Study shows green roofs could reduce indoor air pollution

Green roofs – roofs that are planted with vegetation—may improve the indoor air quality of commercial buildings by cutting the amount of ozone coming into the buildings from the outside, according to new research from ...

Bacteria that oxidizes methane found in common soil

A team of researchers with members from Norway, Austria, Russia and Germany has found a kind of bacteria that oxidizes methane. In their paper published in Proceedings of the National Academy of Sciences, the group describes ...

Shrinking the carbon footprint of a chemical in everyday objects

The biggest source of global energy consumption is the industrial manufacturing of products such as plastics, iron, and steel. Not only does manufacturing these materials require huge amounts of energy, but many of the reactions ...

Carbon-negative power generation for China

If we're going to limit global temperature increases to 2 degrees above pre-industrial levels, as laid out in the Paris Climate Agreement, it's going to take a lot more than a transition to carbon-neutral energy sources such ...

Just how much does enhancing photosynthesis improve crop yield?

In the next two decades, crop yields need to increase dramatically to feed the growing global population. Wouldn't it be incredibly useful if we had a crystal ball to show us what are the best strategies available to increase ...

Carbon dioxide to methanol conversion

NUS chemists have developed a highly efficient nanostructured catalyst based on zinc and silver that can convert carbon dioxide, an environmental pollutant and greenhouse gas, to methanol for use as chemical feedstock and ...
