Brain Circuits that Control Drinking
Cutting-edge genetic technology has revealed how the “love hormone” oxytocin protects us from drinking too much, and could lead to a better understanding of the brain circuitry underlying mental illnesses.

In Living Colour
Colour perception is more advanced in goldfish than humans, yet researchers have tended to focus on vision in animals similar to us. Justin Marshall says this is “fundamentally stupid” and is setting his sights on a marine creature with 12...

Crystals So Flexible They Can Be Tied in a Knot
The ordered structure of most crystals makes them brittle and inflexible, but the discovery of crystals with elastic properties opens a range of new uses in emerging technologies.

Neurogenesis in the Emotion-Processing Centre of the Brain
The generation of neurons during adulthood can affect our behaviour and alter our mood, so the discovery that this occurs in the amygdala could lead to new strategies for the treatment of anxiety-related disorders.

The death in Hobart on 30 December 2017 of 91-year-old Antarctic physicist and expeditioner Dr Neville (Nod) Parsons marks the end of an era of Australian Antarctic research and exploration.
UP FRONT
A study reporting a weak association between two genes and homosexuality could have powerful consequences.
NEUROPSY
Illusory pattern perception is associated with a belief in conspiracy theories.
conSCIENCE
Kangaroo harvesting is not a commercial option for landholders, resulting in greater animal welfare issues for the kangaroos that are culled on private land.
LOWE TECH
Fifteen thousand scientists have issued a warning to humanity that “many current life forms could be annihilated or committed to extinction by the end of this century”.
ECO LOGIC
Robust science is telling us orangutan populations are in serious decline but the Indonesian government is disputing the finding.
QUANDARY
Claims of the successful transplant of a human head may have been met by derision but they also reveal bioethical blindspots among ambitious surgeons.
THE NAKED SKEPTIC
Knowing about science is more important than doing science because it helps you separate sense from nonsense.
OUT OF THIS WORLD
Astronomers find more evidence for how life began in Earth, and send a greeting to a red dwarf with two habitable planets.
THE BITTER PILL
The internet allows greater broadcasting of false information about cancer cures, which means that women are treating their breast cancer with alternative therapies known to be the direct cause of preventable deaths.
DIRECTIONS
The Gold Rush left behind thousands of mines that remain toxic to the environment. The mining sector needs to develop a national abandoned mine initiative to regain public trust.
EXPERT OPINION
Researchers have been considering using gene drives to rid New Zealand of invasive pests, but have they adequately estimated the issues and addressed indigenous rights?

Why write books? For some, it's a need — to find out what we think, and get the record down for all of history to see. And in science, there's the need to update what's known, something Emeritus Professor John Bradshaw has done.
