This week's top stories of the week include:

0:15 This start-up has redesigned the wind turbine – It’s designed by US start-up Airloom. Which says it can generate the same amount of energy as a traditional turbine but at a fraction of the cost and size. It’s much smaller and uses far fewer materials, making it almost 10 times cheaper to build. Its design can generate electricity at one-third the cost of standard wind turbines. Its turbines should take up less space, too as conventional turbines have to be distanced from one another.

1:45 Cutting salt works as well as medication – Scientists have found that reducing salt intake by just 1 teaspoon per day can lower blood pressure as much as specific drugs for that purpose. Researchers put 213 people aged 50-75 on either a high- or low-sodium diet. After a week, the two groups swapped. The low-sodium diet led to a swift and pronounced drop in blood pressure roughly equal to a ‘first-line blood-pressure medication’, say the authors.

3:27 What is climate justice? – Climate change is a global crisis, but its impacts are felt unequally. For many, it's not just about rising temperatures and melting glaciers, but about the very survival of their communities.

6:11 How AI will open the world to disabled people – Victor Pineda, a Hispanic man in a wheelchair and using a machine to help him breathe, shares his experience of growing up in a world that wasn't designed for him. Denied education in his home country due to his disability, he found an opportunity in the US, where laws protected his right to learn. He sees AI as a chance to create customized learning experiences for diverse learners, a stark contrast to his exclusionary past.
