A scientist discovers how some spiders go undercover as a less delicious species to evade predators.

It's a dog eat dog world out there in nature. One way not to get eaten is to look like something else that's not tasty. Now scientists have discovered a spider that fools predators by not only looking like a nasty ant, but actually walking like one.

A team of scientists and economists claims they've come up with the most thorough analysis of the cost of climate change in the U.S. Most of the country will suffer economic loss in addition to higher mortality from heat waves and loss of agriculture productivity by 2100. But like all predictions far into the future, this one has a wide range of outcomes and could be overshadowed by new technology still to be invented.

Scientists and economists predict what parts of the U.S. may get hit hardest by climate change. A new study goes county by county to gauge the potential cost of global warming.

Eggs evolved over 300 million years ago and now come in all kinds of shapes, from Tic Tacs to teardrops to pingpong balls. After studying some 50,000 eggs, a team of researchers thinks it knows why.

Scientists who found the fossils believe they are the remains of five people and far older than all previous finds. But how do the remains really fit into the bushy family tree of modern humans?

President Trump played to his base, ignored the advice of scientists, industry titans and world leaders and pulled the U.S. out of the Paris climate agreement.

President Trump announced on Thursday that the U.S. will leave the Paris climate deal. They are many things that could be affected by that decision, we explain.

President Trump announced Thursday the U.S. will leave the Paris agreement. The decision is likely to have a big impact on both the climate and environmental policy around the world.

President Trump is expected to make a decision regarding whether or not the U.S. will pull out of the Paris climate accord. NPR takes a look at the potential political and environmental impacts of leaving the agreement.

Today President Trump is at the G7 summit and high on the agenda is climate change. Many world leaders are imploring Trump stay in the global climate agreement, but emissions are going down already.

The Sea Grant program, which funds research on coastal environments, is slated by White House for elimination in 2018. If it goes, a project that finds leaking septic tanks goes down the drain, too.

A new survey shows that the sound of cars and planes and other forms of noise pollution are rampant across the American wilderness. In many cases, man-made noise is drowning out the background sounds.

The industry has been in decline for years, partly because burning coal creates CO2 and warms the atmosphere. But there's a way to capture it — which has drawn praise from traditional enemies.

Until now, the earliest signs of humans in the Americas dated back about 15,000 years. But new research puts people in California 130,000 years ago. Experts are wondering whether to believe it.

Native cutthroat trout, an iconic part of the mountain West, thrive in cold streams. But warmer weather has allowed invaders to move in — and it's killing off the cutthroats.

The idea behind "clean coal" is technology that would capture for reuse most of the carbon dioxide emitted by coal-burning power plants. Entrepreneurs aim to use similar tech to clean natural gas.

Scientists eavesdropping in trees have decoded a high stakes game of hide and seek. Katydids rely on ultrasound to find mates and listen for bats, which use ultrasound to find the bugs, and eat them.

This week's executive order to roll back climate regulations may sit well with the fossil fuel industry, but most of corporate America is unimpressed. Many large companies are sticking to their plans to tackle climate change by investing in renewable energy and green practices.

President Trump is expected to ditch the Clean Power Plan this week. The CPP regulations would reduce emissions of greenhouse gases that warm the planet. Without it, the U.S. won't live up to its pledge, made in Paris in 2015, to make deep cuts in emissions. That could jeopardize the Paris deal, in which nearly 200 nations made similar pledges.
