  • Asparagopsis & the anthropocene - HoldFast part 2

    Asparagopsis & the anthropocene - HoldFast part 2
    Jun 10 2026

    🧑‍🎨🪸 Welcome to Part 2 of our conversation for HoldFast! You’ll like this episode if you’re curious about the thermal tolerance of kelps and a vision of the near future from a molecular ecologist, if you want a first-hand account of managing a coral restoration project during a cyclone, if you find the word ‘hydrocommons’ alluring.


    We hear from Leza Howie, Josephine Johnson and Nicole Steenhoff, three WA-based artists who have organised the HoldFast exhibition in Walyalup (Fremantle). We hear stories from Norway from Dr. Antoine Minne, dip into coral restoration with Research Director of WAMSI, Dr. Jenny Shaw, and - last but not least - we get an insight into asparagopsis (beyond the methane story!) from Tom Puddy, managing director of SeaStock.

    Creativity, community & molecular ecology - HoldFast part 1
    Jun 7 2026

    🧑‍🎨🪸 This conversation is SO full of seaweed people I had to split it into two episodes. You’ll like this part if you’re interested in kelp forests growing on ancient coral beds, Scottish seaweed mythology, seaweed robots and trumpets, biobanking, how kelp makes babies, and stories about connecting scientists with communities and artists.


    We hear from two artists - Leza Howie and Josephine Johnson - who along with Nicole Steenhoff have organised the HoldFast exhibition in Walyalup (Fremantle) WA. Also joining us are molecular ecologist Dr. Antoine Minne and Research Director of WAMSI, Dr. Jenny Shaw.

  • Compostable seaweed plastic with Sway (Alyssa Pace)

    Compostable seaweed plastic with Sway (Alyssa Pace)
    Mar 26 2026
    This one’s for anyone who doesn’t want to consume 12kg of plastic, who likes the idea of the ocean as hero not victim, who’s into zines and radical imagination and composting. We're talking seaweed bioplastic! ♻️🦋Sway is a material innovation company scaling compostable solutions for plastic made with seaweed. Their products match the performance of conventional plastics and plug into existing infrastructure - but unlike conventional plastics, Sway’s materials are made from regenerative seaweed and can be composted after use. Alyssa Pace, Sway’s Head of Marketing and Comms, is here to tell us all about it. You can find Sway at swaythefuture.com on or socials @swaythefuture, and Alyssa on LinkedIn.
