## Microalgae vs. mercury

August 8, 2023

In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

## Jerry Parks: Solving protein puzzles for better environmental, human health

May 30, 2023

When reading the novel *Jurassic Park* as a teenager, Jerry Parks found the passages about gene sequencing and supercomputers fascinating, but never imagined he might someday pursue such futuristic-sounding science. 

## Marie Kurz: Helping science on watersheds flow across disciplines

February 4, 2022

Spanning no less than three disciplines, Marie Kurz’s title — hydrogeochemist — already gives you a sense of the collaborative, interdisciplinary nature of her research at ORNL.

## Microbial “theft” enables breakdown of methane, toxic methylmercury

September 27, 2021

A team led by ORNL and the University of Michigan have discovered that certain bacteria can steal an essential compound from other microbes to break down methane and toxic methylmercury in the environment. 

## Living laboratory, biodiversity hub: The Oak Ridge National Environmental Research Park

September 15, 2021

Anyone familiar with ORNL knows it’s a hub for world-class science. The nearly 33,000-acre space surrounding the lab is less known, but also unique. 

## Teresa Mathews: Tackling mercury pollution for healthier aquatic ecosystems 

August 26, 2021

Moving to landlocked Tennessee isn’t an obvious choice for most scientists with new doctorate degrees in coastal oceanography. 

## A river runs through it: Upgrades to Aquatic Ecology Laboratory facilitate mercury research

October 22, 2020

New capabilities and equipment recently installed at the Department of Energy’s Oak Ridge National Laboratory are bringing a creek right into the lab to advance understanding of mercury pollution and accelerate solutions.

## Alex Johs: Using neutrons for biological and environmental science

July 1, 2019

Sometimes solutions to the biggest problems can be found in the smallest details. The work of biochemist Alex Johs at Oak Ridge National Laboratory bears this out, as he focuses on understanding protein structures and molecular interactions to resolve complex global problems like the spread of mercury pollution in waterways and the food supply.

## Ecology—Unmasking mercury

September 4, 2018

Biologists from Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have confirmed that microorganisms called methanogens can transform mercury into the neurotoxin methylmercury with varying efficiency across species.

## Newly identified microbial process could reduce toxic methylmercury levels

May 31, 2017

A team led by the Department of Energy’s Oak Ridge National Laboratory has identified a novel microbial process that can break down toxic methylmercury in the environment, a fundamental scientific discovery that could potentially reduce mercury toxicity levels and sup...
