A scare from New Scientist: Melting permafrost could release ancient viruses that cause the next pandemic

The basis for such panic marketing is usually a correct science observation — in this case, that microscopic life forms (and viruses) may hibernate for long periods in ice. However, as the New Scientist article notes, “bacteria that infect humans are adapted to live at our body temperatures, so it is highly unlikely that they would survive for long periods below zero.”

At Scientific American: How some bacteria have achieved “immortality”

At Scientific American: In this experiment, cells awoke and multiplied that settled to the bottom when pterosaurs and plesiosaurs drifted overhead. Four geologic periods had ground by, but these microbes, protected from radiation and cosmic rays by a thick coat of ocean and sediment, quietly persisted. And now, when offered a bite, they awoke and carried on as if nothing unusual had happened.

Bacterium alters its genome to adapt to new conditions

Researchers: Achromatium is special in many respects: It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes.
