It’s not just us: Other animals change their social habits in old age

In patterns that may sound familiar, long-term studies reveal what elderly deer, sheep and macaques are up to in their twilight years

Abracadabra! How magic can help us understand animal minds

By performing tricks for birds, monkeys and other creatures, researchers hope to learn how they perceive and think about their world

To pee or not to pee? That is a question for the bladder — and the brain

How do we sense the need to urinate? The basic urge is surprisingly complex and can go awry as we age.

Fit for a dog? The latest science on CBD for pets

Though studies are still mixed, and products often inconsistent, many scientists have hope that cannabidiol can help canines and other furry patients suffering from arthritis, allergies and anxiety

Indigenous languages are founts of environmental knowledge

Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity

How gut bacteria connect to Parkinson’s disease

Growing evidence suggests a link between the debilitating neurological illness and the microbes that live in our intestines. The vagus nerve may be a pathway.

The growing link between microbes, mood and mental health

New research suggests that to maintain a healthy brain, we should tend our gut microbiome. The best way to do that right now is not through pills and supplements, but better food.

Top science stories of 2023

Twelve standout news events and trends in a tumultuous year

Neanderthals: More knowable now than ever

They have held our fascination ever since we first identified their remains. Today, thanks to new artifacts and technologies, findings about our closest relatives are coming thick and fast.

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.

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

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 the brain calculates a quick escape

Whether fly or human, fleeing from danger is key to staying alive. Scientists are beginning to unravel the complex circuitry behind the split-second decision to beat a hasty retreat.

Color is in the eye, and brain, of the beholder

The way we see and describe hues varies widely for many reasons: from our individual eye structure, to how our brain processes images, to what language we speak, or even if we live near a body of water 

The vital crosstalk between breath and brain

The rhythm of respiration influences a wide range of behaviors, as well as cognition and emotion. Neuroscientists are piecing together how it all works.

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 awake ape: Why people sleep less than their primate relatives

Ancient humans may have evolved to slumber efficiently — and in a crowd

The science of dreams

PODCAST: We have thoughts, visions and feelings while we sleep, experiencing a virtual reality of sorts. But how and why does dreaming happen? Researchers bring us closer to understanding the work our brains do while our bodies rest. (Season 2/Episode 1)

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
