Organised by the think tank International Institute for Strategic Studies, the Shangri-la Dialogue has traditionally been anchored by the US and China, which have been jostling for power in the region.This year China has sent a lower-level delegation and scrapped its speech. In the absence of a strong Chinese presence, the dialogue has been dominated by criticism and questions of Beijing posed by the US and its allies.

On Sunday morning, Marles asserted that "what we have seen from China is the single biggest increase in military capability and build up in conventional sense, by any country since the end of the Second World War".It is not just the size of the military build-up that concerns other countries, he told reporters."It's the fact that it is happening without strategic reassurance. It's happening without a clear strategic intent on the part of China… what we want to see is strategic transparency and strategic reassurance be provided by China, and an understanding of why it is needed to have such an extraordinary military build-up."

He cited Australia as an example of such transparency, noting that Canberra makes public its national defence strategy and defence reviews, and makes it "utterly clear" that when they build up their defences it is for Australia and Asia's security."So there is total strategic clarity and assurance that is being provided by Australia to our neighbours, to the region, to the world. That's what we would like to see," he said.

Answering a question on a

conducted near Australia and New Zealand's waters in February, Marles said that while it was "disruptive, and we believe that it could have been done in a better way", ultimately "China was acting in accordance with international law".So what actually is consciousness?

The short answer is that no-one knows. That's clear from the good-natured but robust arguments among Prof Seth's own team of young AI specialists, computing experts, neuroscientists and philosophers, who are trying to answer one of the biggest questions in science and philosophy.While there are many differing views at the consciousness research centre, the scientists are unified in their method: to break this big problem down into lots of smaller ones in a series of research projects, which includes the Dreamachine.

Just as the search to find the "spark of life" that made inanimate objects come alive was abandoned in the 19th Century in favour of identifying how individual parts of living systems worked, the Sussex team is now adopting the same approach to consciousness.They hope to identify patterns of brain activity that explain various properties of conscious experiences, such as changes in electrical signals or blood flow to different regions. The goal is to go beyond looking for mere correlations between brain activity and consciousness, and try to come up with explanations for its individual components.
