Ordinarily, if it's suspected that toxic airborne chemicals may be present in a given area, the analysis process can take several days. Now, however, scientists have developed a device that they claim can analyze the air within 10 seconds.

Though it seems empty, the intergalactic medium (IGM) actually contains more matter than galaxies do. Now, astronomers have used simulations to reveal new details about the structure of this matter, showing that “intergalactic pancakes” spanning millions of light-years collapse into a cosmic fog.

A study has affirmed the anesthetic xenon can help prevent long-term damage associated with traumatic brain injury (TBI). The research demonstrated in mice that if xenon is administered within a few hours of a TBI it can prevent brain tissue damage that would result in long-term cognitive problems.

The ExoMars Trace Gas Orbiter (TGO) has made a map of the distribution of watery minerals in the Martian surface, studied how the global dust storm affected the atmosphere, and intriguingly found very little methane, which calls into question the results of a study just last week.

The mystery of methane on Mars has been wafting around for decades. Now, using data gathered by the ESA's Mars Express orbiter and NASA's Curiosity rover on the ground, a new study has not only confirmed that the gas is there, but identified its likely source.

Researchers at the University of New South Wales (UNSW) Canberra have tested a new method for sterilizing water using hot bubbles of carbon dioxide, which they've found to be both effective and efficient.

Capturing carbon from the air and sequestering it is emerging as a viable strategy, and now scientists have developed a new method to turn CO2 gas back into solid coal, that can then be buried, or even used for electronic components.

The US Department of the Interior has announced the discovery of the largest continuous oil and gas field ever found, estimated to contain 46.3 billion barrels of oil, 281 trillion ft³ of natural gas, and 20 billion barrels of natural gas liquids.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) observatory in Chile have imaged a very active black hole at the center of spiral galaxy M77, which is apparently feasting on the universe’s largest donut.

​An innovative ingestible capsule, designed to measure gases inside the gut, has just passed phase one human trials. The swallowable sensor could reframe how gastrointestinal disorders are diagnosed as well as offering a new insight into the activity of crucial bacteria in our gut microbiome.

​Scientists believe they’ve spotted the biggest wave ever discovered. This is a tad bigger than anything you’d find on Earth: this wave is roiling through an extremely hot gas cloud in the Perseus cluster and stretches 200,000 light-years across, meaning it’s twice the size of the Milky Way galaxy.

A Duke University study suggests that serpentinized rocks underneath the ocean floor may hold the key to finding an abundant and free hydrogen resource.
