Small doses of caustic soda increase biogas production from banana waste

Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces reagent consumption and, consequently, diminishes process costs and minimizes the risk of inhibiting the microorganisms responsible for the process.

Beauty and the Brain

Dr Tiffany Jenkins asks what our brains can tell us about art. Can there ever be a recipe for beauty? Or are the great works beyond the powers of neuroscience? She talks to Professor Semir Zeki of University College London, the first person to coin the term, neuroaesthetics, about what happens in the brain when people in a scanner see paintings or hear music. Professor Gabi Starr at New York University tells Tiffany Jenkins why she thinks there are parts of the brain that light up when we like an art work. Tiffany visits Christie's auction house to explore whether the best art always commands the best prices.She also talks to Martin Kemp, Emeritus Professor of Art History at Oxford University, about our different responses to authentic paintings and to fakes. And Tiffany discusses with art critic JJ Charlesworth why neuroscience is having an influence in some areas of art appreciation.Picture: The reflection of trees in water, Credit: Getty

Mark Miodownik

Mark Miodownik's chronic interest in materials began in rather unhappy circumstances. He was stabbed in the back, with a razor, on his way to school. When he saw the tiny piece of steel that had caused him so much harm, he became obsessed with how it could it be so sharp and so strong. And he's been materials-mad ever since. Working at a nuclear weapons laboratory in the US, he enjoyed huge budgets and the freedom to make the most amazing materials. But he gave that up to work with artists and designers because he believes that if you ignore the sensual aspects of materials, you end up with materials that people don't want. For Mark, making is as important as reading and writing. It's an expression of who we are, like music or literature, and 'everyone should be doing it'. To this end, he wants our public libraries to be converted into public workshops, with laser cutters and 3 D printers in place of books.Image: Mark Miodownik, BBC Copyright
