Using drones to monitor volcanoes: Researchers analyze volcanic gases with the help of…
The main gases released by volcanoes are water vapor, carbon dioxide, and sulfur dioxide. Analyzing these gases is one of the best ways of obtaining information on volcanic systems and the magmatic processes that are underway. The ratio of…
Imaging gases in rainbow colors: Development of a pressure-sensitive device capable of…
NIMS, Harvard University and the University of Connecticut have designed and fabricated a simple device capable of imaging a gas injected into it in multiple colors in accordance with its gaseous properties, enabling chromatic…
Curved spacetime in the lab: Researchers simulate an entire family of universes with curvature in…
In a laboratory experiment, researchers from Heidelberg University have succeeded in realising an effective spacetime that can be manipulated. In their research on ultracold quantum gases, they were able to simulate an entire family of…
A billionaire emits a million times more greenhouse gases than average person: Oxfam report
The investments of 125 of the world's richest billionaires yield an annual average of three million tonnes of carbon dioxide emissions a year, more than a million times the average for someone in the bottom 90 per cent of humanity,…
A simple, cheap material for carbon capture, perhaps from tailpipes: Porous material from melamine…
Using an inexpensive polymer called melamine -- the main component of Formica -- chemists have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks, a key goal for the United States and other nations as…
Porous crystals bind fluorine-containing greenhouse gases: Researchers develop new crystalline…
Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases -- including so-called per- or polyfluorinated hydrocarbons, or PFCs -- have a significant share in…
Russia Limits Exports of Noble Gases, a Key Ingredient for Making Chips
The Russian flag is seen behind a razor wire fence. (File photo: Reuters)Exports of noble gases, which Russia used to supply to Japan and other countries, will be allowed only with special state permission until Dec. 31, the Russian…
Oilsands companies are emitting more climate-changing gases than ever | CBC News
Our planet is changing. So is our journalism. This weekly newsletter is part of a CBC News initiative entitled "Our Changing Planet" to show and explain the effects of climate change. Keep up with the latest news on our Climate and…
Rocket engine exhaust pollution extends high into Earth’s atmosphere: Understanding rocket…
Reusable space technology has led to a rise in space transportation at a lower cost, as popularized by commercial spaceflights of companies like SpaceX and Virgin Galactic. What is poorly understood, however, is rockets' propulsion…
