This week Adam discovers what's really going on during the dawn chorus, which is at its most musical at this time of the year. Greener cars are also on the menu - and we consider the recent comments about extra-terrestials made by Stephen Hawking.

ET hang up...

Professor Hawking put the cat among the pigeons last week by suggesting that if ET ever comes calling, we should keep a low profile. If there is another life form out there, he suggests, it's more likely to view us as lunch rather than become our best buddy. Presenter Adam Walton mulls this over with astronomer and astrobiologist Martin Griffiths, from the University of Glamorgan.

Vroom 1

The Bangor-born engineer Richard Parry Jones was once known as 'Ford's Secret Weapon', for his contribution to the car industry and his work on the Ford Focus, Fiesta and Ka. He talks to Science Cafe reporter, Jeremy Grange, about his career - and the ongoing mission to create greener cars.

Vroom 2

Sticking with the subject of cars and engineering, Adam Walton drives to Glyndwr University in Wrexham to meet some of the students who hope to follow Richard Parry Jones into car industry.

Musical mornings

The dawn chorus is at it peak at this time of the year, but it's so much more than a musical interlude to cheer the start of our day. For the birds themselves it's part of a life-or-death competition to defend territory and find a mate. Adam hears why a good repertoir of songs really does give a feathered friend the advantage.
