This July 4th, are you a thrill- or chill-seeker?

Independence Day is approaching! Imagine if someone has procured illegal fireworks from a couple of states over. Are you: 1. first in line to light them? 2. content to watch while others set them off? 3. going to find a fire extinguisher — just in case — while loudly condemning the activity? Ken Carter [https://www.drkencarter.com/], a psychologist at Oxford College of Emory University, says everyone has a different level of sensation-seeking. This episode, we get into the factors at play, like people's brain chemistry, when deciding whether or not to do an activity, like setting off fireworks. For low and average sensation-seekers, very thrilling activities like large, self-run fireworks displays can cause their bodies to produce a lot of cortisol, a stress hormone. On the other hand, high sensation-seekers, Carter says, "don't tend to produce that much cortisol when they're in those highly chaotic experiences. So when they're seeing those fireworks, they actually produce higher amounts of another chemical called dopamine, which is a neurotransmitter or a chemical messenger that's involved in pleasure." Carter has developed a 40-point self-assessment survey for people to figure out how much of a sensation-seeker they are. The survey can be found in his book, Buzz!

Is setting your trash on fire a good idea?

The U.S. generates 292 million tons [https://www.epa.gov/facts-and-figures-about-materials-waste-and-recycling/national-overview-facts-and-figures-materials] of trash each year – and that trash has to go somewhere.  Sometimes, that’s to an incinerator, where it’s burned and turned into electricity. Proponents of incineration applaud the ability to generate energy from waste and divert garbage from landfills. Opponents worry about the potential health risks, especially to minoritized communities. Today on the show, we explore the good and the bad of waste-to-energy facilities – and even get to see one up close. Interested in more deep dives into the often invisible science powering our lives?

Ticks are a growing problem, no matter where you live

In the grand scheme of things, Lyme disease is a fairly new scientific discovery. It was first traced back to ticks in the late 70s and early 80s. The tick-borne illness can cause a rash, fever, pain, neurological complications, and even facial paralysis. It’s spread by only two of the nearly 50 species of ticks [https://pubmed.ncbi.nlm.nih.gov/35973261/] in the United States. Historically, most Lyme cases [https://www.cdc.gov/lyme/data-research/facts-stats/lyme-disease-case-map.html] were limited to a small region, including the Great Lakes area and northeastern US. But thanks to changing temperatures, animal migration and shifts in land use, scientists say tick territory is expanding. So what does that mean for Lyme disease risk? And do you have to be worried about it in your own backyard? Interested in more episodes about pests and parasites? Email us your question at shortwave@npr.org [shortwave@npr.org].

Is working from home actually good for you?

For many, being able to work from home is a boon: saving time on your commute, working in your sweatpants, throwing in a load of laundry before a meeting. People say it makes them happier. But a new study suggests that, despite all the advantages, working from home isn’t creating a happier workforce. It’s making people more socially isolated. We get into all the details with NPR mental health correspondent Rhitu Chatterjee [https://www.npr.org/people/578890280/rhitu-chatterjee]. Interested in more everyday science?

Salty Clouds aren’t the only strange thing about this object in space

There’s an object in space 25 times the size of Jupiter that’s stumped scientists for years. They haven’t been able to figure out if it’s a planet or a failed star. But scientists are one step closer to an answer thanks to the powerful James Webb Space Telescope. After analyzing data collected by the telescope, astronomers have uncovered unexpected new clues floating light years away from us: Salty clouds sitting in space as hot as some home ovens. And if this mystery isn’t enough, we have more to look forward to in this episode, including insights into the evolution of laughter and the burials of ancient human relatives.  Interested in more science in the news?
