Science: 890 Million-Year-Old Sponge, Caffeinated Bees, Greenland Glaciers

Researchers debate whether an ancient fossil is the oldest animal yet discovered, and a new way to eavesdrop on glaciers.

In this episode:

01:04 Early sponge

This week in Nature, a researcher claims to have found a fossil sponge from 890-million-years-ago. If confirmed, this would be more than 300-million-years older than the earliest uncontested animal fossils but not all palaeontologists are convinced.

12:34 Eavesdropping on a glacier’s base

We hear about one researcher’s unorthodox attempt to listen in to the seismic-whisper at the foot of a Greenland glacier – a method that might reveal more about conditions under these enormous blocks of ice.

Western Drought: Expect More Fires & Water Wars

As of mid-June, nearly three-quarters of the US’s West has been experiencing “severe,” “extreme,” or “exceptional” drought conditions. In addition to the states above, it also includes northern states like North Dakota and Montana.

Overall, climate change is playing a role. But there are smaller factors at play that are tied to climate change as well. Including…

  • Not enough rain. The National Oceanic and Atmospheric Association (NOAA) said the Southwest’s 2020 monsoon season (read: ‘nonsoon’) was “the hottest and driest summer/monsoon season on record.” And the decrease in rainfall is having an impact on today’s drought (think: not enough water for crops, lakes, or reservoirs). And for the little rain that has fallen, it could dry up faster because of…
  • Warmer temps. The NOAA dubbed 2020 the second-hottest year on record. And in late June, a record-breaking heat wave hit the Pacific Northwest, with the temperature reaching up to 112 degrees Fahrenheit in places like Portland, OR. (Psst…if you’re dealing with hot weather, here are some tips to stay safe.) Hotter, drier weather creates a thirsty environment, which speeds up evaporation. Rising temps are also causing snowpacks to melt faster, and they’re reportedly producing less runoff – a vital water resource. All of which means there’s less water available for communities and ecosystems.

Experts are also worried that the current dry and hot conditions will have a ripple effect, which brings us to wildfires. Last year’s West Coast wildfire season was the worst ever. Fires in California killed 31 people, burned more than 4 million acres, and destroyed thousands of buildings and structures. And this year, states like Arizona have seen an early start to their wildfire season. But the effects of the drought stretch even further.

Zoology: The Evolution Of Seahorses (Video)

Sea horses are amazing animals because of many of their strange features like male pregnancy but also due to their beautifully unique body shape. However, this may be the reason why seahorses are famous but it actually makes them very bad swimmers so why did they evolve to have this unique body shape?

A seahorse is any of 46 species of small marine fish in the genus Hippocampus. “Hippocampus” comes from the Ancient Greek hippókampos, itself from híppos meaning “horse” and kámpos meaning “sea monster”.

Ocean Science: Can Kelp Forests Survive Climate Change, Trawler Fishing

Kelp locks up millions of tonnes of carbon globally, provides a nursery for fish and is a buffer against coastal flooding. But climate change, weather and fishing are taking their toll. Now, Mika Peck and his team at the University of Sussex are monitoring kelp off the south coast of the UK, to see if it can recover from the damage done to it by trawling and help improve biodiversity in the area.
