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.”

Atmospheric Rivers Spur High-Tide Floods on U.S. West Coast

Atmospheric rivers are narrow bands of moisture that travel across the lower troposphere, generally at the leading edges of massive low-pressure systems. At their peak, they can carry as much water through the sky as the Amazon River does on land. They unleash intense winds and heavy rain as they surge across the Pacific Ocean, eventually making landfall on the U.S. West Coast, contributing to many high-tide flooding events. However, the detailed relationship between atmospheric rivers and coastal high-tide flooding has not been well described.

In new research that will be presented on 17 December at AGU’s Fall Meeting 2021, scientists revealed how atmospheric rivers affected many high-tide flooding events on the U.S. Pacific coast over the past 4 decades. The team determined that depending on the location, anywhere from 10% to 63% of coastal high tide flood events observed from 1980 to 2016 occurred in confluence with atmospheric river events. Pacific Northwest sites experienced more high-tide floods and atmospheric river events overall, with the exception of more secluded Puget Sound sites.
