You are fucking kidding me right? These satanists (oops, I meant scientists) are diabolically insane!!!
Scientists Turn Bacteria Into DNA Tape Recorders
"By tinkering with its DNA, scientists have converted the common gut
bacterium E. coli into the world’s smallest tape recorder. The newly
designed microbes are engineered in such a way that they are capable
of documenting and storing memories from their environment which can
then be retrieved at a later date. The idea behind these living data
storage devices is that one day, they could be used as tiny health
monitors or environmental sensors.
Scientists have attempted to store useful information in bacterial DNA
before, but only managed to successfully record
all-or-nothingmemories, such as whether a particular stimulus is
present in the environment or not. These digital memories could not
therefore inform us of how long the exposure was, or how much of the
stimulus was present, i.e. analog information. These new cells,
however, are capable of doing just that.
To create their living memory recorders, scientists from the
Massachusetts Institute of Technology(MIT) turned to sequences of DNA
found in certain species of bacteria called retrons. Retrons carry the
genetic information for the production of enzymes (biological
catalysts) which generate single strands of DNA that are then inserted
into the bacterium’s genome. Usually, these strands are used by the
bacteria to manipulate their host.
By tinkering with their DNA sequence, the researchers were able to
make retrons that only produce unique DNA sequences when a particular
stimulus, such as light or a chemical, is present. These strands,
which are effectively a record of the experience, are then inserted
into a specific target site within the genome.
“We can target it anywhere in the genome,” says lead scientist Timothy
Lu, “which is why we’re viewing it as a tape recorder, because you can
direct it where that signal is written.”
Because the sequence can be passed on from generation to generation,
the memory gradually accumulates and is stored for the lifetime of the
population. Scientists can then recover this stored information by
sequencing the genome of the organism. By determining how many of the
cells within the population contain the new DNA sequence, they can
work out the magnitude and duration of the signal. The higher the
proportion containing the sequence, the greater the exposure.
The ultimate goal for the researchers is to use this system as a
monitoring device for different environments. Because scientists can
design the cells to respond to a variety of different stimuli,
the potential applications are vast. The organisms could be placed in
the ocean to measure levels of CO2 or pollution, for example.
Alternatively, they could be used in medicine to monitor disease
progression, such as the spread of cancers, by picking up stimuli that
are released by diseased cells."
