A round-up of the latest science and news from Australasia.

Gene Editing of Stem Cells Hastened

A new technique has demonstrated how genetically repaired stem cells can be derived from patient skin cells in as little as 2 weeks, compared with conventional multi-step approaches that take more than 3 months.

Light Exposure Linked to Weight Gain in Children

Pre-schoolers exposed to more light earlier in the day tend to weigh more, according to research presented to the Sleep Downunder Conference in Melbourne.

Early childhood researchers at Queensland University of Technology studied 48 children aged 3–5 years over a 2-week period, measuring each child’s sleep, activity and light exposure along with their height and weight.

Scientists Don’t Turn a Blind Eye to Bias

Scientific journals should insist on more robust experimental processes, according to biologists who reviewed nearly 900,000 experiments.

The team from The Australian National University found that non-blind experiments – where scientists knew which samples they were recording – averaged a 27% stronger result than blind trials. However, their review suggests that less than one in four experiments used blind data recording.

A One-Shot Flu Jab for Life

A research team led by the University of Melbourne has determined how flu-killing CD8+ T cells memorise distinct strains of influenza, opening the way for the development of a one-shot flu jab for life.

The research began during the first outbreak of the avian-derived H7N9 virus in China in 2013, which saw 99% of people infected hospitalised and a 30% mortality rate. Patient zero was an elderly man who caught the virus from a chicken his wife asked him to buy at the local live bird market.

Sting in the Tail for Rare Species Conservation

The reintroduction of six severely threatened species – including bilbies and bettongs – back into their natural habitat at Scotia Sanctuary in western NSW has seen a decline in scorpions and increase in spiders. Scorpions had flourished without predation by the mammals.

Venoms Don’t Lose Their Bite

Our Galaxy’s Black Hole Is Not As Deadly As First Thought

A study published in Monthly Notices of the Royal Astronomical Society has indicated that, contrary to past theories, supermassive black holes are not responsible for starving their host galaxies to death.

Led by Macquarie University PhD candidate Michael Cowley, the researchers concluded that it’s unlikely that the Milky Way’s supermassive black hole is starving our galaxy of its precious star-forming fuel supply. “This work has the potential to rewrite our understanding of how the Milky Way and similar galaxies form and evolve over cosmic time,” Cowley said.
