The Science Behind Decorative Gourd Season

Gourds are the runts of their family of fruits, too tough and bitter to eat, but they remain one of the most popular crops of fall

To prevent animal species from going extinct, some ecologists suggest introducing them to urban environments to live alongside humans.

To Save Endangered Species, Should We Bring Them Into Our Cities?

Some ecologists believe our best chance to preserve biodiversity is to introduce non-native species to cities—but others warn of unintended consequences

Buffaloes at Rest recalls a time when bison were plentiful. When the print was created in 1911, only about 1,350 remained.

The Bison Returns to the Great American Plains

After years of fierce debate, the West’s greatest symbol will again roam the countryside

The sicyonia brevirostris, commonly known as a rock shrimp, is one of the several specimens photographed by Darryl Felder prior to preservation.

Hormone signals help ready worker mole-rats to treat pups as their own.

Eating the Queen’s Poop Makes Naked Mole-Rats Better Parents

Hive-minded naked mole-rats work together to care for the queen’s offspring, and eating her poop gives them hormones to boost nurturing instincts

Feast your eyes on the blind Somalian cavefish, which has—like mammals—mysteriously lost the ability to use light to fix damaged DNA.

Blind Cavefish Shed Light on the Dark Days of Mammalian Evolution

Like mammals, these cave-dwelling creatures have discarded a solar-powered system that repairs UV-damaged DNA

In the Pheidole genus of ants, some insects grow into soldiers with disproportionately large heads, while others grow to be smaller workers.

This “Useless” Organ Determines Which Ants Grow Into Large Soldiers

Rudimentary wing discs in ant larvae, which only grow to wings in queens, appear to influence growth into a soldier or worker

A study conducted during the 2017 total solar eclipse in North America found that bees remained active during the partial-eclipse phases both before and after the period of totality, but they essentially ceased flying during totality.

Busy Bees Take a Break During Total Solar Eclipses

The 2017 North American eclipse gave researchers an inside look at how bees respond to light—with the help of a few hundred elementary-schoolers

Dynamoterror was about 30 feet long, hunting prey during the Late Cretaceous.

Newly Discovered Tyrant Dinosaur Stalked Ancient New Mexico

The Dynamoterror, a relative of Tyrannosaurs rex, lived millions of years before other known species of tyrannosaur

The project aims to map the "Big Four," or the four most common venomous snakes in India—the spectacled cobra, saw-scaled viper, Russell’s viper (shown here) and common krait.

This App Is Saving Thousands of Snakes (and Humans) in India

The Big Four Mapping Project’s conservation tool helps prevent snakebites and the killing of common venomous species

“It is especially exciting to see Sukiri bonding with and successfully raising these cubs,” says the Zoo's cheetah biologist Adrienne Crosier.

New Cheetah Mom Earns High Marks Caring for Her Three New Smithsonian Cubs

Cubs born to Sukiri on September 22 are latest in the National Zoo’s efforts to diversify gene pool of captive born cheetahs

Ants and honey bees have been observed reproducing without males before, and now all-female termite colonies join the asexual group.

All-Female Termite Colonies Reproduce Without Male Input

These insects seem to have dispensed entirely of the need for males and their sperm

A record 105 tons of ivory was burned in Kenya in 2016, destroying tens of millions of dollars in illegal wildlife goods.

Rhino Horn and Tiger Wine: How the Illegal Wildlife Trade Is Growing Bolder

Wildlife author and journalist Rachel Nuwer discusses her new book Poached about one of the world’s fastest-growing contraband industries

By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or 'ecstasy,' scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.

Ecstasy Turns Antisocial Octopuses Into Lovestruck Cuddle Buddies—Just Like Us

The genetic and neurological similarities between octopuses and humans shed light on how creatures became social beings

A female snowy owl leaves her nest as a human approaches. This is her first line of defense to not draw attention to the nest location.

Why Is the Snowy Owl Disappearing?

These birds, once a feature of the far north as reliable as ice, are becoming less and less common

How Wireless Water-to-Air Communication Could Revolutionize Marine Research

Solving a longstanding puzzle, MIT researchers have developed a way of sending signals from underwater to airborne devices

The vibrant Baltimore Oriole can be found migrating throughout large portions of eastern and central North America.

Scientists Can Predict When Birds Will Migrate Up to a Week in Advance

A new forecasting model using years of bird migration data and weather radar could help us protect migrating birds from harm

New archeological findings suggest the Maya city state Copan dealt in a robust jaguar trade

Young grassland birds don't rush their final nest exit. They instead stick around as long as possible to gobble up as much food as they can stomach.

These Teen Birds Love Sleeping In, Too

A new study suggests young grassland songbirds postpone fledging in order to mooch off mom and dad as long as they can
