...This is the third aquatic documentary Howard Hall has directed for Imax, after Deep Sea 3-D and Into the Deep 3-D. Shot mostly in coral reefs around Indonesia and Australia, this one required lugging enormous equipment (total weight: 8,000 lb.) about in boats and logging vast numbers of hours under the sea for a mere 40 minutes of screen time. But the brevity of the film, and the spectacular oddness of the creatures, leave you - and, perhaps more crucially, your children - wanting more. Awww moments, the tentpoles of so many nature documentaries, are mostly reserved...
...good options and good incentives are not always enough. Sometimes people still need a helpful cue about their best choice, says Richard Thaler, a behavioral economist at the University of Chicago and author of Nudge: Improving Decisions About Health, Wealth and Happiness. Faced with a vast array of alternatives, many people--paralyzed--pick nothing, according to Thaler's research. "Sending people a bunch of options--that they can join health clubs or Weight Watchers or something--is probably not going to work," he says. What works is making good health effortless--say, by having a nurse come into the office...
...like a genetic cookbook, using four molecular "letters" to spell out recipes for everything from hormones to heart valves. Biologists today are reading the 3.5 billion letters in the human genome as well as the DNA from thousands of other species, and they've amassed vast databases of genetic information that they can rummage through to learn about how life evolved...
Biologists have documented a vast amount of gene-swapping among single-celled organisms - which happen to make up most of the diversity of life on Earth. There are 10,000 species of bacteria in a spoonful of dirt, twice as many species as all the mammals in the world. In the genome of a typical microbe, most of the genes hopped from one species to another at some point in the history of life. In some ways, the history of life is indeed like a tree, sprouting new branches. But in some ways, it's also like a tapestry, emerging...
...communities, so any infection can be a death sentence. The most vulnerable suffer the worst. One in five children in Congo will die before reaching the age of 5 - and will do so out of sight of the world, in places that camera crews cannot reach, deep in a vast landscape and concealed under a canopy of bucolic jungle...
