theconversation.com/the-peer-revie… Some interesting things to consider. I have to agree that peer review does not always guarantee quality…

Memorable question
@wabipconnect #Bali2024 #Pleural Session: Q&A with me + Prof Astoul (pleuroscopy guru):
Audience: Prof Astoul what's your best strategy for intercostal hemorrhage from pleuroscopy bx?
Prof: Don't know. Never had one; I'm always careful. Ask Gary Lee...

Update - now 3 of my study clinicians are unable to go to the Union meeting in Paris this week. 2 with oral presentations. So disappointing for all concerned. Not to mention expensive and time consuming since applications could only be made in Dakar, a 10h drive from here...

@Sutherland_TB @hannah_rickman @EDCTP @TriageTB I’m never sure whether or not to hit “like” on things like this. It’s great that you tweeted and that people can see this happened and how unfair it is. I obviously don’t “like” this situation. So so unfair. [All conferences in Kenya from now on?]

Traditional cultures for diagnosing infection are limited by sensitivity & can require days to give results. The CHEST #Sepsis Resources Steering Committee outlines newer molecular methods that may be able to identify pathogens & drug resistance sooner: hubs.la/Q01YnMv10

Low airway surface pH impairs antimicrobial host defence and worsens airway inflammation. A novel, inhaled, alkaline buffer medication, Optate, raises airway pH and inhibits RSV infection in primary human airway epithelial cells in a dose-dependent manner. bit.ly/4138MAM

A mind-blowing paper has come out today in @Nature
In 2016, JC Venter Institute scientists trimmed a bacterial genome to its barest minimum required for life to synthesize what they called a "minimal genome" (science.org/doi/10.1126/sc…).
Today, a group of scientists from Indiana University reports how that minimal genome evolved over 2000 generations in comparison to the non-minimal genome.
The authors found that even when you reduce a bacterial genome to its absolute minimum where every nucleotide matters, the genome undergoes mutational events generation after generation as much as the non-minimal genome. One simply cannot stop the evolution.
Just over 300 days of evolution (equivalent to 40,000 years in humans) the minimal cell has gained everything it lacked in fitness on day one in comparison to the non-minimal cell.
When comparing the evolved traits between the minimal and non-minimal cells, the scientists found something striking. The evolutionary process increased the cell size of non-minimal cells but not that of the minimal cell. But that is not the striking part.
The scientists were able to identify the key mutation that resulted in cell size evolution. And it turned out that the mutation that helped the non-minimal cells to grow bigger is the same that helped the minimal cells to stay smaller. Growing bigger had a survival advantage for non-minimal cells and not growing bigger had a survival advantage for minimal cells. So, the mutation had a context-dependent effect. This just demonstrates that the evolutionary effects on traits have no absolute direction. All that matter is what is beneficial for the organism's survival.
The conclusion of the paper is metaphorically a quote from the Jurassic Park movie:
“Listen, if there’s one thing the history of evolution has taught us is that life will not be contained. Life breaks free. It expands to new territories, and it crashes through barriers painfully, maybe even dangerously, but . . . life finds a way". (scienmag.com/artificial-cel…)
