29-Fire: Lighting the skies with fireflies
Did you ever wonder how random flashes of fireflies gradually acquire synchrony? Studies have shown that this surreal coordination of twinkling occurs through a natural cadence among certain species of fireflies during the mating season.

We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must…

We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must be a reason why such legends were created in the first place. In most cases, the legend in grounded in fact.

This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

To the untrained eye, Arctic ice appears unchanging, but conditions can shift quickly, and often reveal life-threatening hazards when they do. It is an unforgiving environment, but the Inuit know how to navigate it. That knowledge has been passed down through generations, and a new app is giving centuries-old Inuit knowledge a very modern form.

Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.

Anant Pande is an Indian polar researcher who studies snow petrels – shy pelagic (sea-faring) birds who nest on rock crevices in Antarctica. These endemic birds prefer to nest near less icy waters. Climate change has melted polar oceans and perhaps made it less energy intensive — as they have to fly shorter distances to find non-frozen oceans.

Cool off from the summer heat with our next six-part miniseries all about ice – from those who call it home to its use as a tool in science.

The Cambrian explosion is commonly labelled as the time in Earth’s history when animals suddenly appear. But research from geoscientist Rachel Wood and her team turns this explanation on its head.

When you hear the word “extinction,” chances are you probably think of the extinction of the dinosaurs and a big rock. But did you know that there were other factors at play that lead to that extinction including volcanos and sea-level rise?
