Nature's color palette explains why everything we see is a mix of red, yellow, green and blue

Biologists and linguists alike have long puzzled over the universal human tendency to see and name colors as a combination of four "pure" hues—red, yellow, green and blue.

Chris Toumazou

European Inventor of the Year, Chris Toumazou, reveals how his personal life and early research lie at the heart of his inventions. As chief scientist at the Institute of Biomedical Engineering at Imperial College London, Chris inspires engineers, doctors and other scientists to create medical devices for the 21st Century. Applying silicon chip technology, more commonly found inside mobile phones, he tackles seemingly insurmountable problems in medicine to create devices that bridge the electronic and biological worlds - from a digital plaster that monitors a patient's vital signs to an artificial pancreas to treat diabetes. His latest creation, coined a 'lab on a chip', analyses a person's DNA within minutes outside the laboratory. The hand-held device can identify genetic differences which dictate a person's susceptibility to hereditary diseases and how they will react to a drug like warfarin, used to treat blood clots.

The Making of the Moon

It is the nearest and most dominant object in our night sky, and has inspired artists, astronauts and astronomers. But fundamental questions remain about our only natural satellite. Where does the Moon come from? Although humans first walked on the Moon over four decades ago, we still know surprisingly little about the lunar body's origin. Samples returned by the Apollo missions have somewhat confounded scientists' ideas about how the Moon was formed. Its presence is thought to be due to another planet colliding with the early Earth, causing an extraordinary giant impact, and in the process, forming the Moon. But, analysing chemicals in Apollo's rock samples has revealed that the Moon could be much more similar to Earth itself than any potential impactor. Geochemist Professor Alex Halliday of the University of Oxford, and Dr Jeff Andrews-Hanna, Colorado School of Mines – who is analysing the results from Nasa's Gravity Recovery and Interior Laboratory (GRAIL) lunar mission – discuss the theories and evidence to-date. Are we Going Back? Settling the question of the Moon's origin seems likely to require more data – which, in turn, requires more missions. BBC Science correspondent Jonathan Amos tells us about the rationale and future prospects for a return to the Moon, including the Google Lunar XPrize. As the Moon's commercial prospects are considered, who controls conservation of our only natural satellite? If commerce is driving a return to the Moon, who owns any resources that may be found in the lunar regolith? Dr Saskia Vermeylen of the Environment Centre at Lancaster University is researching the legality of claiming this extra-terrestrial frontier. (Photo: Presenter Lucie Green. BBC copyright)
