So-called gynandromorphs are rare, but they can teach us a lot about development and evolution

In a release the Zoo reported that last week: “Keepers noticed that Ambika’s right-front leg, which bore the brunt of her weight, developed a curve that weakened her ability to stand. Though she had some good days and some bad days, staff grew concerned when she chose not to explore her habitat."

As the pachyderms increasingly clash with farmers and villagers over disappearing land, scientists study the way the animals’ minds work

Vampire bats, a highly social species, will continue interacting with each other even when they're feeling sick.

When Illness Strikes, Vampire Bat Moms Will Still Socialize With Their Kids

Studying how bats behave when they’re feeling ill could help researchers better understand how pathogens move through close-knit populations

Zookeepers and Smithsonian scientists successfully transferred cheetah embryos, marking a major conservation milestone for the vulnerable species

Three Cassiopea, or upside-down jellyfish, seen from above in a lab at the Smithsonian’s National Museum of Natural History. The cloudy matter floating above and to the left of the jellyfish is a mucus that they exude.

These Jellyfish Don’t Need Tentacles to Deliver a Toxic Sting

Smithsonian scientists discovered that tiny ‘mucus grenades’ are responsible for a mysterious phenomenon known as ‘stinging water’

150-Year-Old Mummified Bee Nests Found in Panama City Cathedral

The nests, covered in gold leaf and paint, act as a time capsule for the surrounding environment circa 1870

Coyotes are about to enter South America, a move that could soon make the species, native to North America, one of the most widespread carnivores in the western hemisphere.

Coyotes Poised to Infiltrate South America

The crab-eating fox and the coyote may soon swap territories, initiating the first American cross-continental exchange in more than three million years

Humpback whales being tagged by researchers off the coast of Antarctica in 2018. The data gathered revealed that diet largely dictates a whales' maximum size.

Whales Are the Biggest Animals to Ever Exist—Why Aren’t They Bigger?

New research highlights the role diet plays in dictating a cetacean’s size

Reproductive biologist Pei-Chih Lee helped develop a new procedure to dehydrate and preserve samples of cat ovarian tissue without freezing.

Scientists Pumped Ovarian Tissue Full of Sugar and Microwaved It. Here’s Why

Though only tried in cat tissues so far, the technique could someday aid fertility preservation, wildlife conservation and more

A Savannah sparrow stands on a patch of melting snow in a warm-season grass field in Virginia.

Not All Birds Fly South for the Winter

Researchers in Virginia studied how mowing, burning or animal grazing helped or hindered birds that stayed home for the winter

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically edited H. charithonia wings have wider swathes of yellow.

What Butterflies’ Colorful Wing Patterns Can Teach Us About Evolution

Smithsonian scientists used genetically-engineered butterflies to learn that evolution can take a different path to achieve the same thing
