Record ozone loss during 2006 over South Pole

...ed with ozone-rich air outside it. Envisat, the largest Earth observation satellite ever built, can localise ozone depletion and track its changes, enabling the rapid estimation of UV radiation as well as providing forecasting. The three atmospheric instruments aboard Envisat are the Scanning Imaging Abso...

Peering into the shadow world of RNA

...epetitive sequences of DNA called transposons. The largest class of transposons, known as retrotransposons, have the remarkable ability to copy themselves into RNA, translate themselves back into DNA, and then reinsert themselves back into the DNA at the new location. If their insertion spot happens to be wi...

Researchers link ocean organisms with increased cloud cover and potential climate change

...ol of Earth and Atmospheric Sciences. "One of the largest uncertainties right now in climate models is the ability to predict how clouds would respond to changing particle levels ?whether they originate from humans with air pollution or from biological activity. We can now see very strongly the influence o...

Researchers develop technologies to devour food pathogens

...ghly effective at killing microbial pathogens. The largest obstacle remaining is optimizing the system to dispense the appropriate amount of chlorine dioxide, Morgan said. Enough of the gas must be deployed to kill the pathogens, but too much can cause a decrease of quality in the product, such as browning o...

Firefighters face increased risk for certain cancers
