Without oxygen Earth early microbes relied arsenic sustain life
2020/10/16
Much of life on Earth today relies on oxygen to exist, but before oxygen was present on our planet, lifeforms likely used arsenic. The findings of the U.S. National Science Foundation-funded rese...
In 2010, a research team garnered attention when it published evidence of finding the first animals living in permanently anoxic conditions at the bottom of the sea. But a new study, led by scientists...
First-principles study on the magnetic properties in Mg dooped BiFeO3 with and without oxygen vacancies
