The annual highlights research published in 2019 that has generated significant international online attention and discussion – from patents and public policy documents to mainstream media, blogs, Wikipedia, and social media platforms.
The ‘insect apocalypse’
Dr , an honorary associate with the in the , penned an article that, for the first time, revealed a catastrophic threat exists to 40 percent of insect species over the next 100 years, with butterflies, moths, dragonflies, bees, ants and dung beetles most at risk.
Dr Francisco and his colleagues found the main drivers for species loss are intensive agriculture, pollution and climate change.
“Because insects constitute the world’s most abundant animal group and provide critical services within ecosystems, such an event cannot be ignored and should prompt decisive action to avert a catastrophic collapse of nature’s ecosystems,” the report, , said.
The research, which ranked as the 13th most influential of the year, caused a worldwide media frenzy, with more than 500 news stories and blogs around the world, including , which broke the story, , and , as well as 5000 tweets and was even .
Speaking to ABC television in Australia, Dr Sanchez-Bayo said: “We are not alarmists, we are realists. We are experiencing the sixth mass extinction on Earth. If we destroy the basis of the ecosystem, which are the insects, then we destroy all the other animals that rely on them for a food source.
“It will collapse altogether and that’s why we think it’s not dramatic, it’s a reality.”
The birthplace of modern humans
Professor , from the and Garvan Institute of Medical Research, pinpointing the birthplace of modern humans in southern Africa, where they thrived for 70,000 years.
Professor Hayes and her team studied samples of mitochondrial DNA to shine a light on early human explorations, which they believe were triggered by a change in climate and initiated the development of humans’ genetic, ethnic and cultural diversity.
The findings provide a window into the first 100,000 years of modern humans’ history and generated much debate in the media as well as on social media, with more than 260 news stories and 800 Tweets, placing the research as the world’s 67th most influential paper of 2019.
University of Sydney Vice-Chancellor and Principal Dr Michael Spence congratulated Professor Hayes and her team on the discovery.
“This is an outstanding result for Australian research, providing fascinating insights into our ancestry,” Dr Spence said.
“This goes to show what can be achieved when people collaborate globally for a shared purpose; it’s also an exemplary example of academic endeavour – a leading genetic expert recognising the potential of the genetic clues in our cells to answer big questions in anthropology and human origin.”
