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...
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.
With recent advancements in portable, reliable, and low-cost scientific instruments, biological field research is flourishing. Now, a group of UC Berkeley undergraduates is newly equipped to investigate the natural world in real time with these new tools at their disposal.
From May 20-28, 2019, the Department of Integrative Biology’s inaugural Field Genomics summer course immersed first-year undergraduates in cutting-edge molecular biology techniques. The course provided thorough hands-on training in skills such as sample collection, nucleotide isolation, and portable nanopore DNA sequencing.
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.

Undergraduate Julia Anderson displays the subject of her senior research project: the skull of a giant vulture-like bird from the La Brea Tar Pits, which she’s analyzing and describing.
Alexander Stubbs of the University of California, Berkeley, and Fernando Montealegre-Z of the University of Lincoln in England studied a recording of the sounds made by diplomats and published by The Associated Press.

UC Berkeley doctoral student Emily King is studying the behavior of New Zealand mud snails to find a way to stop their infestation.
The tiny black dots on the soggy leaf that Emily King plucked out of Mount Diablo Creek the other day did not look very threatening, but the UC Berkeley biologist knows well how looks can be deceiving.
