When astronomers in the eighteenth century first turned powerful telescopes toward the Milky Way, they noticed something puzzling: tight, spherical swarms of stars scattered across the sky. Now we know that each contains hundreds of thousands of suns packed into a region just a few dozen light-years across. These objects, known today as globular clusters […]
Author: Tara Djokic, Scientific Officer, Palaeontology, Australian Museum; UNSW Sydney Hidden beneath farmland in the central tablelands of New South Wales lies one of Australia’s most extraordinary fossil sites – McGraths Flat. It dates back between 11 million and 16 million years into the Miocene epoch, a time when many of today’s familiar plants and […]
When did something like us first appear on the planet? It turns out there’s remarkably little agreement on this question. Fossils and DNA suggest people looking like us, anatomically modern Homo sapiens, evolved around 300,000 years ago. Surprisingly, archaeology – tools, artefacts, cave art – suggest that complex technology and cultures, “behavioural modernity”, evolved more […]
The cover of this post probably shows the world’s most famous carnivorous plant (Figure 1). It´s name is Audrey II and it appeared in the music film “Little shop of horrors”, directed by Franz Oz in 1986 adapting the film “The Little Shop of Horrors” directed by Roger Corman in 1960. Audrey II is a […]
The idea of a living fossil is rather intuitive. We think that a kind of organism deserves that denomination if it has been living in the planet during a very large period of time apparently without any change. A well known example of living fossil is the Ginkgo tree (Ginkgo biloba) because, although it is […]
When energy storage is discussed in the context of the energy transition, the conversation almost invariably turns to electricity. Solar and wind power have made the temporal mismatch between energy production and energy demand one of the defining challenges of low-carbon energy systems, and technologies capable of storing electrical energy have consequently become central to […]
Author: Chris Kirkland, Professor of Geochronology, Curtin University In the Pilbara of Western Australia, some of Earth’s oldest rocks lie beneath the sky, as they have for billions of years. They are dark, weathered volcanic rocks, close to 3.5 billion years old, cut by veins and stewed by deep time. Their survival is remarkable. Most […]
One of the principal values of philosophical thought has traditionally been the promotion of conceptual clarity: helping us to understand as well as possible what it is we are thinking when we think what we think. In the debate over the moral aspects of the limits of life, it is therefore important to reflect on […]

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing “icehouse” periods and warm “greenhouse” states. Scientists have long linked these climate changes to fluctuations in atmospheric carbon dioxide. However, new research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously […]
