Crows are believed to have intelligence on par with a seven-year-old child and demonstrate complex behaviors, from problem-solving with tools to recognizing human faces.

Nearly 5,500 crows died during four months in 1999 from West Nile in NYC

Subsequent testing made clear the disease at that point was 100% fatal to crows. From 1999 to 2004, millions of birds died as West Nile spread across North America, but the virus fortunately became less virulent as it moved westward.

How birds are becoming research assistants

Through the creation of tiny sensors easily placed on their bodies, birds have served as research assistants for various scientists. With untold numbers of birds sending back data, researchers have achieved greater insights in long obscure areas of meteorology, ecology, and more. For example, weather scientists use high-flying birds to outline the height of the planetary boundary layer, while conservationists track gulls to protect migrating whales. Learn more here.

Some animals may anchor their brain cells to specific landmarks to determine direction

In a study of bats exploring a new area, specific sets of "head direction cells" were seen becoming active based on bats' orientation when moving, and this activity became more coordinated over time. Researchers suspect, like humans, bats and other animals establish this sense of direction based on movement relative to known points of interest.

Exploring bird skulls

Birds inspire us to fly—but what about bird skulls? This collection of various birds' preserved skulls offers a peculiar "bird's-eye" view. See the many surprising shapes of beaks and eyeholes, from mockingbirds to turkeys, in this fascinating visual collection.

Why parrots can talk like humans

Birds are built with incredibly versatile tracheas that can mimic all kinds of sounds from their environment. For parrots, that includes human speech. This brief video explains why birds, who have such distinct anatomies from humans, are somehow able to talk like them, anyway.

Super recognizers may use specific facial features to commit faces to memory

Researchers believe that recognizing individuals seen only in passing, even decades later, is an ability of genetic origin and specific to facial recognition, rather than a result of better overall memory or perception. Applying eye tracking data from super recognizers to AI has led to improvements in facial recognition software.

The scarecrow isn't an effective tool for farms, but it is a potent symbol in horror

Scarecrows are no longer the best way for farmers to prevent birds from messing with their crops, but the humanlike figures are still found in horror movies. Folklorists say that's because they recall an agrarian past that makes modern viewers uneasy.

The dreaming brain, as understood by scientists

Technology has advanced to where the seemingly separate fields of psychology and neuroscience are asking the same questions about dreams, such as whether they're more closely related to perception or visualization. Some field-intersecting findings include research that shows people with impaired face perception don't dream of faces, those with brain legion-related cognition difficulties deal with similar issues in dreams, and children's dreams change in parallel to their cognitive development.

Why human brains were bigger 3,000 years ago

Our modern civilisation may be the most advanced to ever exist on Earth, but around 100 generations ago, our ancestors had brains that were larger than our own.

Can animals understand fairness?

Academics have long wondered if fairness is solely a concern of humans. In the largest meta-analysis to date, UC Berkeley researchers tested whether monkeys felt jealousy after receiving unequal rewards. The patterns showed low evidence for inequity aversion and instead frustration due to their expectations not being met by humans. These findings suggest that pursuing fairness and equality is uniquely human.

Some dinosaurs evolved night vision and acute hearing for nocturnal hunting

Paleontologists analyzed the fossilized eye and ear structures of 16 theropods, finding that some had owl-like hearing and huge pupils. These characteristics are consistent with modern-day nocturnal species, including nightjars and geckos.

Among the fascinating world of insects, leafcutter ants form some of the most complex and dynamic social ecosystems. All part of an effort to keep a colony alive, worker ants toil tirelessly, dragging bits of leaves and vegetation back to their...

Emotional crying is an important and cathartic process

Though babies don't initially produce tears when they cry, this podcast discusses how humans are hardwired to cry throughout life. Most crying research relies on self-reporting of crying and emotions. This podcast notes that there aren't neuroimaging studies of crying—they're quite expensive to complete. As a result, the brain precursors and processes during a bout of crying remain understudied.

Articulating weird memes

Some memes eschew established formats and references, creating new variants that resonate with scrollers through strange meta-jokes or compositions. This episode of this podcast, geared toward blind netizens, dives into some of the weird memes being shared online, such as one in which a pigeon sitting on a shoddy excuse for a nest, single egg forgotten, is meant to inspire comfort in those whose efforts have fallen short.

Dickens' pet inspired Edgar Allan Poe's 'The Raven'

Dickens had a pet raven named Grip and made him a character in the novel "Barnaby Rudge: a Tale of the Riots of Eighty." Poe reviewed the work and suggested the raven should play a bigger role. A few years later, he fixed the problem himself when he wrote his most famous poem, "The Raven." The bird is preserved at the Free Library Philadelphia.

Seven known types of coronaviruses have jumped from animals to humans

Coronaviruses, including SARS-CoV-2, belong to a large family of viruses characterized by their crown-like appearance under a microscope, due to spike proteins on their surface. While thousands are believed to exist in animals, only seven are known to have made the jump to humans.

Behind the fascinating disguising mechanism of camouflage

Camouflage—nature's master game of hide-and-seek—is more complex than simply how things look. The disguising process required millions of years of evolution that have programmed how our brains take shortcuts. Watch this video to see examples of camouflage and understand how we process it.

Fruit fly experiments show personality emerges, in part, from genetic factors

A 2025 study revealed that fruit flies exhibit unique behavioral preferences, akin to personalities, which could be artificially selected for when breeding to modify behavioral variability. This variability can be adaptive in unpredictable environments.

Grieving primate mothers will carry dead infant for long after death—and others will comfort her

An examination of infant corpse carrying practices among non-human primate mothers found that 40 species of primate mothers will carry around their dead infant for days, weeks, or even months. In some cases, a grieving primate's group members would provide grieving support—hugging or staying close to mothers who experienced a loss.

Two 100-year-old sisters share their tips for staying mentally sharp
