Each week, we scour the worlds of innovation, tech for good and social impact to bring you seven of our top stories…

1. Spanish start-up Bioo is developing batteries that generate electricity from energy released from decomposing organic matter, which are proving invaluable for the agricultural industry where they are used to power sensors on farms.
2. An international non-profit, “Techfugees” is empowering refugees with training in AI skills in Lebanon and developing an e-commerce platform for internally displaced entrepreneurs in Nigeria.
3. In Dorset, sensors will be installed to monitor behaviour and electricity usage of people living in social care in a pilot aiming to automatically register improvements in personal independence within the home or, conversely, flag up activity that might indicate a problem.
4. Cambridge astronomers have identified new hydrogen-rich exoplanets that could potentially hold signs of life.
5. ‘Wind Catching Systems’ is developing an offshore wind power generator which could produce enough renewable energy to power 80,000 homes, harnessing energy from higher winds speeds than traditional turbines.
6. Scientists are developing a new AI system to accurately predict ice loss in the Arctic, which could help underpin a greater early-warning system to protect coastal communities and Arctic wildlife.
7. A new drug treatment approach could help reduce child malaria death by 70% following a successful trial involving 6,000 children in Burkina Faso and Mali.
