"Karl von Frisch referred to the waggle dance as the 'magic well' for the insights that it provides not only on honey bees, but on the general cognitive complexity that social insects are capable of," Nieh writes in his abstract. "New research demonstrates that the neurotransmitter, dopamine, the 'pleasure molecule' plays a similar hedonic role in honey bees as it does in many vertebrates, regulating the perception of danger and the anticipation of food rewards as revealed in the excitatory waggle dance and the associated, inhibitory stop signal. I will also discuss new data showing that the honey bee waggle dance is partially learned and has elements that may be culturally transmitted. Together, these findings, demonstrate that the waggle dance can teach us a great deal about shared cognitive mechanisms and the importance of social learning across taxa."
In an article titled "Unlocking Secrets of the Honeybee Dance Language--Bees Learn and Culturally Transmit Their Communication Skills," and published March 9, 2023 in The Conversation, Nieh described the waggle dance as "one of the most complicated examples of nonhuman communication. They can tell each other were to find resources such as food, water, or nest sites with a physical 'waggle dance.' this dance conveys the This dance conveys the direction, distance and quality of a resource to the bee's nestmates."
Nieh related exactly how the bees perform the waggle dance. "Essentially, the dancer points recruits in the correct direction and tells them how far to go by repeatedly circling around in a figure eight pattern centered around a waggle run, in which the bee waggles its abdomen as it moves forward. Dancers are pursued by potential recruits, bees that closely follow the dancer, to learn where to go to find the communicated resource."
"Longer waggle runs communicate greater distances," Nieh wrote, "and the waggle angle communicates direction. For higher-quality resources such as sweeter nectar, dancers repeat the waggle run more times and race back faster after each waggle run."
Nieh noted that "The Greek historian Herodotus reported over 2,000 years ago on a misguided forbidden experiment in which two children were prevented from hearing human speech so that a king could discover the true, unlearned language of human beings.
"Scientists now know that human language requires social learning and interaction with other people, a property shared with multiple animal languages. But why should humans and other animals need to learn a language instead of being born with this knowledge, like many other animal species?"
Nieh went on to point out that "This question fascinates me and my colleagues and is the basis for our recent paper published in the journal Science. As a biologist, I have spent decades studying honeybee communication and how it may have evolved."
Nieh received his bachelor's degree from Harvard University in 1991 and his doctorate from Cornell University in 1997. He completed a postdoctoral fellowship funded by NSF-NAT0 (National Science Foundation, North Atlantic Treaty Organization) at the University of Würzburg, Germany. He served as a Harvard Junior Fellow from 1998-2000

Bee scientist James Nieh, a UC San Diego professor in the Section of Ecology, Behavior and Evolution, Division of Biological Sciences, will present the first fall quarter seminar hosted by UC Davis Department of Entomology and Nematology.
Nieh will speak on "Animal Information Warfare: How Sophisticated Communications May Arise from the Race to Find an Advantage in a Deadly Game Between Honey Bees and Their Predators" at 4:10 p.m., Wednesday, Sept. 25 in 122 Briggs Hall. Brian Johnson, associate professor of entomology, is the host.
"In addition to the classical arm race that has evolved between predators and prey, information races also occur, which can lead to the evolution of sophisticated animal communication," Nieh says in his abstract. "Such information can shape the food web and contribute to the evolution of remarkable communication strategies, including eavesdropping, referential signaling and communication within and between species, including between predators and prey."
"I focus on the world of information exchange (acoustic, olfactory and visual) that has co-evolved between Asian honey bees (Apis cerana, A. florea, and A. dorsata) and their predators, the Asian hornets (Vespa velutina and V. mandarinia)," Nieh says. "I will explore how and why such information races occur through the remarkable examples provided by these high social insects."
He presented a TED talk on "Bees and Us: an Ancient and Future Symbiosis" in July 2019.
A native of Taiwan, Nieh grew up in Southern California and received his bachelor's degree in organismic and evolutionary biology in 1991 from Harvard University, Cambridge, and his doctorate in neurobiology and behavior from Cornell University, Ithaca, N.Y., in 1997. He subsequently received an NSF-NATO postdoctoral fellowship to study at the University of Würzburg in German. A Harvard junior fellowship followed.
Nieh joined the faculty of the Section of Ecology, Behavior and Evolution in 1997 as an assistant professor, advancing to associate professor in 2007 and professor in 2009. He served as vice chair of the section from 2009 to 2014, and as chair from 2014 to 2017.
His latest co-authored research, published in the journal Chemosphere in 2019, is titled Combined Nutritional Stress and a New Systemic Pesticide (flupyradifurone, Sivanto®) Reduce Bee Survival, Food Consumption, Flight Success, and Thermoregulation.
