Lightning cracks the night sky. A popping sound fills the air. The power is out. The city is dark. But then the street lamps silently flicker back on. A back-up battery has sprung into action. The city can keep running.

This could be the near future. Japanese firm PJP Eye has developed a backup battery that works when all else fails. It works by burning a small amount of waste cotton at high temperature.¹ The invention of sustainable power sources is reason for cheer. 

There are many others. In the last few weeks, representatives from 27 countries have agreed to tackle the risk of AI, the European Union has voted to halve pesticideA substance used for destroying insects or other organisms. use and dengueA debilitating viral disease transmitted by mosquitoes. has been almost eradicated from ColombiaA country in South America with a population of just over 50 million. .²

The number of people living in extreme poverty has decreased.⁴ We have made enormous strides in disease prevention. It took scientists decades to develop the flu vaccine, but we created and distributed a working vaccine for Covid-19 in less than a year.⁵

The negative tone of the news might just be good business. One research project has found that each negative word in a headline increases clicks by 2%.⁶ Focusing on the bad gives news websites more hits. For news sources, bad news is good news.
