Apex marine predators choose who they hang with, researchers reveal.
White sharks form
communities, researchers have revealed.
Although normally
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.
Now, however,
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.
Analysis of reef damage in the Indo-Pacific during the 2016 El Nino reveals that several different stressors influence bleaching.
Scientists in the Indian and Pacific Oceans used the El Nino of 2016 – the warmest year on record – to evaluate the role of excess heat as the leading driver of coral bleaching and discovered the picture was more nuanced than existing models showed.
The findings were, in a word, complicated, according to marine researchers led by the US based Wildlife Conservation Society (WCS). The international cohort included scientists from Macquarie University in NSW, the University of Queensland, University of WA and two western Australian state government departments.
Macquarie astronomers find a well of serenity in deep space.
A massive galaxy four billion light-years from Earth is surrounded by a halo of tranquil gas.
The finding, which reveals a galactic halo much less dense and less magnetised than expected, was made by a team of astronomers that included two researchers from Macquarie University.
The shape of immune cells plays key role in recognising invaders.
The way immune cells pick friends from foes can be described by a classic maths puzzle known as the “narrow escape problem”.
That’s a key finding arising from an international
collaboration between biologists, immunologists and mathematicians, published
in the journal Proceedings of the National Academy of Sciences.
The narrow escape problem is a framework often applied in cellular
biology. It posits randomly moving particles trapped in a space with only a
tiny exit, and calculates the average time required for each one to escape.
Members of at least one species choose mates and egg sites based on where they were born, research reveals
Birthplace exerts
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.
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.
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
Prizes.
The awards were
held in Sydney on Wednesday, August 28.
Scientists urge priority action on hundreds of surviving reefs.
The majority of 2500 reefs surveyed in a major international exercise retain the coral species that give them their distinctive structure.
More than 80 marine scientists, including several from Australia, contributed to the study, which is published in the journal, Nature Ecology and Evolution.
Australia-UK
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.
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
lives.
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.
Recent
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.

This is one of the best science communication courses I have ever encountered. It teaches all research to think out of box and really simplify their research in lay man's language. I will highly recommend this to anyone looking to learn more about science communication.
