tics that can be applied broadly in communities has never
been more urgent."
To showcase the platform's multi-diagnostic capa-
bilities, the team developed a strategy for rapidly testing
dozens of samples for the 169 human-associated viruses
that have more than 10 published genome sequences.
The researchers tested this detection panel against 58
patient samples, using multiple chips. They additionally
applied CARMEN on patient samples to differentiate be-
tween subtypes of influenza A strains and to detect drug-
resistance mutations in HIV.
The team also incorporated detection mixtures for
SARS-CoV-2—the virus that causes
COVID-19—and other respiratory patho-
gens to demonstrate, using synthetic
viral sequences, how the assay can
be rapidly adapted to detect emerging
viruses. (Source: MIT News)
Researchers have developed a new technology that
flexibly scales up CRISPR-based molecular diagnostics,
using microfluidics chips that can run thousands of tests
simultaneously. A single chip's capacity ranges from de-
tecting a single type of virus in more than 1,000 samples
at a time to searching a small number of samples for more
than 160 different viruses, including the COVID-19 virus.
Called Combinatorial Arrayed Reactions for Multiplexed
Evaluation of Nucleic acids (CARMEN), this technology—
validated on patient samples—provides same-day re-
sults and could someday be harnessed for broad public-
health efforts. The work appears in Nature.
"The current pandemic has only un-
derscored that rapid and sensitive tools
are critical for diagnosing, surveilling,
and characterizing an infection within a
population," said Pardis Sabeti, co-senior
author. "The need for innovative diagnos-

The Post-coronavirus World
Once the dust settles post-coronavirus, it's
expected many people will continue working
at least part-time remotely. A remote work-
force forecast by Global Workplace Analytics
[6]
suggests that the longer people are required
to work from home, the greater the adoption
we will see when it's all said and done with
COVID-19. The employment of all of the above
technologies will continue to serve business-
es well by protecting their networks and most
valuable data as remote work moves full steam
ahead into the future. PCB007
