Today, 2.2 billion people lack access to safely managed drinking water. And waterborne diseases claim 830,000 lives a year, most of them children. Nearly half the globe already experiences water scarcity at least one month per year. And by 2050, according to the UN, this number could reach up to 5.7 billion people. Yet climate change, our rapidly ballooning population, and consistently poor resource management aren’t helping matters. The annual…

Researchers at UniSA have developed a cost-effective technique that could deliver safe drinking water to millions of vulnerable people using cheap, sustainable materials and sunlight.Less than 3 per cent of the world's water is fresh, and due to the pressures of climate change, pollution, and shifting population patterns, in many areas this already scarce resource is becoming scarcer.Currently, 1.42 billion people -- including 450 million children -- live in areas…

By Wania C.R.B. Paranaiba and Adriano C. Paranaiba 1. Cannabis and Cannabidiol Cultivated almost globally due to its easy adaptation, Cannabis sativa plants hold over one hundred identified compounds called cannabinoids. However, it is not the only species of the Cannabis genus. There are also Cannabis indica, a species with a low concentration of the psychoactive substance THC (tetrahydrocannabinol), and Cannabis ruderalis, with no psychoactive properties.1Phytocannabinoid compounds are natural. They…

Carbon capture is viewed by many as a last resort. But in the race to tackle the climate crisis, intelligently taking advantage of natural processes will be key We’re transitioning to renewables; we are using the energy we generate with extraordinary efficiency; our industries are innovating with clean, green methods; we’re recycling, reusing and reclaiming. Our greenhouse gas emissions are slowing. But perhaps it’s not enough. There is another final…

The combination of climate change, deforestation, pollution, overfishing, and more have produced a biodiversity crisis. On a bad day, 200 species go extinct. If we project current rates, by century’s end, 50% of all large mammals and marine life will disappear. And by 2050, 90% of coral reefs—which are home to 25% of the world’s biodiversity—could be gone. But all is not lost yet, as some of today's best minds…

If limbs, kidneys and lungs are instruments constituting the body’s orchestra, the brain is its conductor, the difference between cacophony and symphony. But what if technology could quietly, almost surreptitiously, influence the way our brain functions, as The Matrix predicted two decades ago? Today’s Sunday Magazine dives into the latest cutting-edge research and inventions in neurotechnology, exploring how they could make us smarter and improve our quality of life ……
