Microbes Found to “Breathe” Iron, Combat Ocean Dead Zones

Researchers have identified a novel microbial metabolism where bacteria “breathe” iron minerals to eliminate toxic sulfide. This biological process, occurring in marine sediments and wetlands, may help prevent the expansion of oxygen-depleted dead zones in oceans and lakes while playing a significant role in global element cycles.

A New Player in Planetary Detoxification

Scientists have uncovered what appears to be a previously unknown form of microbial metabolism that could play a crucial role in regulating Earth’s environmental health. According to research findings published in Nature, microorganisms discovered in marine sediments and wetlands are capable of “breathing” iron minerals to eliminate toxic sulfide from their surroundings.

Revolutionary Gold-Perovskite Catalyst Sets New Efficiency Standard in Sustainable Chemical Production

Researchers have developed a groundbreaking gold-perovskite catalyst that achieves record-high acetaldehyde yields from bioethanol at significantly lower temperatures. The new catalyst reportedly outperforms a decade-old industry benchmark while maintaining stable performance. This advancement could potentially transform sustainable chemical production methods for plastics and pharmaceuticals.

Breakthrough in Sustainable Chemical Production

Scientists have reportedly developed a revolutionary catalyst that significantly advances green chemistry by converting bioethanol into valuable chemicals with unprecedented efficiency. According to reports published in the Chinese Journal of Catalysis, the new gold-perovskite catalyst achieves 95% acetaldehyde yield at 225°C, breaking a performance record that has stood for over ten years.
