Trees were already known for cooling and cleaning the air of cities. A Europe-wide, participative science project shows how much their density matters for urban biodiversity.
Feeding insects instead of grain to animals is an inexpensive, sustainable way to increase the world food supply. An animal scientist explains what’s involved in developing insect feed for cattle.
Mosquitoes are commonplace in summer but where do they go once the weather cools? They don’t completely disappear but find fascinating ways to survive the winter.
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.
Fungi underpin life on Earth, but are far less well catalogued and understood than animals and plants. Three scientists call for including fungi in conservation strategies and environmental laws.
More carbon dioxide in the air doesn’t necessarily mean more growth for trees, and the increasing risk of wildfires and drought has major consequences, as an interactive map shows.
A new ‘protein roadmap’ produced by CSIRO reveals foods set to fill fridges by 2030 as health, environmental and ethical concerns push consumers away from meat.
Insects such as ants and beetles use ingenious processes in their brains to work out how far they’ve travelled and in what direction - we’ve now discovered how they remember their way home.
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.
