| Earth Experiencing "Climates" Change? [The following is an exact transcript of this podcast.]Climate change is the great environmental challenge facing the world today. But maybe we should start calling it “climates change”. Because scientists who’ve looked to glaciers to study the history of climate on Earth have found that the Northern and Southern hemispheres have not been moving in sync. [More] rss.sciam.com |

Eat Flipper? Stealthy filmmakers spotlight Japanese dolphin slaughter in The Cove The time is ripe for a masterful documentary that weaves a riveting yarn from the collapse of the world’s fisheries and Japan’s heartless pursuit of the ocean’s last great bounty from bluefin tuna to blue whales. The Cove is not that film. At its core, The Cove is about the capture and slaughter of dolphins for meat in a heavily guarded inlet in Taiji, Japan, and the activists who seek to end this hunt. These activists include Richard O’Barry, the dolphin trainer who regrets his work on the TV series Flipper in the 1960s, and Paul Watson, the controversial captain of the Sea Shepherd who made Taiji’s dolphin hunt known through footage he posted on YouTube in 2003. All this is used, somehow, to also put the spotlight on the world’s declining fisheries. To director Louie Psihoyos, the lines are clear: you are either an “activist” or an “inactivist,” and this perspective (or lack thereof) becomes the film’s greatest flaw, reducing it from what could have been a powerful piece of undercover journalism to propaganda.

iSniff: Pocket-Size Pollution Sensors Promise Big Improvement in Monitoring Personal Environment Once large enough to be mistaken for terrorist bombs, portable air pollution monitors are now being shrunk into smaller and smaller wearable devices that can be easily dispatched for environmental detective work: Is black carbon soot emitted by school buses contributing not just to warming global temperatures , but raising childhood asthma rates, too? These new pocket-size sensors could provide more practical and powerful detection of such potential public health risks. [More] rss.sciam.com |
Cracked Corn: Scientists Solve Maize's Genetic Maze The complex corn genome--coming in at a hearty two billion base pairs (compared with the human genome's 2.9 billion base pairs)--has been mapped by more than 150 researchers, who worked for years to decipher the grain's genetic code . It's the most complicated plant genome to be deciphered to date and promises to increase the efficiency of the crop itself. [More] rss.sciam.com |
