  • Countries, governments and companies are aligning on a need for net-zero - and this is an opportunity to rethink decarbonizing our cities.
  • There is no "one-size-fits-all" solution – each city's needs must be at the heart of developing integrated energy solutions.
  • A city can only decarbonize through collaboration between government, the private sector, and local communities.

  • In Pinduoduo's Smart Agriculture Competition, four technology teams competed with traditional farmers over four months to grow strawberries.
  • Data analysis, intelligent sensors and greenhouse automation helped the scientists win.
  • Fourth Industrial Revolution technologies such as AI are forecast to deliver huge productivity gains – but need the right governance, according to the Global Technology Governance Report 2021.

  • Bioelectronic medicine is an emerging field that focuses on manipulating the nervous system to treat diseases.
  • Clinical studies show that using electronic devices to stimulate the vagus nerve is effective at treating inflammatory diseases like rheumatoid arthritis.
  • Although it's not yet approved by the US Food and Drug Administration, vagus nerve stimulation may also prove effective at treating other diseases like cancer, diabetes and depression.

Technology & Innovation
  • A new study published by a UCL researcher has demonstrated how different types of screen time can positively (or negatively) influence young people's mental health.
  • Young boys who played video games daily had lower depression scores at age 14 compared to those who played less than once per month or never.
  • The study also noted that more frequent video game use was consistently associated with fewer depressive symptoms in boys with lower physical activity, but not in those with high physical activity levels.
