Microbes convert industrial waste gases into commodity chemicals | Science

Chemicals cost more than just money: Today, petrochemical production spews out nearly 2% of the world’s greenhouse gas emissions. Now, researchers have taken an important step to vastly reduce that footprint, by using bacteria and waste gases from steel plants, rather than petroleum, as the starting ingredient for dozens of commodity chemicals. So far, the … Read more

Invisible Air Pollution in The Country May Be Just as Toxic as The Smog of The City

It’s easy to see air pollution when it settles as smog over a city. Yet even in rural areas, where the air looks clearer, researchers have found unhealthy particles floating in the atmosphere.   That sweet country air may not be as invigorating as we once thought. Fine particulate matter less than 2.5 micrometers in … Read more

How to Destroy ‘Forever Chemicals’

Perfluorinated and polyfluorinated alkyl substances, or PFASs, are considered indestructible chemicals. They are virtually nondegradable and accumulate in humans and the environment. Suspected health effects include asthma, cancer and changes in the reproductive organs. How to get rid of PFASs has been completely unclear until now—and the first approaches to destroying the resistant molecules are … Read more

We Have Breached The Safe Planetary Limit For Synthetic Chemicals, Scientists Warn

From sea to land to sky, Earth’s systems are contaminated with synthetic substances, and scientists warn it has already pushed the integrity of our planet over the brink. Today, there are about 350,000 human-made chemicals on the market, including plastics, pesticides, industrial chemicals, cosmetic chemicals, antibiotics, and other drugs.   The fact this number continues … Read more

NASA’s Perseverance rover finds organic chemicals on Mars

NASA’s Perseverance Mars rover has found life’s building blocks on the Red Planet. Perseverance has identified carbon-containing organic chemicals in some of the rocks it has examined on the floor of Mars’ Jezero Crater, mission team members announced on Wednesday (Dec. 15).  To be clear: This is not a detection of Mars life. Organics can … Read more

Chemical Air Pollution Morphs Into Something Even More Toxic, Study Shows

Remnants of industrial chemicals in the air can potentially transform into new substances more toxic and persistent than the original pollution, according to a global study published on Wednesday.   Using samples gathered around the world, the study published in Nature found that these previously unidentified products are present in the atmospheres of 18 big … Read more
