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.

Not many physicists have lent their names to a mountain as did Parsons to a “huge, sheer-sided” peak at the northern end of the David Range in Australian Antarctic Territory. This followed the first exploration of the David, Casey and Masson ranges in January 1956 by an Australian National Antarctic Research Expedition party of five led from Mawson by Antarctic explorer John Béchervaise over heavily crevassed ice. Béchervaise and Neville "Nod" Parsons were subsequently awarded Imperial Polar Medals for their work.

Nicknamed “the rock stars of the ocean” because they live fast and die young, cuttlefish have a life span of just 12-18 months, so impressive displays are necessary to attract a mate. Photo: Carl Charter

Flowing arms, skins that change colour in an instant, dance battles and petite males disguised as females to trick their rivals – the courting behaviour of the alien-like Giant Australian Cuttlefish would look more at home in a Star Wars night club.

Each year more than 100,000 of the bizarre creatures gather in South Australia’s Upper Spencer Gulf Marine Park in what is the only known mass aggregation of its kind in the world.

Nicknamed “the rock stars of the ocean” because they live fast and die young, cuttlefish have a life span of just 12-18 months. This makes each May to August breeding season critical because the number of surviving eggs one year directly impacts the number of adult cuttlefish that return the next year to breed.

Personal Deterrents Can Reduce the Risk of Shark Bites

A study tests how effectively commercial shark deterrents reduce the risk of shark bites.

Many things might explain why the number of shark bites appear to be increasing. However, the infrequent occurrence of such events makes it nearly impossible to determine why. Recently, an atypically high rate of shark bites occurred in Western Australia in 2010-2011 and on the north coast of New South Wales in 2015-2016. These highly publicised events — often sensationalised in both traditional and social media — have pressured governments to implement new measures to reduce the risk of shark bites.

Weird science was out in force in 2017 - someone named a planet Bernard, sheep were trained to recognise Baaarack Obaaama, octopuses marched out of the sea, and re-inflated dolphin dangly bits revealed some sea sex secrets, among many other peculiar science yarns.

A Scientist’s Defense of Free Will

By Mahir S. Ozdemir

Why scientists should not jump to the unwarranted conclusion that free will is just an illusion.

Our commonsensical view holds that everything we do in life is a choice and we are totally free to choose between the options which we think are available to us. Many scientists, however, see a fundamental problem with the conventional wisdom about free will and claim that it is nothing more than an illusion.
