Exiguobacterium degradation of polystyrene: Enlisting bacteria in the war against plastic
Polystyrene is a chemically stable recalcitrant plastic that pollutes many natural environments. Unfortunately, few mechanisms can break down this man-made polymer into its naturally occurring components. Research into the polystyrene-digesting capabilities of the bacteria genus Exiguobacterium sp RIT 594 by Dr André Hudson and his team at the Rochester Institute of Technology in New York, USA, has uncovered the specific […]
Plastic Free July® 2022
Plastic pollutes our land, our airways, and our oceans. This month is Plastic Free July® 2022 – a global initiative to encourage everyone to eliminate plastic use for one month. The event, run by Plastic Free Foundation, invites us all to be part of the solution. Each year, over 100 million people in 190 countries take part. We’ve picked the […]
Omnipresent microplastic
Microplastics have invaded every crevice, nook, and cranny on our planet and they are here to stay. Remember that plastic bottle you threw away back in the ‘80s? Well, it hasn’t disappeared – instead, it has fragmented into a million tiny pieces, which are now swimming in every ocean, infiltrating the soil in farms around the world, and even circulating […]
Insights into the complex world of amorphous solids
Solid materials come in many different varieties, from highly rigid, ordered crystalline materials to the more slippery, irregular world of amorphous solids. While we have good theories for understanding the properties and behaviour of crystalline materials, the disorder in the structure of amorphous solids makes their fundamental physics complicated to understand. However, Professor Hideyuki Mizuno at the University of Tokyo […]

Technological leapfrogging the global energy crisis: How can changing the role of science in developing countries help with an oncoming climate catastrophe?
In 1975, the Brazilian government launched the National Alcohol Program (NAP) with the sole aim of relieving the country’s crushing dependence on fossil fuels with a move to cleaner ethyl-alcohol based fuels – and, thanks to researchers like Professor José Goldemberg, of the University of São Paulo, the program was an overwhelming success. Combining the country’s own natural resources with technological leapfrogging – […]
