A bumblebee’s brain is smaller than a sesame seed. But it can still accomplish quite a bit.
“You don’t need a big brain to learn well,” said Felicity Muth, an assistant professor in the Department of Neurobiology, Physiology and Behavior and a National Geographic Explorer who studies cognition in bees and other animals. “Bumblebees are capable of many of the same cognitive feats as many vertebrates.”
The University of California, Davis, is awarding over $480,000 to help scientists advance compelling research and innovations toward commercial applications through the Science Translation and Innovative Research (STAIR™) proof-of-concept grant program. The program plays an important role in helping campus innovators bridge the early-stage hurdle of access to funding during one of the most challenging phases in new technology development.
Researchers in the College of Biological Sciences have received a grant to study the role of the cerebellum in autism. “We need a more holistic understanding of the brain circuits that drive this disorder,” says Alex Nord, an associate professor of neurobiology, physiology and behavior (NPB), and a researcher at the Center for Neuroscience (CNS). “The cerebellum is a key component that has been largely overlooked until recently.”
When it comes to brain anatomy, the thalamus occupies a humble position. It sits at the top of our brainstem — an apparent vestige of our reptilian past — and is dwarfed by the massive, wrinkled cerebral cortex, which sits above it. The cortex is often credited as the throne of human intellect. But a team of researchers across the country, with UC Davis led by W. Martin Usrey, sees the thalamus as a critical coordinator of our thoughts and perceptions – and pivotal in human disease.
In the first part of the UC Davis Emeriti spring celebration, one of the most distinguished professors of the UC Davis emeriti family, Barbara A. Horwitz, was honored for more than five decades of service as a Professor of Neurobiology, Physiology, and Behavior within the College of Biological Sciences.
Kept secret until the day of the event because she dislikes the spotlight, the surprise homage included anecdotes from various colleagues, including Chancellor Gary May.
UC Davis molecular exercise physiologist Keith Baar spoke with UC Davis Health about how our body responds to physical activity and why intense exercise is better for your heart than walking more steps.
Wilsaan Joiner, a professor in the Department of Neurobiology, Physiology and Behavior, was among this year’s cohort of Chancellor’s Fellows.
“Our newest fellows represent the very best of UC Davis and I congratulate them,” Chancellor Gary S. May said in announcing the new fellows. “The knowledge, expertise and excellence these faculty demonstrate across a range of disciplines positively impacts our university’s mission of research, teaching and public service.”
Despite their small size, dragonflies are arguably one of the most impressive predators in the animal kingdom. According to Rachel Crane, a biologist at the University of California Davis, dragonflies often catch up to 95% of the prey they go after, a rate she described as “wildly high compared to where most predators are.”
More incredible still, this prey capture all happens in midair.
“Dragonflies are doing these really, really fast, high-speed aerial captures,” said Crane.
