The eruption of Hunga Tonga Hunga Ha‘apai in January triggered a tsunami of unprecedented proportions, impacting the entire Pacific. How did this volcanic eruption lead to a tsunami detected across the globe, including as far away as the Mediterranean? Science communicator Ellen Rykers speaks to the scientists unravelling the secrets of this rare phenomenon.
With their antler-like mandibles, Helm's stag beetles often get stuck in to one another. But they are fighting a bigger battle too - against predators and habitat loss. PhD student Luna Thomas is studying these little known endemic insects. She hopes her work will add to our sparse scientific knowledge, and maybe help some of the other native stag beetle species, some of which are critically endangered.
The New Zealand data science programme, Taiao, aims to help researchers make sense of environmental data so they can make useful predictions to guide good decisions. Claire Concannon meets the team at the University of Waikato where the programme is hosted. And a group in the Auckland Bioengineering Institute are researching a new needle-free jet injector design that they think might lead to a happier future for those with needle phobia.
PhD student Kiamaia Ellis describes crayfish as a ‘vulnerable tāonga species’. Local iwi in Tauranga believe the crayfish population is decreasing because of urban, industrial and harvesting pressures. But Kiamaia is keen to be a part of the solution, so she’s studying the resilience of pēpi kōura / baby crayfish. She wants to understand how these tiny species – that take eight years to become an adult – are able to thrive based on a kaitiakitanga or guardianship approach.
Working with the community and local schools, the Karioi Project aims to turn the tide on biodiversity loss in their area. In recent years they've rallied around the grey-faced petrel, or ōi, who they hope to help return to the maunga.
Two stories about the promise and perils of chemistry research. From a team recreating Renaissance beauty recipes in the hopes of rediscovering a 'miracle ingredient', to a researcher investigating New Zealand's deadliest synthetic cannabinoid.
The Nevis Fault is a sleeping giant fault, one that awakens only every 10,000 years or so. This week, a team of geologists use paleoseismic trenching to answer questions about this fault and to figure out the pattern of past earthquakes.
It's Prime Minister's Science Prize time! We meet some of the people awarded the 2021 prizes for their mahi.
Researchers from the University of Waikato are tackling the tricky question of how to restore native biodiversity in our urban areas.
We join Marine Science PhD student Namrata Chand on her Autumn field work collecting seaweed samples to learn more about this 'underdog of the ocean'.
