International research team warns of mineral supply constraints as demand increases for green technologies

An international team of researchers, led by the University of Delaware’s Saleem Ali, says global resource governance and sharing of geoscience data is needed to address challenges facing future mineral supply.

Specifically of concern are a range of technology minerals, which are an essential ingredient in everything from laptops and cell phones to hybrid or electric cars to solar panels and copper wiring for homes. However, base metals like copper are also a matter of immense concern.

Agricultural research looks at dugouts as absorbing carbon dioxide

Three researchers at the University of Regina have been awarded a provincial research grant to study the role of agricultural dugouts in greenhouse gas capture.

Dr. Kerri Finlay, Dr. Peter Leavitt, Dr. Gavin Simpson of the biology department, along with Dr. Helen Baulch of the University of Saskatchewan, were recently awarded $255,030 from the Saskatchewan Ministry of Agriculture's Agriculture Development Fund.

Earth's first example of recycling -- its own crust!
March 17, 2017 07:22 AM - Carnegie Institute for Science

Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.  

Indoor farming takes root at University of Toronto - Mississauga
March 16, 2017 08:47 AM - University of Toronto

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
March 16, 2017 06:59 AM - Julie Cohen, UC Santa Barbara

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.

Did humans create the Sahara Desert?
March 14, 2017 11:23 AM - Frontiers via EurekAlert!

New research investigating the transition of the Sahara from a lush, green landscape 10,000 years ago to the arid conditions found today, suggests that humans may have played an active role in its desertification. 

The desertification of the Sahara has long been a target for scientists trying to understand climate and ecological tipping points. A new paper published in Frontiers in Earth Science by archeologist Dr. David Wright, from Seoul National University, challenges the conclusions of most studies done to date that point to changes in the Earth's orbit or natural changes in vegetation as the major driving forces.

Shell Begins Divestment From Canadian Oil Sands
March 14, 2017 08:51 AM - Jan Lee, Triple Pundit

Last week Royal Dutch Shell agreed to sell most of its Athabasca oil sands investment to a Canadian exploration company for $8.5 billion. To many, this was anything but a surprise. In 2015, the world’s second largest publicly-traded oil company put the brakes on its Pierre River development, suggesting it wasn’t the right time for Shell to enter what was at the time the largest oil sands development in Canada.

MSU researcher studies effects of weather variability and market dynamics on maple syrup production
March 14, 2017 08:32 AM - Montana State University

A Montana State University assistant professor of sustainable food systems who has conducted research all over the world is turning her attention to maple syrup.

Some farmers in the United States and Canada have noticed that the quantity and quality of their maple syrup is changing with climate variability, said Selena Ahmed from MSU's Department of Health and Human Development in the College of Education, Health and Human Development. Ahmed is co-leading a team of researchers who are investigating these observations.

Organic is only one ingredient in recipe for sustainable food future
March 13, 2017 08:41 AM - University of British Columbia (UBC)

Many people choose organic thinking it’s better for humans and the planet, but a new UBC study published today in Science Advances finds that might not always be the case.
