Ten years ago this week Science Cafe took to the air for the first time. Adam Walton settled down with a frothy cappuccino in the cafe at Techniquest in Wrexham, and a decade long journey through the whole world of science and technology began.聽
Since October 2007, the programme has been asking scientists from across Wales and the UK, to explain their research from microscopic organisms to the birth of the universe.聽

This week the programme re-visits a couple of science stories that were making the headlines ten years ago, and updating the research with the latest findings. One of the first items on the programme was a report into the alarming shrinking of the sea ice in the Arctic, which in 2007 had reached a record low. We discover this week that the downward trend has continued and there are concerns over the rising temperatures in the Arctic ocean and its potential effects on the weather.

In the first edition of the show we interviewed Professor Sir Martin Evans who, along with two collaborators in the United States, had just been awarded a Nobel prize for his pioneering work with embryonic stem cells. That work led to the setting up of the European Cancer Stem Cell Research Institute at Cardiff University. This week we hear how that work paved the way for increasing our understanding of cancer. We also look ahead to how new gene editing techniques may lead to breakthroughs in the coming decade.

We also visit Techniquest in Wrexham to revive "Espresso Science", a regular series of short science experiments which featured in the first few series of the programme. This week we explore fun ways to generate sound waves.
