In the 1960s, the Bureau of Reclamation built a dam that flooded a celebrated canyon on the Utah-Arizona border. Today, it's known as Lake Powell — the second-largest reservoir in the U.S.
A half billion dollar tourism industry has grown in the desert around the reservoir but a decades-long megadrought is putting its future in question.
With what some call America's 'lost national park' reemerging, an old debate is also resurfacing: should we restore a beloved canyon or refill a popular and critical reservoir? Environmental and American West correspondent Nathan Rott brings this story to guest host Dan Charles. Read Nate's full story and see pictures by photojournalist Claire Harbage of their recent trip to Lake Powell here.

Many experts warn there will be more infections on the downslope of the omicron surge, but the U.S. is on the path to the virus becoming endemic — and that should mean fewer interruptions to daily life. Take a listen to Rachel Martin chat with health correspondent Allison Aubrey about what's next in the pandemic on Morning Edition.

Parkinson's disease is a brain disorder that leads to difficulty with walking, balance and coordination. There is currently no cure, but scientists in Pittsburgh, PA have an ambitious plan to develop a treatment based on the placebo effect. NPR science correspondent, Jon Hamilton, tells the story of how this plan came to be. It involves a batch of illegal drugs, the rabies virus, and figuring out what makes a monkey really happy.
The effects of the Tonga eruption could be felt around the world, many heard the boom of a sonic shock, and tsunami waves travelled far and wide. Volcanologist Shane Cronin from the University of Auckland in New Zealand is one of only a handful of people to have landed on the tiny islands above the volcano where the eruption took place. Those islands have now sunk beneath the waves but Shane tells us what he found when he went there and how his findings could inform what happens next.
Stephan Grilli from the School of Ocean Engineering at the University of Rhode Island joins us from Toulon in France where he felt the effects of the shockwave and Tsunami. He says the force of the shockwave drove those waves worldwide.
The oceans have continued to warm, producing continuous record temperature rises for several years now. That’s the finding of Michael Mann of the University of Pennsylvania and author of The New Climate Wars. He says warming occurred last year despite the presence of global weather patterns which would usually have a cooling effect.
The long-term effects of covid-19 on health are a cause of growing concern even though in many places the virus itself now appears to be taking on a milder form. Yale University neuroscientist Serena Spudich is particularly concerned with covid’s impact on the brain. She says while the SARS- CoV-2 virus might not be found in brain cells themselves there are neurological impacts.
Scientists have been searching for dark matter for decades, and think there’s six times more of it in the universe than the stuff we can actually see, like stars and planets. But they still don’t know what it is. So how can we be sure dark matter really exists? And why does it matter, anyway?
Back in 2018, armed with a boiler suit, hard hat and ear defenders, Marnie Chesterton travelled over a kilometre underground into a hot and sweaty mine to see how scientists are valiantly trying to catch some elusive particles – in the hope of settling things once and for all.
Several years on we return to the problem, tackling a few more CrowdScience listeners’ questions about dark matter, and hearing whether we’re any closer to uncovering its mysteries. We’re joined in our quest by Dr Chanda Prescod-Weinstein, physicist and author of The Disordered Cosmos: A Journey into Dark Matter, Spacetime, and Dreams Deferred.
With Professor Malcolm Fairbairn, Dr Chanda Prescod-Weinstein, Dr Chamkaur Ghag and Professor Katherine Freese.

The James Webb Space Telescope's mirrors are almost in place and soon it'll be a million miles away from Earth, ready to provide clues to the history of the universe. Naturally, many scientists have research they'd like to do that involve the telescope. Today on the show, Emily talks with correspondent Nell Greenfieldboyce about who gets time on it, and how decision-makers are working to stay focused on the proposed science instead of who will be doing it, in the hopes of making the process fair for all proposals.

The U.S. government has launched a website where people can request up to four free coronavirus tests per household--shipping is scheduled to begin in late January. They're responding to the fact that many Americans are really struggling to find tests as omicron surges across the country. (https://special.usps.com/testkits) Today on the show, our colleagues at Planet Money try to get tested — and they run into problems. From scammy testing sites to no tests at all, they explain what's behind the nation's COVID testing mess.
Sixty percent of electricity in the U.S. comes from fossil fuels, like natural gas and coal. Today on the show, guest host Dan Charles talks with reporter Julia Simon about how Hawaii is fighting climate change by throwing out what's been standard for many decades and encouraging the state's power company to make clean electricity.
