Penguins are the acrobatic athletes of the seas, and they can keep diving for long periods of time because they have exquisite control over how and when their muscles use oxygen, new research indicates.
The penguins can switch between two modes of oxygen use — either starving their muscles or giving them an extra shot of oxygen to keep them working — to achieve their amazing dives.
“It appears that there’s a little bit of plasticity or variability in what they do when they are diving,” said study researcher Cassondra Williams of the University of California in San Diego. “It’s much more complicated than we thought.”
Almost 10 years later CC, aka Copy Cat, is still in the College Station area. She has a mate, Smokey, and they live with their three offspring in a cat mansion built by Dr. Duane C. Kraemer, an A&M researcher who helped bring CC into the world.
CC and her family seem like perfectly normal cats, which disappoints many guests hoping to see something more exotic, said Kraemer’s wife, Shirley, the head cat wrangler.
A&M’s cat-cloning operation was an offshoot of the Missyplicity Project to clone a dog named Missy with funding help from a company that wanted to market pet cloning. When the dog-cloning project had little success, researchers turned to cats. About 80 cat embryos were produced, but only one developed into a full-term pregnancy after being transferred to a surrogate mother.

The US revealed its “International Strategy for Cyberspace” (PDF) yesterday. It’s mostly blather about how terrific “cyberspace” is, but it gets more specific on a few key issues like national defense. Could our next war start because of a hack? The government says it’s possible.
“States have an inherent right to self-defense that may be triggered by certain aggressive acts in cyberspace,” says the policy. Indeed, such aggressive acts might compel a country like the US to act even when the hacking is targeted at an allied country.
“Certain hostile acts conducted through cyberspace could compel actions under the commitments we have with our military treaty partners,” says the document. “When warranted, the United States will respond to hostile acts in cyberspace as we would any other threat to our country.”
