Researchers say the concept of achieving herd immunity threshold isn't the right finish line to end the pandemic. It's an elusive number to define in the first place, and it changes under various circumstances. Science correspondent Geoff Brumfiel talks with Maddie about the complexities in even defining the number and what the public should focus on instead.

Happy Pride, Short Wave Listeners! Here's a fun episode from our archives to celebrate the month!

It's another "Back To School" episode where we take a concept you were maybe taught in school as a kid, but didn't really learn or just forgot. Short Wave producer Thomas Lu and host Maddie Sofia go on a journey to explore what a rainbow exactly is and how we see them! We all remember ROY G BIV, right?

The latest Nyiragongo eruption was not entirely unexpected, the volcano’s lava lake inside the crater had been building up for years. Local volcanologists say it was only a matter of time before an eruption occurred. The big concern was where the flank of the volcano would be breached as the city of Goma rests under the volcano and there are potential fissures even within the town. However there are still questions over the effectiveness of seismic monitoring in the area, North Kivu. The Goma observatory has been unable to carry out this work due to a lack of funding. And monitoring is further complicated by the region’s long running civil war, with rebel groups often camped around the volcano. We hear from Dario Tadesco and Cindy Ebinger. Who have both been monitoring developments.

Cyclone Yass was the second Cyclone to hit India within a week. Are these events becoming more common and are they related to rises in global temperatures? Climatologist Roxy Koll has been monitoring the situation.

Greenland’s pristine glaciers might not be so pristine. Jemma Wadham from Bristol university and her team have found unexpectedly high levels of Mercury in meltwaters - similar to those from industrial pollution. They say research now needs to focus on the impact for wildlife and people in the Arctic region.

And the elusive Sowerby’s beaked Whale doesn’t travel very much despite pockets of the species being found across the Atlantic. Kerri Smith has been researching this species, which is rarely seen alive. Using samples from whales beached or caught accidentally she was able to build up a picture of their distribution.

As millions more of us move to live in densely populated cities, we almost inevitably face living in closer proximity to our neighbours. Neighbour noise can certainly be a source of annoyance – but could it even be damaging to our health?

Increasing evidence suggests that unwanted noise can cause sleep deprivation, distraction and annoyance, as presenter Anand Jagatia finds out. He discovers that noise annoyance has a small but significant impact on our wider health – including our cardiovascular system – but that annoyance is not necessarily down to sound alone. Factors such as perception of the neighbourhood and relationships with our neighbours also play a part.

CrowdScience has examined living with unwanted noises before, and we revisit our trip to the acoustics lab at the University of Salford in Manchester, UK. Here, we meet the researchers and engineers investigating the best ways to make our homes more pleasant for our ears whilst still maintaining the ‘buzz’ of city life.

Scientists and students with disabilities are often excluded from laboratories — in part because of how they're designed. Emily Kwong speaks to disabled scientist Krystal Vasquez on how her disability changed her relationship to science, how scientific research can become more accessible, and how STEMM fields need to change to be more welcoming to disabled scientists.

Juul Labs seemingly started out with the aim to reduce smoking, but the company's e-cigarettes came to symbolize something very different: a teen vaping epidemic.

Host Maddie Sofia talks with Time health writer Jamie Ducharme about the science and marketing behind the rise and subsequent controversy surrounding Juul Labs. Plus, a look at what might be next in the future of e-cigarettes.

Researchers report in the journal Science that they appear to have some clues about the origin of Earth's plutonium - which has been long debated. Correspondent Nell Greenfieldboyce explains that traces of rare forms of iron and plutonium have been found in extraterrestrial debris that had sunk to the bottom of the Pacific Ocean, hauled up by an oil company, then donated for research. By comparing the iron and the plutonium, scientists found the plutonium was likely forged in a cosmic cataclysm, perhaps a rare kind of supernova, and then rained down on Earth.

Eight states have passed an important milestone: getting 70% of all adults vaccinated with at least one shot. That's a number President Biden wants the country to reach by July Fourth. As cases of COVID-19 in the U.S. continue to come down, host Maddie Sofia talks with NPR health correspondent Allison Aubrey about vaccination progress around the country.

**Heads up. This episode discusses addiction and alcoholism.**

Some doctors are seeing a disturbing spike in lethal alcoholic liver disease, especially among young women. The recent trend has been supercharged, they say, in the pandemic. Emily Kwong speaks to NPR science correspondent Yuki Noguchi about this and some of the challenges to getting proper treatment.
