Why should the whale study lead scientists to “change the way we view sleep”? Among whales, the priority is that babies not drown in the first weeks of life. Maturational processes thought to occur during sleep, such as brain development, might have to be put on hold while this critical lesson is learned. Our neonatal […]

Are there data concerning evolutionary development in whales? Matthew KabriskyDayton, Ohio “Learning to Listen: How some vertebrates evolved biological sonar” (SN: 5/14/05, p. 314) […]

New Fossils Resolve Whale’s Origin
The first discovery of early whale fossils with key ankle bones intact provides compelling paleontological evidence that whales are closely related to many living ungulates, a relationship already supported by molecular data.

Even deep down, the right whales don’t sink
A right whale may weigh some 70 tons, but unlike other marine mammals studied so far, it tends to float rather than sink at great depths.

Deep-sea gear takes wild ride on lava
When a set of instruments monitoring an underwater volcano got trapped in an eruption in early 1998, the scientists who had deployed the sensors ended up with more data than they bargained for.

Study picks new site for dinosaur nostrils
A new analysis of fossils and living animals suggests that most dinosaurs' nostrils occurred at locations toward the tip of their snout rather than farther up on their face, a concept that may change scientists' views of the animals' physiology and behavior.

Minke whales make Star Wars noises
Researchers have identified the dwarf minke whales of Australia as the source of an odd sound like the firing of a Stars Wars laser gun.

Chimps grasp at social identities
Researchers contend that neighboring communities of wild chimpanzees develop distinctive styles of mutual grooming to identify fellow group members and foster social solidarity.

Time to revise right whales’ family tree?
A statistical analysis of DNA from nearly 400 right whales around the world suggests there may be three species of Eubalena, not just two—a conclusion that may boost conservation efforts.
