Australian researchers are using environmental DNA techniques on feces samples to identify suitable habitats for the critically endangered Gilbert's potoroo. The work aims to establish new populations of the marsupial, which numbers fewer than 150 in the wild. The approach could improve translocation efforts after past setbacks including a major bushfire.

Scientists from Edith Cowan University and the Department of Biodiversity, Conservation and Attractions analyzed scat samples from the Gilbert's potoroo and related species. They applied eDNA metabarcoding to determine the fungi the animals consume. This non-invasive method revealed dietary overlaps with quokkas, quendas and bush rats, helping pinpoint areas with adequate food resources for future relocation sites.

Two marsupials thought extinct for 6000 years found alive

Scientists have confirmed the survival of two marsupial species long believed extinct, thanks to assistance from Indigenous communities in Indonesia. The ring-tailed glider and pygmy long-fingered possum were discovered in Papua's Vogelkop peninsula. Their habitats, however, face serious threats from logging.

Scientists analyze Darwin's 200-year-old specimen jars without opening them

Researchers have developed a laser technique to examine the contents of Charles Darwin's original specimens from the Galápagos Islands without disturbing the nearly 200-year-old jars. The method, known as Spatially Offset Raman Spectroscopy, reveals the chemical makeup of preservation fluids inside sealed containers. This breakthrough aids museums in preserving delicate collections worldwide.

Brazil fossil reanalysis challenges early animal origins

Scientists have determined that structures once seen as traces of tiny animals in 540-million-year-old Brazilian rocks are actually fossilized communities of bacteria and algae. The reexamination uses advanced imaging to reveal preserved cells and organic material.

DNA study supports human arrival in Australia 60,000 years ago

9 Mwezi wa nne, 2026 Imeripotiwa na AI

Scientists have found genetic evidence that modern humans reached New Guinea and Australia around 60,000 years ago, backing the long chronology over more recent estimates. The international team, led by researchers at the University of Huddersfield and the University of Southampton, analyzed nearly 2,500 mitochondrial DNA genomes from Aboriginal Australians, New Guineans, and Southeast Asian populations. Their work suggests early migrants used at least two routes through Southeast Asia.
