Data gathered by NASA’s now defunct Kepler telescope provides a solution to an astronomical mystery.
Star-quakes recorded by NASA’s Kepler space telescope have
helped answer a long-standing question about the age of the “thick disc” of the
In a paper published in the
journal Monthly Notices of the Royal Astronomical Society,
a team of 38 scientists led by researchers from Australia’s ARC Centre of
Excellence for All Sky Astrophysics in Three Dimensions (ASTRO-3D) use data
from the now-defunct probe to calculate that the disc is about 10 billion years
Academic journal rules are
penalising citizen scientists and indigenous knowledge, say US and Australian
Citizen scientists should be
included as authors on journal papers, researchers say.
In a paper published in the journal Trends in Ecology and Evolution, a team led by biologist Dr Georgia Ward-Fear from Macquarie University in Australia and Dr Greg Pauly from the Natural History Museum of Los Angeles argues that newfound respect for indigenous knowledge and changes in technology mean that non-professionals are taking greater roles in science work.
Researchers find familiar species pave the way for coral regrowth
contrast to most other species, reef-dwelling parrotfish populations boom in
the wake of severe coral bleaching.
surprise finding came when researchers led by Perth-based Dr Brett Taylor of
the Australian Institute of Marine Science (AIMS) looked at fish populations in
severely bleached areas of two reefs – the Great Barrier Reef in the western
Pacific and the Chagos Archipelago in the Indian Ocean.
Andreas Strasser and David Vaux win $50,000 CSL Florey Medal for Lifetime Achievement for identifying cell death triggers and using them to fight cancer.
Past CSL Florey Medallists include Graeme Clark, Ian Frazer, and Nobel Laureates Barry Marshall and Robin Warren.
In the late 1980s to early 1990s, two Melbourne scientists, Andreas Strasser and David Vaux, discovered the molecular processes that cause billions of cells in each of us to die every day. They showed that some cancer’s cells can evade this process of programmed cell death and ‘fail to die’. So far, their findings have led to powerful new treatments for leukaemia and opened a new field of research which generates 25,000 papers every year. And, they say, there is still much to learn.
Sky survey provides clues to how they change over time.
The direction in which a galaxy spins depends on its mass, researchers have found.
A team of astrophysicists analysed 1418 galaxies and found that small ones are likely to spin on a different axis to large ones. The rotation was measured in relation to each galaxy’s closest “cosmic filament” – the largest structures in the universe.
Filaments are massive thread-like formations, comprising huge amounts of matter – including galaxies, gas and, modelling implies, dark matter. They can be 500 million light years long but just 20 million light years wide. At their largest scale, the filaments divide the universe into a vast gravitationally linked lattice interspersed with enormous dark matter voids.

A novel citizen science project in New Caledonia finds an ‘astonishing’ number of venomous reptiles in a popular swimming spot.
A group of snorkelling
grandmothers is helping scientists better understand marine ecology by
photographing venomous sea snakes in waters off the city of Noumea, New Caledonia.
Two years ago the seven women, all in their 60s and 70s, who call
themselves “the fantastic grandmothers”, offered to help scientists Dr Claire
Goiran from the University of New Caledonia and Professor Rick Shine from
Australia’s Macquarie University in their quest to document the sea snake
population in a popular swimming spot known as Baie des citrons.
Apex marine predators choose who they hang with, researchers reveal.
White sharks form
communities, researchers have revealed.
solitary predators, white sharks (Carcharodon
carcharias) gather in large numbers at certain times of year in
order to feast on baby seals.
These groupings, scientists had assumed, were essentially random – the result of individual sharks all happening to turn up in the same area, attracted by abundant food.
a group of researchers including behavioural ecologist Stephan Leu from
Macquarie University in New South Wales, Australia, have used photo-identification
and network analysis to show that many of the apex predators hang out in groups
which persist for years.
