Climate change is causing more severe flooding around the country, and a disproportionate number of Native American communities are on the front lines.

When harvests are bad, Native Americans in the region may go without rice for the year. And there have been a lot of bad years lately, as climate change causes more frequent and severe rainstorms.

How much damage a bullet does when fired at the human body hinges on physics. Our latest "Let's Talk" video shows and explains why certain types of ammunition cause greater havoc than others.

Twitter's stock tumbled 20 percent on Friday, despite the company's growing revenue. It mirrored Facebook's sharp drop earlier in the week, as investors worry that social media growth may be ebbing.

Multiple nuclear power facilities in Europe have reduced their electricity production because seawater, which is used to keep the reactors cool, has been warmer than usual.

The Internet relies on a network of cables, many buried underground along U.S. coastlines. A new analysis finds sea level rise could put thousands of miles of cable underwater in the next 15 years.

The agency's next acting chief has drawn praise as a capable administrator. But critics still say the transition from Scott Pruitt is a bit like "going from a train wreck to a house on fire."

More than 50 years after the federal government forced hundreds of Alaska Natives into boarding schools, their descendants are haunted by — and trying to overcome —residual trauma.

For more than 150 years, scientists have known that levees increase flood risk on the Mississippi River. That hasn't stopped local officials from building up levees in response to more severe floods.

Modern birds are dinosaurs without toothy jaws, and with bigger brains. Newly published research fills in some of the missing links in their evolution.

Each night, the organisms gather in a "vertical stampede" to feed at the ocean's surface. Research suggests the columns of swimming animals can create large downward jets that help churn the waters.

The EPA says the San Jacinto Waste Pits near Houston no longer needs Scott Pruitt's personal attention due to progress on a remediation plan. But the site is still years away from being cleaned up.
