A family's day with Tungsten
After the X-ray she
has to wait some time in the waiting room, where she finds some scientific
journals. The dentist is obviously very interested in science and wants to give
his patients a chance to read about the newest research while waiting for their
treatment. Curiously enough she finds an article about the role of Tungsten in
the generation of early life.
According to this
article it can be assumed that Tungsten plays an important role in enzymes
necessary for bacteria having lived near submarine volcanic vents at elevated
temperatures. Later on in evolution, the Tungsten was substituted by
Molybdenum. Today we only can find Tungsten as an essential element in
anaerobic bacteria. This seems to be a leftover from ancient times, because the
aforementioned cells also lived under the exclusion of Oxygen.
