New research reveals that four new human-made gases have been discovered in the atmosphere. 74,000 tons of these new CFCs and HCFCs are all contributing to the destruction of the ozone layer. Emission increases of this scale have not been seen for any other CFCs since controls were introduced during the 1990s.
A new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus and other drug-resistant bacteria that threaten public health has been discovered by a team of chemists.
Using iron ions and chemistry found in the adhesive proteins of a certain mollusk, scientists have developed a hydrogel actuator that moves when its pH is raised. Hydrogels are soft networks of polymers with high water content, like jello. Because of their soft, gentle texture, they have the potential to interact safely with living tissues […]
