The Happy Pod: I invented a way for my brother to communicate

Ari wanted to help his brother Ben engage with the world after he lost the ability to walk, talk or move his hands. So he designed and built him a bespoke communication and entertainment system - allowing him to chat, go online, watch TV or play video games with just two buttons. Also: the endangered Mexican amphibian found in a river in the UK. Experts say the young girl who captured the axolotl probably saved its life. The women using their own experiences with breast cancer to tackle cultural taboos about the disease in Uganda, and encourage others to get treatment. After the Boston marathon, we hear from an elite female athlete hoping to inspire others by running the race while 22 weeks pregnant. And we find out why two runners stopped to help another who collapsed within sight of the finish line. Plus a statue honouring a giant rat who sniffed out landmines in Cambodia; and why a nature festival has had to clarify that visitors should come fully clothed. Our weekly collection of inspiring, uplifting and happy news from around the world. Presenter: Holly Gibbs. Music composed by Iona Hampson Image credit: NARBE House
