• Sip or Skip? The Truth About Electrolytes

  U.S. consumers spend more than $10 billion a year on sports drinks, according to Beverage Industry, a trade publication. And we can’t lie that sometimes a Gatorade or electrolyte tablet sounds really appealing in the quest to hydrate daily – especially since it’s been a very hot, long summer. But the question is: Are we even sweating enough to warrant all these sugary electrolyte-filled drinks? NPR health correspondent Pien Huang has been on the case, and she brings us answers she’s racked up in her reporting today.Read more of Pien’s reporting on electrolytes and hydration.Interested in more consumer health or human biology stories?

• What Marsquakes Reveal About The Planet's Habitability

  Mars is known for its barren desert landscape and dry climate. But two recent studies in the journals Nature and Science go beneath the surface, exploring the interior of the red planet using seismic data from NASA’s InSight mission. And now, this data is also giving scientists a glimpse into the planet’s history – to see how Mars evolved over billions of years and how its inner structure compares to that of Earth. Interested in more science news?

• Have a Stutter? It Could Be Inherited

  For a long time, scientists have suspected that stuttering — a common speech condition that affects an estimated 1 in every 100 people — could be heritable. Despite how common it is, it's still a remarkably understudied condition. Geneticists Piper Below and Dillon Pruett were determined to fix that. With the help of 23andMe data, they recently identified 57 genetic regions linked to stuttering in the human genome. Their findings represent a new breakthrough in how researchers think about speech conditions, genetics and the conditions that are linked to them. They're what some are calling a "quantum leap" in the field.Interested in more human biology and genetics episodes?

• Stopping SSRIs Can Be Hard. Researchers Are Unsure Why

  More than 1 in 10 people in the United States take an antidepressant. And the most commonly prescribed type of antidepressant are SSRIs — or selective serotonin reuptake inhibitors. That includes drugs like Zoloft, Prozac and Lexapro. But what happens when some patients decide they want to stop taking their SSRIs? While doctors know stopping SSRIs can sometimes cause unpleasant short-term side effects – like dizziness, anxiety, insomnia and nausea – some people report symptoms that last months, even years. So, with investigative reporter Emily Corwin and professor of clinical psychology Michael Hengartner, we’re diving into the research around the long-term effects of going off your antidepressants – what it shows and its limits. Read more of Emily Corwin’s reporting on the topic here. Want more stories on mental health?

• A (Monday Night) Football Mystery

  Monday night football is back! What better way to celebrate than a close look at some of the physics powering the sport? Specifically, the spiral pass. If you've ever watched part of a professional football game, you've probably seen a tight spiral pass. They're those perfect throws where the football leaves the player's hand and neatly spins as it arcs through the air. Those passes can seem to defy fundamental physics — and for a long time, scientists couldn't figure out exactly why. That is, until experimental atomic physicist Tim Gay cracked the case within the last few years. His answer comes after two decades of hobby research and more than a couple late night shouting matches with two other physicists over Zoom. (encore)Want more stories on sports science?
