New technology may help scientists decode dolphin communication. Florida-based dolphin researcher Jack Kassewitz and British acoustic engineer John Stuart Reid are analyzing dolphin sounds with an instrument called a CymaScope. The scope has a thin membrane that vibrates as sound passes through it. Then it converts those vibrations into a 3-D, high-definition image. Kassewitz hopes the unprecedented detail will solve some mysteries.
Pamela Martin is a geophysicist at the University of Chicago. She co-authored a 2009 study analyzing the environmental impact of an American diet based on meat versus a diet based on vegetables.
Pamela Martin: Right now the current mean American diet has 28% meat, but there’ nothing to say that if we all cut back to 10% that we would suffer nutritionally. And yet the environment would benefit quite a bit from that.
Martin’s study examined how much land a meat-based diet versus a vegetable-based diet would require to support Americans.
Pamela Martin: You need about four and a half times the amount of land to grow feed that you feed for cattle, versus using that land directly to grow food that we would directly consume.
Ultimately, Martin said, raising livestock requires more fertilizer and emits more greenhouse gases. These have environmental impacts.

The authors develop and test a multiclassifier-based near-real-time face detection system based on the premise that a three-part strategy is necessary for designing real-time face detection systems that provide high detection rates. The critical factors for real-time face detection are based on a framework of multiple classification functions: (1) a skin classification function is used as the preliminary stage in order to prune the search, localize the computation, and therefore improve performance time; (2) subsequently, three coarse-to-fine statistical model based classifiers are used to scan the windows and discard most non-face windows; and (3) finally, faces and non-faces are verified from images. The bagging ensemble algorithm (bootstrap aggregating) is also applied to improve the performance of detection rates.
