Maize is one of the world’s most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research, published Dec. 1 in Science, shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.

Jay Stachowicz, a professor in the Department of Evolution and Ecology, has been named the interim director of the Coastal and Marine Sciences Institute (CMSI). Stachowicz succeeds the institute’s founding director, Rick Grosberg, a distinguished professor emeritus of evolution and ecology who retired from the university earlier this year.

Each year, undergraduates in the College of Biological Sciences with exceptional academic performance are invited to join the Phi Sigma Honor Society’s Delta Gamma chapter. First started in 1984, the Gamma Delta chapter has long been a marker of excellence for UC Davis students.

Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis, shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands. The work was published Nov. 8 in Scientific Reports.

UC Davis junior Caroline Donohew watched the everyday power of biology in just five minutes during her summer session class at UC Davis’ Bodega Marine Laboratory, or BML, a coastal research and education facility about 100 miles west of campus. 

While observing a mussel’s muscle through a microscope, “I saw it create a byssal thread in real time,” said Donohew, who is from San Anselmo. “And it was just so cool.”
