How wind turbines could coexist peacefully with bats and birds

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

As the climate changes, plants must shift their ranges. But can they?

Lots of them depend on fruit-eating birds and mammals to spread their seeds. But it’s debatable whether the animals — many in trouble themselves — can disperse seeds far and fast enough to keep pace with a warming world.

Everyone should start counting spiders

Our collective arachnid aversion could be causing us to overlook something even scarier: Spiders may be disappearing.

Division of labor in ants, wasps, bees — and us

Social insects and humans share the trait of divvying up tasks, as do some fish. Researchers find that it emerges naturally, and it often doesn’t take a boss to keep things in order.

Evolution of the nervous system

COMIC: When, why and how did neurons first evolve? Scientists are piecing together the ancient story.

Do spiders dream? What about cuttlefish? Bearded dragons?

Researchers are finding signs of multiple phases of sleep all over the animal kingdom. The ‘active’ sleep phases look very much like REM.

The underappreciated benefits of wild bees

Native pollinators are key to both ecology and agriculture, but have yet to get their due

Conservation paleobiology: Eyeing the past to restore today’s ecosystems

Researchers use historic remnants like antlers, shells, teeth and pollen to learn how natural communities once worked. The clues serve as guides for restoration.

Charles Henry Turner’s insights into animal behavior were a century ahead of their time

Researchers are rediscovering the forgotten legacy of a pioneering Black scientist who conducted trailblazing research on the cognitive traits of bees, spiders and more

The extraordinary case of the ferocious female moles

Their genital anatomy, musculature and aggressiveness have made them a model for studying the phenomenon of female masculinization — and demonstrate that sometimes, it’s not easy to tell the difference between male and female

The fossil that launched a dinosaur revolution

PODCAST: Archaeopteryx forever changed our understanding of dinosaurs and the origin of birds, but it took a century after its discovery and a one-page paper to shift scientific consensus (Season 3, Episode 2)

Dealing with rats, and their health, in America’s ‘rattiest’ city

OPINION: A study in Chicago found that rodents surviving poisoning are more likely to carry disease. Good pest control needs to take such things into account.

Nature, nurture and randomness

OPINION: More than genes and upbringing determine animal personalities: There’s a good dose of chance in the mix, too.

A shocking number of birds are in trouble

Rich data on the global state of our feathered friends presents plenty of bad news — but also some bright spots. Researchers know better than ever how to help endangered birds, and there are notable bird conservation successes.

Get out in your yard and count bugs

OPINION: How worried should we be about insect declines? Community science is vital for gathering information about arthropods.

Mysteries of the poisonous amphibians

Many brightly colored frogs and salamanders have enough toxins in their skin to kill multiple people. How do they survive their own noxious weapons?

A warmer planet, less nutritious plants and … fewer grasshoppers?

Higher levels of carbon dioxide are changing micronutrients in grasses, trees and even kelp. What does that mean for animals higher up the food chain?

Zoos need to change

OPINION: To justify their existence, they must make conservation their top priority

Not enough fish in the sea

The scientist who found a way to tally up global catches is an ocean advocate and a vocal critic of industrial fisheries. Now we have a treaty for the high seas — but does it go far enough?

Animal personalities can trip up science, but there’s a solution

Individual behavior patterns may skew studies. A new approach called ‘STRANGE’ could help, by taking into account the habits, tendencies and life experiences of the creatures under scrutiny.
