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

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.

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.

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.

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.

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.

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...

Swarms of mechanical bees may one day support natural pollination

Engineers are racing to create tiny robot bees that can be programmed to mimic natural bee behavior, helping in specific scenarios such as indoor farming and space agriculture. Battery life challenges may be solved by having these robots accompanied by a nearby "mother" drone power supply.

What's so special about Mayan bees and their honey?

Melipona honey was utilized by the ancient Maya and produced by stingless bees located in Mexico's Yucatan peninsula. With a history dating over three millennia, this honey was traditionally used for medicinal purposes due to its high fructose content and antioxidant properties. Unlike regular honey, Melipona honey is less prone to crystallization and has a distinctive watery texture. Learn more about the honey here.

Can butterflies remember being caterpillars?

All holomatabolous insects like butterflies, bees, and moths undergo complete metamorphosis via a pupal stage. Inside the pupa, the insect breaks down into a goop of the basic elements of life like amino acids and proteins, out of which the adult stage of the insect grows. Despite this radical transformation, scientists theorize some of these insects retain what they call memories of their pre-pupa stage. Watch this video to learn more.

Some female fireflies mimic the signals of other species to lure in and eat them

The genus Photuris does not produce its own defensive pheromones to ward off predators, so it has developed mimicry to attract males of firefly species that do. Unsuspecting males are consumed after these chemicals—lucibufagins—are extracted.

Women are born with all the eggs they will ever produce in their lifetime

Girls are born with an estimated 1 million to 2 million eggs in their bodies, but around 10,000 die monthly before puberty. Scientists have not yet figured out why there's such an excessive number of eggs prior to menstruation, but they've calculated that there are roughly 300,000 to 400,000 eggs left at puberty.

One jellyfish species is biologically immortal

Turritopsis dohrnii is a type of jellyfish that can revert back to a juvenile stage after reaching sexual maturity, theoretically allowing it to stay alive for good. But that's a tough sell in a world full of predators. See this list of some of the longest-living species on Earth.

Sleep deprivation leads to buildup of danger molecules in the gut

Fruit flies genetically engineered to be awake for as long as they live tend to live half as long as their well-rested brethren. Analysis shows these modified flies suffer from a buildup of DNA-destroying reactive oxygen species in their guts. When enabled to sleep, the flies live as long as their counterparts.

Allergies occur when our immune system mistakenly considers a substance a threat

Immunoglobulin E antibodies, or IgE antibodies, may bind to an allergen, effectively labeling it as a threat. That triggers a cascade of actions in the body, including the release of histamine, which causes the characteristic itching and hives of allergies. Sometimes a cooked version of an allergen—like a cooked carrot—may look different enough from its raw form to the immune system that antibodies ignore it, and no allergic response takes place.

Eggshell color doesn't indicate taste or superiority

Brown, white, and blue eggs taste and cook identically. Despite popular notions that brown eggs are superior, the shell color reflects the genetics of the hen alone. What actually determines egg quality is freshness and the diet of the hen (where grass and leafy greens lead to denser yolks). And freshness can go both ways: older eggs peel more easily than fresh ones.

About two-thirds of humans lose their ability to produce lactase after weaning

Lactase is an enzyme that digests lactose—a sugar in milk and dairy products. While genetics strongly determines lactase persistence, factors like famine, disease exposure, and gut bacteria also influence symptoms and evolution.

Rare Jurassic-era insect found outside Arkansas Walmart

An entomologist on his way to buy milk sighted a giant lacewing, a rare insect not seen in the US for fifty years. The species has been present on earth for at least 160 million years, but has become incredibly rare in North America.

Random lasers can be created from biomaterials, such as peanuts and birch leaves

Rather than creating a narrow beam of light via amplification in an optical cavity, the random laser produces a red glow by scattering photons created in the natural pores of a peanut kernel after it has been injected with a solution of light-generating carbon dots derived from birch leaves.

Bone marrow generates roughly 500 billion new blood cells each day

Some of our bones are stuffed to the brim with a fatty, jam-like substance called marrow. Bone marrow comes in yellow and red, with the latter responsible for producing new blood cells, and has become critical in treating diseases like leukemia.

The first line of 'immortal' human cells, which can divide indefinitely and are used in scientific research, was nonconsensually taken from a Black woman.

Two Lyme disease vaccines were in development in 2026

As of early 2026, there was no vaccine for Lyme disease available. One candidate vaccine, VLA15, was in later-stage clinical trials. Another designed to provide seasonal protection was licensed to a pharmaceutical company in 2025, and was planned for human clinical trials.

Hookworm infection, though risky, may help fight certain autoimmune conditions by tamping down the immune system's inflammatory response.

Plant hormones and growth regulators guide growth stages and responses in plants

Plants naturally produce hormones like auxin and gibberellins, while humans apply synthetic or extracted growth regulators to control plant development. These substances influence processes like flowering, root growth, dormancy, and ripening—even in very small doses.

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.
