In this special Covid-19 edition of The Florentine, rejoice in a renewed humanism from Florence, of learning, words, thoughts and creativity, with articles, poems and short stories penned by the city’s international community, plus ideas and considerations for the future from Tuscany’s leaders and institutional figures, all interspersed with iconic photography of Florence at its most restful.
From a The Guardian article (April 9, 2020):
A hundred days after a Chinese government website announced the discovery of a “pneumonia of unknown cause”, it has become clearer that the dynamics behind the virus’s rapid expansion across the globe has relied heavily on such “cluster effects”.
Each of the countries most heavily hit by the pandemic has reported similar stories of social, cultural or religious gatherings where large numbers spent numerous hours in close company – holding hands, kissing, sharing drinks from the same glass – which then turbo-charged the spread of the pandemic.
“Most infections didn’t take place in supermarkets or restaurants,” Streeck said of his preliminary findings. In Heinsberg, his team of coronavirus detectives could find scant evidence of the virus being transmitted via the surfaces of door handles, smart phones or other objects.
This week, a new enzyme speeds up the breakdown of plastic bottles, and a method to cool molecules to a fraction above absolute zero.In this episode:
01:18 A PET recycling enzyme
Researchers have engineered an enzyme that effectively breaks down the plastic PET into its constituent monomers. This could allow for more complete recycling of bottles and clothes. Research Article: Tournier et al.

The shocking lengths humans will go to to satisfy their curiosity, and the reasons for elevated methane emissions at Oktoberfest. Research Highlight: Humans opt to brave electric shock to satisfy their curiosity; Research Highlight: Munich’s Oktoberfest is a real gas
09:15 Supercool molecules
Researchers have used a technique called ‘collision cooling’ to chill molecules to a few millionths of a degree above absolute zero, which could allow observations of difficult-to-study quantum mechanics. Research Article: Son et al.

An interview with Dr. Anthony Fauci about what it will take to open America back up after the coronavirus pandemic: “It isn’t like a light switch, on and off.”
NPR’s Tamara Keith and Amy Walter of the Cook Political Report join Lisa Desjardins to discuss the latest political news, including the fallout from postponing so many 2020 primary elections, a phone call between President Trump and former Vice President Joe Biden about coronavirus response and the fallout from Trump’s firing of the intelligence community inspector general.
Rupert Beale talks again to Thomas Jones about his work at the Francis Crick Institute, where he’s helping to set up a testing lab for Covid-19.He talks about the challenges of creating a scalable process, explains why a successful antibody test could be hard to achieve, and finds some reasons to be hopeful.

A selection of three essential articles read aloud from the latest issue of The Economist. This week, covid-19 presents grim choices between life, death and, ultimately, the economy (11:02), lockdowns in Asia have sparked a stampede home (17:52) And, Formula 1 comes up with a breathing machine for covid-19 patients.
Conclusion: The study was inconclusive with respect to potential differences in progression of individual radiographic features after surgical and non-surgical treatment for degenerative meniscal tear. Further, we found no strong evidence in support of differences in development of incident radiographic knee osteoarthritis or patient-reported outcomes between exercise therapy and arthroscopic partial meniscectomy.
Objective: To evaluate progression of individual radiographic features 5 years following exercise therapy or arthroscopic partial meniscectomy as treatment for degenerative meniscal tear.
Design: Randomized controlled trial including 140 adults, aged 35-60 years, with a magnetic resonance image verified degenerative meniscal tear, and 96% without definite radiographic knee osteoarthritis. Participants were randomized to either 12-weeks of supervised exercise therapy or arthroscopic partial meniscectomy. The primary outcome was between-group difference in progression of tibiofemoral joint space narrowing and marginal osteophytes at 5 years, assessed semi-quantitatively by the OARSI atlas. Secondary outcomes included incidence of radiographic knee osteoarthritis and symptomatic knee osteoarthritis, medial tibiofemoral fixed joint space width (quantitatively assessed), and patient-reported outcome measures. Statistical analyses were performed using a full analysis set. Per protocol and as treated analysis were also performed.
Results: The risk ratios (95% CI) for progression of semi-quantitatively assessed joint space narrowing and medial and lateral osteophytes for the surgery group were 0.89 (0.55-1.44), 1.15 (0.79-1.68) and 0.77 (0.42-1.42), respectively, compared to the exercise therapy group. In secondary outcomes (full-set analysis) no statistically significant between-group differences were found.
Syndicated columnist Mark Shields and New York Times columnist David Brooks join Judy Woodruff to discuss the latest news, including how the coronavirus pandemic has taken hold in the U.S., American leadership amid the crisis, whether the $2.2 trillion stimulus package will help those besieged by the pandemic and whether there is a chance for bipartisan political action.
Food and medicine shopping is essential during the COVID-19 pandemic, but requires getting out and standing close to strangers at a time when social distancing and sheltering-in-place are recommended to slow spread of disease.
David Aronoff, MD, director of the Division of Infectious Diseases at Vanderbilt University in Nashville, explains how to minimize COVID-19 risk while shopping.
