It's not your average science fair when the 16-year-old winner manages to solve a global waste crisis. But such was the case at last May's Canada-Wide Science Fair in Ottawa, Ontario, where Daniel Burd, a high school student at Waterloo Collegiate Institute, presented his research on microorganisms that can rapidly biodegrade plastic. Daniel had a thought it seems even the most esteemed PhDs hadn't considered. Plastic, one of the most indestructible of manufactured materials, does in fact eventually decompose. It takes 1,000 years but decompose it does, which means there must be microorganisms out there to do the decomposing. Editor's note: There are two high school students who have discovered plastic-consuming microorganisms.
The first was Daniel Burd. The second was Tseng I-Ching (last month), a high school student in Taiwan. Could those microorganisms be bred to do the job faster?

We already know bees are pretty good at facial recognition, and researchers have shown they can also be effective air-quality monitors. Here's one more reason to keep them around: They're smarter than computers. Bumblebees can solve the classic "traveling salesman" problem, which keeps supercomputers busy for days. They learn to fly the shortest possible route between flowers even if they find the flowers in a different order, according to a new British study. The traveling salesman problem is an (read: very hard) problem in computer science; it involves finding the shortest possible route between cities, visiting each city only once.
Bees need lots of energy to fly, so they seek the most efficient route among networks of hundreds of flowers. To test bee problem-solving, researchers Lars Chittka and Mathieu Lihoreau tested bees' response to computer-controlled artificial flowers. Education environnement. Einstein was right - honey bee collapse threatens global food security. The agri-business lender Rabobank said the numbers of US bee colonies failing to survive each winter has risen to 30pc to 35pc from an historical norm of 10pc. The rate is 20pc or higher in much of Europe, and the same pattern is emerging in Latin America and Asia. Albert Einstein, who liked to make bold claims (often wrong), famously said that "if the bee disappeared off the surface of the globe, man would have only four years to live".
Such "apocalyptic scenarios" are overblown, said Rabobank. The staples of corn, wheat, and rice are all pollinated by wind. However, animal pollination is essential for nuts, melons and berries, and plays varying roles in citrus fruits, apples, onions, broccoli, cabbage, sprouts, courgettes, peppers, aubergines, avocados, cucumbers, coconuts, tomatoes and broad beans, as well as coffee and cocoa. This is the fastest growing and most valuable part of the global farm economy. China has its own problems. Einstein was not always wrong. Nature et jardin bio.
