Transforming restaurant waste into fuel

When most people look at discarded vegetable oil—browned and gritty from frying food—they likely see nothing more than waste.

But to Ajay Dalai, a professor in the Department of Chemical and Biological Engineering, the cooking process creates a byproduct that has newfound potential as a source of fuel and biolubricant.

The invisible clean-up crew: Engineering microbial cultures to destroy pollutants

University of Toronto engineering professor Elizabeth Edwards is internationally recognized for using biotechnology to clean up industrial solvents in soil and groundwater. Her technique earned her the prestigious Killam Prize in 2016 and has already been used to restore more than 500 sites around the world.

Fifth of food lost to over-eating and waste

Almost 20 per cent of the food made available to consumers is lost through over-eating or waste, a study suggests. 

The world population consumes around 10 per cent more food than it needs, while almost nine per cent is thrown away or left to spoil, researchers say.

Efforts to reduce the billions of tonnes lost could improve global food security – ensuring everyone has access to a safe, affordable, nutritious diet – and help prevent damage to the environment, the team says.

NASA's Fermi Finds Possible Dark Matter Ties in Andromeda Galaxy

NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Dying Patients Who Received Palliative Care Visited the ER Less

Community-based palliative care – care delivered at home, not the hospital – was associated with a 50 percent reduction in emergency department visits for patients in their last year of life.  The results of an Australian study were published online February 3rd in Annals of Emergency Medicine(“The Association of Community-Based Palliative Care with Reduced Emergency Department Visits in the Last Year of Life Varies by Patient Factors”).

Winners, losers among fish when landscape undergoes change

As humans build roads, construct buildings and develop land for agriculture, freshwater ecosystems respond - but not always in the ways one might expect.

Offshore Wind Push

Injecting large amounts of offshore wind power into the U.S. electrical grid is manageable, will cut electricity costs, and will reduce pollution compared to current fossil fuel sources, according to researchers from the University of Delaware and Princeton University who have completed a first-of-its-kind simulation with the electric power industry.

Over time, nuisance flooding can cost more than extreme, infrequent events

Global climate change is being felt in many coastal communities of the United States, not always in the form of big weather disasters but as a steady drip, drip, drip of nuisance flooding.

Colorado River Flows to Keep Shrinking as Climate Warms

Warming in the 21st century reduced Colorado River flows by at least 0.5 million acre-feet, about the amount of water used by 2 million people for one year, according to new research from the University of Arizona and Colorado State University.

New URI professor examining effects of climate change on coral reefs, shellfish

The newest professor in the University of Rhode Island’s College of the Environment and Life Sciences, Hollie Putnam, thinks some corals and shellfish might have good enough “memories” to buffer the changes in ocean chemistry that are resulting from global climate change.

A native of Minnesota who earned a doctorate at the University of Hawaii, Putnam is studying how a wide variety of marine organisms are responding to changes in their environment. Focusing on reef-building corals and other shelled creatures that are threatened by increasing temperatures and ocean acidification, she is testing them to determine how species may acclimatize to the new circumstances.
