Researchers have successfully initiated an artificial endosymbiotic relationship by implanting the bacterium Mycetohabitans rhizoxinica into the fungus Rhizopus microsporus, which is a significant step in understanding the evolution of complex life forms. This experiment successfully recreated a natural symbiosis, in which the bacteria not only thrived but also became incorporated into the cellular structure of the fungi. The fact that the bacteria were present in the next generation of fungi indicates this relationship can be passed down, shedding light on how organelles like mitochondria and chloroplasts may have originally evolved.
Despite the massive H5N1 avian influenza outbreak affecting cattle in the US, Australia remains free from this highly pathogenic strain. Scientists theorize that Australia's geographical isolation, along with specific migratory behaviors of its bird species, may attribute to the absence of the virus in Oceania. However, virologist Michelle Wille cautions against complacency, noting that it's not a matter of if the virus will eventually arrive in Australia, but rather when it will make its presence felt.
