The Gaza Strip is one of the most densely-populated tracts of land in the world. In addition to the ongoing violence there, it has an unemployment rate of more than 40 percent, and problems with access not only to clean water and electricity, but also basic construction supplies. The United Nations has described the situation there as “a constant humanitarian emergency”. Despite these challenges, a young Gazan engineer has developed a new and innovative way of making bricks, which she hopes could make Gaza less dependent on outside help. She uses rubble and ash to create a cheap, light brick that can be made locally. World Hacks goes to visit the factory and to learn more about how this award-winning new brick, called ‘Green Cake’, could make a difference.Presenter: Harriet Noble Reporter: Elizabeth DaviesPhoto Caption: Green Cake Photo Credit: BBC

More than three million people in Nigeria are living with HIV, but only about 10% of the population has ever taken an HIV test. Talking about sex is a taboo subject and sexual health clinics are not popular places to be seen. Other sexually transmitted diseases, such as Hepatitis B and Syphilis, are on the rise among young people. But a Nigerian entrepreneur called Florida Uzoaru thinks she has a millennial-friendly solution to sexual health. Her start-up is giving people the option to anonymously test themselves at home. Secret packages, sent by courier, contain a pick ‘n' mix of self-test blood kits, contraception or the morning after pill. Customers buy everything online and receive counselling and assistance via WhatsApp. But can bypassing the healthcare system solve the problem?
