A New Zealand technology firm in the race to produce the world's first methane-busting cattle feed supplement made from seaweed is planning to grow and process seaweed in Southland. CH4 Global was founded by a group of local tech and bioscience entrepreneurs, and has been working with Australia's national science agency CSIRO,  developing the product made from Asparagopsis armata - a native red seaweed which grows in New Zealand and South Australian waters.  Co-founder Nick Gerritsen says trials of the product on sheep, dairy cows and feedlot beef cows in the US and in Australia show methane reduction effects ranging from 60 per cent to more than 90 per cent. CH4 Global has just received $500 thousand dollars from the Provincial Growth Fund to establish seaweed processing in Southland.

Researchers are warning that as more and more consumers switch to electric vehicles, better methods of recycling their batteries are urgently needed to prevent a mountain of waste. One million EVs sold around the world in 2017 including 546 here, up from 63 in 2016. In September this year, 605 electric and plug-in hybrid vehicles were sold in New Zealand. Research from the University of Birmingham say that when the batteries from the 2017 fleet begin to wear down in around 20 years, they'll create 250 thousand tonnes of waste - and that's just from that one year. Kathryn talks with the study's lead author, Gavin Harper, a  research fellow at the University of Birmingham's Faraday Institution.

"Why Women Have Better Sex Under Socialism" is a book with a seductive title but contains a serious argument. In it Kristen Ghodsee explains how, when done right, socialism offers more opportunities for women to live better lives than unregulated capitalism. She got to this conclusion having researched the transition from communism to capitalism in eastern Europe, which created, she says, a perfect laboratory to investigate. Kristen Ghodsee, a professor of Russian and East European Studies at the University of Pennsylvania, will be appearing at the New Zealand Festival of the Arts with Marilyn Waring and Ngahuia te Awekotuku for a panel discussion on 'Sex, politics and Gender'.
