Selected Podcasts

What’s all the talk about mute swans?

Podcast

In the late 1800s, mute swans were brought from Europe to the eastern U.S. to enhance the beauty of ponds on private estates. Unlike the dark-billed native swans that migrate through our region in the spring and fall, mute swans are easily distinguished by their pinkish-orange bills. They also spend the entire year here.

Dirty drinking water

Podcast

A new government study is raising red flags about the safety of our drinking water. EPA and U.S. Geological Survey scientists analyzed treated water samples from 25 U.S. utilities. They found that more than 1/3 contained chemicals not regulated by the federal Safe Drinking Water Act.

Let’s quit carping about it

Podcast

In the 1960s, grass carp were brought to the U.S. from Asia to control weeds in southern fish-farming operations. Unfortunately, like so many other exotics, these fish escaped into the wild, and have been moving northward. As of last month, they were found to be reproducing in Lake Erie.

A mosquito fever expands its range

Podcast

A mosquito-borne virus that causes fever, headaches, and severe joint pain has spread to the Caribbean. Experts fear it's only a matter of time before it makes its way to the U.S. Chikungunya gets its name from an East African word meaning 'that which bends,' due to the posture of its sufferers.

Salty streams and rivers

Podcast

By the looks of it, we're in for quite a winter this year. Here in the Northeast, we've seen several heavy snowfalls, freezing temperatures, and icy roads.

Invaders underfoot in our forests

Podcast

Despite their familiarity, earthworms are an invasive species in America's northern temperate forests. They arrived in the mid-1800s, with the arrival of European settlers.

Let’s talk about ammonia

Podcast

Most of us are familiar with ammonia as an irritating gas that is emitted from window-cleaning fluids. It is a great way to cut through grease that has condensed on glass.

Tracking disease in a warming world

Podcast

Understanding how infectious diseases respond to climate change would help public health officials and environmental managers predict and mitigate disease impacts.

The hidden cost of antibacterial products

Podcast

Triclosan, a synthetic antibacterial used in personal care products, is fueling the growth of resistant bacteria in streams and rivers.

Dams complicate river management

Podcast

Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbances.

Warming the tundra

Podcast

A lot of dead plant material is stored in the tundra soils of the far north. Most of it is frozen in permafrost, and inaccessible to the microbes that normally decompose organic matter in soils.

Powassan encephalitis

Podcast

The number of tick-borne illnesses reported to the U.S. Centers for Disease Control and Prevention is on the rise. Lyme disease leads the pack, with some 35,000 cases reported annually. 

The signal before the collapse

Podcast

What do earthquakes, heart attacks, seizures, and the collapse of stock markets and fisheries have in common? They're all examples of what scientists call "tipping points" or "regime shifts."

How green is your grass?

Podcast

Most of us are familiar with the stereotype of the peace-loving, tree-hugging hippy with a penchant for marijuana. So just how green is grass grown in sunny California? The answer might surprise you.

When antibacterials go down the drain

Podcast

Around half of liquid soaps now contain the chemical triclosan, as do toothpastes, deodorants, cosmetics, and other personal care products.
