An answer to the clean water crisis?

Researchers from the University of South Australia (UniSA) are currently developing and refining a low-cost technique that can derive freshwater from seawater, brackish water or contaminated water – powered by sunlight.
Freshwater scarcity is one of the most serious global challenges in the face of a growing population, changing climate and pollution. Currently, 1.42 billion people live in areas of high or extremely high water vulnerability, and so in recent years, research has been focused on developing new materials and technologies to turn seawater or polluted water into safe, drinkable water.
Targeting Bowel Cancer with Nanotechnology

Bowel cancer survival rates could be improved if chemotherapy drugs were delivered via tiny nanoparticles to the diseased organs rather than oral treatment. That’s the conclusion of Indian and Australian scientists who have undertaken a study using nanoparticles to target bowel cancer, the third most common cancer in the world and the second most deadliest.
The researchers have shown in animal experiments that nanoparticles containing the chemotherapy drug Capecitabine (CAP) attach themselves directly to the diseased cells, bypassing healthy cells and therefore reducing toxic side effects as well as the size and number of tumors.
Modern Drones Could Mimic 300-Million-Year-Old Dragonflies

Scientists from the University of South Australia drew inspiration from a 300-million-year-old flying machine the dragonfly to illustrate why future flapping-wing drones will perhaps look like the insect in wings, shape, and gearing.

A group of PhD students guided by Javaan Chahl, Professor of Sensor Systems at the University of South Australia (UniSA), used part of the 2020 COVID-19 lockdown to build and test important parts of a dragonfly-inspired drone that might equal the amazing skills of the insect in cruising, hovering, and aerobatics.
