A process to convert personal protective equipment (PPE) waste into harmless byproducts is a potential game changer to the problem of PPE waste filling landfills and polluting oceans and rivers.
Shredded masks, gowns, gloves and plastic safety glasses go into a machine; hot, pressurized water, and compressed air are applied; water and acetic acid are the end-products. The PPE-to-liquid process is carried out at a temperature of 300C and takes about an hour...
The massive underwater volcanic eruption in Tonga has brought heated discussions concerning how it may affect the global climate.
A research team led by Prof. Xiong Wei from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) has been monitoring and analysing the greenhouse gas concentrations before and after the volcanic eruption in Tonga with the Greenhouse Gases Monitoring Instrument (GMI).
They inverted the greenhouse gas monitoring data over Australia and New Zealand near the volcano in January...

Earth's supply of water is incredibly important for its ability to sustain life, but where did that water come from? Was it present when Earth formed or was it delivered later by meteorites or comets from outer space?
The origin of Earth's water has been a longstanding debate, and Lawrence Livermore National Laboratory (LLNL) scientists think they have the answer – and they found it by looking at rocks from the moon.
Since the Earth-moon system formed together from...
