My darling son Adam would have been 43 today. Cherishing memories of hanging out with him—here in 2012. ❤️

In February 2021, a town in Brazil showed up for a groundbreaking randomized Covid vax trial, providing evidence of population effects of mass vaccination in a pandemic. My latest @plos.org post digs into this exciting precedent & why it matters: absolutelymaybe.plos.org/2026/03/28/a...

Adjusting to the Changing Internet When ads flooded some parts of the internet, I adjusted by avoiding those places when I recognized the signs—or hitting the back button quickly when I hadn't. When "AI" scrapers led to an explosion of sites making me wait while checking if I'm a robot, I got used…

Really good blog posting from @hildabast.bsky.social on some of the most recent trends in #PeerReview, headlines topics in her 🦋 Skeet 👇

This photo is from camping a few years back—one of the major out-of-control fires in our area is burning there. 😢 We're into day 2 of >40 C (100 F), in catastrophic fire risk for another day at least. Ready to evacuate if the wind turns in our direction. 😬

“Blogging in the Ruins”—Some Counterpoints As of this month, I've been blogging—with words and cartoons—for 14 years. My enthusiasm for it has waned at times, but it always comes back. So when Joan Westerberg posted The Case for Blogging in the Ruins, I clicked quickly. And I anticipated being…

Good piece.

This was a light-bulb moment for me! My new post @plos.org comes from learning about the concept of science populists: absolutelymaybe.plos.org/2025/12/19/s... ....

New study from IQWiG: You can do without searching Embase for drug studies – though that could change if something drastic happened to PubMed. (Currently only in German.) #MedLibs

This Was a Strong Way to Respond to Science Criticism A vaccine that can prevent cervical cancer is frankly awesome. Cervical cancer is dreadful, and the lengths we go to in treating lesions that could develop into the disease cause misery to millions. Yet, HPV vaccines have always been a magnet…

We've had to wait a long time to get to this point! With this new pair of Cochrane systematic reviews, the weight of the evidence has tipped very heavily in favor of HPV vaccination. My new post @plos.org absolutelymaybe.plos.org/2025/11/24/t... #Vaccines

OLSPub, the plan for a PubMed safety net, is going to need governance & funding support beyond Germany. DFG, a national German research funder, * might * support some of it, but not enough. @zbmed.bsky.social will now be fast-tracking their plans for a distributed European network. ...1/2

A Bumper Month for Covid Vaccines and More It's been an eventful few weeks for Covid vaccines – mostly good, some very bad. Let's start with the good news. Novavax has transferred marketing of its protein subunit Covid vaccine in the EU and US to a major pharmaceutical company, Sanofi. Here's…

Oh my! I didn't realize the Australian CDC already has a website: cdc.gov.au 🎉 It's technically the interim CDC, as it's only due in January 2026 (if all goes to plan). www.cdc.gov.au/about/about-...

PubMed had some disruption in adding records this week, apparently recovering on Wednesday with over 9,800 records in one day. But if you have a Plan B for critical searches, maybe start using it... 1/2 Chart data: New daily records 2024/25. Some dip on weekends is normal. bit.ly/42MfAFM #MedLibs

Tracking Shutdown Impact and Changes at PubMed There's been some panic about PubMed again, since a notice on the website warned it could be out of date because of the US government shutdown. Shutdown is dreadful, in so many ways. But that notice doesn't mean PubMed has been de-funded, or that it's…
