To study how psychedelic drugs can help treat mental illness, Dr Paul Liknaitzky is giving Australian trial participants high doses of psilocybin – a hallucinogenic compound found in some fungi.

With summer upon us, so comes outdoor living, barbecues .. and mosquitoes. Dr Maria Elena De Obaldia from Rockefeller University and the Howard Hughes Medical Institute is the lead author of a study into why mosquitoes specifically seek out some people.

A dud batch of aviation gas has sent ripples through the airline sector - they've been told they'll be supplied with less fuel than usual in the coming weeks - right at the busiest travel time of the year. Last month, the government announced an increase in the amount of petrol, jet fuel and diesel that importers and wholesalers must hold and that it would boost its own reserves of diesel in an effort to improve the country's ability to weather fuel shocks. Energy and Resources Minister Megan Woods says the government is still investigating storage facility options and the stocks are unlikely to be accumulated until late 2023 or early 2024. Are the new minimum storage requirements adequate when one dud batch of av-gas can have such an impact, and when Marsden Point no longer has refining capability? Kathryn speaks with Simon Terry, Executive Director Sustainability Council, who has serious misgivings about the way the government has approached the issue.

Te Riu-a-Maui - or Zealandia - is the world's eighth continent and is right underneath us. It is the world's youngest, smallest, thinnest and most submerged continent, with about 94 per cent of it lying underwater. Geologist with GNS Science, Dr Nick Mortimer, has been at the forefront of discoveries about the hidden continent. He has recently been awarded a $100,000 James Cook Research Fellowship from Royal Society Te Aparangi to continue his work on Zealandia's geological make-up and ancestry. He was elected a Fellow of the Royal Society Te Aparangi in 2017, and in 2020 received a Science New Zealand Individual Lifetime Achievement Award. Dr Mortimer says it has taken hundreds of years for the science behind the discovery of the continent to mature - and there is still much to explain and communicate about Zealandia.
