1. Governments should act now to save threatened turtles
   10-31-2006 · EurekAlert!
   Ecology and conservation experts from the University of Exeter today urge international governments to work together to protect threatened Caribbean sea turtle populations. The Cayman Islands, a UK Overseas Territory, once supported one of the world's largest sea turtle rookeries, which comprised some 6.5 million adult green and loggerhead turtles. These populations were driven into decline from the mid-1600s onwards, when massive harvesting of nesting turtles began. Only a few dozen individuals survive today.

   Ocean Conservancy Scientist, Wallace J. Nichols and University of California-Santa Cruz researcher Hoyt Peckham found surprising results in a recent peer-reviewed loggerhead sea turtle study that Nichols and Peckham conducted over the course of 10 years.

4. Small-scale fishing in Mexico rivals industrial fisheries in accidental turtle deaths
   10-16-2007 · EurekAlert!
   New research shows that a small-scale Mexican fishery -- operated by hand from small open boats -- can kill as many critically endangered loggerhead sea turtles as all of the industrial fishing fleets in the North Pacific Ocean put together. On a per-hook or per-net basis, the Mexican fishery is 10 to 100 times as deadly, the study found.

5. Nanotube, heal thyself
   02-15-2007 · EurekAlert!
   Pound for pound, carbon nanotubes are stronger and lighter than steel, but unlike other materials, the miniscule carbon cylinders remain remarkably robust even when chunks of their bodies are blasted away with heat or radiation. A Rice University study in the Feb. 16 issue of Physical Review Letters offers the first explanation: tiny blemishes crawl over the skin of the damaged nanotubes, sewing up larger holes as they go.

7. Animal studies in the land of the midnight sun illuminate biological clocks
   02-08-2007 · EurekAlert!
   How do animals living in the continuous light of the Arctic summer know when to sleep and when to be active? Do they maintain a 24-hour cycle of rest and activity, or does living in continuous light alter their circadian rhythm?Answering these questions may improve our understanding of biological clocks -- the internal, genetically programmed cycle of rest and activity that affects the behavior, metabolism and physiology of all animals, including humans.

8. College students know more about politics than pop culture
   04-12-2007 · EurekAlert!
   The "National Survey of Civic and Political Engagement of Young People" compared college students with young people not in college full time. Far from being self-absorbed, college students are civically and politically engaged, and more likely to be so than non-students. Surprisingly, those in both categories are far more likely to be able to name their US representative than the winner of "American Idol."

10. All change at the Earth's core
    08-16-2007 · EurekAlert!
    It is hard to know what is going on over 3000 kilometers beneath our feet, but until recently scientists were fairly confident that they understood the way the iron atoms in the Earth's core packed together. However, new research has overturned conventional thinking and revealed that the structure of the core is not as straightforward as was once thought.
