Ozone

A new study has revealed that ozone levels in the heavily populated lower latitudes don't seem to be recovering as well as regions near the poles. Although there isn't yet a clear explanation as to why this is happening, blame may still rest on short-lived ozone-destroying chemicals.

It’s long been known that the hole in the ozone layer is shrinking, but a new study has provided greater insight into the improving health of the ozone layer by analyzing the chemicals around the hole over the last decade or so.

According to a new study, evidence of alien life in the atmospheres of potentially habitable exoplanets could be hidden from telescopic eyes by unusual air flow patterns. The research could have significant implications regarding how astronomers carry out their search for extraterrestrial life.

It is expected to prevent 280 million cases of skin cancer in the US alone. Without it, the sun would burn skin in minutes. Yet the strides made by the Montreal Protocol in repairing our ozone layer may be undone thanks to dangerous chemicals now making their way into the upper atmosphere.

As many cities around the world become greener with plant-clad towers, vertical gardens and tree-filled urban developments, a recent study has revealed that during heat waves, trees in a city can actually contribute to higher levels of air pollution.

The Roving Blue O-Pen supports world travellers and nomads by keeping drinking water clean and fresh. In contrast to more common purification means, like UV rays, this pen-sized purification device kills microorganisms with the stuff that blocks those UV rays in the atmosphere: ozone.

In the 1980s, pretty much every country in the world agreed to ban the use of CFCs, a decision that is now paying big dividends with scientists reporting significant shrinkage of the hole in the ozone layer and evidence of what looks to be a path to recovery.

ScienceA new study by MIT has revealed that the quantities of nitrous oxide (N2O), otherwise known as laughing gas, being released by the world's oceans has been dramatically underestimated.
-
ScienceA new study has examined the potentially disastrous implications that a combination of global warming and air pollution could have on crop yields by the year 2050.

Researchers have discovered that activated carbon cloth is highly effective at removing pollutants from air and liquid.

The method to clean polluted water and soil by infusing them with pressurized ozone gas microbubbles we reported on last year has now moved out of the lab and is being put the test in a demonstration project in eastern China.
