STORY: Aussie researchers discover 380-mln-year-old heart of ancient fish DATELINE: Sept. 19, 2022 LENGTH: 00:00:56 LOCATION: SYDNEY, Australia CATEGORY: SOCIETY SHOTLIST: 1. various of constructed three-dimensional images of the fish STORYLINE: Aussie researchers have discovered a 380-million-year-old heart -- the oldest ever found -- in an ancient jawed fish, alongside a separate fossilized stomach, intestine and liver, providing new insights into biological evolution. Kate Trinajstic, the lead researcher from Curtin University's School of Molecular and Life Sciences and the Western Australian Museum, said the discovery was remarkable, given that soft tissues of ancient species were rarely preserved, and it was even rarer to find 3D preservation. "As a palaeontologist who has studied fossils for more than 20 years, I was truly amazed to find a 3D and beautifully preserved heart in a 380-million-year-old ancestor," Trinajstic said in a statement.

In a study published on Monday, researchers from the Australian National University (ANU) and Curtin University called for a major rethink of Australia's fire prevention strategies. Researchers, led by David Lindenmayer from ANU's Fenner School of Environment and Society, reviewed existing analyses of bushfires in Australia as well as Brazil, the United States and Spain, concluding that forests that had been thinned, logged or previously burned faced a higher risk of high-severity fires. They found that logging and hazard reduction burns -- a common practice across Australia outside of fire seas

In a new study published in the journal Science, the researchers created artificial stem cell embryo models that accurately mimic all the essential features and components of this developmental stage, including the placenta, yolk sac, chorionic sac, and assorted external tissues essential for facilitating dynamic and healthy growth. Due to their genuine complexity, the human embryo models created by the WIS team could offer an unprecedented opportunity to gain fresh insights into the beginnings of embryos, acco
