The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.]]> Wed, 25 Jan 2023 19:15:50 +0200 https://api.follow.it/track-rss-story-click/v3/eePbbD1UY3eUC08XfTHqipVjH6qdYdAk https://api.follow.it/track-rss-story-click/v3/eePbbD1UY3fC2dCcNDRuDuT5HJgy6HUf Scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.]]> Wed, 25 Jan 2023 15:58:57 +0200 https://api.follow.it/track-rss-story-click/v3/eePbbD1UY3fC2dCcNDRuDuT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/eePbbD1UY3cxe8wowsRtgZs0ohxaO6Yr Engineers have demonstrated a simple computational approach for supporting the classification performance of neural networks operating on sensor time series.
