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.
“Unlike animals, which can bury deeper into the soil or flee to cooler locations, plants are stuck in one spot and so must be able to withstand extreme conditions in situ,” says Dr Rachael Gallagher, senior author of the paper published in the journal Functional Ecology.

Changing lives together: from water to astronomy to cancer, this collection showcases outstanding collaborations between French and Australian researchers.
Scientific collaboration between Australia and France stretches back to the early days of European settlement, when La Pérouse built an observatory at Botany Bay in 1788.

Cooking with a hydrogen-powered barbeque
The need to shift from fossil fuels to cleaner energy technologies is becoming more urgent, and Australia’s trading partners are demanding low-emission energy sources.
Electricity production from renewables can be variable, and any excess electricity must be stored for use on days with less wind or sun. Battery systems are used for storage, but they have limitations.
An alternative is to store energy in the form of hydrogen.

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.

Australian and French researchers are teaming up to use photonics—the quantum technology of light—to build better environmental sensors and high-speed data transmitters, and enable sharper MRI scans.

A perfect view of the Milky Way
On a series of calm, cool mornings in April 2017, 70 French scientists (from the French space science agency CNES, CNRS IRAP, and the Université Paul Sabatier de Toulouse) launched three enormous balloons into the sky above the heart of Australia.
CNES was using the Alice Springs Balloon Launching Centre (ASBLS) to send three precision scientific instruments up to altitudes of 30–40 kilometres to make observations that are impossible from the ground.

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

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 The quest for the missing proteins in rice
