Five California sites made the top ten list for unhealthiest air, according to a new report

Officials have been working toward the designation for four years.

Oregon Is Now Home to the World's Largest Dark Sky Sanctuary

The Oregon Outback International Dark Sky Sanctuary covers 2.5 million acres in the southeastern part of the state

Humans produce about 400 million metric tons of plastic waste each year. Some chemicals in plastics have been linked to health problems for humans and animals.

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated, Report Finds

A new database catalogs 16,000 chemicals found in plastics and identifies more than 4,200 that are potentially hazardous to human health and the environment

Scientists conduct sampling at Crawford Lake in Ontario, Canada, in April 2023. Last summer, a working group chose the lake as a representative location for the influence of human activity on the planet due to the history recorded in its sediment.

Scientists Reject Proposal to Define the Anthropocene, a Geological Age Marked by Human Activity

Experts had suggested a new epoch started in the mid-20th century, but the recent vote demonstrates how tough it is to pinpoint when humans' impact on the planet began

Runit Dome in the Marshall Islands contains radioactive waste from U.S. activity during the Cold War. A new report says climate change may cause its contaminants to enter the environment.

Climate Change May Unearth Cold War-Era Nuclear Waste Stored by the U.S. in Other Countries

A new report finds that melting ice and rising sea levels could disturb radioactive contamination left over from American nuclear tests after World War II

Boiling and filtering tap water, researchers suggest, could reduce concentrations of microplastics by more than 80 percent.

Boiling Tap Water Could Help Remove 80 Percent of Its Microplastics, Study Suggests

Minerals in some tap water can capture tiny plastic particles when the water is boiled, making them easier to filter away, according to a new study

Natural gas flaring emits methane, a powerful greenhouse gas, into the atmosphere. The majority of atmospheric methane comes from human activity, with the agricultural sector and the oil and gas sector contributing the most from human activities.

New Satellite Will Track Methane Emissions From Space and Pinpoint Their Sources With A.I.

The mission, set to launch next month, comes as countries and fossil fuel companies pledge to reduce emissions of the powerful greenhouse gas

In a photo illustration, a hawk moth lands on a flower with an exhaust pipe polluting the interaction.

Air Pollution Makes Flowers Smell Less Appealing to Pollinators, Study Suggests

Nocturnal hawk moths are less likely to visit primroses in air polluted by nitrate radicals, which break down important wild fragrances, researchers find

A hermit crab wears the top of a broken bottle as a shell.

Hermit Crabs Are Using Trash as Shells Across the World, Scientists Find

Researchers analyzed photographs of the crustaceans online, identifying nearly 400 examples of artificial shells, which were often plastic bottle caps

When researchers reviewed footage of flying insects, they saw that the bugs tilted their backs toward the source of artificial light.

Why Are Flying Insects 'Attracted' to Lights? Scientists May Finally Have an Answer

Moths and other insects might turn their backs toward the brightest source of light around—which has historically been the sky—to determine which way is up and which is down, according to a new paper

Plastics break down over time into micro- and nanosized particles that litter our water and air.

One Liter of Bottled Water May Contain 240,000 Tiny Plastic Fragments

A new technique reveals that the liquid may contain 10 to 1000 times more plastic pieces than previously thought

COP28 president Sultan Ahmed Al Jaber and others applaud after nations adopted the first climate deal calling for a transition away from fossil fuels. A lead negotiator for 39 small island nations noted that the group was not in the room when the final agreement was reached.

Nations Agree to 'Transition Away From Fossil Fuels' in Landmark Climate Deal

The agreement, which ended the COP28 climate conference, is not legally binding, but it's the first to explicitly call for moving away from fossil fuels

An oil platform in the Gulf of Mexico. Officials spotted an oil slick three to four miles wide off the coast of Louisiana last Thursday.

Oil Spill Dumps as Much as 1.1 Million Gallons Into Gulf of Mexico, Raising Concerns About Wildlife

The U.S. Coast Guard is still searching for the specific source of the leak, which occurred last week

Astronauts Jasmin Moghbeli and Loral O’Hara were performing routine maintenance during a spacewalk outside the ISS when they lost the tool bag.

Astronauts Lost a Tool Bag During a Spacewalk—and You Can See It Floating From Earth

The bag slipped away while Jasmin Moghbeli and Loral O’Hara were performing routine maintenance on the International Space Station

Artist John Akomfrah Is Having a Moment

The works of the recently knighted filmmaker address contemporary issues in two different Smithsonian museums

California condors are attracted to shiny things and sometimes ingest wrappers, coins and padlock keys.

'Love Locks' at the Grand Canyon Could Be Harming Endangered California Condors

Park service officials urged visitors to stop attaching padlocks to fences and throwing keys into the canyon below, where the birds could eat them

Could this innovation provide a solution to one of our era’s biggest scourges?

Scientists Have Created Synthetic Sponges That Soak Up Microplastics

Made from starch and gelatin, the biodegradable sponges remove as much as 90 percent of microplastics in tap water and seawater

In 1997, an uncrewed ship collided with Russia's Mir Space Station, causing damage to Mir's solar array panel. As the number of human-made objects in space grows, the risk of collisions in Earth orbit increases.

In a First, the FCC Fines a Satellite Company for Abandoning Space Debris

The television provider DISH failed to remove a retired satellite far enough from its previous orbit, according to a statement from the commission
