K-State entomologist to lead $1M effort to expand bee project

The National Science Foundation has awarded more than $1 million to researchers at three U.S. universities to further advance a Kansas State University project that hopes to conserve one of nature’s most important pollinators.

K-State entomologist Brian Spiesman launched the website BeeMachine.ai and a mobile app in 2020 to help track trends in bee populations across the world.

Spiesman said a recent update substantially improves users’ ability to contribute to the citizen science effort and communicate their sightings. The update was funded by a K-State Game-changing Research Initiation Program for exploratory research, or GRIPex, award for nearly $250,000. The NSF grant will allow the researchers to continue that work.

“We are now able to identify 354 types of bees from around the world, and this number will continue to grow as we develop our image data set with the NSF project to include more types of bees,” Spiesman said.

There are an estimated 4,000 bee species in North America alone and more than 20,000 worldwide. According to Spiesman, BeeMachine.ai currently contains tens of thousands of images of bees submitted from mobile app and website users.

Bees are considered one of the world’s most vital pollinators. The Food and Agriculture Organization of the United Nations reports that nearly three-quarters of the world’s food crops depend, at least in part, on pollination. The organization also reports that pollination has the potential to increase agricultural yields and quality worldwide.

Among the hundreds of foods that rely on pollination during development are apples, bananas, blueberries, strawberries, peaches, potatoes, vanilla, almonds, chocolate, coffee, canola, tomatoes, grapes, avocados and many more.

Spiesman added that animals also pollinate close to 90% of the world’s flowering plant species.

“It is important to remember that there are more than 20,000 kinds of bees, and many of them are facing declines because of the interacting effects of habitat loss, climate change, overuse of pesticides, and invasive or noninvasive species,” Spiesman said. “This great diversity of bees is one of the reasons it is so important to be able to identify the different species so we can establish which are in decline and develop effective conservation strategies.”

INFO AND IMAGES NEEDED

Since the launch of BeeMachine.ai four years ago, 4,000 users have contributed more than 14,000 sightings from all continents except Antarctica. However, to fully unleash the power of artificial intelligence technology, more images and information are needed.

Spiesman said the NSF awarded K-State $372,442 to continue the work and add improvements.

“You improve artificial intelligence algorithms by adding more images, but image availability is the main limiting factor in developing reliable algorithms,” Spiesman said.

K-State has formed partnerships with the University of Kansas and the University of Wisconsin — who also received money from NSF — to photograph collections of pinned bees for improving AI algorithms. Spiesman said KU has more than 500,000 bee specimens that can be added to BeeMachine; Wisconsin has several thousand, as well.

“K-State will use NSF funds to support personnel who can conduct imaging, which will allow us to continue existing partnerships with other groups, such as USDA’s Agricultural Research Service in Logan, Utah, which holds more than 1 million bee specimens,” Spiesman said.

He added that the collections from the KU and Wisconsin are curated specimens.

“We know what species they are and just need to image them for training our models,” Spiesman said. “We hope to be able to add most of the 4,000 bee species in North America plus many other species in other parts of the world to our algorithm, and all of the more than 425 bee genera in the world.”

Currently, Spiesman said conservationists don’t have a full understanding of the extent to which bees and other critical insects are in decline, and why.

“We first need to understand the problem before we can take effective action,” he said. “This project will be important for empowering people with the ability to help us gather the kind of data we need to enact effective conservation.”

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts. Without bees, a large portion of the food we eat would not be available. Q2: What are the main threats to...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

German election: Climate and environment take a back seat When the coalition government comprising the center-left Social Democratic Party (SPD) , Greens and neoliberal Free Democratic Party (FDP) emerged after the last German federal election in the fall of 2021, then-incoming Chancellor Olaf Scholz (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor Robert Habeck from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right Christian Democratic Union (CDU) , Friedrich Merz ...
