The Canadian government announced it will spend $4.5 billion ($3.5 billion USD) to buy the beleaguered Trans Mountain pipeline expansion project. The expansion plan — which would triple the volume of oil being carried from Alberta’s tar sands to an export terminal near Vancouver, from 300,000 barrels a day to 890,000 — has faced years of fierce opposition from environmentalists and some indigenous groups.

Limiting global warming to 1.5°C could avoid around 3.3 million cases of dengue fever per year in Latin America and the Caribbean alone - according to new research from the University of East Anglia (UEA).

Certain types of bacteria and viruses are readily ejected into the atmosphere when waves break while other taxa are less likely to be transported by sea spray into the air, researchers reported May 22.

South Asia is in the midst of an intense, weeks-long bout of heat and extreme weather. For the last four days, daytime temperatures in Karachi, Pakistan hovered around 111 degrees Fahrenheit. At least 65 people have died so far and widespread power outages threaten the health of tens of thousands of others. Forecasters predict the heat wave will continue into June, with temperatures soaring to 122 degrees in the coming days.

Diverse neighbors. Health centers. Commuter trains. These community attributes, and other key factors, are linked to well-being and quality of life, according to Yale researchers.

Glioblastoma multiforme, a type of brain tumor, is one of the most difficult-to-treat cancers. Only a handful of drugs are approved to treat glioblastoma, and the median life expectancy for patients diagnosed with the disease is less than 15 months.

The annual federal report on toxic material emissions from industrial sites across the country gains widespread media attention and serves as a reminder of the potential environmental impacts of industrial activities.

A lot can happen at 160 degrees Fahrenheit: Eggs fry, salmonella bacteria dies, and human skin will suffer third-degree burns. If a car is parked in the sun on a hot summer day, its dashboard can hit about 160 degrees in about an hour. One hour is also about how long it can take for a young child trapped in a car to suffer heat injury or even die from hyperthermia.

The main type of “bunker” oil for ships is heavy fuel oil, derived as a residue from crude oil distillation. Crude oil contains sulphur which, following combustion in the engine, ends up in ship emissions. Sulphur oxides (SO_x) are known to be harmful to human health, causing respiratory symptoms and lung disease. In the atmosphere, SO_x can lead to acid rain, which can harm crops, forests and aquatic species, and contributes to the acidification of the oceans.

Limiting SO_x emissions from ships will improve air quality and protects the environment.

A new University of Guelph study has discovered why exposure to pesticides increases some people’s risk of developing Parkinson’s disease.
