A few days ago, my five-year-old daughter rushed home from school excitedly telling me about a volcano that had erupted for “the first time since mummy was little” in a “country called Aeee”. I was pretty thrown. But a quick Google search revealed there was lava spilling from the world’s largest volcano, Mauna Loa.

Now, many of you will know that Mauna Loa is located on the Big Island of the state of Hawaii, not “a country called Aeee”. But, as I say, she’s five. I was delighted she was so interested in what was happening. I was also thrilled then, when Conversation colleagues in the US published this piece explaining what is so unusual about this and other volcanoes in the Hawaii zone. It's author, Gabi Laske, is a geophysicist at the University of California-San Diego who led one of the first projects to map the deep plumbing that feeds the Hawaiian volcanoes.

So, my horizons have been expanded by my daughter. It’s a regular occurrence these days. But it seems my brain may have been altered by her very arrival, and the degree to which I have engaged with her since. This team of researchers in California and Spain found “several significant changes in the brains of fathers from prenatal to postpartum periods.

Meanwhile, a spectacular new gallery has opened in Sydney.

A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.

Neuroscientists know that pregnant mothers’ brains change in ways that appear to help with caring for a baby. Now researchers have identified changes in new fathers’ brains, too.

‘A three-storey, luminous birdcage with suspended hanging gardens and an extensive crypt below’: Sydney Modern is open at last

Sydney Modern at the Art Gallery of New South Wales is a spectacular achievement – but going forward, funding is required for more than rammed earth, glass, bricks and mortar.
