Story Opportunities from Australasian Science, November 2009
For Immediate Release
Research reveals that we remember more and make better decisions when
we're in a sad mood.
A Question of Gender
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.
Down Syndrome Disappearing
Cheap prenatal diagnostic tests are on the way, but is the decline in
Down syndrome births the tip of the iceberg?
The “Impossible” Eye
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.
The Rise of Seahorses
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.
Facial Birth Defects Unmasked
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
Australian radioastronomers have boosted their case for hosting the
Square Kilometre Array of antennas with a major geographic extension
strengthening the bid in key scientific aspects.
Was the Christmas Star Real?
Was the Star of Bethlehem purely a divine sign or an astronomical
event in its own right?
Galaxies in Collision
Our nearest large neighbouring galaxy, Andromeda, has been interacting
with the smaller Triangulum Galaxy, with a trail of stars between them
adding weight to theories of galaxy formation.
How a Moon Got its Stripes
An eruption of water vapour on one of Saturn’s moons has revealed
tectonic activity and a subsurface ocean.
The Science of Science Fiction
Science fiction has predicted many of the technologies that we take
for granted today.
The Vital Importance of Habitat
Destruction of an organism’s habitat is one, if not the major, cause
of species extinction in Australia. Protecting habitat is the key to
halting Australia’s declining biodiversity.
The Evaporation Paradox
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.
