In 1952, polio was everywhere: killing or paralyzing roughly half a million people annually. Yet just 10 years later, paralytic polio cases in the US dropped by 96% and we were on track to get rid of polio for good. But in recent years,...

Our DNA holds evidence of a huge, ancient pandemic, one that touched many different species, spanned the globe, and lasted for more than 15 million years.

We've been spending a lot fo time thinking about one vaccine: the COVID vaccine. But vaccines have been around since long before SARS-CoV-2 showed up, so let's learn about some of those other vaccines.

Having bacteria in your food doesn't really sound great, but you couldn't have yogurt without it! Learn why in this week's QQ!

Scientists are closely watching SARS-CoV-2 to track mutations and see if it's developed into different strains. So, has it?

If we’ve had vaccines for the polio virus for almost 70 years, why haven’t we been able to fully eradicate it from the globe? Hosted by: Hank Green (he/him)

Some of humanity’s favorite antibiotics are starting to lose their mojo, in the face of smart, sneaky, and rapidly-evolving bacteria. To find new drugs to combat these superbugs, scientists are looking in some weird new places, like...

Scientists are turning to unusual places to find new compounds to fight off drug-resistant “superbugs.” The discovery came from milking ferocious mammals!

By studying population-level epidemiological trends, researchers have noticed that an old vaccine for tuberculosis may provide some protection against COVID-19.

A new strain of the E. coli bacteria seems to have become resistant to most antibiotics. Let’s talk about how this possibly happened.

In the fight against antibiotic-resistant bacteria, we might be able to find new treatments by looking at some of the world’s most venomous snakes.

Evolutionary biologist Paul Ewald drags us into the sewer to discuss germs. Why are some more harmful than others? How could we make the harmful ones benign? Searching for answers, he examines a disgusting, fascinating case: diarrhea.

For almost a decade, scientists chased the source of a deadly new virus through China’s tallest mountains and most isolated caverns. They finally found it in the bats of Shitou Cave. The virus in question was a coronavirus that caused an...

Unlike measles, Influenza requires a fresh shot of vaccines every year. But why?

We might order fish raw, but why don't we ever order chicken that way?

Two separate groups of biologists reported fusing entire sets of Saccharomyces cerevisiae chromosomes together, and surprisingly, the actual number of chromosomes might not be as important as we thought.

Some experts feared we were in for a "twindemic" during the 2020-2021 flu season. That didn't happen, which might mean that there will be more people susceptible to getting sick this year.

All year long, researchers at hospitals around the world collect samples from flu patients and send them to top virology experts with one goal: to design the vaccine for the next flu season. But why do we need a new one every year?...

Each year, we try to fight flu season with the influenza vaccine and this year is no different. But why is there a flu season at all and how do we fight it?
