Everyone seems to have a suggestion to get two wayward whales lingering in the Sacramento River to swim 70 miles back to the Pacific Ocean. One person suggested towing life-sized replicas of orcas behind the whales to scare the recalcitrant mother humpback and her calf. Another proposed placing a giant magnet downriver, since humpbacks are thought to navigate by an internal compass that can sense magnetic north.

The first animal to crawl onto land from the ocean probably looked a bit like today's salamander, and researchers have wondered how it was able to switch from swimming to walking. Now, European scientists have built a robot with a primitive electric nervous system that they say mimics that change in motion.

Nov. 24, 2004 - Scientists believe they have confirmed theories that homing pigeons are able to carry out their long-range navigational feat thanks to tiny magnetic particles in their upper beaks.

Researchers at a museum in central Japan have right whale fossils that are at least 5 million years old, making them the oldest fossilized remains of the animal in the world, officials said.

It sounds like a stretch, but a new study suggests that the missing evolutionary link between whales and land animals is an odd raccoon-sized animal that looks like a long-tailed deer without antlers. Or an overgrown long-legged rat.

Marine biologists say they have obtained the first proof that sharks can spot changes in magnetic fields, boosting evidence that the fish have an internal compass to guide them as well as a phenomenal sense of smell.
