Researchers develop machine learning models for genome-based early detection and prioritization of high-risk potential zoonotic viruses.

• Scientists conclude that personal carbon allowances (PCAs) could be a component of climate change mitigation. They find that the economic recovery from COVID-19 and novel digital technology capacities open a window of opportunity for first implementations. PCAs would consist of – e.g. monetary – credit-feedbacks and decreasing default levels of per capita emissions concessions. The researchers find that recent advances in machine learning technology and "smarter home and transport options make it possible to easily track and manage a large share of individuals' emissions" and that feedback effective in engaging individuals to reduce their energy-related emissions and relevant new personalized apps could be designed. Issues may include privacy, evaluating emissions from individuals co-running multinational companies and the availability and prices of products and services.
