Australasian Science: Australia's authority on science since 1938
Australasian Science Magazine Issue Sep/Oct 2018
The discovery of a new form of photosynthesis extends the limits where life can survive on Earth, and might provide a first step to terraforming Mars. |
There is a common misconception that space is a pristine global commons that sits above terrestrial geopolitical rivalries. Nothing could be further from the emerging reality.

Our modern 24/7 appetite is disrupting natural gastric signalling oscillations to the brain. Restricting meal times could help weight loss and maintenance, particularly among shiftworkers.
|
A new treatment for chronic constipation involves sticking lights “where the sun don’t shine”. |
Attempts to catch the biggest fish may have unwittingly caused the fishing industry to crash in many parts of the world. To make things more worrying, new research indicates that climate change will reduce the capacity of fish to reproduce.

More than 100,000 citizen scientists have taken part in the world’s first global quantum physics experiment to test Einstein’s concept of “local realism”. |
A scientific voyage has revealed startlingly warm waters around a glacier in East Antarctica that could raise global sea levels by 4 metres. |
Electric vehicles are expected to take over our roads in the coming decade, but can our electricity infrastructure cope with the additional demands they will place on it? |

Arguments that electric vehicles are no “greener” than the electricity they use fail to acknowledge the increasing role of renewables in the energy grid. |
Carbon may be acidifying the oceans, but the species it’s supposed to harm are fighting back. |
conSCIENCE:
Your Nitrogen Footprint Has Far-Reaching Consequences
Australia’s reliance on coal and taste for beef is contributing to nitrogen pollution as far away from our population centres as the Great Barrier Reef. |

The Bitter Pill:
The MINDD Foundation is Built on Shaky Ground
A forum held at The University of NSW, but not endorsed by it, has highlighted the spurious credibility that university settings give to groups making unsubstantiated health claims.
|
The SAGE program aims to engender balance in STEM professions. |
Oceans are inherently three-dimensional spaces, so effective and efficient conservation planning in oceans should take this third dimension – depth – into account. |
Expert Opinion:
Mozzies Knocked out with Gene Drive
Researchers say they've successfully used a CRISPR-based gene drive to cause the collapse of a population of caged malaria-carrying mosquitoes by targeting a gene that determines whether an individual mosquito develops as a male or a female. |
Our present epoch has been called the Anthropocene because of the dominance of human activity, but perhaps it should be called the Plasticine. |
Naked Skeptic:
A Brief History of Some Science
Science has brought public health a long way since the voyages that led to Australia’s discovery and settlement were ravaged by disease. Why, then, do some people want to turn back? |
A reduced sense of personal agency persuades Ouija board users to believe in ghostly messages.

A probe will travel through the Sun’s atmosphere, and astronomers have found the fastest-growing black hole known in the universe. |
Just because the non-medical use of cognitive stimulants isn’t common, it doesn’t mean it isn’t a problem. |
Up Front:
A Military Motive for the Space Agency
National security, not economic opportunity, may have motivated the government’s new interest in a sovereign space capability. |
