The list of alleged ethical missteps by EPA Administrator Scott Pruitt just keeps growing longer, but they don't seem to be having any effect on his standing with President Trump.

Lava from Kilauea volcano has filled Kapoho Bay and inundated a section of coastline that was once covered with lush forest and dotted by homes.

The eruption of Kilauea on Hawaii's Big Island is causing local devastation, but it is an exciting research opportunity for volcanologists.

The spectacular lava fountains and fissures on Hawaii's Big Island are scaring the tourists away. That's a big problem for an island whose economy is heavily dependent on visitor dollars.

The evacuated housing development at Leilani Estates was built on the flank of the volcano. Some people wonder why anyone would ever live there. The answer? The homes are affordable.

Hawaii officials continue to warn the public about dangers from the active volcano on the Big Island, including the lava flowing toward a power plant. In the meantime, they are trying to reassure possible visitors that the tourism opportunities have not been affected.

Over 40 structures have been destroyed and thousands remain evacuated as the volcano erupts. Lava flows from dozens of fissures have reached the ocean, creating a dangerous phenomenon known as "laze."

Environmental Protection Agency chief Scott Pruitt often cites the need for "regulatory certainty." But even some supporters of his sweeping rollbacks say they're creating the opposite.

EPA chief Scott Pruitt is praised by industry and conservatives for his aggressive moves to roll back environmental regulations. But how much he's changed the department is debatable.

The EPA says it wants to only use research in which all data are publicly available. Scientists say this would hurt policy making on everything from air pollution to toxic waste and pesticides.

The National Park Service will increase entrance fees at 117 national parks by at least $5. The increases are far smaller than had previously been proposed by the Trump administration.

New money is going towards gun violence research, paving the way for new generation of data analysts, who have grown up in an era of mass shootings, to enter the field.

A day after a woman opened fire on the YouTube campus in San Bruno, Calif., questions are being asked about how the shooter got into the facility, and whether police were warned about her anger.

San Bruno Police Chief Ed Barberini says that one person is dead and multiple are wounded after a shooter opened fire at the HQ of Youtube around 12:45 local time.

Police have confirmed an active shooter at the Silicon Valley headquarters of YouTube. NPR's Mary Louise Kelly talks with NPR's Nate Rott, who has talked with hospitals in the area.

The EPA is rejecting landmark fuel efficiency rules for automobiles, a key part of President Obama's efforts to address climate change. The move could lead to another legal battle with California.

The Environmental Protection Agency appears set to weaken fuel efficiency standards. The move could lead to another legal battle with California.

Unbiased data about guns is hard to come by. A growing number of states are weighing whether to launch their own gun research initiatives to help fill the void left by federal cuts to such research.

The steady drop is expected to accelerate in coming years, threatening the much-lauded model through which the U.S. has paid for conservation.

For the first time since he was elected, President Trump is visiting California to review progress on border wall prototypes, address service personnel at a Marine base and attend a fundraiser in the Los Angeles area.
