Marijuana is decriminalized or legal in some form in multiple states. But, because it’s illegal on the federal level, states have had to build their own regulatory infrastructure. Without a centralized body to guide them, regulations in one state can look vastly different from those in another. For more on the scope of the issue, Short Wave host Regina G. Barber talks to independent science journalist Teresa Carr and NPR pharmaceuticals correspondent Sydney Lupkin. Read more of Teresa’s reporting on state marijuana testing, and more of Sydney’s reporting on the ways California is trying to make weed safer.Interested in hearing more science behind consumer products?

There are more human cells in your body than there are stars in the Milky Way galaxy! Cells are the fundamental building blocks of life but that doesn’t mean they are simple – biology still doesn’t have a full picture of how exactly a living cell works. Host Regina G. Barber talks with bioengineers Kate Adamala and Drew Endy about why scientists are trying to build a cell from scratch, piece by piece. They dive into what it would look like to be inside of a cell, why scientists are bothering with making a cell from scratch and how engineers are leading the field.Want more bioengineering stories?

Weather in the tropics is decidedly different than it is in the middle latitudes. It turns out, so are the weather systems – the factors that create things like the daily temperature and humidity! Historically, most weather forecasting models have been based on data from high-income countries in the northern hemisphere. But different factors drive weather and climate near the equator – meaning that these weather forecast models are much less accurate at predicting weather in the tropics. This has implications for storm readiness, flooding preparedness and more. Atmospheric scientist Ángel F. Adames-Corraliza is aiming to change that. His research focuses on how water vapor – humidity – plays a key role in tropical weather systems. It’s earned him a spot as one of this year’s Macarthur Fellows. Interested in more science about how weather happens?
