For years, banned air pollutants that damage the ozone layer have been coming out of eastern China. Using the same atmospheric monitoring network that first detected the pollution, scientists recently found that the emissions from the country have now largely stopped.

A Sweet Solution for Preserving Vaccines

Researchers at McMaster University have developed a novel method for stabilizing vaccines, removing the strict requirement that the components be maintained within a specific low temperature range from development through delivery. The technique is based on drying the vaccines using two FDA-approved sugars and was shown to be successful in preserving vaccine effectiveness at elevated temperatures for twelve weeks. While it must still be validated on other vaccines, this method could be a major step toward cheap, accessible immunization in developing areas.
