Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.

For the endangered Kemp’s ridley sea turtle, every individual matters. A team of veterinarians and biologists has formed a network along the Gulf Coast to save injured sea turtles and the species.
Shorebirds gather by the thousands at important feeding and resting areas, but how individual birds move among sites remains a mystery.
In northwest Mexico, biologists are building a network of radio towers to track how individual migratory birds move among important wetland areas.

Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?

Birds found along the Gulf Coast have evolved to ride out hurricanes and tropical storms. But with development degrading the marshes where they live, it’s getting harder for them to bounce back.
A sedated coyote about to be released with a tracking collar in greater Los Angeles.
Biologists capture and collar coyotes in urban Los Angeles in order to study the effectiveness of ‘hazing’ as a wildlife management tool.
Using new technology to answer questions about shark reproduction.
Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.

Scientists behind a major new study explain how they discovered these forests are becoming less able to sequester carbon.
One of two underwater gliders is deployed from a research ship into Antarctic waters.
Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn’t make radio contact when it’s supposed to.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical ‘cores’ of the sediment and rock that’s as much as two miles down at the ocean floor.

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
It takes a giant piece of equipment to look deep inside a tiny atom.

It turns out to be fairly complicated to figure out how electricity will flow through materials – a crucial question for designing new electronics and semiconductor materials.
Each wolf calls with its own ‘voice.’
Tracking wild animals can provide lots of valuable data. New research suggests audio recordings of wild wolves can replace the typical radio collars, which can be expensive and intrusive.
Author Tom Iliffe leads scientists on a cave dive.
Scientific fieldwork that happens underground and underwater in spectacular but dangerous caves opens a window on a largely unknown world.

Epidemiologists study disease outbreaks in populations to determine who gets sick and why. In the wake of this year’s hurricanes, they are assessing impacts from mold, toxic leaks and other threats.
Science is a human approach to understanding the world.
Science provides a useful way to explore and understand the natural world. But it also has a richness, diversity and creativity that is often overlooked.
Hiscox and students practice for the big day with a weather balloon.
Meteorology researchers across the country are prepping experiments for the mini-night the eclipse will bring on August 21 – two minutes and 36 seconds without the sun in the middle of the day.
Into the unknown.
In this episode of The Anthill podcast we are off exploring: land, sea and space.
