Scarlet macaws are native to the tropics. So how'd they end up in New Mexico?

A Macaw Breeding Center Supplied Prehistoric Americans With Prized Plumage

This yet-undiscovered breeding center is likely one of the first instances of exotic animal husbandry in the region

Beer-drinking cups being excavated at Khani Masi held some of the earliest chemical evidence of beer. Researchers had to take extra precautions to avoid contaminating the cups with modern compounds.

Behind the Scenes With the Spacecraft That Will Soar Through the Sun’s Atmosphere

The probe, which launches Sunday, will attempt to solve enduring mysteries about the sun

The corn variety Sierra Mixe grows aerial roots that produce a sweet mucus that feeds bacteria. The bacteria, in turn, pull nitrogen out of the air and fertilize the corn. If scientists can breed this trait into conventional corn, it could lead to a revolution in agriculture.

The Corn of the Future Is Hundreds of Years Old and Makes Its Own Mucus

This rare variety of corn has evolved a way to make its own nitrogen, which could revolutionize farming

More like not-so-great white shark. Like today's sharks, prehistoric sharks sported a vast array of body sizes, shapes, and ornamentations.

Megalodon Wasn’t the Only Impressive Shark in the Prehistoric Seas

No longer thought of as “living fossils,” ancient sharks sported a crazy amount of variety

Darwin, described by caretakers as a bit "goofy," befriended even the Zoo's cassowary, widely considered one of the world's most dangerous birds.

The National Zoo’s Beloved, Aging Emu Has Died

Darwin delighted zoo patrons for 21 years with his clever antics and charisma

The Malama Kī Forest Reserve, seen from a helicopter, has been inundated with lava. What the lava hasn't covered, volcanic gases have browned, defoliated and suffocated.

Volcanic eruptions change the natural world in dramatic ways

Zebra finches fire up brain regions and vibrate their vocal cords in ways that mimic singing, even while asleep.

Zebra Finches Dream a Little Dream of Melody

Zebra finches flex their singing muscles while snoozing, as if they’re lip-syncing in their sleep—and scientists want to know why

Four Przewalski's horse foals—one filly and three colts—have been born at the Smithsonian Conservation Biology Institute since mid-March.

Gambel's Quail makes its home in high, dry parts of the Mojave Desert. But like many bird species, it's struggling against the effects of climate change.

Climate Change Is Taking Down Birds in the Mojave Desert

New findings suggest increasingly dry conditions have halved Mojave’s bird populations over the last century. It’s a warning for the desert — and the world

Birds don’t fly across wide Amazonian rivers like the Rio Negro.

How Amazon Rivers Play a Role in the Evolution of Birds

Rivers are natural boundaries for evolving populations. But scientists don’t agree whether they create new species or just help maintain them.

Deciding what, exactly, constitutes a wilderness in the ocean is not completely figured out, though some researchers are trying to find an answer.

Why the Ocean Needs Wilderness

A new study finds that only 13 percent of the ocean can be classified as “wilderness.” But what does this even mean?

Fears materialized when a series of deadly botulism cases struck unassuming consumers throughout the country.

The island dwarfism effect seems to have occurred independently in each population, thousands of years apart

When Bsal first arrived in the Netherlands, the pathogen wiped out 96 percent of the resident population of fire salamanders in a few years.

How American Scientists Are Planning to Thwart a Salamander Apocalypse

Yet another fungus threatens to decimate amphibians in North America, but this time, scientists stand ready

The Santa Monica State Beach is an allegory of North American consumerism. Every morning, cleaners collect chip bags, takeout containers, plastic straws, and more, hiding tonnes of trash from beachgoers who may never know the magnitude of the problem.

Are We Grooming Beaches to Death?

Urban beaches worldwide have less garbage than remote beaches, but less life too. The City of Santa Monica hopes to change the image of a clean beach.
