The Omicron surge may have peaked in the U.S., but parts of the world are seeing crippling levels of cases. Jason Beaubien, NPR global health and development correspondent, joins the show to talk about where the virus is spreading, different countries' strategies for controlling the pandemic and what vaccinations look like globally.

There are now a number of biological indicators for the potential development of long covid. Immunologist Onur Boyman of Zurich University Hospital and Claire Steves, Clinical Senior Lecturer at King’s College London strives to tell us how pinpointing these factors is now helping in the development of strategies to predict the syndrome and prepare treatment.

The James Webb telescope has reached its final orbit. The years of planning, preparation and rehearsal seem to have paid off. The telescope is now ready to begin its mission of looking back into the early universe. BBC Science correspondent Jonathan Amos has followed the mission.

The widely held view that human development was propelled by our ancestors developing a taste for meat is being questioned by a new analysis of the fossil record. Paleoanthropologist Andrew Barr of George Washington University suggests part of the reason for this assumption is the sampling method, actively looking for evidence to support the hypothesis.

And Michael Boudoin of Lille University has led a team of physicists who have produced the longest-lasting soap bubble ever – they managed to prevent the bubble from popping for well over a year.

A few years back, a radio telescope in Australia picked up a radio signal that seemed to be coming from a nearby star. One possibility? Aliens! NPR science correspondent, Geoff Brumfiel, joins the show to talk about the signal and how a hunt for extra-terrestrial life unfolded.

Check out the work from Sofia Sheikh and her team at the Berkeley SETI Research Institute about what they learned from the signal: https://bit.ly/3rM6hCo

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.

This episode was produced by Berly McCoy, edited by Stephanie O'Neill and fact checked by Katherine Sypher. The audio engineer for this episode was Josephine Nyounai.

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.

For more of Nell's reporting, check out, Who gets to use NASA's James Webb Space Telescope? Astronomers work to fight bias. (https://n.pr/3tH2vwJ)
