Science In The News: Turtle, Hamsters, and Babies

1) New fossil provide insights into the evolutionary origins of the turtle shell.

“Over millions of years, rows of protective armour plates gradually fused together and to the reptile’s vertebrae, eventually creating a complete shell.”

2) Hamsters reveal details about the role of the circadian clock in memory.

“Working with Siberian hamsters, biologist Norman Ruby has shown that having a functioning circadian system is critical to the hamsters’ ability to remember what they have learned. Without it, he said, “They can’t remember anything.””

3) Infants seem to be capable of distinguishing happy music from sad music.

“One of the first things babies understand communicatively is emotion, so for them the melody is the message,” Flom said. “Our study showed that by nine months, babies are categorizing songs as happy or sad the same way that preschoolers and adults do”
