Like many states in the Midwest, Nebraska was somewhat spared during the early days of the pandemic. But now, the state has more cases per capita than any other in the country. We talk with two Omaha doctors who say this latest surge is exhausting health care workers, and one explains why she's tired of people calling health care workers heroes. Are you a health care worker who would like to share...

Some of the most popular agricultural biotech products are running into problems.

The safest way to have Thanksgiving this year is to stay at home. But realistically, we know many people will still be traveling to gather with loved ones. So in this episode, Emily and Maddie outline ways to gather as safely as possible. We'll cover best practices for quarantining before the trip, testing, ventilation and food preparation. That way, this Thanksgiving you can pass the turkey, hold...

The Trump administration has officially eliminated federal protections for Alaska's Tongass National Forest, the largest intact temperate rainforest in the world. With the rollback of the Roadless Rule, nine million previously-protected acres are now open further to potential development. What does that mean for trees that have been storing carbon for centuries? For more on this story, check out t...

Developing a safe and effective coronavirus vaccine will be crucial to getting the pandemic under control. Also important, distributing it throughout the country once it's been approved. NPR science reporter Pien Huang tells us which high risk groups will get it first, how the vaccine will be distributed (including some challenges), and who's footing the bill for all of this. Email the show at sho...

Interim results are in from a large trial of an experimental COVID-19 vaccine.

Today on Short Wave, host Maddie Sofia talks to NPR science correspondent Joe Palca about what that efficacy number means, details of the study and what more in...

In the future, genomic research could lead to new treatments for human disease. It turns the data in our DNA into a global commodity. But historically, minoritized communities have been left out of this research. Keolu Fox is a genome scientist trying to change that and advocate for a more equitable approach when Indigenous and other underrepresented communities do participate. Read Keolu's paper,...

There have been many climate-related disasters this year, and along with those events come a heavy emotional and financial toll for residents.

That's what they call themselves: long-haulers. They've been sick for months. Many have never had a positive test. Doctors cannot explain their illness any other way, and can only guess at why the virus appears to be with them for so long. Ed Yong of The Atlantic explains what might be going on, and why their experience mirrors that of other sufferers with chronic illnesses who battle to be believ...

President Trump announced his intention to withdraw from the landmark Paris climate agreement in 2017 and formally notified the United Nations last year.
