Study reveals how contamination can increase within colonies. Inside a honeybee colony, worker bees act as living filters. They intercept much of the pesticide contamination entering the hive, helping shield the queen and the developing young she produces. But when exposure continues and that protective system begins to fail, the queen may redirect the chemical [...]

Veterinary students at the University of Georgia learned to care for honeybees, which are vital pollinators for U.S. agriculture. Between 2024 and 2025 more than half of the managed colonies in the U.S. have been lost.

Veterinarians are gingerly embracing the honeybee, a vital pollinator for agriculture but one that’s in increasing danger.

Bumble bees demonstrated an unexpected ability to solve a novel object-based challenge without training. A bee’s brain is smaller than a sesame seed, yet in a new experiment, some bumble bees appeared to solve a problem that required more than simple instinct. They had to move an object into position, climb onto it, and use [...]

Experts discuss the threat and how to escape aggressive bees. Hint: Don’t jump in water.

Despite having tiny brains, bumblebees have demonstrated a remarkable ability to socially learn how to use tools, solve simple puzzles, and cooperate to achieve a goal. It seems they can also solve object-manipulation tasks without any previous training, according to a new paper published in the journal Science. According to the authors, it's the first time this kind of spontaneous problem-solving has been demonstrated in an insect.

In 2024, Olli Loukola of the University of Finland co-authored a study demonstrating that bumblebees could cooperate to solve complex challenges. It's the kind of cognitive task scientists had previously only observed in large-brained mammals like humans and chimpanzees. Loukola et al. trained pairs of bees to push a Lego block to the middle of a mini-arena or push against a door at the end of a tunnel to get a reward.

The team noticed that the bees were more likely to engage in the tasks if their partners also participated, compared to untrained control groups. They concluded that bees can learn to solve novel cooperative tasks outside the hive and may even be intentionally working together, although the researchers cautioned that more detailed monitoring of the behavior was needed to fully understand the partners' roles.

New research suggests a widely used herbicide may have subtle but significant effects on honeybees. Growing flowering plants for pollinator gardens, farms, and home landscapes often requires herbicides to control weeds. Honeybees are naturally drawn to these areas and are essential for pollination. But researchers wanted to know what happens when bees are exposed to [...]
