Jeffrey Groh examines an avocado plant at a greenhouse at UC Berkeley

Postdoctoral fellow Jeffrey Groh led a study on the genetic explanation of avocado pollination. All avocado trees are hermaphrodites, but until now, it was unclear how avocado flowers function as female in the morning and male in the afternoon (A-type plants), while B-type plants follow the opposite pattern.

North and South America weren't always connected, but their mammals still found a way to intermingle

Department of Integrative Biology - Thu, 07/30/2026 - 15:38

IB professor Jack Tseng, former IB undergrad Leah Kahn, former visiting postdoctoral scholar Adolfo Pacheco-Castro, and collaborators at the Natural History Museum of Los Angeles and the National Autonomous University of Mexico documented fossil evidence indicating that animals from different latitudes of North and South America intermingled before the formation of the Panamanian land bridge, which linked the two continents.

New fossils upend catastrophist narrative that flowering plants flourished only after dinosaur extinction

Department of Integrative Biology - Thu, 06/25/2026 - 14:27
Examples of seeds and fruits from the Dori’s Tuff flora of the Jose Creek Formation in New Mexico. The photos show tiny seeds (upper left) and a group of large fruits (right).

IB professor Cindy Looy, grad student Jaemin Lee, former doctoral student Dori Contreras, and former undergrad student James Saulsbury reported that Dori's Tuff flora contained large fruits from flowering trees, suggesting that animals were eating larger seeds produced by angiosperms 75 million years ago.

Aris and Lowet receive Jane Coffin Childs Fellowships

Department of Bioengineering - Thu, 06/25/2026 - 12:33
Congratulations to two postdoctoral scholars in BioE lab who have been named 2026 Jane Coffin Childs Fellows! The charitable fund supports brilliant postdoctoral fellows conducting fundamental research on cancer and human disease. Kevin Aris, PhD, works in Aaron Streets' lab on tools to measure DNA supercoiling in living cells, to build a genome-wide map of DNA shape. Adam Lowet, PhD. works with Michael Yartsev to explore the computational and biological mechanisms underlying social decision-making in the Egyptian fruit bat.

IB faculty and doctoral student receive W.M. Keck Foundation grant

Department of Integrative Biology - Wed, 06/17/2026 - 10:05
Peter Sudmant on the top half of the image and Michael Singer on the bottom half of the image

IB Professor Peter Sudmant, a genome scientist and expert in computational biology, and Ph.D. candidate Michael Singer are researching the "extreme" immune systems of bats through long-read sequencing which provides data for predicting and preventing future bat-borne viral transmission to human populations. The grant will support faculty and their graduate student collaborators to maintain progress on high-risk, high-impact work. Read the full story in Berkeley Inspire.
