Ancient bird droppings reveal a hidden extinction crisis

Researchers from the University of Adelaide, New Zealand’s Manaaki Whenua-Landcare Research and University of Auckland have discovered that more than 80 per cent of parasites detected in kākāpō poo prior to the 1990s are no longer present in contemporary populations. The project used ancient DNA and microscopic techniques to sample…

AI cracks a meteorite’s secret: A material that defies heat

Crystals and glasses have opposite heat-conduction properties, which play a pivotal role in a variety of technologies. These range from the miniaturization and efficiency of electronic devices to waste-heat recovery systems, as well as the lifespan of thermal shields for aerospace applications. The problem of optimizing the performance and durability…

Radar that could find life on Europa just nailed its first big test

NASA’s largest interplanetary probe tested its radar during a Mars flyby. The results include a detailed image and bode well for the mission at Jupiter’s moon Europa.

Ultra-hot Jupiter in death spiral may reveal how rocky worlds are born

Macquarie University astronomers have tracked an extreme planet’s orbital decay, confirming it is spiralling towards its star in a cosmic death dance that could end in three possible ways. The ultra-hot Jupiter exoplanet TOI-2109b, located 870 light-years from Earth, completes an orbit around its star in just 16 hours –…

Underground life on Mars? Cosmic rays could make it possible

A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar system. The research shows that cosmic rays may not only be harmless in certain environments but…
