Elephant Seal Pups Learn To Adapt To Life At Sea

Seal pup season is coming to a close in California. When adult elephant seals leave the beach, pups are on their own as they prepare to live out at sea for months at a time. This means pups must learn to sleep underwater. Jessie Kendall-Barr and other researchers at the Dan Costa lab at UC Santa Cruz are studying how.

Timing is Everything: Modern life has ravaged our circadian rhythms, but could we reset them?

You can’t hear them ticking, but our bodies are full of tiny clocks—and scientists have just taken a major step toward understanding how they work. A collaboration of three University of California research labs has created a biological clock in a test tube.

“Understanding how these clocks work provides a powerful tool for future researchers to figure out–and perhaps one day even manipulate–the rhythms that govern our lives,” says Carrie Partch, a UCSC scientist who studies the biochemistry of biological clocks.

Biological clocks in our cells work together like an orchestra of timekeeping, controlling the circadian rhythms—the mental, physical and behavioral changes within a 24-hour cycle—that keep our bodies in sync with day and night. Circadian rhythms have a major influence on human health, from getting a good night’s sleep to improving chemotherapy treatments. Partch and other biological clock researchers hope that advancing our understanding of circadian rhythms will revolutionize medicine.

“There’s a growing awareness of the effect that time has on biology,” says Partch. “Understanding the environment that you live in and that you create for yourself can have a really powerful effect.”
