Microorganisms protect iron sheet piling against degradation

A natural biofilm of oxygen-free microorganisms protects iron sheet piling against corrosion by depositing minerals on the wall. That is what researchers at the Radboud University, the Dutch Institute of Ecology (NIOO-KNAW) ...

Methane production reduced in ruminants

Researchers at the Spanish National Research Council (CSIC) have taken part in a study of the effect of one molecule, 3-nitrooxypropanol, in inhibiting methane production in ruminants. The work has been published in the Proceedings ...

Sewage lagoons remove most—but not all—pharmaceuticals

(Phys.org)—2012 marked the 40th anniversary of the Clean Water Act, which established regulations for the discharge of pollutants to waterways and supported the building of sewage treatment plants. Despite these advances, ...

Lack of energy an enemy to antibiotic-resistant microbes

(Phys.org)—Rice University researchers "cured" a strain of bacteria of its ability to resist an antibiotic in an experiment that has implications for a long-standing public health crisis.

Researchers unravel the mystery of marine methane oxidation

(Phys.org)—Microbiologists and geochemists from the Max Planck Institute for Marine Microbiology, along with their colleagues from Vienna and Mainz, show that marine methane oxidation coupled to sulfate respiration can ...

Oxygen 'sensor' may shut down DNA transcription

(Phys.org) -- A key component found in an ancient anaerobic microorganism may serve as a sensor to detect potentially fatal oxygen, a University of Arkansas researcher and his colleagues have found. This helps researchers ...

LANL develops first genetically engineered 'magnetic' algae

LANL scientists have genetically engineered "magnetic" algae to investigate alternative, more efficient harvesting and lipid extraction methods for biofuels. The researchers seek to reduce the cost of algae-based biofuel ...

Singapore honours Dutch scientist

Singapore said Monday it will award nearly 200,000 US dollars to a Dutch scientist who pioneered an environmentally friendly, low-cost way of treating waste water and refused to patent the process.
