Mercury is not well detoxified by yelloweye rockfish, researchers find

It takes six months to get really good at accurately gauging the age of yelloweye rockfish. Because they can live for up to 120 years, this species is of particular interest to Benjamin Barst and scientists like him who study the effects of toxic chemicals on living organisms.

Human drugs alter cricket personality

Crickets that are exposed to human drugs that alter serotonin levels in the brain are less active and less aggressive than crickets that have had no drug exposure, according to a new study led by researchers from Linköping University. The findings have been published in Scientific Reports.

Cells retain memory of chemical signals to which they are exposed

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are cultivated over the course of development.

Study highlights global and local impacts of delayed mercury-controlling policies

Mercury is an incredibly stubborn toxin. Once it is emitted from the smokestacks of coal-fired power plants, among other sources, the gas can drift through the atmosphere for up to a year before settling into oceans and lakes.

Study outlines how gut bacteria may influence behavior, including movement

A new study puts a fresh spin on what it means to "go with your gut." The findings, published in Nature, suggest that gut bacteria may control movement in fruit flies and identify the neurons involved in this response.

Scientists find high levels of previously unsuspected pollutant in homes, environment

Scientists at Indiana University found high levels of a previously unsuspected pollutant in homes, in an electronic waste recycling facility and in the natural environment. People are likely to be exposed to this pollutant by breathing contaminated dust or through skin contact.
