Over hundreds of million years of evolution, ants have come up with some pretty smart solutions to problems of agriculture, navigation and architecture. People could learn a thing or two.
Bees that can adapt to the changing climate around us offer hope for more research and better policy and conservation efforts.
Seventy-two per cent of native bumblebee species in North America are cutting their winter hibernation short by timing their emergence to earlier spring onsets.

Honey bees, wild and native bees face threats from parasites, pesticides and habitat loss. Shorter winters, more extreme weather and more habitat destruction won’t help.
Spraying from either a ground-based vehicle or an airplane is a common method for applying pesticides.

Farmers who use little or no fertiliser can use ecological practices to increase their yields.
The new State of the Environment report shows Australia’s soil and the life it holds is in poor condition. We need to protect our underground biodiversity.

The iconic monarch butterfly has been added to the Red List of endangered species, but hasn’t received protection in the US yet. That’s not necessarily a bad thing.
Cowpea is a popular protein source in West Africa.
Cowpea is an important crop in Ghana. What will a genetically modified version mean for the country’s farmers?
Dozens of bed bugs and their eggs and fecal material on a metal bed frame.
Bed bugs are pretty much universally reviled. But a public health entomologist explains how – while potentially traumatizing to deal with – they aren’t likely to make you sick.

Cleaning up the Great Lakes was a big job when the US and Canada undertook it in 1972. Today it’s far more challenging.
BPA is an industrial chemical used to make hard, clear plastic known as polycarbonate. It’s also used in the lining of some cans. Many hard plastic bottles no longer contain BPA, and it’s illegal to sell baby bottles with BPA in Canada.

Studies suggest that seeds coated with neonicotinoid insecticides may harm nontarget insects, mammals and birds. In response, states are starting to restrict use of these products.
Mosquito eggs float on the surface of a pond. The insecticide Bti is used to kill mosquito larvae, but it could also harm frogs.
The insecticide Bti kills target organisms like mosquitoes and blackflies, but new research shows it may also have negative effects on non-target species like frogs.
