The Mind

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.

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.

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

Do wild animals get PTSD? Scientists probe its evolutionary roots

Many creatures show lasting changes in behavior and physiology after a traumatic experience

Psychedelics open a new window on the mechanisms of perception

Some neuroscientists think psychedelic drugs and the hallucinations they induce could help reveal how the brain generates our perceptions of the world around us — and of ourselves

Out for blood in the search to stall aging

A gaggle of biotech start-ups are trying vastly different approaches to spin animal studies into the next big anti-aging therapy. It’s too early to know which, if any, will succeed.

Ah, wilderness! Is nature the tonic we’ve needed for pandemic malaise?

As Covid-19 descended across the world, people sought refuge in gardens, parks and the woods. But it’s hard to measure how being in nature affects our well-being — and how we can best reap its rewards.

Keys to successful aging

VIDEO: Watch a scientific exploration of why old age is often associated with high levels of emotional well-being, even as physiological and cognitive capacity declines

The puzzle of play

The purpose of play — for children, monkeys, rats or meerkats — has proved surprisingly hard to pin down. Scientists continue to toss around ideas.

Memory, the mystery

PODCAST: Just in the past half-century, our understanding of how exactly our brains remember has taken huge leaps. Amazingly, this is just the beginning. (Season 1/ Episode 4)

How researchers are making do in the time of Covid

The coronavirus pandemic has shuttered labs and sidelined scientists all over the world. Here’s a look at how some of them have coped.

The mysterious, multifaceted cerebellum

Once thought to merely coordinate movement, this region of the brain is proving to exert greater influence on cognition, emotion and other functions

Making and breaking connections in the brain

The links between nerve cells, called synapses, allow us to learn and adapt, and hold clues to conditions such as autism, schizophrenia and more

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

Sex strategies of the evolutionary kind

For women, a short-term fling may involve a quest for good genes or just a good time. It’s a puzzle for the researchers looking at how people choose mates.

Why speech is a human innovation

Many animals have the equipment for spoken language, but only people have all the right neural connections
