Fox Creek Quakes Linked to Volume and Location of Hydraulic Fracturing

The volume of hydraulic fracturing fluid and the location of well pads control the occurrence and frequency of measurable earthquakes, new research from the Alberta Geological Survey and the University of Alberta shows.

More roads in grizzly bear habitat means more deaths

It’s simple math, says a University of Alberta conservation biologist. More roads equals fewer grizzly bears.In a recent study examining a non-invasive DNA (hair collection) dataset of grizzly bear activity in British Columbia, Clayton Lamb and his colleagues determined what scientists have long suspected: higher road density leads to lower grizzly bear density—a critical problem for a species still rebounding from a long period of human persecution.

Cattle delayed a weekend before slaughter produce lower-grade meat

When cattle arrive at a slaughterhouse on a Friday but are held for processing until Monday, they have an increased incidence of producing tough, low-grade meat, new research shows.“It can happen if there are too many cattle and there’s a backup, or if there’s a plant breakdown,” said Heather Bruce, an associate professor of carcass and meat science in the Faculty of Agricultural, Life & Environmental Sciences.

New technology capable of converting waste into bio-energy coming to University of Alberta

A shipping container-sized pilot plant that can process a variety of wastes into valuable biofuels will be shipped from Germany to Edmonton thanks to a new future energy research collaboration between the University of Alberta and Germany’s Fraunhofer Society.The plant, known as Biobattery, uses thermo-catalytic reforming (TCR) technology developed by Fraunhofer bioengineering researcher Andreas Hornung to process a variety of wastes into three valuable products––bio-oil, char and gases––at a rate of 30 kilograms per hour.

Best way to save the caribou? Look at white-tailed deer and moose

The most effective way to save North America’s dwindling caribou herds is to keep numbers of invading prey animals—like deer and moose—low, according to a new UAlberta research study.“Prey like moose and deer are expanding in numbers and range because of logging and climate change,” said Robert Serrouya, a postdoctoral fellow in biological sciences professor Stan Boutin’s lab.

Are cashiers at risk of dangerous chemical exposure through paper?

People who handle paper receipts regularly may be at increased risk for exposure to a chemical linked to breast and prostate cancers, according to new UAlberta research.“We found that people who handled receipts printed on thermal paper containing the chemical had it lingering in their body for a week or more,” said Jiaying Liu, a PhD candidate in UAlberta’s Department of Laboratory Medicine and Pathology.

Tree's chemistry puts mountain pine beetle in sticky situation

A University of Alberta forestry professor has cracked a key mystery surrounding the mountain pine beetle.After studying lodgepole pine trees in the Grande Prairie area that survived a pine beetle attack, U of A professor Nadir Erbilgin and his team discovered certain chemicals in the trees that produce high levels of resin—sticky sap—that overwhelms the insect.
