Burnout has long been a problem among health care workers. The pandemic has only made it worse. Some were hopeful COVID vaccines would provide some relief, but that hasn't been the case. Now, health care workers are leaving the industry — and they're taking their expertise with them. Plenty of surveys say that burnout hurts patient care. NPR correspondent Yuki Noguchi spoke to medical workers who agree, the burnout they see on the job means that sometimes patients are not getting what they need.

Since their discovery in the 1970s, artemisinin-based drugs have become the mainstay of treatment for malaria caused by the Plasmodium falciparum parasite. Researchers have identified artemisinin-resistant malaria parasites in Southeast Asia since the early 2000s, but now, there is evidence of resistance in Rwanda and Uganda. Dr Betty Balikagala of Juntendo University tells us how this resistance developed and what it means for managing malaria in Africa, which carries the greatest burden of malaria cases and deaths worldwide.

We hear from some of the scientists from COVID Moonshot, a non-profit, open-science consortium which has just received key funding to develop affordable antivirals to stop SARS-CoV-2 in its tracks.

Also on the programme, Dr Rakesh Ghosh from the University of California, San Francisco tells us how air pollution is contributing to 6 million preterm births globally each year, and Dr Catherine Nakalembe of the University of Maryland and Africa Lead for NASA Harvest returns to the programme as NASA/USGS launches Landsat 9.

Also In the past 18 months we have heard lots about the human immune system, as we all learn about how our bodies fight off Covid-19 and how the vaccine helps protect us. But this got listener John, in Alberta, Canada, thinking about how trees and plants respond to diseases and threats. Do they have immune systems and if so, how do they work? Do they have memories that mean they can remember diseases or stressful events 5 months, or 5 years down the line, to be better prepared if they encounter the same threats again?

Presenter Marnie Chesterton sets out to investigate the inner workings of plants and trees, discovering that plants not only have a sophisticated immune system, but that they can use that immune system to warn their neighbours of an attack. Some researchers are also investigating how we can help plants, especially crops, have better immune systems – whether that’s by vaccination or by editing their genes to make their immune systems more efficient.

But some plants, like trees, live for a really long time. How long can they remember any attacks for? Can they pass any of those memories on to their offspring? Crowdscience visits one experimental forest where they are simulating the future CO2 levels of 2050 to understand how trees will react to climate change.

A paper published recently in the journal Science finds similarities between the babbling of human infants and the babbling of the greater sac-winged bat (Saccopteryx bilineata) — a small species of bat that lives in Central and South America. As science correspondent Geoff Brumfiel reports, the researchers believe both bats and humans evolved babbling as a precursor to more complex vocal behavior like singing, or, in the case of people, talking.

People are likely to be confused by common climate change terms like "mitigation" and "carbon neutral," according to a recent study. So how can everyone do a better job talking about climate change so that no one's left confused? NPR climate correspondent Rebecca Hersher tells us the key turns out to be pretty simple.

Suicide was the 11th leading cause of death in the U.S. in 2020, according to the most current data. But research shows that suicide is preventable. Host Emily Kwong talks with NPR health correspondent Rhitu Chatterjee about the signs that someone you know may be thinking about dying, the ways you can support them, and how to possibly prevent suicide. (Encore episode.)

Based on early estimates, as many as 10,600 large sequoias were killed in last year's Castle Fire — up to 14% of the entire population. The world's largest trees are one of the most fire-adapted to wildfires on the planet. But climate change is making these fires more extreme than sequoias can handle. It's also worsening drought that is killing other conifer trees that then become a tinder box surrounding the sequoias, reports climate correspondent Lauren Sommer. Scientists warn that giant sequoias are running out of time and they're racing to save them.

He's been reporting about the pandemic for a while now, so he knows the risks of a breakthrough infection, is vaccinated, and follows COVID guidelines as they change. Nonetheless, he got COVID - and today on the show, Will shares what he learned about his breakthrough infection, and what he wish he'd known before his "mild" case.

Researchers studying bats in Northern Laos have found evidence that brings us closer than ever to understanding the origin of Covid-19. Since the beginning of the coronavirus pandemic scientists have tried to pin-point the exact origin of SARS-CoV-2. But recent evidence from the Institut Pasteur has identified several novel coronaviruses with similarities to the current coronavirus in bats. Professor Marc Eliot spoke to Roland Pease about how this research could give us a better idea where Covid-19 came from.

Could an oral COVID treatment be available soon? Daria Hazuda, responsible for infectious disease and bacteria research at MSD tells us about their clinical trials for an oral antiviral drug that could combat Covid-19: Molnupiravir.

Early Diagnosis of Alzheimer's Roland Pease travels to Bath to meet scientists who may have developed a way to diagnose Alzheimer's in the earlier stages of the disease. Dr George Stothart, has led the team from Bath university in the development of this simple 2 minute test.

Inducing Earthquakes Scientists are experimenting with artificially managing earthquakes by injecting fluid into fault lines. Professor Derek Elsworth at Pennsylvania state university explains his research into how these induced earthquakes can be more tightly controlled.

This year has been a weird one for UK gardeners – unpredictable spring temperatures meant flowers failed to bloom and throughout the rainy summer, slugs have been savaging salad crops. But why and when plants blossom is about more than just early cold spells and wet weather, and a listener in California has asked Crowdscience to investigate.

Flowering is vital to both plants and us. Without it, they wouldn’t be able to evolve and survive (and we wouldn’t have anything to eat). Anand Jagatia hears that different species have developed different strategies for doing this based on all sorts of things, from where they’re located to how big they are to what kind of insects are around to pollinate them. The famously stinky Titan Arum, or corpse flower, for example, blooms for a single day once every decade or so before collapsing on itself and becoming dormant again.

This gives it the best chance of attracting carrion beetles in the steamy Sumatran jungle. But other plants open their petals much more regularly, which is a process regulated by a clever internal clock that can sense daylight and night. It’s even possible to trick some of them into producing flowers out of season. Cold is also a vital step for some brassicas and trees, and scientists are starting to understand the genes involved. But as climate change makes winters in parts of the world warmer and shorter, there are worrying knock on effects for our food supply.
