Postdoctoral fellow César Nufio and his colleagues (IB Professor Caroline Williams, Dr. Lauren Buckley, and Dr. Monica Sheffer) have shared a new study of Colorado grasshoppers that shows grasshoppers that overwinter as juveniles have a head start on those that emerge in the spring.

"Was the T. rex brightly colored with feathers? Did it run as fast as movies make it seem? How new discoveries challenge our long-held beliefs about the world of paleontology." Integrative Biology Professor Jack Tseng shares his expertise.

Professor Cindy Looy's research reveals that the Pacific Coast’s kelp forests, rich ecosystems supporting diverse marine life, originated over 32 million years ago, much earlier than previously believed. Read more in this article linked here.
 

In the La Brea Tar Pits, few of the recovered Saber Tooth Tiger skulls still have the sabers attached. But in the batch that had the sabers, a handful exhibited a peculiar feature: the tooth socket for the saber was occupied by two teeth, with the permanent tooth slotted into a groove in the baby tooth. Paleontologist Jack Tseng, Associate Professor in the Department of Integrative Biology, doesn’t think the double fangs were a fluke. Read more in this Berkeley news article linked here.

Congratulations to José Pablo Vázquez-Medina for his promotion to the rank of Associate Professor. The Vázquez-Medina lab studies mechanisms of adaptation to natural and anthropogenic stressors in marine mammals and pre-clinical models of disease at the molecular, cellular and organismal level.
 

Integrative Biology graduate student Robert Leija and the whole Professor George Brooks Lab make a discovery. The study was part of a larger NIH-funded study to determine how well people switch from fat to carbohydrate metabolism as they age. Read the Berkeley News Article.
 

Integrative Biology Professor Doris Bachtrog was elected to the American Academic of Arts & Sciences in 2024. She was elected in the Evolution and Ecology section of the Biological Sciences elected members.
 

A new study by IB researchers (Professor Cindy Looy, PhD alum Rosemary Romero, and BA alum Tony Huynh) and collaborators shows that kelp flourished off the Northwest Coast more than 32 million years ago, long before the appearance of modern groups of marine mammals, sea urchins, birds and bivalves that today call the forests home.
