Fertilizer sourced from sewage sludge

Germany's new Waste and Sewage Sludge Ordinance requires large sewage treatment plants to recover phosphates from sewage sludge or ashes as of 2032. Conventional recovery technologies are costly and chemical-laden. A new ...

Acidified oceans may corrode shark scales

Prolonged exposure to high carbon dioxide (acidified) seawater may corrode tooth-like scales (denticles) covering the skin of puffadder shysharks, a study in Scientific Reports suggests. As ocean CO2 concentrations increase ...

New function for plant enzyme could lead to green chemistry

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered a new function in a plant enzyme that could have implications for the design of new chemical catalysts. The enzyme catalyzes, or ...

Methane-producing microorganism makes a meal of iron

A new understanding of how an important methane-producing microorganism creates methane and carbon dioxide could eventually allow researchers to manipulate how much of these important greenhouse gases escape into the atmosphere. ...

Early life on Earth limited by enzyme

The enzyme-nitrogenase-can be traced back to the universal common ancestor of all cells more than four billion years ago.

Researchers tune nanowire properties with peptide 'decorations'

In the latest paper from the Geobacter Lab led by microbiologist Derek Lovley at the University of Massachusetts Amherst, he and colleagues report "a major advance" in the quest to develop electrically conductive protein ...
