Vaporizing plastics recycles them into nothing but gas
Polypropylene and polyethylene can be broken down simultaneously. Enlarge (credit: Derek Berwin) Our planet is choking on plastics. Some of the worst offenders, which can take decades to degrade in landfills, are polypro.....»»
How to prepare for a stormy "supercharged" September
The effects of climate change have become an ominous presence in our lives, and the dramatic media monikers that accompany them—bomb cyclones, atmospheric rivers, thundersnow, black swan events, heat domes, polar vortexes—sound almost biblical......»»
Low-noise amplifiers aboard the Arctic Weather Satellite
The Arctic Weather Satellite (AWS) of the European Space Agency (ESA) was sent on its journey to a polar orbit 600 km above the Earth on August 16, 2024. On board: four low-noise amplifiers (LNAs) from the Fraunhofer Institute for Applied Solid State.....»»

Zeolite catalyst method uses microwaves to convert waste cooking oil into useful chemicals
Researchers from Kyushu University have revealed that a zeolite material called Na-ZSM-5 is effective in improving the chemical conversion of biomass into olefins—a precursor chemical that makes everything from plastics to pharmaceuticals—using m.....»»
Large theropod dinosaurs thrived near South Pole, Australian tracks show
A discovery of dinosaur tracks on Australia's southern coast—dating back to the Early Cretaceous when Australia was still connected to Antarctica—indicates that large theropod dinosaurs thrived in this polar environment, prowling the river floodp.....»»
