Andrew Hudson-Smith demonstrates a technology which allows the memory of an article to be revealed. A mobile phone reads a code on the article. This is sent to a website and the history is sent back to the user. Further application is the ability of something inanimate, such as a bus stop, to send a message to the site saying someone’s property had been left behind.

Is monogamy unnatural? - The Science Show - ABC Radio National (Australian Broadcasting Corporation)
Or, as Dr Chris Ryan’s talk at the Sydney Opera House was entitled: ‘If you want fidelity, get a dog’. He reviews the enjoyment of sex, evidence from prehistory, and even the charming behaviour of bonobos, to suggest that conventional monogamy is but a blip in human history. And, basically, doesn’t work.

Lawrence Krauss discusses nothing - The Science Show - ABC Radio National (Australian Broadcasting Corporation)
Nothing is a deep concept. It’s been the basis of much argument. So is empty space nothing? Apparently not! There are atoms there, there is radiation. Space according to Krauss is unstable. Combined with gravity, empty space can produce real particles. So where did the space come from? When quantum mechanics is applied to space, its properties say that space can fluctuate in and out of existence. So from no space, can space come and time within it? And there are even more forms of nothing.
Lawrence Krauss discusses his ideas surrounding nothing, and these are explored further in his book, A Universe From Nothing. He says the exciting thing about science is it makes us reassess our views and question our definitions.
Buildings old and new capable of big energy savings - The Science Show - ABC Radio National (Australian Broadcasting Corporation)
Most buildings are capable of large savings in energy consumption.
The building sector is seen as being able to offer great reductions in energy use and so reductions in carbon emissions. In the UK the residential sector is considered as being able to offer a further 30% reduction over the next decade. Alex Summerfield describes a new approach to measuring energy use in buildings and the savings that are anticipated.
