Mapping species and coral bleaching by drone

Advanced, miniature cameras on drones are capturing details of landscapes that have previously been invisible. QUT researchers are using them to fly low over reefs, capturing almost 100 times the colours captured by standard cameras.

“High-altitude surveys of reefs may lack the resolution necessary to identify individual corals or bleaching effects,” says Associate Professor Felipe Gonzalez, who is leading a team of researchers and unmanned aerial systems (UAS) engineers from QUT in a partnership project between QUT and the Australian Institute for Marine Science (AIMS).

Earthquake-proofing ports

Researchers from The University of Melbourne are learning how to modify existing Indonesian and Australian ports so earthquakes don’t do such devastating damage to sea trade.

“What we currently have is a recipe for disaster. Some of the port infrastructure is over 100 years old and wasn’t designed to cope with the loads they are currently bearing, let alone an earthquake,” says Dr Massoud Sofi.

Gravitational waves—looking further

The brainpower of 18 institutions and more than $30 million are expanding the net to detect gravitational waves—disturbances in the fabric of spacetime—and cement Australia’s role in the emerging field.

Robo reef protector

A fleet of autonomous robots is being developed by Queensland scientists to kill crown-of-thorns starfish (COTS), and monitor the health of the Great Barrier Reef.

Dr Matthew Dunbabin and Dr Feras Dayoub of QUT are working with the Great Barrier Reef Foundation to create the RangerBot, following successful field trials of QUT’s COTSBot in 2016.

Modern humans were in Southeast Asia 20,000 years earlier than previously thought

Dating of ancient human teeth discovered in a Sumatran cave site suggests modern humans were in Southeast Asia 20,000 years earlier than previously thought.

The international research, led by Dr Kira Westaway from Macquarie University and published in Nature, has pushed back the timing of when humans first left Africa, their arrival in Southeast Asia, and the first time they lived in rainforests.

Does coral help create rain?

Researchers have found that coral reefs may play a key role in cloud formation. Now they’re working to make climate modelling more accurate.

Australian and international scientists, led by QUT’s Professor Zoran Ristovski, spent a month in late 2016 collecting data on airborne particles emitted from the Great Barrier Reef, which they are now analysing.

Technology to save the reefs—Queensland University of Technology

Mapping reefs with drones; robots destroying crown-of-thorns starfish; coral as a rain-maker; and more—researchers at the Queensland University of Technology (QUT) are investigating new technologies to protect Australia’s reefs.

Growing food and stopping floods with rain gardens

Small urban ‘rain gardens’ are popping up all around Australia and Indonesia to keep waterways free from pollutants, stop flooding and erosion, and to grow food.

Although they may look similar to a normal garden, beneath the surface rain gardens are a sandwich of layers of sand, gravel, roots and microbes through which polluted water passes and clean water exits, which can then be used for irrigation or washing.

Honey for your wounds?

The benefits of using medical-grade honey to treat and prevent infection in wounds has been confirmed by Sydney researchers.

Dr Nural Cokcetin tested more than 600 Australian honey samples and documented the antibacterial activity, which strongly corresponds to the levels of methylglyoxal (MGO), one of honey’s most active ingredients.
