Creating Community Through the Act of Gardening

“Through one simple, little act, we can cultivate a world that is more diverse, unified, and collaborative, and less divided and lonely – ultimately, a world more joyous and sustainable than this one through one simple act: gardening,” begins a riveting TEDTalk by Jasun “Plaedo” Wellman, a community organizer, educator, gardener, and artist. Gardening, he said, offers a practical remedy to many of society’s increasingly common ills – disconnection, depression, […]

How Much Can Plants Hear?

Plants may possess more complex senses than previously thought, according to a new study led by the University of Western Australia that has revealed that plants have the ability to both detect and respond to sound. Talking to plants has always been fairly common practice among many aboriginal tribes – and to this day, the most devoted gardeners will claim that playing classical music or providing words of positive reinforcement […]

Continued Climate Change May Disrupt Ocean Currents

Climate change is giving us more to worry about than just rising seas, scientists claim. Greenland’s glaciers are melting fast, pouring ice into the Arctic Ocean – and according to a new study, this influx of freshwater from the melting ice could lead to a disruption of a major ocean current system. The consequence of this disruption could be devastating, drying out the narrow section of land from Mauritania to […]

City Greening Needs to be Done Properly to Mitigate Harmful Impacts of Global Warming

Covered in heat-trapping asphalt and concrete, cities can become urban heat islands that can stay hot even into the late-night hours. According to some studies, the heat-stress index for many European cities will double by 2050, when compared with adjacent rural areas. By 2100, some cities may even see a temperature increase of 8 degrees Celsius. While adding more trees and creating larger areas of shade seems like a perfect […]

Artificial Photosynthesis: Liquid Fuel Created from Sunlight by “Bionic Leaf”

Researchers at Harvard have developed a system of artificial photosynthesis – creating liquid fuel from sunlight, carbon dioxide, and water. Described in a new paper published in Science, the process could be a big step in reducing our dependence on fossil fuels. Daniel Nocera, a professor of energy science at Harvard, and his colleague, Pamela Silver, have achieved the process at an efficiency of 10 percent using pure carbon dioxide […]

How Creative Constraints Drive Innovation and Discovery

“Imagine you’re asked to invent something new,” begins a recent TED-Ed lesson by advertising account manager Brandon Rodriguez. “It could be whatever you want, made from anything you choose, in any shape or size.” While having the freedom to explore your imagination to come up with an invention of your choice might seem liberating, Rodriguez said most people are, in fact, paralyzed when faced with such a challenge. Without any […]

Avoid City Pollution by Taking Side Streets

A new study has revealed that simply taking side streets while walking through a city can cut an individual’s exposure to air pollution by half – and providing pedestrians with specific guidelines to avoid high-traffic routes could significantly benefit public health. According to the World Health Organization, air pollution is now the “world’s largest single environmental health risk” – especially since 80 percent of the global urban population residing in […]

Are Chemicals Disrupting Our Hormones?

With health concerns like obesity, cancer, and diabetes on the rise and declining sperm counts and fertility rates, scientists are starting to take a hard look at the environmental factors that may be contributing to these issues. One theory is that otherwise “safe” chemicals are disrupting our endocrine systems – impacting normal functions regulated by hormones, including reproduction, metabolism, puberty, and more. While humans are exposed to hundreds of chemicals […]

Scientists claim native Australian plants may offer a potential cure for Zika virus

A potential cure for the Zika virus has been discovered by Queensland researchers, using compounds sourced from a native Australian plant. Through a partnership between Australian-based biotech company Health Focus Products Australia (HFPA), researchers from Queensland University of Technology (QUT) have discovered the compound, found in a common Australian plant, halts the virus – preventing it from replicating without causing damage to mammalian host cells. While the plant itself is […]

Making Modern-Day Night Soil

While the practice of collecting “night soil” from urban households in China to be repurposed as fertilizer in rural rice paddies might be somewhat outdated, the idea of using excrement to maintain soil fertility continues to be promoted by environmentalists around the world. Over the last fifteen years, humanure has become a more mainstream topic – with community groups throughout the United States urging their neighbours and municipal governments to […]

SCC Urged to Reconsider Decision to Chop Down Fruit Trees in UFS

Western Australia Councilor Chris Cornish is urging the Sunshine Coast Council (SCC) to consider reducing the red tape around verge gardens – after council workers cut down 18 fruit trees in the Urban Food Streets (UFS) precinct at Buderim. The gardens span 11 streets and provide sufficient produce to feed approximately 200 households – but the council has decided that if residents do not obtain free permits and take out […]
