Rowan Walrath @rowanwalrath.bsky.social · 18/09/2026Heads up: I'll be away the weeks of 9/21 and 9/28. I trust that my sharp C&EN colleagues will capably handle anything that comes up in my absence. I return 10/5, so if you need something from me specifically, I'd reach out or re-up then! 001
Rowan Walrath @rowanwalrath.bsky.social · 01/09/2026The coolest part, IMO, is this "build your own city ranking" tool. You can use sliders to adjust how much weight you'd give to one dimension, like VC funding or lab space, and see what cities come out on top. 102
Rowan Walrath @rowanwalrath.bsky.social · 01/09/2026Boston & Massachusetts may not house the headquarters of top US pharmaceutical companies, but they commands the most chemistry-related VC investment and the third-highest chemistry article output, reflecting their status as a life sciences hub spanning start-ups, academia, and research hospitals. 100

Rowan Walrath @rowanwalrath.bsky.social · 20/07/2026Precision-medicine approaches show promise, but researchers need buy-in from drugmakers. And that buy-in is not really happening. 11/ 150
Rowan Walrath @rowanwalrath.bsky.social · 20/07/2026The trial would ultimately throw Delli Gatti into the unstable world of long COVID research and development, showing how a tangle of competing corporate and scientific priorities—and regulatory catch-22s—have hamstrung experimental treatments for postinfectious conditions. 5/ 161

Rowan Walrath @rowanwalrath.bsky.social · 05/03/2026The FDA recently described a new regulatory framework that would let personalized medicines with a “plausible mechanism” of action bypass randomized clinical trials. But recent decisions about rare disease drug applications raise doubts about what the pathway means for patients. #chemsky #biosky 133

Rowan Walrath @rowanwalrath.bsky.social · 08/09/2025It's no surprise to anyone who's been paying attention that China's biomedical engine is churning out more and more new molecules -- and innovative ones, not just "me-too" drug candidates. 🧵 #chemsky #biosky 131

Rowan Walrath @rowanwalrath.bsky.social · 14/03/2025@mileswgriffis.bsky.social wrote it best, in my opinion, in this recent essay for @thesicktimes.bsky.social chronicling half a decade of Long COVID. thesicktimes.org/2025/03/07/h... 1135

Rowan Walrath @rowanwalrath.bsky.social · 18/02/2025In my @cenmag.bsky.social story about RFK's confirmation -- written before the weekend HHS firings -- a former FDA leader points out that the Trump admin may actually end up shooting itself in the foot with these kinds of cuts. 152
Rowan Walrath @rowanwalrath.bsky.social · 21/11/2024About two-thirds of the drugs proposed as interventions were immunomodulatory agents. The top two were naltrexone (presumably low-dose naltrexone aka LDN) and monoclonal antibodies. 130
Rowan Walrath @rowanwalrath.bsky.social · 21/11/2024Most proposed interventions were drugs. No surprise there -- people with Long Covid have been clamoring for trials of pharmaceutical interventions (not exercise therapy, not CBT). 130
Rowan Walrath @rowanwalrath.bsky.social · 21/11/2024A few interesting takeaways from NIH's first RECOVER-TLC meeting about #LongCovid clinical trials since the 3-day workshop in September. More than 300 submissions to RECOVER-TLC's online portal. Overwhelmingly patients! 🧵 1147
