Extra “eyes” on top of bee heads help them see colours the same way under all light conditions. And it’s an approach that could help us design better cameras.

Two large-scale studies confirm that neonicotinoid pesticides can harm bees. But the effects vary widely in different countries, suggesting that calls for a world ban would be premature.

Beekeeping cannot depend on a single forage source. This makes the business of ensuring bees have what they need to stay healthy a precarious business.
It’s a decade since US beekeepers first noticed that their bees were mysteriously dying. Now we know much more about Colony Collapse Disorder, raising hopes that we can turn bees’ fortunes around.

Bees and other pollinating insects are under stress worldwide. Research in South Texas shows that simple steps like planting wildflowers near fields can help pollinators and boost farmers’ profits.
Honey bees, which pollinate many valuable crops, are threatened by parasites, pesticides and development. But selective breeding, more benign pesticides and better nutrition could help turn the tide.
Honey bees are in decline and the current method of keeping them can be disruptive to a colony. But new designs allow beekeepers to monitor a hive remotely, even sniff out disease and pests.
Elephant numbers are increasing in parts of sub-Saharan Africa. Their search for food is leading them into conflict with farmers living adjacent to game parks. Bees could prove to be the answer to the problem.
To understand why insects sting and why the stings of such tiny animals hurt so much, we first needed a way to measure the pain they cause. So I created a sting pain index.
