Professor Aviv Regev from MIT is one of the leaders of The Human Cell Atlas, an ambitious project that aims to map the 35 trillion cells in our body that make us who we are. It's been described as a Google Maps for the human body. Cataloguing every human cell, which will be done by an international team of labs, will provide a much better understanding of what we're actually made up of, and how diseases start and develop.

How video games are changing football, a visit to a doll hospital, using bike parts to build an open source wheelchair, and should we be worried about acrylamide in our food?

Janna Deeble grew up in Kenya and saw the problem for himself. His SafariSeat is a rugged, low cost wheelchair made from bicycle parts, that can be assembled by just about anyone using easy, open source plans.

Acrylamide's a chemical produced when starchy foods are cooked at high temperatures, so we ingest low doses of it in things like chips, toast, cereal and instant coffee. It's been in the news in Europe, where the European Union's just decided it won't go ahead with plans to restrict acrylamide levels in processed food, supposedly after some serious lobbying by the food industry. But does it need to be in our food at all, and should we be worried about it? Ian Shaw, Professor of Toxicology at The University of Canterbury, weighs up the evidence.
