Read the text and answer the question. Scientists store entire human genome on ‘memory
crystal’ that could survive billions of years By Rosa Rahimi, CNN. Published 7:53 AM EDT, Fri September 20, 2024 The crystal features a visual key, intended to explain what it contains to
whoever finds it. University of Southampton/PA Scientists in the United Kingdom have stored the
entire human genome on a “5D memory crystal,” in the
hope that it could be used in the future as a blueprint to
bring humanity back from extinction. The crystal, which was developed by a team of
researchers at the University of Southampton’s
Optoelectronics Research Centre, could also be used to
create a record of plant and animal species faced with
extinction. It can hold up to 360 terabytes of information for
billions of years and can withstand extreme conditions,
including freezing, fires, direct impact force, cosmic
radiation and temperatures of up to 1,000 degrees
Celsius, the university said in a press statement
published Thursday. In 2014, the crystal was awarded the Guinness World
Record for “most durable digital storage material.”
Kazansky’s team used ultra-fast lasers to inscribe the
human genome data into voids as small as 20
nanometers (a nanometer is about one-billionth of a
meter). They describe the data storage on the crystal as
5D because the information is translated into five
different dimensions of its nanostructures — their
height, length, width, orientation and position. “The 5D memory crystal opens up possibilities for
other researchers to build an everlasting repository of
genomic information from which complex organisms
like plants and animals might be restored should
science in the future allow,” said Peter Kazansky, a
professor of optoelectronics, who led the team at
Southampton. The team had to consider who – or what – would
retrieve the information, so far off into the future. It could be an intelligence (species or machine) – or it
could be found in a future so distant that no frame of
reference would exist for it. To help whoever finds it,
the researchers included a visual key. “The visual key inscribed on the crystal gives the finder
knowledge of what data is stored inside and how it
could be used,” said Kazansky. “Their work is super impressive,” said Thomas Heinis,
who leads research on DNA storage at Imperial College
London and was not involved in the study. However, he
says questions remain about how such data could be
read in the future. “What Southampton presents probably has a higher
durability, however, this begs the question: what for?
Future generations? Sure, but how will they know how
to read the crystal? How will they know how to build
the device to read the crystal? Will the device be
available in hundreds of years?” he added. “I can barely
connect my 10-year-old iPod and listen to what I
listened back then.” For now, the crystal is stored in the Memory of
Mankind archive, a time capsule within a salt cave in
Austria. In 2018, Kazansky and his team used the memory
crystal technology to store Isaac Asimov’s
“Foundation” trilogy of science fiction books, which
were then launched into space aboard a Tesla Roadster.
The technology has also been used to store major
documents from human history, including the Universal Declaration of Human Rights and the Magna Carta.
Earlier this year, scientists revealed a plan to safeguard
Earth’s species in a cryogenic biorepository on the
moon, intended to save species in the event of a disaster
on our home planet. https://edition.cnn.com/2024/09/20/science/human-genome-crystal-intl-scli/index.html
