It seems like getting something for nothing, but you really can get drinkable water right out of the driest of desert air.

Researchers at Chalmers University of Technology have shown that between 87 and 98 percent of ships comply with the tougher regulations for sulphur emissions that were introduced in northern Europe in 2015. The lowest levels of compliance were observed in the western part of the English Channel and in the middle of the Baltic Sea.

Researchers have conducted the first field tests for a new laser-based system that can pinpoint the location of very small methane leaks over an area of several square miles. The new technology could one day be used to continuously monitor for costly and dangerous methane leaks at oil and gas production sites.

Queen’s University researcher Xiaolong Yang and his research team have developed a light emission-based biosensor that uses firefly luciferase (the enzyme that allows fireflies to light up) to monitor cancer cell activity and help find new ways to fight the spread of cancer.

Tropical Cyclone Marcus continues to strengthen as it moves further away from Western Australia. NASA's Aqua satellite analyzed the system in infrared light to find the strongest part of the hurricane. 

Sweeping policies that reward people in environmentally sensitive areas for returning their farmlands to nature have been lauded as ecological triumphs. But a new Michigan State University study shows that over time some participants may become conservation martyrs.

Hummingbirds' specialization and vulnerability are often predicted based on their physical traits. Scientists now found that this is not the case for hummingbirds on the Caribbean islands. Instead, the bird's environment is the determining factor. The new study was led by scientists from Center for Macroecology, Evolution and Climate, University of Copenhagen, and published today in the scientific journal Proceedings of the Royal Society B.

It’s long been known that sharks help nourish coral reefs, but exactly to what extent has never been scientifically mapped out — until now.

MIT researchers have developed a system that can produce images of objects shrouded by fog so thick that human vision can’t penetrate it. It can also gauge the objects’ distance.

An inability to handle misty driving conditions has been one of the chief obstacles to the development of autonomous vehicular navigation systems that use visible light, which are preferable to radar-based systems for their high resolution and ability to read road signs and track lane markers. So, the MIT system could be a crucial step toward self-driving cars.

Technology developed at the University of Waterloo reliably and affordably increases the efficiency of internal combustion engines by more than 10 percent.
The product of a decade of research, this patented system for opening and closing valves could significantly reduce fuel consumption in everything from ocean-going ships to compact cars.
