Toxins from the Colorado River toad have been ingested by some for their psychedelic and medicinal effects.

A Modified Psychedelic Toad Toxin Reduces Signs of Depression and Anxiety in Mice, Study Suggests

Colorado River toads produce a psychoactive toxin that some have claimed has medical benefits. The new research suggests these benefits could be achieved without hallucinations

Male belugas were more likely than females to change the shape of their melons, or foreheads.

Belugas May Communicate by Changing the Shape of Their Squishy Foreheads

Scientists documented five different melon shapes among the marine mammals living in captivity: push, flat, lift, shake and press

When attacked by a predator, the reptiles can play dead with convincing detail, employing blood and feces for the show

The Maya played games like pok-a-tok, in which players hit a rubber ball through a stone circle such as this one in the ancient city of Chichen Itza.

Hallucinogenic Plant Unearthed Beneath an Ancient Maya Ball Court

Researchers have found evidence of a nearly 2,000-year-old ceremonial offering at the site in present-day Mexico

Sperm whales communicate by making clicks.

Scientists Discover a 'Phonetic Alphabet' Used by Sperm Whales, Moving One Step Closer to Decoding Their Chatter

Researchers used artificial intelligence to spot patterns in recordings of the marine mammals' vocalizations, uncovering the "building blocks of whale language"

Memorable, large images and scenes are associated with a longer perception of time, a new study suggests.

Are Days Passing Too Quickly? Memorable Experiences Might Help Dilate Your Sense of Time, Research Suggests

How we process time is linked to things we see, according to a new study, which found memorable, non-cluttered imagery can make moments seem to last longer

An MRI of a brain of a person with Alzheimer's disease. A new study suggests having two copies of a genetic variant called APOE4 is a cause of the disease, not just a risk factor for it.

Almost All People With Two Copies of This Genetic Variant Develop Signs of Alzheimer's Disease, Study Finds

The research focused on a variant called APOE4 and largely looked at people of European ancestry—risk levels are different for other groups, the authors say

Bumblebees, on the whole, are better adapted for cooler temperatures than for heat—one species, Bombus polaris, even lives in the Arctic.

Bumblebee Nests May Be Overheating With Rising Global Temperatures, Study Finds

Across various species and regions, bumblebee nests thrive between 82 and 89.6 degrees Fahrenheit—and climate change could make it harder to find habitats in that range

Shanidar Z likely stood 5 feet tall and was around 40 years old when she died.
