These Butterflies Evolved to Eat Poison. How Could That Have Happened?

Monarch butterflies eat only milkweed, a poisonous plant that should kill them. The butterflies thrive on it, even storing milkweed toxins in their bodies as a defense against hungry birds. For decades, scientists have marveled at this adaptation. On Thursday, a team of researchers announced they had pinpointed the key evolutionary steps that led to it...

IB graduate students traverse the globe for summer research projects

20190826_Mattina.pngFor the graduate students of Integrative Biology, the summer months bring a wealth of opportunities to embark on critical research projects and present their findings all over the world. Forty-four graduate students were able to carry out their field and laboratory research, thanks in part to three competitive awards sponsored by the Integrative Biology department: Dissertation Completion Award, Summer Grant, and Research Award. A broad range of projects are funded by these awards, from understanding UV radiation tolerance in desert mosses to studying how the shapes of turtle beaks relate to their diet and habitat over evolutionary time.

Women don beards to highlight gender bias in science

For many people, including women, the answer is yes, which spurred dozens of paleontologists around the world – all of them women – to glue on beards for photos now being exhibited at the Lawrence Hall of Science (LHS) at the University of California, Berkeley. The ironic message of the Bearded Lady Project is that, contrary to the persisting stereotype, you don’t have to be a man to love fieldwork and contribute to science; in fact: many field scientists are not.

Researchers Work to Reverse Cognitive Decline as People Age

Daniela Kaufer, professor of integrative biology at the University of California, Berkeley, shared progress toward addressing another cause of cognitive decline: dysfunction of the blood-brain barrier. The blood-brain barrier ordinarily protects the brain, but Kaufer’s work shows that when the barrier falters, itself a sign of aging, proteins can enter brain cells called astrocytes, which causes inflammation in the brain and leads to cognitive impairments.
