Limestone, iron reveal puzzling extreme rain in Australia 100,000 years ago

Almost one-sixth of Earth’s land surface is covered in otherworldly landscapes with a name that may also be unfamiliar: karst. These landscapes are like natural sculpture parks, with dramatic terrain dotted with caves and towers of bedrock slowly sculpted by water over thousands of years. | Photo Credit: Matej Lipar/The Conversation Almost one-sixth of Earth’s land surface…

Ancient human DNA from a South African rock shelter sheds light on 10,000 years of history

New technology is making it possible to keep learning more from previously discovered archaeological material. Oakhurst offered an opportunity to reconstruct the genomes of the site’s inhabitants through time, and to assess their genetic relationships to people living in the region today. | Photo Credit: Shutterstock Oakhurst rock shelter is an archaeological site near the town…

Could rotating black holes be the wind turbines powering the distant future?

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a…

Scientists are using ancient DNA to reveal the Iberian lynx’s ‘weapon’ against extinction

Scientists are using ancient DNA to reveal the Iberian lynx’s ‘weapon’ against extinction

Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a “genetic database” to fall back on to adapt to environmental change. The Iberian lynx (Lynx pardinus) is no stranger to this reduction in diversity. Human…
