Peter Griffin on a US report that shows how Facebook, Twitter and other social networks are selling information about us to law enforcement agencies. Also newly released advertising figures show how much clout Facebook has in New Zealand's media landscape. And a horrible week for Samsung, with the recall of 2.5 million Galaxy Note 7 handsets over a fault that makes them spontaneously combust.

Science writer Carl Zimmer looks at "the latest volley in a long-running debate among scientists about the human life span".

Dr Chris Smith of The Naked Scientists with the news that scientists use gene editing to find a potential cure for the inherited blood disorder sickle cell anaemia, and a way to use brain implants to restore a sense of touch to people with spinal injuries.

Touching the universe: astronomy for the blind, Google take over your home (and your phone), avoiding mid-air collisions using 'the Budgie Paradox', and half holes and baffling bagels: the 2016 Nobel science prizes explained.

How 3D printed models can be used to teach blind students about astronomy. This Way Up visits Manurewa High School in Auckland to experience 'tactile astronomy' in action.

Technology news with Peter Griffin and Google launches its new Pixel phone and a digital home assistant called (you've guessed it!) Home. Now search is anywhere and everywhere.

Professor Mandyam (Srini) Srinivasan from the University of Queensland has recruited a high-flying team of 10 budgies and is flying them down tunnels to try to make them bump into each other. He's trying to work out why birds don't collide when they fly, and then use this knowledge to make our planes and drones safer.

Dr Chris Smith of The Naked Scientists has been trying to make sense of the work behind the Nobel science prizes announced this week. So what's been recognised, why is it important, and what on earth is topology ("work so baffling it had to be described using bagels"- The Daily Telegraph)?!

Sending second-hand fishing equipment to the Pacific, how to get rid of agapanthus, and a new hi-def map of the galaxy.

17-year-old Finn Ross was on holiday in Fiji and saw how local people were struggling with old or broken fishing gear, and the problems this was causing. So Finn and his mate Max Lichtenstein decided to do something about it. They set up a charity called Let Them Fish that's collecting hundreds of second-hand reels and rods, kilometres of fishing line, and loads of diving stuff here in New Zealand and sending it off to people who need it in Fiji and Tonga.
