But they grow up to 1.5 meters (5 ft) in length and can weigh over 300 kg (700 lbs), making them the largest of the hardshell sea turtles. The dorsal shell of the green turtle, or carapace, is wide, smooth, and brownish-olive in color. The underside of the shell, or plastron, is yellow. Green sea turtles are so named for the greenish hue of their skin. They have heads that cannot retract into their bodies, a trait commonly associated with turtles.
What Will The Ed Tech Revolution Look Like? During the past 40 years, accounting for inflation, we have nearly tripled the amount of money we spend per student in public K-12 education. It was roughly $4,000 in 1971, and last year amounted to $11,000 per student. Over that same period time, our students’ math and verbal test scores have remained unchanged. I am no Warren Buffett, but I can comfortably say to you that that is a lousy return on investment. Why 6-Year-Old Girls Want To Be Sexy (STUDY) By: Jennifer Abbasi, LiveScience Contributor Published: 07/16/2012 12:18 PM EDT on LiveScience Most girls as young as 6 are already beginning to think of themselves as sex objects, according to a new study of elementary school-age kids in the Midwest. Researchers have shown in the past that women and teens think of themselves in sexually objectified terms, but the new study is the first to identify self-sexualization in young girls. The study, published online July 6 in the journal Sex Roles, also identified factors that protect girls from objectifying themselves. Psychologists at Knox College in Galesburg, Ill., used paper dolls to assess self-sexualization in 6- to 9-year-old girls. Sixty girls were shown two dolls, one dressed in tight and revealing "sexy" clothes and the other wearing a trendy but covered-up, loose outfit.
Marine turtles Habitat loss and degradation Uncontrolled development has led directly to the destruction of critically important nesting beaches. Lights from roads and buildings attract hatchlings and disorient them away from the sea. Vehicle traffic on beaches compacts the sand and makes it impossible for female turtles to dig nests.

The Serious Eats Field Guide to Asian Greens [Photographs: Ben Jay, unless otherwise noted] When you walk into the produce section of your local Asian supermarket, you'll probably be greeted by a dazzling but daunting display of unusual greens. They're all great, and easy to cook, but it helps to be armed with some knowledge to tell your shoots from your choys. That's why we highlighted the most common varieties you'll find in Asian groceries with notes on what they are, how they taste, and most importantly, what to do with your haul. AA Choy
Crazy Smart: When A Rocker Designs A Mars Lander NASA engineer Adam Steltzner led the team that designed a crazy new approach to landing on Mars. Rachael Porter for NPR hide caption toggle caption Rachael Porter for NPR Richard Dawkins Foundation for Reason and Science Stone Age artists were painting red disks, handprints, clublike symbols, and geometric patterns on European cave walls long before previously thought, in some cases more than 40,000 years ago, scientists reported Thursday, after completing more reliable dating tests that raised a possibility that Neanderthals were the artists. A more likely situation, the researchers said, is that the art - 50 samples from 11 caves in northwestern Spain- was created by anatomically modern humans fairly soon after their arrival in Europe. The findings seem to put an exclamation point to a run of recent discoveries: direct evidence from fossils that Homo sapiens populations were living in England 41,500 to 44,200 years ago and in Italy 43,000 to 45,000 years ago, and that they were making flutes in German caves about 42,000 years ago. Then there is the new genetic evidence of modern human-Neanderthal interbreeding, suggesting a closer relationship than had been generally thought.
