AI Transforms Global Transport & Free Service Fights Cancer in Brazil

This week's top stories of the week include:

0:15 AI transforms global transport – AI is a major new tool in urban life, from transport to payment systems. It's now being used as a city planning aid. Professor Jinhua Zhao is the head of urban mobility research at MIT. Here are 3 ways his team is using AI to help transform cities.

4:22 Free service fights cancer in Brazil – SAS Brasil brings specialist healthcare to remote areas without having to bring the healthcare specialists themselves. SAS Brasil fits out mobile health units with AI-driven telemedicine equipment and takes them to rural areas. This approach is having a significant impact on women’s health.

8:16 What is building deconstruction – When a building is demolished, many of its high-quality materials are downcycled, crushed or processed into lower-quality materials. These end up in roads or foundations or even in landfill. Increasingly, builders are reimagining buildings as material banks, filled with reusable components. By dismantling them carefully, construction companies can preserve the value of these elements.

10:41 Scientists discover source of dark oxygen – Scientists were examining the Pacific Ocean bed when they made a startling discovery. Usually, studies of the deep sea show oxygen being consumed but in a 4km-deep stretch near Mexico, oxygen is being generated instead. It could challenge theories about how life on Earth began and cast doubt on the safety of deep-sea mining.
