Recreating ancient minerals

When it comes to making a lasting impression in geological history, the medium makes all the difference, especially in the Earth's paleo-oceans. Here, during the Archean Eon (4,000-2,500 million years ago) and at times during ...

Biodegradable plastic blends offer new options for disposal

Imagine throwing your empty plastic water bottle into a household composting bin that breaks down the plastic and produces biogas to help power your home. Now, researchers have taken an early step toward this futuristic scenario ...

Microbes corrode steel in ships, marine infrastructure

Rust is the bane of steel, whether on cars, on ships and boats, or as part of marine infrastructure. Now, contrary to previous thinking, it turns out that the ocean-dwelling, steel-corroding species, Mariprofundus sp. DIS-1, ...

C. difficile needs iron, but too much is hazardous

Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron ...

Starved-out bacteria aid in wastewater treatment

Scientists have adapted a process normally used to make bioplastic, to remove carbon from wastewater, slashing the amount of energy needed for the treatment process.

Beetles modify emissions of greenhouse gases from cow pats

Cattle contribute to global warming by burping and farting large amounts of greenhouse gases. Some of the same gases are also emitted from cow pats on pastures. But now researchers from the University of Helsinki have found ...

Antibiotics are unique assassins

In recent years, a body of publications in the microbiology field has challenged all previous knowledge of how antibiotics kill bacteria. "A slew of papers came out studying this phenomenon, suggesting that there is a general ...
