Japanese researchers tinker with bacteria to store data for a
million years
JAPAN: These days, data gets stored on disks, computer chips,
hard drives and good old-fashioned paper. Scientists in Japan see
something far smaller but more durable - bacteria.
The four characters - T, C, A and G - that represent the genetic
coding in DNA work much like digital data. Character combinations can
stand for specific letters and symbols - so codes in genomes can be
translated, or read, to produce music, text, video and other content.
While ink may fade and computers may crash, bacterial information
lasts as long as a species stays alive - possibly a mind-boggling
million years - according to Professor Masaru Tomita, who heads the team
of researchers at Keio University.
Tomita’s team successfully inserted into a common bacterium Albert
Einstein’s famous “E equals MC squared” equation and “1905,” the year
the Nobel Prize-winning physicist published the special theory of
relativity.
Genetic coding is so massive that information - say, a Shakespeare
play - can be stashed away somewhere in the gene without affecting an
organism’s overall appearance and other traits.
But mutation could distort stored data. Tomita says data are stored
in four places in the bacteria so the data stay intact, though Katsumi
Doi, bacteria expert and Kyushu University professor, is skeptical.
“We may need more time for practical applications,” Doi said. “But I
love the idea.”
Translating the Einstein message would require solving the code. But
Tomita is the kind of freethinking scientist intrigued by the notion
that an extraterrestrial might come across it in the distant future -
and naturally possess the superior intelligence to quickly solve the
code.
Tomita shrugs off the obvious question: “Who in the world is going to
read bacteria?” “Many people never even thought about storing data for
thousands of years,” Tomita said. “This may sound like a dream. But
we’re thinking hundreds of millions of years.”
