Screen capture of an online quiz result. A cartoon drawing shows a beige and turquoise colored capsule dressed like Clark Kent as he reveals his Superman outfit. In place of a Superman S there is a D. The text reads, “You are doxycycline! You are an under-rated talent who flies below the radar, and others often don't see your true potential. You find that people either really like you or simply don't know you exist. You're on the quiet side and wish people would get to know you more. You tend to not be as physically active as others and often stay indoors to avoid too much sun.
Did you know? Doxycycline is an antibiotic in the tetracycline class. It has activity against a range of bacteria and even some” [cut off]

Reminder it's also Trans Day of Having a Nice Snack, a low-$ way to materially celebrate trans folks beyond problematic visibility—search for lots of trans folks you can Venmo a couple $ to—& look for what you can do vs accelerating legal hate while you're at it. (Had my 🍟 last night so I'm good!)

Graphic from The Sick Times sharing the latest COVID-19 trends for February 3, 2026. The graphic presents trends for three metrics: WastewaterSCAN category for SARS-CoV-2, which is "high" (represented with an orange color) and reports a slight decrease (represented with a diagonal down arrow); CDC wastewater viral activity level for SARS-Cov-2, which is "moderate*" (orange) and reports a slight decrease; and CDC COVID-19 test positivity, which is moderate (darker yellow) and stable (side to side arrow). Text below these metrics reads: "*CDC wastewater viral activity levels are calculated based on measurements in the last two years only. They do not account for the lower spread that could be possible with more widespread precautions."

The middle text reads, “COVID-19 levels are going up in parts of the South, West, and possibly the Midwest, while continuing to decline elsewhere. Trends suggest we may be in for a second round of this winter’s COVID-19 wave after the initial peak in early January. Flu levels increased this week, too, likely due to more influenza B spread. — Betsy Ladyzhets.”

I remain a tremendous fan of @cp-cell.bsky.social and @cp-cellreports.bsky.social, where I spent 7+ exciting years reading immunology, vaccine and infectious disease work, and lots of other things. Big thanks for all I learned there and pride for all we accomplished together. 🤓🫶

The science behind gender-affirming care has been endorsed by every major medical organization. This isn't about science or medicine. It's about the discomfort many non-trans people feel over the *existence* of trans people.

Immunotherapy researcher Miriam Merad from Icahn Mount Sinai says the reason that cancer research has slowed is because of funding issues, which is something taxpayers don’t have to accept.

“We fight for patients, we fight for science, and we have to fight for progress.”

Just imagining how much better it would be if ALL news stories about vaccine-preventable illnesses were illustrated with pictures of people with the disease, not pictures of needle injections. If you must show something that people will find scary & unpleasant, make it the disease, not the cure.

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...
