In June 2020, Amazon, Microsoft and IBM announced that they were limiting some uses of their facial recognition technology. In this encore episode, Maddie and Emily talk to AI policy analyst Mutale Nkonde about algorithmic bias — how facial recognition software can discriminate and reflect the biases of society and the current debate about policing has brought up the issue about how law enforcemen...

Some of the most prestigious scientists in history advanced racist and eugenicist views, but that is rarely mentioned in textbooks.

Archival records may help researchers figure out how fast the sea level is rising in certain places. Millions of people in coastal cities are vulnerable to rising sea levels and knowing exactly how fast the water is rising is really important. But it's a tough scientific question. NPR climate correspondent Lauren Sommer explains how scientists are looking to historical records to help get at the a...

Global Witness documented that 212 environmental and land activists were murdered in 2019. Over half of those documented murders took place in Colombia and the Philippines, countries where intensive mining and agribusiness has transformed the environment. NPR Short Wave reporter Emily Kwong speaks with three activists about the intersection between natural resource extraction and violence, and wha...

Why is it so hard to feel the difference between 400,000 and 500,000 COVID-19 deaths—and how might that impact our decision making during the pandemic? Psychologist Paul Slovic explains the concept of psychic numbing and how humans can often use emotion, rather than statistics to make decisions about risk. Email the show at shortwave@npr.org .

We're going "Back To School" today, revisiting a classic at-home experiment that turns lemons into batteries — powerful enough to turn on a clock or a small lightbulb. But how does the science driving that process show up in household batteries we use daily? Emily Kwong and Maddie Sofia talk battery 101 with environmental engineer Jenelle Fortunato. See pcm.adswizz.com for information about our co...

People of color experience more air and water pollution than white people and suffer the health impacts. The federal government helped create the problem, and has largely failed to fix it. NPR climate reporter Rebecca Hersher talks about the history of environmental racism in the United States, and what Biden's administration can do to avoid the mistakes of the past.
