The trucks and trains that transport goods across the United States emit gases and particles that threaten human health and the environment. 

Scientists have created flags that can generate electrical energy using wind and solar power.

As climate change melts Greenland’s glaciers and deposits more river sediment on its shores, an international group of researchers has identified one unforeseen economic opportunity for the Arctic nation: exporting excess sand and gravel abroad, where raw materials for infrastructure are in high demand.

The Arctic is warming twice as fast as the rest of the planet. One consequence of that trend is the thawing of permafrost, a layer of earth that has remained frozen for thousands of years in some areas. 

A field survey conducted by a team of marine scientists from the National University of Singapore (NUS) has uncovered toxic bacteria living on the surfaces of microplastics, which are pieces of plastic smaller than 5 millimetres in size, collected from the coastal areas of Singapore. 

A James Cook University scientist says the last coastal stronghold of an iconic predator, the endangered Bengal tiger, could be destroyed by climate change and rising sea levels over the next 50 years.

Before the 2014 Toledo Water Crisis left half a million residents without safe drinking water for three days, Dr. Jason Huntley’s research at The University of Toledo focused on bacteria that cause pneumonia.

Humans have a "disproportionately huge effect" on the other species of vertebrates that share Earth's surface with us, causing more than 25 percent of the deaths among an array of species all over the globe, according to a recently published study.

Radiotelemetry is the use of tiny radio transmitters, worn by animals, which emit radio waves that can be detected several hundred meters away.

While completing her master’s degree in biology in York University’s Faculty of Science, Julia Gauberg spent three months in Australia trying to figure out how a particular fungus is causing the death of so many Australian green tree frogs and other amphibians around the world.
