A lab in North Carolina is working to synthesize a sample of the coronavirus from its genetic code, according to MIT Technology Review.

Why it matters: Creating a pathogen from scratch would allow researchers to rapidly experiment on it without waiting for live samples from an outbreak zone. But it also raises the risk that someone could eventually try to re-create a dangerous virus as a weapon.

Driving the news: Coronavirus expert Ralph Baric at the University of North Carolina took the genetic code of the pathogen, posted online last month by Chinese researchers, and ordered custom DNA.

  • He will be able to stitch the genes together into a virus indistinguishable from the one that has infected more than 80,000 people and killed more than 2,700, MIT Tech's Antonio Regalado writes.
  • "This is the future in terms of how the medical research community responds to a new threat,” Baric told Regalado.

Background: Scientists managed to isolate and sequence the new coronavirus only two weeks after public health officials first reported the virus to the World Health Organization — far quicker than the months that passed before the virus that caused SARS was identified in 2003.

  • The cost of DNA synthesis has also fallen drastically, and many commercial companies now offer custom-made genes that can be shipped by mail.

Once they've synthesized the virus, researchers will also be able to edit it as they might a document, adding and subtracting genes in an effort to understand how it spreads and sickens people.

  • Past disease events like the 2009 H1N1 flu pandemic and the 2014 Ebola outbreak often ran their course before new countermeasures could be developed and distributed.
  • Synthesizing the virus could help health officials move almost as fast as the pathogen itself.

The catch: If a virus can be synthesized from nothing more than its genetic code and mail-order DNA, it means a deadly pathogen can never really be eliminated.

  • In 2002, researchers synthesized a poliovirus from genetic code found online, demonstrating for the first time that terrorists could theoretically create their own bioweapons with open-source information.
  • In 2017, the Canadian virologist David Evans shocked the medical community when he used the same synthetic biology tools to synthesize a close relative of the smallpox virus, which had killed hundreds of millions of people before it was declared eradicated in 1980.

The International Gene Synthesis Consortium, a group of DNA synthesis companies that screens gene orders, prohibits its members from synthesizing the gene sequences of dangerous viruses like smallpox. Only labs registered with the CDC to work with SARS — as Baric's is — will be able to order a complete synthetic copy of the new coronavirus.

  • But the consortium only represents 80% of the global DNA synthesis market.

My thought bubble: Synthesizing viruses from scratch still requires considerable resources and skill. But as that changes, synthetic biology will present a troubling dual-use dilemma — the same tools that could help counter an outbreak could be employed to create one.

USAID chief tests positive for coronavirus

The acting administrator of the United States Agency for International Development informed senior staff Wednesday he has tested positive for coronavirus, two sources familiar with the call tell Axios.

Why it matters: John Barsa, who staffers say rarely wears a mask in their office, is the latest in a series of senior administration officials to contract the virus. His positive diagnosis comes amid broader turmoil at the agency following the election.

COVID-19 shows a bright future for vaccines

Promising results from COVID-19 vaccine trials offer hope not just that the pandemic could be ended sooner than expected, but that medicine itself may have a powerful new weapon.

Why it matters: Vaccines are, in the words of one expert, "the single most life-saving innovation ever," but progress had slowed in recent years. New gene-based technology that sped the arrival of the COVID vaccine will boost the overall field, and could even extend to mass killers like cancer.

Beware a Thanksgiving mirage

Don't be surprised if COVID metrics plunge over the next few days, only to spike next week.

Why it matters: The COVID Tracking Project warns of a "double-weekend pattern" on Thanksgiving — where the usual weekend backlog of data is tacked on to a holiday.
