The world’s population is growing, people are living longer, and industry continues to expand. These changes bring many benefits, but they can also increase risks to human health. Over time, people are exposed to many substances in the environment, some of which may be harmful. At the same time, greater industrial activity means more chemicals […]
Author: José Iriarte, Professor of Archaeology, University of Exeter From the air, you see it only through the constant jolt, tilt and shudder of the low-flying Cessna aircraft. The landscape of the Llanos de Moxos, northern Bolivia, appears as a disconnected patchwork of open grassland savannahs, forest islands and lakes. It feels random, almost unreadable […]
Author: Kovi Rose, Astrophysics PhD Candidate, University of Sydney Kovi Rose, University of Sydney A pair of stars spiralling around each other. That’s the origin of a new source of repeating radio bursts we’ve detected, called ASKAP J1745. In recent years, astronomers have been puzzling over mysterious bursts of radio signals, known as long-period transients […]
Author: Melissa Lee, Senior Lecturer, School of Mathematics, Monash University Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul Erdős in 1946. The planar unit distance problem, or Erdős problem 90, has […]
Author: Victoria Guerra-García, PhD candidate at the University of the Basque Country, Dept. of Linguistics and Basque Studies (EHU) and member of The Bilingual Mind Research Group (Gogo Elebiduna) You’re in the middle of a conversation, and suddenly the word won’t come. You know exactly what you want to say, but you just can’t retrieve […]
Authors: Sarah Foster, Program Leader, Project Seahorse and Senior Researcher, Institute for the Oceans and Fisheries, University of British Columbia and Amanda Vincent, Professor, Institute for the Oceans and Fisheries, University of British Columbia Bottom trawlers extract one-quarter of the world’s fisheries catches by weight and raise significant ecological, economic and social concerns. Given that […]
Imagine trying to build a house without a blueprint, find a shortcut through an unfamiliar city without a map, or govern a large organisation with no leaders and no meetings. It sounds impossible. Yet tiny-brained ants, working without leaders or blueprints, have been solving problems like these for millions of years – and no, the […]
Two years ago, in March 2024, I wrote in this blog about a decision that surprised many: the rejection of the Anthropocene as a formal geological epoch. After fifteen years of work by an international team of experts, the proposal to declare that we are now living in a new chapter of Earth’s history—one defined […]
Author: Howard Wiseman, Director, Centre for Quantum Dynamics, Griffith University As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would have asked him about […]
For decades, biology textbooks have repeated the same idea with almost ritual certainty: neural stem cells, the cells that fuel the birth of neurons and glia during development, live exclusively inside the brain and spinal cord. They are the architects of the central nervous system, and nowhere else. It has always seemed like an elegant […]
