Swarms of mechanical bees may one day support natural pollination

Why scientists are making robot insects

Insects have much to teach us about flying, jumping, moving quickly, and more. So, roboticists are studying how insects do the ridiculous things they do, like walk on water or jump fifty times their body height, to inform their design and engineering of a new slate of robots: tiny ones. Learn the future of this type of robot with this fascinating video with insights into both insects and robots.

Efficiency of commercial honeybees may exacerbate population declines in native bees

Commercial beekeepers are increasingly breeding honeybees on public lands, raising concerns among environmentalists that they’ll compete with and introduce new diseases to already threatened native pollinator populations. However, native species alone are often unable to meet the pollination levels required to meet necessary crop yields.

Bees are crucial for pollination and food security

When animals and insects pick up the pollen of flowers and spread it, they allow plants, including many food crops, to reproduce. The most common pollinator is the bee, but bees are at risk from pollution and pesticides.

Human beekeeping has been traced back to 7000 BCE

Eighty-seven of the world's leading crops rely on pollination in some way, including 43 that are highly dependent or entirely reliant on it. Without pollinators, key foods such as apples, avocados, and almonds would likely become extinct, pushing entire ecosystems into collapse.

Millions of honeybees are hauled yearly across the US to help pollinate farms

As indigenous pollinator populations dwindle, farmers increasingly rely on commercial honeybees, which truckers often transport during cooler periods to prevent die-off from overheating. Pollinating all the almond trees in California requires 85% to 90% of all honeybees available to pollinate in the country.

Go inside a real beehive with this interactive

Beehives are where the magic honey-making happens, where thousands of honeybees beat their wings, throw up partially-digested nectar to further purify it into sugars, and make wax. The goings-on of a beehive—the name for a man-made habitat for...

Since 2019, a free-floating robotic system named Astrobee has helped astronauts with routine tasks on the International Space Station.

What is it like to be a bee?

Scientists have long known the intimate features of bee anatomy: six limbs, five eyes, lots of hair, a long, tasteless tube -like tongue, and wings that stroke close to 12,000 times a minute. But getting inside the mind or consciousness of a...

Contributing to one in every three bites of food consumed by humans, bees are a keystone species because of their essential role as pollinators of about 80% of all flowering plants worldwide.

About one-third of the world's food supply depends on pollinators like bees, butterflies, and bats to transfer pollen between flowers, which use bright colors, scents, and nectar to attract them.

Adding garden beds with blooming plants to an existing lawn can support bees

Blooming wildflowers, shrubs, and trees can provide the nectar and pollen these pollinators need but do not get from grass. Other tips include leaving patches of bare soil for ground-nesting bees to lay their eggs and filling birdbaths with large pebbles for them to land and drink from safely.

In Amsterdam, planting organic flowers has increased native bee diversity by 45%

The citywide effort is an example of rethinking conventional agricultural methods, which rely on monocropping and heavy chemical use. Cover crops—plants grown to suppress weeds, prevent erosion, and attract pollinators rather than to be harvested—have also shown environmental benefits, despite not being sold for profit.

Over 1,500 insect species pollinate plants in the UK

These insects—including bumblebees, moths, butterflies, and beetles—play a crucial role in the reproduction of flowering plants, also known as angiosperms. They do so by transferring pollen from the male reproductive organ—the anther—to the female one—the stigma—which enables the plant to produce fruit.

Native, wild bees are at much greater risk of extinction than honey bees

It is estimated that there are more honey bees, which often compete with native bees for resources, on the planet than at any point in human history. Meanwhile, 40% of invertebrate pollinator species, including wild bees and butterflies, face extinction in the coming decades.

The promise and peril of AI in agriculture

Robots. Drones. Artificial Intelligence. All three are touted as potential saviors for farmers, and are already being deployed on large farms, where they assist with such tasks as managing crops, milking cows, and helping farmers make decisions about their land. But agricultural AI could have disastrous, unintended consequences.

Coevolution of pollinators and flowering plants diversified both

The first pollinators were beetles, which consumed pollen before flowering plants existed. Over time, plants evolved to attract more insects and improve the uptake of pollen, while insects adapted their biology to enhance the capture of pollen, such as developing specialized mouthparts.

Pollinators help develop seeds by transferring pollen between flowering plants

As bees approach a bright, colorful flower for nectar, they bump into its stamen—the flower's male reproductive organ—and pollen gets stuck to the pollinator's body. This pollen can then be deposited on another flower's sticky pistil—the flower's female reproductive organ—which brings the pollen down to the ovule for fertilization.

Explore guides on pollinator-friendly plants native to where you live

Pollinators have co-evolved alongside specific plants from their natural habitat and see their populations increase in environments with these native flora. This collection offers recommendations for regional plants that can provide nectar and pollen, serve as host plants for caterpillars, and offer nest sites for specialist bees.

Bees are more likely to remember a flower if its nectar contains caffeine

Plants want pollinators to keep coming back, so the finding suggests that some plants, such as Citrus and Coffea species, have evolved to include caffeine in their nectar. Researchers suggest the findings could help develop methods to reinvigorate pollinator populations.

Bees evolved from meat-eating wasps that became vegetarian

After flowering plants first appeared approximately 140 million years ago, some wasp diets would have changed as they consumed pollen-coated insects that would visit these plants. Bees that branched from these wasp species also developed long tongues to slurp nectar and ultraviolet vision to identify flower patterns unseen by humans.

Some police departments in California have officers specialized in hive crime

The cost of a beehive climbed from about $35 in the early 2010s to $200 as of 2020, which has incentivized some to steal hives at night. These kidnappings led to the creation of dedicated task forces in the state, whose almond farms have created an extraordinary demand for pollinators.

Ordinary bee larvae can develop into queen bees upon being fed royal jelly

Royal jelly is a protein-rich, yellowish substance produced by worker bees in a honeybee hive. After three days, only a few continue receiving the jelly, which triggers the development of ovaries and other traits not found in workers. The first candidate to emerge becomes queen.

This six-minute video dives into the science of these nanorobots, which are smaller than blood cells. Applications of these nanobots could range from disease discovery and condition monitoring to tissue repair and artificial blood delivery.

Why physiology and genetics prevent king bees from existing

The mating process is fatal to male honey bees, as their endophallus detaches from their bodies and remains temporarily within the queen. Because fertilized honey bee eggs develop into female bees, if a male somehow did survive and become king, his line of succession would also abruptly end.

Agricultural intensification has accelerated declines in pollinator populations

The practice of using farmland more frequently to increase its yield increases the number of residual pesticides and decreases botanical biodiversity. These processes tend to decrease carrying capacity for pollinators by eliminating food sources and nesting habitats.

Why cows are loving their new robot caretakers

Autonomous robots are transforming dairy farming by letting cows choose when to be milked or cleaned. Dairy robot manufacturer Lely says this ability to decide reduces a cow's stress and increases milk production. The robot systems are costly, but are marketed as increasing efficiency for dairy farmers. And the cows appear to love them.

Appropriate timing of land management techniques can help support pollinators

The mowing, grazing, and burning practices used to maintain land should be tailored to the life cycles and needs of native pollinators, particularly those of rare or endangered species. For example, mowing is recommended in the fall or winter when flowers are not in bloom.

Spiders may manipulate captured male fireflies into mimicking female mating signals

Rather than killing a male firefly captured in its web, the Araneus ventricosus spider bites into it, which researchers believe injects a venom that disrupts normal flashing behavior and produces a form of mimicry to attract additional males. (Some readers may experience a paywall.)

US honeybee colony loss remains a concern, despite rebounding from the mid-2000s CCD

In the winter of 2006-07, worker honeybees began mysteriously disappearing from hives—a phenomenon known as colony collapse disorder—triggering the loss of as many as 90% of hives. The lack of dead bees found near hives and the declining prevalence of CCD since then have made finding a single cause challenging.

Less than 0.1% of the approximately 20,000 known bee species make honey

The majority of honeybee species originate in South and Southeast Asia, with the largest—Apis laboriosa—found almost exclusively in the Himalayas. The smallest is the black dwarf honeybee, Apis andreniformis, which inhabits tropical and subtropical regions of the continent.

Explore a collection of galleries of pollinators found in national parks

Many of the photographs were taken during pollinator inventories in national parks across the US. Although these inventories often focus on bees and butterflies, the collection also features beetles, moths, spiders, and birds that transfer pollen as they move from bloom to bloom.

The experiment opens the door to fabricating devices within cells to study and manipulate cellular functions.

Tracking butterfly migration via the pollen they collect

Trillions of insects migrate around the world each year, but many are too small to track with physical trackers, leaving their migratory routes a mystery. In recent years, scientists have utilized pollen grains collected from butterflies to analyze which plants that pollen originated from—providing substantial data to infer the insect's specific route. Research has shed light on many insects' migrations since, including the Painted Lady butterfly. Read more and see a map here.

Honeybees vomit nectar into one another's mouths to transform it into honey

Digestive enzymes break down long chains of complex sugars into simple monosaccharides, while the fanning of their wings helps honeybees evaporate water away. This process increases the acidity of the resulting honey, increasing its shelf life when sealed in beeswax.

In 2026, researchers at the University of Minnesota created the world's first synthetic cell—a cell made from non-living chemical components—that can eat, grow, divide, and compete with other cells for resources.
