Ten per cent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a study published in Communications Biology tonight.

“We found that exposure to chemicals leaching from plastic pollution interfered with the growth, photosynthesis and oxygen production of Prochlorococcus, the ocean’s most abundant photosynthetic bacteria,” says lead author and Macquarie University researcher Dr Sasha Tetu.

“Now we’d like to explore if plastic pollution is having the same impact on these microbes in the ocean.”

As partners in the $245 million SmartSat CRC announced in Adelaide this morning.

Eighty-four research and industry partners are contributing $190 million investment in cash and in kind to the new Cooperative Research Centre for Smart Satellite Technologies and Analytics, and the Australian government is contributing a further $55 million. The CRC is led by the University of South Australia. 

“A new generation of low-cost smart satellite technology has the potential to enhance agriculture, mining, communication and national security,” says Associate Professor Sam Reisenfeld, who leads Macquarie University’s contribution to the CRC.

CORRECTION: In our science news bulletin sent out on 3 April 2019 we stated that ARC, CSIRO, and NCRIS received funding cuts in the 2019 Federal Budget. This is incorrect and neither CSIRO, nor the ARC received funding cuts. We based our statement on an analysis by the Australian Academy of Science. This has since been clarified. Here is the updated media release and here is a statement about the CSIRO funding.

Over $350,000 in science prizes are open for nomination right now including 18 Eureka Prizes, WA and SA scientists of the year, and the APEC Science Prize. The ABC is inviting 10 postdocs to media bootcamps. The Science Academy’s awards are open, as are the Tall Poppies for early career researchers. Details on these, and more below. If you need help with your awards strategy, and with finessing nominations, give us a call.

Planning space missions is traditionally a time-consuming and costly process. But the new Australian National Concurrent Design Facility (ANCDF), housed at UNSW’s Canberra campus, speeds things up so a mission can be planned in weeks rather than months.

Harnessing the expertise, design processes and software of the French Space Agency CNES (Centre National d’Etudes Spatiales), the UNSW team has created Australia’s first concurrent design facility.

The ANCDF allows engineers and scientists—both professionals and students—to design different parts of a mission in parallel rather than one after the other, which is the traditional approach. [continue reading…]

A new kind of wheat high in resistant starch can improve intestinal health

Bowel cancer is the world’s third most common cancer. A diet that includes more resistant starch, a kind of fibre that feeds good bacteria in the large intestine, can make it less common. Resistant starch helps improve gut health and reduces the risk of conditions such as diabetes, obesity, heart disease and cancer.

Since 2006, CSIRO scientists have been working in a joint venture with French company Limagrain Céréales Ingrédients and the Grains Research and Development Corporation to develop wheat with more resistant starch. [continue reading…]

Nature Materials paper Tuesday, 19 February 2019

An international team of researchers led out of Macquarie University has demonstrated a new approach for converting ordinary laser light into genuine quantum light.

Their approach uses nanometre-thick films made of gallium arsenide, which is a semiconductor material widely used in solar cells. They sandwich the thin films between two mirrors to manipulate the incoming photons.

The photons interact with electron-hole pairs in the semiconductor, forming new chimeric particles called polaritons that carry properties from both the photons and the electron-hole pairs. The polaritons decay after a few picoseconds, and the photons they release exhibit distinct quantum signatures.

The teams’ research was published overnight in the journal Nature Materials.

An Aussie eucalypt can ‘remember’ past exposure to extreme heat, which makes the tree and its offspring better able to cope with future heatwaves, according to new research from Macquarie University.

This finding could have important implications for restoring ecosystems and climate-proofing forestry, as the number of hot days and heatwaves increase due to climate change.

The first accurate 3D map of our galaxy reveals its true shape: warped and twisted.

Background information and further images below.

Astronomers from Macquarie University and the Chinese Academy of Sciences have used 1339 ‘standard’ stars to map the real shape of our home galaxy in a paper published in Nature Astronomy today.

They found the Milky Way’s disc of stars becomes increasingly ‘warped’ and twisted the further away the stars are from the galaxy’s centre.

Cane toads are picking up some shady habits, according to a new study co-authored by a Macquarie University researcher.

Toads in Western Australia have been spotted awake and active during the day in deeply shaded habitats, despite the species usually being nocturnal in Australia and other parts of the world.

However nearby cane toad populations at more exposed sites remained only active at night.

Males have to make less of an effort to mate with promiscuous female fruit flies, making the quality and quantity of their semen all the more important in the competition to fertilise the females’ eggs.

This also leads to male flies repeatedly mating with the same female, according to a paper published overnight in Nature Communications, by researchers from Macquarie University, the University of Oxford and the University of East Anglia, who looked into the eyes of thousands of fruit flies.

Firestorms are a nightmare for emergency services and anyone in their path. They occur when a bushfire meets a ‘perfect storm’ of environmental conditions and creates a thunderstorm.

Dr Rachel Badlan and Associate Professor Jason Sharples are part of a team of experts from UNSW Canberra and ACT Emergency Services that has found the shape of a fire is an important factor in whether it will turn into a firestorm.

Fires that form expansive areas of active flame, rather than spreading as a relatively thin fire-front, are more likely to produce higher smoke plumes and turn into firestorms, the researchers found.

This finding is being used to underpin further development of a predictive model for firestorms. The model was trialed in the 2015 and 2016 fire seasons by the ACT Emergency Services Agency and the NSW Rural Fire Service, and now forms part of the national dialogue around extreme bushfire development.

Rice (Oryza sativa) is the major food source for more than half the world’s population. Photo: Pille-Riin Priske/Unsplash CC

Researchers have identified over 5,700 new proteins in rice and are calling for a global effort to find the remaining missing proteins, in a new study co-authored by Macquarie University.

The international team of scientists from Australia, Iran and Japan say there’s an estimated 35,000 proteins encoded by the rice genome, and yet we still don’t have experimental evidence for 82 per cent of them.

This is important because rice is the major food source for more than half the world’s population, and in order for it to grow in warmer climates and with less water we will need to better understand rice at the molecular level. [continue reading…]

From Sydney to Cairns to Darwin to Perth, we want to hear about your sightings – a live fish, a saw on the wall of your local pub, or a photo from your family album.
