Three years ago, when Carleton architecture student and national team whitewater kayaker, Ben Hayward, took time off from his studies to train and compete in Europe in a bid to qualify for the 2016 Olympics in Rio, the cost of accommodation and travel was tough to manage on his amateur athlete’s budget.

So Hayward bought a used flatbed truck for just over $2,000 and, with $7,500 in materials and help from a Welsh mechanic friend, built a 72-square-foot wooden camper with a small wind turbine, solar panels and a round door at the back. He lived in the “Hobbit Van” for two years, driving from country to country to attend races, sleeping in parking lots.

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.

As Earth’s climate continues to warm, the urban heat island effect raises concerns that city-dwellers will suffer more heat stress than their rural counterparts. However, new research suggests that some cities actually experience a cooling effect. 

More than 60 percent of urban areas in India experience a day-time cooling effect, according to the study, which was published in Scientific Reports. The cooling effect has been observed in the past, but this paper is the first to directly identify a cause: lack of moisture and vegetation in non-urban areas surrounding the city.

Microorganisms living in the sediments buried below the seafloor obtain their nutrients by using secreted enzymes to degrade adsorbed detritus. A new study shows that in order to survive for long time scales, microorganisms eat one another after they die.

McMaster researchers are investigating how lead poisoning affected human health in the Roman Empire.

The research, jointly led by Tracy Prowse, an associate professor in McMaster's Department of Anthropology and Professor Maureen Carroll from the University of Sheffield’s Department of Archaeology, is the first study to investigate lead production and use in the Roman Empire, using archaeological and skeletal evidence from a specific site in Roman Italy.
