New catalyst turns greenhouse gases into hydrogen gas

A new nanocatalyst that recycles major greenhouse gasses, such as carbon dioxide (CO2) and methane (CH4), into highly value-added hydrogen (H2) gas has been developed. This catalyst is expected to greatly contribute to the ...

Graphite sheets to help next-gen smartphones to keep their cool

It can be a significant challenge to cool the powerful electronics packed inside the latest smartphones. KAUST researchers have developed a fast and efficient way to make a carbon material that could be ideally suited to ...

Graphene: Making a wonder material more wonderful

Graphene is a form of the chemical element carbon. Well-known forms of carbon include the world's hardest material, diamond, and the soft black material known as the "lead" in a pencil, which is graphite. Graphite can be ...

Marine extremophiles: The basal level of the food chain

In nutrient-poor deep-sea sediments, microbes belonging to Archaea have outcompeted bacterial microorganisms for millions of years. Efficiently scavenging dead cells makes them the basal producers in the food chain.

Ancient wetlands provide new insight into global carbon cycle

Scientists have unearthed and pieced together evidence on more than 1,000 ancient wetland sites from across the globe that are presently covered by fields, forests and lakes. Although vanished from the Earth's surface, these ...

Mars terraforming not possible using present-day technology

Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term ...
