Animals

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.

How animals follow their nose

It’s not easy to find the source of a swirling scent plume. Scientists are using experiments and simulations to uncover the varied strategies that animals employ.

How lunar cycles guide the spawning of corals, worms and more

Many sea creatures release eggs and sperm into the water on just the right nights of the month. Researchers are starting to understand the biological rhythms that sync them to phases of the moon.

Mistletoes in a warming world

Can the famous parasitic plants help animals to survive climate change, or will they be killed off by extreme weather?

City birds are changing their tune

Several species of urban-dwelling birds have modified their songs in response to human-generated noise

Cultural transmission makes animals flexible, but vulnerable

From monkeys washing potatoes to cockatoos raiding trash cans, socially spread behaviors allow creatures to adapt more rapidly to changing environments than conventional evolution would allow. But the traits are also more easily lost.

The cultural lives of birds

VIDEO: Culture was once thought to be uniquely human, but scientists are finding evidence that many birds are also cultural creatures. What does avian culture look like? And why does it matter?

Wild robots: Five ways scientists are using robotics to study animal behavior

Biomimetic bots can teach researchers a lot about how creatures interact in the natural world

Spiders are much smarter than you think

Cognition researchers are discovering surprising capabilities among a group of itsy-bitsy arachnids

Protecting great apes from the unknown effects of Covid-19

Humans can transmit many diseases to chimps, orangutans and their kin. People who study and care for the creatures are taking lockdown-style measures to limit the risk.

Collective behavior: How animals work together

Studies of birds, fish and ants reveal the hidden ways groups coordinate movement, which might influence engineers designing drone armadas and efficient information flow

How bats keep viruses at bay

Bats cope with myriad viruses, including the one causing Covid-19, with few ill effects. Scientists are probing their immune systems to fathom how they do it. The answers might help infected people, too.

How humans shift fish evolution | Things to Know

VIDEO: By targeting larger individuals, intense fishing may lead to a fishery dominated by the small

The human hand in fish evolution

Fishery practices that go for the big ones may be counterproductive when mostly the small survive

An amphibious rescue mission

On the edge of extinction, rare frogs and toads need more than a little love to reproduce. High-tech help, from IVF to hormone therapy, may save them.

From tiger scat to DNA to — hopefully — survival

Researchers dig out the elusive cats’ genetic material where they can, to guide efforts at conservation and diversity

At San Diego’s Frozen Zoo, a chance for animal immortality

The cryobank is a rich source of genetic knowledge of hundreds of creatures. It may one day be used to bring endangered species back from the brink and deepen the gene pool of wild populations.

Marine wildlife is starting to suffocate

Global warming and agricultural runoff have driven the loss of oxygen in oceans around the world, with looming ecological consequences.

There goes the night

Artificial lights spell darker times for much of the planet’s wildlife — but it doesn’t have to be that way
