ride out the waves.
Sea plants have adopted two main shapes—bladed and branched—to pursue these two strategies: Smoothly shaped bladed seaweeds crumple into smaller shapes when a wave hits them, while branched seaweeds fold their many (drag-generating) fronds into a more streamlined shape. The two approaches aren’t mutually exclusive, but they do manipulate different physical characteristics. Seaweed’s long, trial-and-error evolution has devised the same drag-reducing strategies that engineers have come up with.

On local TV last night, I somehow got reporter Dave Malkoff to take a stab at explaining quantum field theory: the world is made of fields, but we only notice the ripples within them, which we see as particles. Something about Angelina Jolie in there at the end as well.
