“In any crisis, leaders have two equally important responsibilities: solve the immediate problem and keep it from happening again."

Indian scientists have discovered a previously unknown mechanism underlying life-threatening sepsis and proposed a new treatment strategy centered upon cell-free chromatin (cfCh), they reported in the March 4, 2020, edition of PLOS ONE.

COVID-19 has disrupted science in the way it has disrupted everything else. In the short term, universities have largely closed shop as a way to maximize social distancing, and lots of science – or at least, lots of bench work – is not getting done.

LONDON – Two papers published online in Nature following accelerated peer review provide fine detail of how the spike protein on the COVID-19 coronavirus binds to the angiotensin converting enzyme 2 (ACE2) through which it infects its human host.

Undetected cases were a major driver of the early spread of SARS-CoV-2 in Wuhan, China, despite being less infectious on a case-by-case basis, according to a modeling study published in the March 16, 2020, online issue of Science.

LONDON – Six weeks on from the initial alert, “the window of opportunity” to control the COVID-19 epidemic is “narrowing,” according to the latest assessment from WHO Director General Tedros Adhanom Ghebreyesus.

SEATTLE – Tracing the family tree of COVID-19 through its evolving DNA sequence makes it possible to disprove many false claims circulating on social media about the novel coronavirus, and, in particular, that it was generated in a covert biological weapons program. “From everything I’ve looked at, there is zero evidence for genetic engineering; it looks like normal evolution,” said Trevor Bedford, a computational biologist at Fred Hutchinson Cancer Research Center, who has been using genomes sequences taken from patient samples to track the spread of the virus since Jan. 11.

At this very early point in the emerging 2019-nCoV outbreak, knowledge about the virus is insufficient to predict what shape that outbreak will ultimately take.

The drug screens prompted by the SARS and MERS outbreaks have been useful for quickly identifying drug candidates. But in terms of their epidemiology, “SARS and MERS were different from this coronavirus,” Allison McGeer explained at a Feb. 3 webinar by Evercore ISI.
