The authors first looked at how oxygen deprivation and cold shock interact. They found that, while an atmosphere of pure nitrogen was toxic for the worms at room temperature, decreasing oxygen ...

Doctors already use cooling to prevent brain damage in oxygen-deprived infants, but whether low oxygen also confers protection against the cold — or whether high oxygen is more toxic to humans in low ...

Using CRISPR, the researchers removed, one at a time, more than 20,000 different genes from human cells grown in the lab and then compared the growth of each group of cells at 21 percent oxygen ...

The oxygen consumption rate in the presence of 150 μg/L copper decreased by 16% at 20 °C and by 50% at 25 °C. Thus, high temperatures may increase the toxicity of copper, and possibly other metals, to ...

A council is set to give up ownership of a lake after inspectors found high levels of toxicity in the water ... and fish were moved from the lake in 2023 because of the lack of oxygen in the water.
