Crystallized water could exist in Earth’s lower mantle

According to a study, water could be hidden hundreds of miles under the Earth’s surface – but in the form of crystallized water. While oceans have maximum depths of at least seven miles, water is known to exist well below these levels. In fact, ongoing research is still trying to confirm “[just] how deep this hidden […]

Reusing CO2: Scientists are closer to converting it to clean energy

Nature emits carbon dioxide (CO2) as part of many different natural processes. Plants are known to take them in as a necessary ingredient in photosynthesis, and it benefits the Earth in a lot of different ways, such as accelerating plant growth and food production. Although the planet’s CO2 levels are currently near record lows throughout […]

Tracking wastewater is difficult: Artificial sweeteners turn out to be reliable chemical markers

No one really thinks twice about the wastewater generated by sinks and toilets, but a team of Canadian scientists has recently discovered an unusual way to track the water “to ensure it doesn’t end up in unwanted places.” John Spoelstra, a research scientist with Environment and Climate Change Canada, says that artificial sweeteners “are very specific […]

Technical solutions for pulling pollution out of the air are distractions that allow both government and industry to keep polluting

The global air pollution situation has peaked, causing millions to succumb respiratory issues and other health problems. Various countries have attempted to tackle this worldwide epidemic through all kinds of creative means. In Xi’an, China, a tower the size of a small high-rise is said to purify the air around it. In London, a group […]

California’s Central Valley food production found responsible for shocking amount of air pollution

A new study that was conducted by researchers from the University of California, Davis recently concluded that a large part of the nitrogen oxide pollution found in California comes from a rather unexpected source: Heavy fertilizer use in the California Central Valley region, which is said to be the source of more than half of […]

Removing heavy metals from water: Activated charcoal from palm kernel cake is a low cost biosorbent

Contaminated water contains all sorts of harmful toxins that can result in dangerous diseases in humans. This has led scientists to devise various ways to decontaminate water —-so much so that decontamination has become an industry of its own. One of the primary objectives of decontamination is to remove heavy metals in water, which can cause […]

Scientists find improved approach for creating fuel from biowaste, making it a good substitute for fossil fuels

It seems like every day, researchers find yet another fossil fuel alternative. Not that anyone should be complaining. This time, a team of researchers from the University of Calgary have developed a method to produce a much higher quality and more stable fuel from biowaste, such as raw sewage, which is simpler and a lot […]

Powering clean air: The world’s first power plant with negative emissions now in operation

It’s practically a given at this point that whenever a power plant is in operation, it is inevitably going to have at least some emissions. After all, the waste material from what’s being produced inside has to be expelled somewhere. But did you know that it’s possible for a power plant to have less than […]

Millions of documents about chemical toxicity have been compiled into database, ToxicDocs, now available online

There is no doubt that toxic products are everywhere you look these days. For every headline about a product recall, there are countless other items that are either ignored or given a free pass, slowly poisoning us and our planet. Public health historians David Rosner and Gerald Markowitz have been documenting the history of toxic […]

Man-made meteor: New estimates put China’s doomed space station, with toxic chemicals on board, crash landing back to Earth in about 3 months — with many toxins surviving re-entry

In 2016, the Chinese Space Agency conceded that it had lost contact and control of the Tiagong-1, China’s first prototype space station. Officials hypothesized that reentry into the Earth’s atmosphere would occur sometime in 2017. Now, it has been estimated that the Tiagong-1 — which means “Heavenly Place — will finally crash into the earth […]
