大象传媒

New figures show one in every 30 children is homeless in the US. Dr Carmela DeCandia from the National Center on Family Homelessness describes the scale of the problem and explains why the number is often under-reported. We also speak to the 大象传媒's Rob Cameron in Prague where the president of the Czech Republic has been pelted with eggs by protesters at a ceremony to mark the 25th anniversary of the Velvet Revolution.

As Airbus files a patent claim for a revolutionary airplane design, we hear from Tom Irvine, formerly at Nasa and now at the American Institute of Aeronautics and Astronautics about why there are so many thousands of speculative applications. The 大象传媒's Rahul Tandon joins us from Calcutta to talk about Narendra Modi's 'rock star' welcome during his tour of Australia. We are joined throughout the programme by two guests on opposite sides of the Pacific - David Kuo in Singapore and Cecily McMillan in New York City.
