A “scientist’s scientist” has won the 2009 Australasian Science Prize for research that overturns assumptions of the impacts of climate change on water availability.

Think Negative!
By Joseph Forgas
Can a bad mood make us think more clearly?

The “Impossible” Eye
By Julian Cribb
The complexity of the eye has long been used as an argument to rebuff Darwin’s theory of natural selection, but evidence from primitive fish has revealed how the eye evolved from simple light-sensitive cells over a 30-million-year period.

A Question of Gender
By Louisa Ludbrook
Sex determination is a biological “battle of the sexes” that scientists have long believed is turned by the presence of a gene that triggers the development of male gonads. The role of an anti-male gene sheds new light.

The Rise of Seahorses
By Peter Teske and Luciano Beheregaray
Genetic data indicate that tectonic changes in Australasia and the associated formation of vast seagrass meadows may have driven the evolution of upright posture in seahorses.

The Science of Science Fiction
By Allan Kreuiter
Science fiction has predicted many of the technologies that we take for granted today.

Facial Birth Defects Unmasked
By Paul Trainor
A better understanding of the biological basis of congenital head and facial birth defects is leading researchers closer to developing preventative measures that can be applied in the womb.

 “Seeing” 20¢ at 3.7 Million Paces
By Peter Pockley
Australian radioastronomers have boosted their case for hosting the Square Kilometre Array of antennas with a major geographic extension and strengthening the bid in key scientific aspects.

Was the Christmas Star Real?
By Dave Reneke
Was the Star of Bethlehem purely a divine sign or an astronomical event in its own right?
