Tech: New advances, Threads - one week in, Kiwi firms

Technology correspondent Paul Matthews joins Kathryn to look at some of the latest impressive advances brought to market in the last few years - including "electronic skin", storing energy as heat in a "sand battery" and biological storage. He'll also look at how Meta's Threads is going, one week on - how many users does it have and how's the feedback been? And as is often the way during tough economic times, there are also bargains to be had and many have come knocking on the door of Kiwi tech companies looking to make an acquisition. Paul is chief executive of CIO Studio.
