To explore deep space, scientists say we'll need better clocks. Here's why

1 week ago | wrvo.org | Emily Kwong |Regina Barber |Hannah Chinn |Rebecca Ramirez

Happy Memorial Day, Short Wavers! This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location, Internet timing, stock trading and even space navigation. In today's encore episode, hosts Emily Kwong and Regina G. Barber learn how to build a better clock. In order to do that, they ask: How do atomic clocks really work, anyway? What makes a clock precise?
Our medications are leaking into waterways - and may be changing fish behavior

1 month ago | wrvo.org | Jonathan Lambert |Emily Kwong |Hannah Chinn |Rebecca Ramirez

A fish walks into a pharmacy ... It's the start of a joke – with echoes in reality. Sort of. Fish aren't being prescribed anti-anxiety drugs. But they are experiencing the effects. That's because fish and other aquatic creatures are being affected by increasing levels of drug pollution – from human waste or pharmaceutical factory runoff – that then seep into our waterways. Researchers have found more than 900 different pharmaceutical ingredients in rivers and streams around the world.

Why it's hard to study the neuroscience of psychedelics

2 months ago | tpr.org | Rachel Carlson |Regina Barber |Hannah Chinn

Researchers are studying psychedelics as a possible treatment for conditions like depression, PTSD and substance use disorders. But they don't know exactly how these drugs work. Getting the answer to this question is especially difficult when people often take psychedelics like LSD and psilocybin for their trademark "trips."Some researchers think these psychoactive, spiritual effects are a big part of why patients could benefit from psychedelic drugs.

What the COVID-19 pandemic tells us about how viruses evolve

2 months ago | tpr.org | Hannah Chinn |Sarah Zhang

Early in the beginning of the COVID-19 pandemic, scientists predicted the coronavirus would mutate slowly. They were wrong. Hundreds of thousands of viral mutations and multiple seasonal waves later, researchers now know why. Turns out, SARS-CoV-2 — the virus that causes the disease COVID-19 — was making evolutionary leaps and bounds in one specific group of people.
The science behind the FDA ban on food dye Red No. 3 : Short Wave

Red No. 3 is banned by the FDA due to cancer link : Short Wave On Wednesday, the Food and Drug Administration announced it is banning the dye called Red No. 3, a food dye additive in many processed foods, like sodas, sweets and snacks. Recently, it and other dyes were linked to behavior issues in children. But high levels of Red No. 3 were linked to cancer in rats decades ago. So why is the ban happening now?
