As we hear pressures to roll back some of the provisions that ensure clean air, largely in pursuit of unfettered economic activity, it is worth spending a little time reflecting on the benefits of clean air to human health.

Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies.

In urban streams, persistent pharmaceutical pollution can cause aquatic microbial communities to become resistant to drugs.

More than 240 scientists and researchers from around the world recently descended on the Hudson Valley to strengthen an international partnership aimed at studying and understanding the world’s lakes.

Effective conservation begins with a keen understanding of where species live and what environmental conditions they need to survive. Using new modeling techniques fueled by citizen science, Vijay Ramesh and colleagues have developed a data-driven method to accurately map where species live so that these areas, and the species within them, can be protected. 

Charles Canham studies the dynamics of forest ecosystems and how they respond to a wide range of human impacts. Using field research, novel statistical methods, and computer models, Canham predicts forest response to factors including climate change, introduced pests and pathogens, logging regimes, and air pollution. He is the author of Forests Adrift: Currents Shaping the Future of Northeastern Trees.

North America’s freshwater lakes are getting saltier. The culprits: development and road salt. So reports an extensive study of 371 lakes conducted by a team of researchers in the Global Lake Ecological Observatory Network (GLEON) Graduate Student Fellowship Program, an initiative led by Cary Institute scientist Kathleen Weathers. 

Africa’s Serengeti-Mara ecosystem is home to one of the largest overland animal migrations in the world. Each year, more than a million wildebeest journey between Tanzania and Kenya in search of food and water.

Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems.

Through a $2 million National Science Foundation grant, scientists are harnessing the power of machine learning to forecast outbreaks of zoonotic disease.

Baltimore City faces a vexing, decades-old question: How do you transform 14,000 vacant lots and properties into healthy neighborhoods? It may just start with a flower meadow.

Recent news of the discovery of the emerald ash borer in Franklin County and the hemlock woolly adelgid near Lake George crystallizes the threat that imported forest pests pose to the Adirondacks. The emerald ash borer, a small green beetle from Asia, is poised to wipe out all of the ash trees in the region — and potentially North America.

Even though the natural movements of CO2 are enormous, all indications are that the total inputs and outputs to the atmosphere were well-balanced before the Industrial Revolution, because the CO2 concentration was not changing very much.

With support from a $1.47 million grant from the National Aeronautics and Space Administration (NASA), an interdisciplinary team of researchers are developing high-tech tools to monitor cyanobacteria in lakes, predict impending blooms, and identify factors that are degrading water quality.  

Stuart Findlay has worked on the Hudson River for over 30 years. His research on sensitive wetlands, shoreline restoration, and environmental monitoring is helping to guide the river’s recovery.

Findlay is committed to carrying science from discovery to dissemination and is actively engaged with a wide array of management, outreach, and educational programs.

Hurricanes Harvey, Irma and Maria, which hit in August and September, are estimated to be the most costly ever to make landfall in the United States. The damage they caused calls for a major investment in infrastructure that is resilient to such extreme events.

The Urban Water Innovation Network (UWIN) links researchers across the United States who represent a range of academic disciplines and are intellectually connected by a common interest in solving urban water issues.

Through a $1.2 million grant from the National Science Foundation, the Baltimore Ecosystem Study (BES) is partnering with Baltimore City Public Schools to transform the way that chemistry is taught in the city’s high schools. The innovative approach draws on data gathered by BES to convey how chemistry shapes the local environment.

With support from a $1.5 million National Science Foundation grant, Christopher Solomon is co-leading a study assessing links among people, lakes, and fish in the Northern Highland Lake District in Wisconsin.

More than a million wildebeests migrate each year in East Africa, moving from Tanzania to Kenya and back again. These antelopes, also known as gnus (NEUZ), follow the rains and abundant grass that will later spring up.
