A newly evolved enzyme could one day make silicone compounds biodegradable. For the first time, scientists have engineered an enzyme that can break stubborn human-made bonds between silicon and carbon ...
For the first time, scientists have engineered an enzyme that can break stubborn man-made bonds between silicon and carbon that exist in widely used chemicals known as siloxanes, or silicones. The ...

Massive Burps of Carbon Dioxide Led to Oxygen-less Ocean Environments in the Deep Past
Oxygen (O 2) is a chemical element. At standard temperature and pressure, two oxygen atoms bind together to form a colourless and odourless gas with a molecular mass of 32 atomic mass units (amu). Together with nitrogen and argon, oxygen is one of the three major constituents of Earth’s atmosphere, being present in 21% of air.
Medical oxygen is a life-saving medicine that is used to treat many conditions throughout the care continuum. Despite the clinical importance of medical oxygen and inclusion on the WHO Essential Medicines List, it remains a hard to access resource in health care settings. The COVID-19 pandemic highlighted inequities in availability and access to this life-saving medicine and the inherent ...
