Indian scientists have found an ingenious way to cut smog

Burning Crops India
Every year, a choking smog descends on northwest India as the region's farmers burn their fields following the rice harvest - a phenomenon that has helped make New Delhi one of the world's most polluted cities. Now, scientists have come up with a method that would allow farmers to sow their winter crop, usually wheat, without burning off the stubble left behind after the rice harvest. Researchers tested 10 alternatives to burning, finding the big...

This is how The Ocean Cleanup's mission to clear the Great Pacific Garbage Patch is going

Beach Rubish
The world produces 300 million tonnes of plastic a year. There are 5 trillion pieces of plastic in the ocean, and 90% of seabirds have swallowed plastic. The stats about ocean plastic are so stark and the problem so seemingly insurmountable, you could be forgiven for wondering what on Earth we're going to do about it. But Dutch inventor Boyan Slat thinks he has a solution: a giant floating barrier, or boom, that uses natural forces to passively s...

Seoul is putting solar panels on all public buildings and 1 million homes

Solar Panels
Look up as you walk the streets of South Korea's capital and you'll see a renewable-energy revolution taking place. By 2022, every public building and 1 million homes in the city are set to be powered by solar. The Solar City Seoul project is part of a programme to wean Asia's fourth-largest economy off its dependence on coal, gas and nuclear for power generation. The country aims to generate 35% of its electricity from renewables by 2040. The Wo...

India is using hundreds of drones to map the country in incredible detail

How do you map one of the largest countries in the world? One drone at a time, perhaps. That's exactly what the Indian government is doing, with the Survey of India (SoI) using a fleet of drones to map the country in incredible detail. One of the first areas being surveyed is the Ganges river basin, which is being mapped with an accuracy of 10 cm, according to Professor Ashutosh Sharma of India's Department of Science & Technology. "The basis...

Blue Acceleration: our dash for ocean resources mirrors what we’ve already done to the land

Oil Rig
Humans are leaving a heavy footprint on the Earth, but when did we become the main driver of change in the planet's ecosystems? Many scientists point to the 1950s, when all kinds of socioeconomic trends began accelerating. Since then, the world population has tripled. Fertiliser and water use expanded as more food was grown than ever before. The construction of motorways sped up to accommodate rising car ownership while international flights took...

‘Death by a thousand cuts’: women of colour in science face a subtly hostile work environment

Women in science lab
It's hard for women to succeed in science. Our research shows it's even harder for women of colour. We interviewed women of colour working in scientific and technical organisations across Australia about their experiences. As well as direct discrimination, they face a barrage of brief, everyday racial slights and indignities that one described as "death by a thousand cuts". In addition, we found women of colour often hesitate to tackle these affr...

Big Pharma has failed: the antibiotic pipeline needs to be taken under public ownership

Antibiotics are among the most important medicines known to humankind, but we are running out of this crucial resource. Decisive action is needed if we are to retain access to them. This includes rethinking our reliance on private companies and establishing public ownership of crucial parts of the antibiotic pipeline. Since the 1930s, antibiotics have transformed the way we treat diseases, ranging from syphilis to typhoid. They have enabled incre...

A model of destination loyalty: integrating destination image and sustainable tourism

According to the United Nations, 68% of the world population is projected to live in the cities by 2050. China, India, and Nigeria collectively are projected to constitute 35% of total growth in urban population from 2018 to 2050, with China alone adding 255 million urban dwellers. Shanghai happens to be the most populated city in China as well as the world's third most populated city. Therefore, it is crucial to ensure the sustainability of Shan...

Electric car sales tripled last year in Australia. Here’s what we can do to keep them growing

A total of 6718 electric vehicles were sold in Australia in 2019. That's three times as many as in 2018, but it's still small beer. More than a million fossil-fueled light vehicles (including SUVs and utes) were sold in the same period. The sales figures were published in the wake of UK Prime Minister Boris Johnson's announcement that sales of petrol or diesel cars will be banned in the UK by 2035. The UK's isn't the only right-of-centre governme...

Microplastic pollution is everywhere, but scientists are still learning how it harms wildlife

Plastic pollution is a growing global concern. Large pieces of plastic have been found almost everywhere on Earth, from the most visited beaches to remote, uninhabited islands. Because wildlife are regularly exposed to plastic pollution, we often ask what effects plastics have on the animals. Over time, macroplastics (plastic debris larger than five millimetres in size) break up into tiny particles called microplastics (smaller than five millimet...
