It's good to see the University of California's Office of the President award a three-year $900,000 grant to four UC Davis campuses to establish a network of bee researchers and engineers to strengthen honey bee health and crop pollination. 

The grant, titled "Strengthening Honey Bee Health and Crop Pollination to Safeguard Food Availability and Affordability," and headed by principal investigator Boris Baer, a UC Riverside professor of entomology, also includes Davis, San Diego and Merced campuses. “I'm very excited about so many different kinds of bee expertise joining forces through this project,” Baer said. 

Honey bees pollinate more than 80 agricultural crops, including almonds, apples, blueberries and cherries. The pollination services of these tiny agricultural workers account for about a third of the American diet. However, pesticide exposure, spread of parasites and pathogens, habitat destruction and environmental changes are challenging beekeepers, resulting in decreased pollination services and increased food prices.

The grant is an important one. Co-principal investigator Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, which operates the Harry H. Laidlaw Jr. Honey Bee Research Facility, says it well: "Most excitingly, this funding will not only support research that will help improve pollinator health so crucial for California's agriculture, but it will provide opportunities for training of students and postdoctoral scholars. Work focused on improving honey bee stocks via novel tools aligns well with ongoing work in the Niño lab and will further cement collaborations with beekeepers and growers.”  

Niño, who works closely with California beekeepers, launched and directs the California Master Beekeeper Program, which uses science-based information to educate stewards and ambassadors for honey bees and beekeeping.

Other co-principal investigators are James Nieh and Joshua Kohn of UC San Diego, and a trio from UC Riverside:  Kerry Mauck, Tsotras Vassilis, and Kim Hyoseung. At Merced, Marilia Palumbo Gaiarsa serves as a co-investigator.

The UC scientists plan a three-pronged approach to resolve the issue: develop better breeding programs, better medications and treatments, and better tools to monitor bee health in the hives. Small “listening and smelling” devices will be placed inside the hives to monitor bee health.

"Safeguarding honey bees and their pollination services requires beekeepers to be better able to manage the health and survival of colonies, which requires research into the causal factors and interactions affecting pollinator health, and the development and implementation of novel tools in close collaboration with industry partners. To do this, we will form a California wide, cross disciplinary research network and 

1. experimentally study the ecological and molecular factors and their interactions that affect honey bee health and their interactions to identify biomarkers of their health
2. use the knowledge gained to develop and deliver new, effective solutions for stakeholders, including remote sensing of bee health, a marker-assisted breeding program, and the development of novel medications,
3. build a research industry nexus to conduct collaborative research. We will also develop and deploy new extension and outreach modules that will be offered through UC Cooperative Extension statewide. We will support California beekeepers to build and maintain a sustainable and profitable beekeeping industry, which has implications for food security on a national level."

The co-principal investigators also noted in their grant proposal that "The current coronavirus pandemic and impending recession is putting more pressure on agriculture to provide sufficient and affordable food. Honey bees are key to such efforts, and supporting a California based beekeeping industry also decreases the state's dependence on managed pollination from elsewhere, thereby creating new jobs and income."

Funding also will help provide research opportunities for undergraduates, including underrepresented students, with the goal of ensuring that the pipeline of students who enter research, academia, industry, and multiple other professions reflects the diversity of the communities in which they learn and work.

This is all a win-win situation.

As Kohn said in a UC San Diego news release: “This network of bee researchers comprises a unique mixture of expertise that can apply highly multidisciplinary approaches to benefit the honey bee industry essential to the production of many of California's most economically important crops."

The news stories and social media comments about the Asian giant hornet detected last year in British Columbia and Washington state and labeled “the murder hornet,” are drawing the ire of entomologists throughout the world.

And well they should.

UC Davis wasp expert and researcher Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology, called the name "ridiculous" and said "it's no more likely to sting and kill a human than a honey bee." (See Bug Squad blog)

Kimsey, a two-term past president of the International Society of Hymenopterists, told us yesterday that “Actually it's less likely, as honey bee venom packs quite a punch and it is exclusively designed to defend against vertebrates."

“The colony everyone is hyperventilating over was actually found on Vancouver Island, British Columbia, last September when it was destroyed and then a single, dead hornet was found in December in Blaine, Wash.,” Kimsey said. “There is no evidence that there are any more hornets in the vicinity of Vancouver or anywhere else on the West Coast.”

A colony of the Asian giant hornet (AGH), Vespa mandarinia, was found and destroyed Sept. 18, 2019 in Nanaimo, Vancouver Island, and the single dead hornet was found Dec. 8, 2019 in Blaine.

These were the first detections of this species in North America, and no, the so-called "murder hornets" are not out to get us. They're not out to kill you. They're not taking over the world.  (Expect some upcoming horror movies, though!)

Twenty Asian giant hornet (AGH) specimens are housed in the Bohart Museum of Entomology, home of a global collection of nearly 8 million species. The largest AGH, a queen, measures about an inch and a half long, Kimsey said. She's never seen any larger than that.

Meanwhile, entomologists are bemoaning the name, "murder hornet" and the sensationalism and fear-mongering ensuing. Apparently the name originated with a Japanese researcher; out of the translation came "murder hornet."

“It's a bloody dumpster fire,” said entomology advocate, traveler and photographer Stephane De Greef, administrator of a newly created Facebook page, “Is This a Murder Hornet?”

“Some poorly-worded media reports about Asian giant hornets have triggered a veritable avalanche of nonsense online, but I can help set the record straight, wrote senior museum scientist and hymenopterist Douglas Yanega of UC Riverside Entomology Research Museum.

“One colony was found and exterminated in Nanaimo on Vancouver Island in September of 2019, with a few sightings associated,” Yanega wrote. “One wasp believed to be from that colony was found--dead--on the U.S. side of the border near Nanaimo in December. Right now, all the authorities are doing is asking people to keep their eyes peeled JUST IN CASE there were queens that escaped the destruction of the Nanaimo nest, and established their own nests nearby. I was one of the authorities brought in to consult on this case, and to my knowledge there have not been any sightings in 2020 that would suggest the eradication attempt was unsuccessful. Put bluntly, as far as we know, there are no Asian giant hornets alive in either the U.S. or Canada as of 2020, and if there are, then they would be in the immediate vicinity of Vancouver Island (about a 50 mile radius or so).”

Want to know more about them? Read the fact sheet published by Washington State University Extension. It's the work of the husband-wife team of Susan Cobey, bee breeder-geneticist and Timothy Lawrence, county director of Island County Extension (both formerly of UC Davis), and also Mike Jensen, county director of Pend Oreille. (See https://bit.ly/2SA3TxS)

“It is critical that we identify, trap, and attempt to eliminate this new pest before it becomes established and widespread,” they wrote. “Attempts to contain the spread and eradication of this invasive insect will be most effective in trapping queens during early spring before their nests become established. Finding the nests can be a bit of a challenge. Their nests are typically in the ground though they can also be found under overhangs and within wall voids. The AGH is a strong flier and often will fly up and away and have an extensive flight range. Thus tracking can be difficult.”

They advise residents to “proceed with extreme caution and contact WSDA immediately. Do not try to exterminate the nest yourself.”

The sensationalism on the media is a concern, said Lawrence, "but...we need to find out just how extensive this infestation is."

Facebook users are posting images of so-called Asian giant hornets that are actually such species as cicada killers, European hornets, southern yellow jacket queens, sawflies, hoverflies, a beetle, and even a moth.

“Yes, it is possible this species could establish,” wrote Sloan Tomlinson, a parasitoid wasp specialist and educator. “Has it yet? No. Until concrete evidence is presented about any further establishment by this species, it's simply conjecture. Additionally, even IF this species is established, their infamy is overhyped and sensationalized. In Japan they do indeed kill around 30 people a year. Around 40 people are killed annually in the US by domestic dogs.”

Doctoral candidate and researcher Ellie Field of Iowa State University wrote on Facebook that “the murder hornet articles are making the rounds quickly and they seem to be doing more harm than good. Yes, it is awesome to track insect populations (particularly staying watchful for non-native and potentially invasive species). But no, the Asian giant hornet (Vespa mandarinia) is not going to destroy America. The one nest and individual that was found around Vancouver last year was destroyed, and this doesn't indicate any establishment. Introduction events happen all the time, all across the world! That region should continue to keep a watchful eye, but for everyone else this is not going to be relevant. There is no invasion, just a small possibility that some may have overwintered in that area.”

Those unsure about insect identification can email an image to Lynn Kimsey at lskimsey@ucdavis.edu or contact the Entomological Society of America at https://www.entsoc.org/ or https://bit.ly/2W2jRmi.

Entomologists also identify insects on such Facebook pages as “Insect Identification,” “Entomology,” and “Spider and Insect Enthusiast.”  

Meanwhile, they're trying to douse the "bloody dumpster fires."

(Update: UC Davis distinguished professor Walter Leal, who studied and worked in Japan,  asked a Japanese friend today about the origin of "murder hornet":  The Asian giant hornet, Vespa mandarinia, is called “Kiiro Suzume Bachi (キイロスズメバチ)” in Japanese. It injects its venoms, sometimes inducing severe anaphylaxis. The article in BBC introduced Asian giant hornet, Vespa mandarinia as “murder hornet” is at https://www.bbc.com/news/52533585. The translation, Leal says, is incorrect. Kiiro means yellow.  Says Leal: "Almost 100 percent certain that the translation is not 'killer' but 'yellow.' His friend confirmed.)

Solar energy should not only be used to benefit global sustainability, but to protect our global ecological systems, including climate, air quality, water and wildlife, says an international team of 16 researchers, including several UC Davis scientists, in a newly published study in the journal Nature.

That includes pollinator habitat.

In their paper, “Techno-Ecological Synergies of Solar Energy for Global Sustainability,” published today (July 9), the researchers propose a “techno–ecological synergy (TES), a framework for engineering mutually beneficial relationships between technological and ecological systems, as an approach to augment the sustainability of solar energy across a diverse suite of recipient environments, including land, food, water, and built-up systems.” 

They provided “a conceptual model and framework to describe 16 TES of solar energy and characterize 20 potential techno–ecological synergistic outcomes of their use.” 

The paper offers what is considered the most complete list yet of the advantages of solar energy. "The study also marks the launch of a partnership between the Center for Biological Diversity and UC Davis to advance a Wild Energy future, which emphasizes the potential of solar energy systems to benefit not only humans, but the entire planet," according to a UC Davis news release.

Despite solar energy's growing penetration in the global marketplace, “rarely discussed is an expansion of solar energy engineering principles beyond process and enterprise to account for both economic and ecological systems, including ecosystem goods and services,” wrote lead author Rebecca Hernandez of the UC Davis Department of Land, Air and Water Resources and the Wild Energy Initiative of the John Muir Institute of the Environment, UC Davis. She considers the first step in creating a wild-energy future is "understanding the true value of solar."

The researchers defined TES “as a systems-based approach to sustainable development emphasizing synergistic outcomes across technological and ecological boundaries…solar energy combined with TES may prove a promising solution for avoiding unintended consequences of a rapid renewable energy transition on nature by mitigating global change-type problems.”

Co-author and entomologist Leslie Saul-Gershenz, associate director of research for the Wild Energy Initiative, John Muir Institute of the Environment, said it is imperative to protect our ecological system, which includes pollinators and their required resources. Among them: nest sites, and pollen and nectar resources.

“Native pollinators face global pressure from many sources of habitat alteration, pesticide use, invasive non-native plants, and climate change,” said Saul-Gershenz, who received her doctorate in entomology from UC Davis. “We are proposing land sparing priorities in undisturbed ecosystems, such as arid lands in the Mojave and Sonoran deserts, which sustain some of the highest native pollinator species diversity in the United States.  We add the valuation of these pollinators as essential resources into the calculation when selecting sites to deliver renewable energy goals to achieve true tech-ecological synergy and global sustainability.”

Solar cells, called photovoltaic (PV) solar energy, convert sunlight directly into electricity. For example, in Minnesota and Vermont, land adjacent to croplands is developed with PV solar energy, the authors noted. The low-growing flowering plants for native and managed pollinators help increase agricultural yields, reduce management (that is, mowing) costs, and confer the opportunity to produce honey and other honey-based commodities.

The researchers concluded that “achieving a rapid transition from fossil fuels to renewable energy sources on planet Earth to support human activities, in a manner benign to Earth's life support systems, is arguably the grandest challenge facing civilization today. The consequences of climate and other types of global environmental change are a cautionary flag against the extrapolation of past energy decisions.”

Hernandez initiated the research and led the conceptual design and writing of the manuscript  All authors contributed to further content development and drafting of the manuscript. The team also included researchers from UC Berkeley, UC Riverside and UC San Diego, as well as scientists from Lancaster University in the United Kingdom; U.S. Fish and Wildlife Services, Sacramento; Center for Biological Services, Tucson, Ariz.; Université de Thiès, Senegal; Centers for Pollinators in Energy, Fresh Energy, St. Paul, Minn.; National Renewable Energy Laboratory, Golden, Co.; and Renewable Energy and Environmental Finance Group, Wells Fargo, San Francisco.

Look for more research on solar energy!

"Solar energy is the fastest-growing source of power worldwide," according to the UC Davis news release. "In 2019, solar is expected to provide more than 30 percent of all new U.S. electric capacity. According to the International Energy Agency, solar energy could become the largest electricity source by 2050. Solar has many advantages beyond providing power, particularly when built to maximize social, technological and environmental benefits."

Looking back on 2018, Bruce Hammock, distinguished professor at the University of California, treasures the memories of the Hammock lab reunion, when 100 scientists from 10 different countries gathered to honor his work, reunite, collaborate and reminisce.

The distinguished professor, known for his expertise in chemistry, toxicology, biochemistry and entomology, meshes all four sciences in his 50-year research on acute and neuropathic pain in humans and companion animals. It all began with his basic research on how caterpillars become butterflies, research that led to key discoveries about chronic pain.

But back to the reunion.

illed as “Biochemistry and Society: Celebrating the Career of Professor Bruce Hammock,” the three-day event drew Hammock lab alumni from throughout the United States, as well as Egypt, Spain, China, Australia, New Zealand, Germany, Sweden, Canada and the Czech Republic.

“It was really special and I will treasure that weekend always,” said Hammock, who trained scientists at UC Riverside for five years before joining the UC Davis faculty in 1980. He currently holds a joint appointment with the UC Davis Department of Entomology and Nematology and the UC Davis Comprehensive Cancer Center. He has directed the UC Davis Superfund Program, funded by the National Institutes of Health's National Institute of Environmental Health (NIH/NIEHS), for 31 years.

Hammock's colleagues, and former postdoctoral fellows, graduate and undergraduate students and visiting scholars arrived at the lab reunion with their spouses--as well as their scientific posters for display and discussion. The posters covered everything from ground-breaking research in prestigious journals to a humorous look at his annual water balloon battles in front of Briggs Hall.

The scientists dined at the UC Davis Conference Center, the Buehler Alumni Center and the Stonegate Country Club; shared months, years and decades of memories; and toasted, roasted and gifted their mentor. Hammock, in turn, toasted, roasted and gifted them.

“We had a blast,” recalled organizer Shirley Gee, a former research toxicologist and manager of the Hammock lab for 31 years. She retired in June 2016 after 40 years of service with the university.

“I have had a vision of this event to honor Bruce for many years now, and it was such a thrill to see it come together,” she said. “Reconnecting in person with all the alumni and their families was more rewarding than I could have imagined, but even more importantly was the thrill of watching alumni reconnect with each other!  There were a lot of tears in the house.  Many people I think were surprised by how the years melted away when they began reacquainting.  I think that speaks to the environment that Bruce created that led to many strong personal and professional bonds.” 

Gee credited her seven-member committee—former Hammock students Keith Wing, Jim Ottea, Tom Sparks, Babak Borhan, Qing Li; postdoctoral fellow and “academic grandson” Kin Sing Stephen Lee, a former student of Babak Borhan; and colleague Sarjeet Gill, now a distinguished professor at UC Riverside, with greatly contributing to the success of the one-of-a-kind celebration.

As graduate students, and  Hammock and Gill worked together in the John Casida lab at UC Berkeley and later in Larry Gilbert's lab where they co-discovered the enzyme, soluble epoxide hydrolase.   Hammock remembers researching juvenile hormones and what's involved in "how caterpillars became butterflies."

Hammock has studied the enzyme system and its inhibitors ever since. His  lab has generated more than 80 patents, 300 postdoctoral fellows, and more than 65 graduates, who now hold positions of distinction in academia, industry and government. He recently formed a Davis-based company, EicOsis, to develop an orally active non-addictive drug for inflammatory and neuropathic pain for human beings and companion animals. Human clinical trials are scheduled to begin in 2019. Several seed-fund grants and a NIH/NINDS (National Institute of Neurological Disorders and Stroke) Blueprint Development Grant support EicOsis.

Hammock, described at the lab reunion as a “genius,” collaborates with scientists worldwide in what's been described as “unprecedented research with a multidisciplinary, integrated approach to research focused on insect biology, mammalian enzymology, and analytical chemistry.” He has authored more than 1000 publications on a wide range of topics in entomology, biochemistry, analytical and environmental chemistry in high quality journals, and has been cited more than 54,000 times. In the epoxide hydrolase field, the Hammock laboratory has published almost 900 peer-reviewed papers. 

Tom Sparks, who was Hammock's first graduate student at UC Riverside, chronicled Hammock's career and recalled humorous anecdotes from his early professorship at UC Riverside. A former professor at Louisiana State University, and now a research fellow in Discovery Research at Dow AgroSciences (now Corteva Agriscience, Indianapolis, Sparks praised Hammock's intellect and curiosity. “For Bruce, it was all about the journey, looking around and operative at the interface between entomology, biochemistry and chemistry.”

Gill,  along with University of Utah emeritus professor Glenn Prestwich and UC Davis research scientist Karen Wagner also delivered presentations, fondly recalling their shared time and science with Hammock.

Keith Wing, who was Hammock's second graduate student at UC Riverside/Davis, served as emcee at the lab reunion. A former senior research associate at DuPont and Rohm and Haas and current consultant, Wing said “Bruce has inspired many hundreds of developing scientists. For myself and many others, he was able to see what we could become as scientists and social contributors before we could see it ourselves."

Others commented that they learned this from Hammock: “We explore the unexpected and get to do things that don't work” and “Design things to fail; when they don't fail follow along.”

Hammock, the crowd agreed, seems to follow baseball legend Yogi Berra's sage advice: “If you come to a fork in the road, take it.”

Gill praised Hammock's “impact on human health, environmental health” as well as his love of the outdoors—from kayaking to mountain climbing.

Numerous alumni lauded Hammock's sense of humor. One scientist quoted Albert Einstein as saying “Creativity is intelligence having fun” and added “Bruce is always having fun.”

Among the other comments:

• “I never heard him speak a cross word.”
• "He treats everyone with respect.”
• "Bruce loves science and he loves people.”
• "He never heard a crazy idea.”
• "What Bruce does—he delivers the future.”
• "Bruce has a lot of determination and can approach difficult problems from multiple angles.”
• "Bruce values strong relationships with friends he has made over the years”

 A native of Little Rock, Ark., Hammock received his bachelor of science degree, magna cum laude, in 1969 from Louisiana State University, Baton Rouge, where he majored in entomology and minored in zoology and chemistry. Then it was off to UC Berkeley, for his doctorate in entomology/toxicology in 1973, and postdoctoral fellowship.

It was at UC Berkeley where he met and married his wife, Lassie, who had just entered the doctoral program in plant physiology. They married in 1972 and then “the Army called me up,” Hammock remembers.

Hammock served as a public health medical officer/first lieutenant with the U.S. Army Academy of Health Science in San Antonio, Texas; and then did more postdoctoral research at the Rockefeller Foundation, Department of Biology, Northwestern University, Evanston. Ill.

Hammock then joined the faculty of the Division of Toxicology and Physiology, UC Riverside Department of Entomology in 1975 before heading for UC Davis in 1980 to accept a joint-faculty appointment in toxicology and entomology.

Bruce and Lassie reared three children: Tom, Bruce and Frances. “Frances and her husband, Adrian, teach math at UC San Diego; Bruce is on the UC Davis School of Veterinary Medicine faculty; and Tom, a graduate of the American Film Institute Conservatory, makes movies,” Hammock said, adding that he and Lassie appeared in one of the movies  that Tom directed: "The Last Survivors."

Highly honored by his peers, Hammock is a fellow of the National Academy of Inventors, which honors academic invention and encourages translations of inventions to benefit society. He is a member of the U.S. National Academy of Sciences, a fellow of the Entomological Society of America, and the recipient of scores of awards, including the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics; and the first McGiff Memorial Awardee in Lipid Biochemistry.

Hammock told the crowd at the reunion that he began his career studying insect science but switched to human research after encountering “all the suffering involved in acute and neuropathic pain.”

His insect science research centered around how a key enzyme, epoxide hydrolase, degrades a caterpillar's juvenile hormone, leading to metamorphosis from the larval stage to the adult insect. He then wondered "Does the enzyme occur in plants? Does it occur in mammals?" It does, and particularly as a soluble epoxide hydrolase in mammals.

“It is always important to realize that the most significant translational science we do in the university is fundamental science,” said Hammock. “The extreme and poorly treated pain that I observed as a medical officer in a burn clinic in the Army, is a major driver for me to translate this knowledge to help patients with severe pain.”

And it all began with him asking how caterpillars turn into butterflies.

"Science is full of surprises," the distinguished UC Davis professor said. "We need to remember that the concept, the clinical target, and even the chemical structure came from asking how caterpillars turn into butterflies."
