  • Aha! The Power Of A Short Rest

    Aha! The Power Of A Short Rest
    Jun 27 2025
    Since 2004, scientific research has shown that a full night of sleep may lend itself to a burst of insight in the morning. But what about the earlier stages of sleep? And what about just a nap? A research team based in Germany found that even a 20-minute nap could deliver a "eureka" moment, and published their findings in the journal PLOS Biology this week.

  • When Eavesdropping Pays Off

    When Eavesdropping Pays Off
    Jun 25 2025
    Why did the ornithologist strap a taxidermy badger to a remote controlled car and drive it around the prairie? To interrogate the secret world of animal eavesdropping in the grasslands, of course! Today on the show, we travel to the most imperiled ecosystem on the planet to unravel a prairie mystery and find out why prairie dogs are grassland engineers worth keeping tabs on.

  • Does It Feel Like Mosquitoes Are Getting Worse?

    Does It Feel Like Mosquitoes Are Getting Worse?
    Jun 24 2025
    Mosquitoes are the deadliest animal on the planet, and some of them may be on the rise. At least in listener Abigail Krich-Starr's area, that's due to warmer, wetter weather — which, yes, is linked to climate change. But it doesn't stop there: Ecologists and entomologists say increased heat could also alter mosquito behavior, shift their natural habitat, and even change how pathogens incubate and spread inside their bodies.

    So how do you protect yourself against the (mosquito) masses? Our experts suggested several things:
    - Assess your risk by checking local mosquito surveillance efforts, like this one for the state of Massachusetts
    - Consider rescheduling outdoor events happening between dusk and dawn, which is peak biting time for multiple mosquito species
    - Wear long-sleeved shirts and pants, weather-permitting, to limit exposed skin
    - Use an EPA-approved DEET repellent, and/or a permethrin spray for clothing and outdoor gear

    This episode is part of Nature Quest, a monthly Short Wave segment that answers listener questions about the local environment.
