Scientists have discovered that treating fresh produce with ozone increases its resistance...

We've all done it – thrown out fruit or vegetables because they went rotten. Fungal contamination is the most common cause of spoilage of fresh produce, with an estimated 30 percent of harvested fruit and veggies falling victim to it. Countermeasures currently including synthetic fungicides and pre-package sanitation treatments involving the use of chlorine or bromine. Now a team of scientists from Britain's Newcastle University have discovered that much more effective and human-friendly results can be obtained by treating produce with ozone.  Read More

Activated carbon cloth could find its way into a variety of filtration applications

Researchers have discovered that activated carbon cloth is very effective at filtering harmful compounds out of air and liquids. The material was first developed in the 1980s, to protect British soldiers from chemical attacks. It is still in use today, in chemical, biological and radiological warfare suits for the military. This recent study, however, indicates that it could have a number of other uses.  Read More

Just under a year ago we reported on a method to clean polluted water and soil by infusing them with pressurized ozone gas microbubbles. The process was developed by Andy Hong at the University of Utah and has now moved out of the lab and is being put the test in a demonstration project in eastern China. If all goes to plan the process has the potential to boost a wide range of environmental cleanup efforts around the world.  Read More

A new report suggests that international efforts to halt the destruction of the ozone layer have been successful. Launched on the UN International Day for Preservation of the Ozone Layer, the report by 300 scientists also provides new information about the net effects on Earth's climate, and also the effects of climate change on the ozone later moving forward.  Read More

You'd think the healing of the hole in the ozone layer would be good news, but it seems that although every cloud is said to have a silver lining, they also have a gray one as well. The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but researchers now argue that the ozone hole over Antarctica helped to shield this region from carbon-induced warming over the past two decades and its repair could actually increase warming in the southern hemisphere.  Read More
