Thanks to the ubiquity of electric light, less and less of the planet falls genuinely into darkness any more.

How Cities and Lights Drive the Evolution of Life

Urbanization and the spread of artificial light are transforming all of earth’s species, bringing about a host of unintended consequences

Paired Images of Melting Glaciers and Flooding Wetlands Tell the Story of Global Climate Change

Photographer Tina Freeman’s exhibition ‘Lamentations’ at the New Orleans Museum of Art juxtaposes two different environments

Female wasp of the newly described species Idris elba (holotype specimen).

Tiny Parasitic Wasp Named After Idris Elba Hijacks Stink Bug Eggs

The wasp genus Idris had only been known to infest spider eggs, until now

An ice patch nearing complete melt in northern Mongolia's Ulaan Taiga Special Protected Area, 2018.

Archaeologists Race to Preserve Artifacts as the Ice Melts in Mongolia

Disappearing patches of ice unleash new artifacts for discovery, but many could quickly degrade exposed to the elements

Scientists Around the World Declare ‘Climate Emergency’

More than 11,000 signatories to a new research paper argue that we need new ways to measure the impacts of a changing climate on human society

This high-precision GPS station is in the Ford Range of Marie Byrd Land, Antarctica. It is part of the Polar Earth Observing Network (POLENET), which collects GPS and seismic measurements to understand ice sheet behavior. It’s one example of the varied data that scientists are gleaning from GPS instruments.

Five Things You Probably Didn’t Know GPS Could Do

Scientists use the navigation system to measure and monitor many aspects of our planet

Collections at the Smithsonian's National Museum of Natural History are filled with all sorts of eerie specimens.

Check out some of the spookiest (read: coolest) items in the National Museum of Natural History’s collections.

Understanding plankton is essential to studying how ocean life is sustained.

This Device Has Been Measuring the Ocean’s Plankton Since the 1930s

Largely unchanged since it was invented, the Continuous Plankton Recorder collects plankton as it is towed behind a ship

CGI rendering of ancient Loxolophus mammal taken from the PBS NOVA special, Rise of the Mammals. In this recreation, Loxolophus scavenges for food in the palm dominated forests found within the first 300,000 years after the dinosaur extinction.

Fossil Site Reveals How Mammals Thrived After the Death of the Dinosaurs

Recent discoveries highlight how mammals lived before and after the asteroid impact that triggered the world’s fifth mass extinction

Photosynthesis evolved some 2.5 billion years ago, transforming life on Earth.

This Type of Algae Absorbs More Light for Photosynthesis Than Other Plants

Though evolutionary mergers between cells, some algae have developed the ability to convert a wider spectrum of light energy into sugars

By collecting images and GPS data from citizen divers, scientists can get a better sense of the health of the entire Great Barrier Reef.

Massive Citizen Science Effort Seeks to Survey the Entire Great Barrier Reef

Only about 1,000 of 3,000 individual reefs have been documented, but the Great Reef Census hopes to fill in the gaps

"An important first step is understanding how tropical forests worldwide, climate, and the food and other products that we consume are all interconnected on the global scale. Collectively we can have a real impact," says forest ecologist Kristina Anderson-Teixeira.

Yes, Tropical Forests Tragically Burned This Summer, but Here’s What You Can Do

Fires stoked worldwide anxiety, but Smithsonian forest ecologist Kristina Anderson-Teixeira offers a few practices for making a difference

Climate change is driving a surge in wildfires, and it’s only going to get worse.

This Gel Could Prevent Wildfires

Developed by Stanford researchers, the nontoxic, biodegradable gel can be sprayed on vegetation as a long-term fire retardant

The Global Change Environmental Research Wetland spans 173 acres in Edgewater, Maryland.

Marshes Grow Stronger When Faced With Increased Carbon Dioxide

Marsh plants respond to increased CO2 by growing many small stems, creating a denser wetland that may protect against sea level rise

In this agricultural revolution, there are plenty of mind-blowing devices to awe and excite.

Five Roles Robots Will Play in the Future of Farming

From picking fruit to pulling weeds, robotics are bringing precision farming to life

Three green sea turtles, Chelonia mydas, on a coral reef, Heron Island, Great Barrier Reef, Australia.

Coral Reefs Face the Dual Threats of Ocean Acidification and Erosion

As coral tissues die off, the exposed calcified skeleton becomes vulnerable to organisms that eat away at the dying reefs

One of the Dinizia excelsa or angelim vermelho trees, which can grow over 80 meters. The tallest, as measured by satellite, towered 88.5 meters above the forest floor.

Researchers Discover the Tallest Known Tree in the Amazon

Satellite images and a trek into the rainforest reveal a group of trees over 80 meters, or about 260 feet, and one as tall as 88.5 meters
