Turning mine waste into healthy soil

Tailings, the waste left after extracting precious and critical minerals, often contain harmful chemicals and heavy metals that can pollute soil, water, and even crops. There are over 1,800 tailings storage facilities around ...

Research reveals new challenges for mercury cleanup

More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience. The discovery provides scientists with another piece of the mercury puzzle, ...

Mammals shape their microbiome to prevent disease

Gut microbes are well known to contribute to health and disease, but what has been less clear is how the host controls gut microbes. A study published January 13 in Cell Host & Microbe now reveals that mice and humans produce ...

Moth gut bacterium defends its host by making antibiotic

Nearly half of all insects are herbivores, but their diets do not consist of only plant material. It is not uncommon for potentially harmful microorganisms to slip in during a feast. In a study published on January 19 in ...

Do microbes control the formation of giant copper deposits?

One of the major issues when studying ore deposits formed in surficial or near-surface environments is the relationship between ore-forming processes and bacteria. At a first glance, these environments appear to be a preferred ...

CRISPRing the microbiome is just around the corner

To date, CRISPR enzymes have been used to edit the genomes of one type of cell at a time: They cut, delete or add genes to a specific kind of cell within a tissue or organ, for example, or to one kind of microbe growing in ...

A microbe's membrane helps it survive extreme environments

Within harsh environments like hot springs, volcanic craters and deep-sea hydrothermal vents – uninhabitable by most life forms – microscopic organisms are thriving. How? It's all in how they wrap themselves.
