Para peneliti Australia menggunakan teknik DNA lingkungan pada sampel feses untuk mengidentifikasi habitat yang sesuai bagi Gilbert's potoroo yang terancam punah. Pekerjaan ini bertujuan untuk membangun populasi baru dari hewan marsupial tersebut, yang jumlahnya di alam liar kurang dari 150 ekor. Pendekatan ini dapat meningkatkan upaya translokasi setelah berbagai hambatan sebelumnya, termasuk kebakaran hutan yang besar.

Para ilmuwan dari Edith Cowan University dan Department of Biodiversity, Conservation and Attractions menganalisis sampel kotoran dari Gilbert's potoroo dan spesies terkait. Mereka menerapkan metabarcoding eDNA untuk menentukan jamur yang dikonsumsi oleh hewan-hewan tersebut. Metode non-invasif ini mengungkapkan adanya tumpang tindih pola makan dengan quokka, quenda, dan tikus semak, sehingga membantu menentukan area dengan sumber daya makanan yang memadai untuk lokasi relokasi di masa depan.

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.

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

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.
