Members of at least one species choose mates and egg sites based on where they were born, research reveals
a lifelong influence on butterflies as well as humans, new research reveals.
In a paper
published in the journal Proceedings of the Royal Society B: Biological
Sciences, Macquarie University ARC Future Fellow Associate Professor
Darrell Kemp reveals that the American passionfruit butterfly, Heliconius
charithonia, selects its mate and egg-laying site based on the species of
plant that hosted its own egg.
The NISEP program has helped almost 1000 Indigenous school children enter leadership roles.
The National Indigenous Science
Education Program (NISEP),
based at the Faculty of Science and Engineering at Sydney’s Macquarie
University, won the inaugural the Eureka Prize for STEM Inclusion at the 2019 Australian Museum Eureka
The awards were
held in Sydney on Wednesday, August 28.
Collaboration investigates the link between changing sea levels, global warming and the health of marine wetlands.
Carbon dioxide capture by coastal ecosystems operates in direct relation
to the speed of sea level rise.
That was the conclusion of extensive research conducted by a team of
scientists from Macquarie
University, University of Wollongong and ANSTO – work that has now won the
scientists the NSW
Environment, Energy and Science (DPIE) Eureka Prize for Environmental Research.
researchers identify ancient protein pumps that make bacteria tough to treat –
but could be key to new green polymers
The molecular machinery used by bacteria to
resist chemicals designed to kill them could also help produce precursors for a
new generation of nylon and other polymers, according to new research by
scientists from Australia and the UK.
“Resistance to artificial antiseptics
appears to be a lucky accident for the bacteria, and it could also be useful
for humans,” says Professor Ian Paulsen of Australia’s Macquarie University,
one of the leaders of the research group.
Early results from Australia-wide experiment suggest being outdoors can be a good way to trigger “aha” moments.
People are most likely to have a sudden bright idea when
out in the bush – or lying in bed.
That’s one of the early observations arising from The Aha!
Challenge, the month-long Australia-wide science experiment that kicked off
during National Science Week and runs until the end of August.
The experiment, which revolves around a series of online
brainteasers, aims to explore sudden bursts of clarity and insight, and their
role in problem-solving. In effect, it’s a nationwide quest to find the things
that make you go “aha!”…
Australian scientists develop cheap and rapid way to identify antibiotic-resistant golden staph (MRSA).
A combination of off-the-shelf quantum dot nanotechnology
and a smartphone camera soon could allow doctors to identify
antibiotic-resistant bacteria in just 40 minutes, potentially saving patient
Staphylococcus aureus (golden staph), is a common form of bacterium that causes serious and sometimes fatal conditions such as pneumonia and heart valve infections. Of particular concern is a strain that does not respond to methicillin, the antibiotic of first resort, and is known as methicillin-resistant S. aureus, or MRSA.
reports estimate that 700 000 deaths globally could be attributed to antimicrobial
resistance, such as methicillin-resistance. Rapid identification of MRSA is
essential for effective treatment, but current methods make it a challenging
process, even within well-equipped hospitals.
Chinese-Australian research finds climate change good news, and solves an evolutionary mystery
Baby turtles influence their gender by moving around inside
their eggs, research has revealed.
The idea that an embryo reptile can act in a way that
affects its chances of developing as male or female has long been thought
impossible, but findings by scientists from China and Australia have now provided
clear proof of the process.
The research, published in the journal Current Biology,
solves a long-standing evolutionary mystery – and offers hope that at least
some species thought especially vulnerable to effects of climate change will prove
more robust than thought.
Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.
A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.
In a paper published in the journal Monthly Notices of
the Royal Astronomical Society: Letters, researchers led by Dr Thomas
Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3
Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red
giant star, located in the halo of the Milky Way, on the other side of the
Galaxy about 35,000 light-years from Earth.
Macquarie University’s Professor Rob Harcourt urges Oceania-wide action to safeguard several species.
Sharks in Australian waters are well protected but
are at risk as soon as they leave them, a new international study reveals.
The study compiled by 150 scientists around the
world – including 26 with ties to Australia – has found thateven in the most remote parts of the world’s oceans migratory
sharks are in severe danger from commercial fishing fleets, new research
In a paper published in the journal Nature,
more than 150 scientists, including Professor Rob Harcourt from the Department
of Biological Sciences at Australia’s Macquarie University, report that the
sharks – which include iconic species such as the shortfin mako (Isurus oxyrinchus) and the great white (Carcharodon
congregate in food-rich areas that are also prime hunting grounds for
commercial longline fishing fleets.
