What were the biggest national and international science stories of 2015?
conSCIENCE
The Science Next Collaborative is helping early- and mid-career researchers to make the leap from research to commercialisation.
NEUROPSY
The study of aphantasia offers a window into our ability to visualise.
QUANDARY
Talk of IVF as a solution for declining birth rates is a sign that governments are clutching at straws.
THE NAKED SKEPTIC
Harry Messel was the inspiration for a talk Peter Bowditch gave at the 2015 Young Scientist Awards organised by the Science Teachers’ Association of NSW.
THE FIT
To sit or stand has become an uncomfortable question for health researchers.
THE FOSSIL FILE
Dangerously lows levels of trace elements might be implicated in three mass extinctions.
EXPERT OPINION
The Bureau of Meteorology has released its Annual Climate Statement for 2015.
The Federal government has shortlisted six sites for a permanent National Radioactive Waste Management Facility. The site will contain Australia’s low-level radoactive waste, with the capacity to store some intermediate-level waste.
OUT OF THIS WORLD
A milestone in predicting solar flares, and the discovery of a global ocean on Saturn’s moon Enceladus.
THE BITTER PILL
Alternative health practitioners are quick to offer a variety of untested therapies. Nanotechnology is yet another in the list.
LOWE TECH
The Turnbull government’s support for the coal industry relies on twisted logic.
ECO LOGIC
Australia has a rich diversity of freshwater crayfish, but many of our species are at risk.
SIMON SAYS
Whether new technologies are applied for good or ill, they encounter evolutionary pressure to fit in to the environments they inhabit.
UP CLOSE PODCAST
Behavioral neuroscientist Prof Andrew Lawrence discusses addictive and compulsive behaviors around drug and alcohol use, the power of psychological dependence, and how the brains of addicts differ from those of the rest of us.
Two young science researchers discuss their investigations of microbes that threaten, respectively, human health and our food supply. We chat with Claire Gorrie about aspects of the drug-resistant bacterium Klebsiella pneumoniae, and how it's implicated in serious infections. And Rebecca Vandegeer tells us how the Barley Yellow Dwarf virus strips our wheat crops of their defences, posing a threat to food security.
DIRECTIONS
Subsidies are required to provide industry-wide access to additive manufacturing technologies.
