Plastics found in electronic waste (e-waste) are rarely recycled due to their complex composition and hazardous additives, but scientists at NTU Singapore have developed a new use for them – by repurposing them as an alternative to the plastics used in laboratory cell culture containers, such as petri dishes.

Researchers in Japan have found an energy-efficient way to convert the chief greenhouse gas carbon dioxide (CO2) into useful chemicals. 

The tiny, pale surf clam about the size of a fingernail that most people have seen and collected on beaches around the world holds clues in its shell to Earth’s past. 

The supply of farmed seafood such as salmon and mussels are projected to drop 16 per cent globally by 2090 if no action is taken to mitigate climate change, according to a new UBC study.
