Honeybees are good at maths, but it was thought they could only count to four. That is, unless you present them with a task in which they are punished with a bitter-tasting drink for getting it wrong.
It's unlikely that all species of bees will go extinct anytime soon – but current losses could still have a terrible impact on food supplies and ecosystems.
We're left wondering whether we as humans are so very special after all – that perhaps the ability to learn mathematics could be universal.
Wild bees pollinate trees and shrubs that feed and shelter wildlife, provide flood control, prevent soil erosion and help regulate the climate.
Bee brains contain less than one million neurons. Despite this, new research shows the honeybee can use symbols to perform basic maths, including addition and subtraction.
Bees need flowers to live, and we need bees to pollinate our crops. Understanding bee vision can help us better support our buzzy friends and the critical pollination services they provide.
Remote sensors allowed us to observe the in-hive activities of honeybees, which could be key to keeping bee colonies worldwide healthy.
You have to draw an ethical line somewhere so if you were vegan, would you still eat avocados?
All too often the media buzz is centred around the managed honeybee, at the expense of other wild bee species.
Pollination by commercially raised bees is important to a variety of crops but none more than California almonds. In turn, beekeepers depend on them.
US farmers are planting more and more acres with seeds coated with neonicotinoid pesticides. An ecologist explains why this approach is overkill and may be doing more harm than good.
The Romans may not have had a symbol for zero, but bees understand what it means beyond just the simple assumption "there's nothing there".
Many fruits, nuts and other crops rely on bees to pollinate their flowers at just the right time of year. Many farmers rent bees to get the job done at pollination time.
Honeybees are responsible for only a third of crop pollination in Britain.
We're in the middle of an Insectageddon. But a garden of native plants can help insects, as well as birds and other wildlife.
Hoverflies are helping spread disease among the already declining bee population.
Urban bees deal with what's known as "habitat patches," discontinuous patches of green like gardens, parks and ravines. Green roofs could offer relief to bees dealing with habitat fragmentation.
Bees need pollen to survive and grow, but not all plants can provide the right mix.
Bees and home security cameras use the same complex techniques to monitor their environments.
Garden pollinators can turn their noses up at the flowers human eyes find most beautiful.
