Indoor farming takes root at University of Toronto - Mississauga

At University of Toronto Mississauga, a plastic tower sprouts produce including curly starbor kale, buttercrunch and collard greens.

Rising almost six feet off the ground and illuminated by high output fluorescent bulbs, the indoor farm wall grows plants hydroponically – with nutrient solution, instead of soil. The water nourishes the roots, collects in a gutter and then recirculates back to a nutrient tank that feeds back into the hydroponic system.

Eating healthier food could reduce greenhouse gas emissions

You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.

UNC-Chapel Hill study: "no fat" or "no sugar" label equals no guarantee of nutritional quality

Terms such as no-fat or no-sugar, low-fat or reduced-salt on food packaging may give consumers a sense of confidence before they purchase, but these claims rarely reflect the actual nutritional quality of the food, according to a new study led by researchers at the University of North Carolina at Chapel Hill.

Measures of poverty and well-being still ignore the environment - this must change

Orthodox economic measures like Gross Domestic product fail to measure the things that matter most, write Judith Schleicher & Bhaskar Vira: like human wellbeing and ecological health. This creates a systematic bias in 'development' policies that must urgently be addressed if we are to build an inclusive, equitable and sustainable society

Without nature, humans could be neither healthy nor happy.

Study: Cold Climates and Ocean Carbon Sequestration

We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages.

The overall goal of the work is to better understand how and why the earth goes through periodic climate change, which could shed light on how man-made factors could affect the global climate.

NASA Spots Sub-Tropical Storm 11S Still Swirling

Once a tropical storm, now a sub-tropical storm, the remnants of the tropical low pressure area formerly known as 11S was spotted by NASA's Aqua satellite, still spinning in the Southern Indian Ocean.

On March 14 at 2230 UTC (6:30 p.m. EST) the remnants of Tropical Cyclone 11S were located near 29.8 degrees south latitude and 52.4 degrees east longitude, about 530 nautical miles south-southwest of La Reunion Island.

When the sea ice melts, juvenile polar cod may go hungry

Polar cod fulfil a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones. Under the ice of the central Arctic, the juvenile fish are indirectly but heavily dependent on ice algae. As a result, retreating sea ice could have far-reaching impacts on the food web. Though researchers have long since suspected this relation existed, an international team of researchers led by the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research, have now successfully confirmed it.

Optical fingerprints can reveal environmental gases

More efficient sensors are needed to be able to detect environmental pollution. Researchers at Chalmers University of Technology have proposed a new, sophisticated method of detecting molecules with sensors based on ultra-thin nanomaterials. The novel method could improve environmental sensing in the future. The results are published in the scientific journal Nature Communications.

“This could open up new possibilities for the detection of environmental gases. Our method is more robust than conventional sensors, which rely on small changes in optical properties”, says Maja Feierabend, PhD student at the Department of Physics and the main author of the article from Chalmers University of Technology and Technische Universität Berlin.

Between a rock and an artistic place

Kamilo Beach is, arguably, the world’s dirtiest beach. Located on the southeastern coast on the island of Hawaii, the beach’s sands are littered with marine debris – most of it plastic waste washed up from the Great Pacific Garbage Patch. Among this garbage, Patricia Corcoran and Kelly Jazvac have discovered something new.

Study quantifies role of legacy phosphorus in reduced water quality

For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin–Madison reveals that a “legacy” of abundant soil phosphorus in the Yahara watershed of Southern Wisconsin has a large, direct and long-lasting impact on water quality.
