Hank Seifert is a Professor at Northwestern Medical School in Chicago. I'm interested in everything, particularly bacteria, but our group studies the Neisseria gonorrhoeae pilus—antigenic variation and functions.

It is absolutely wild that the guy who won’t stop yelling about law and order is now personally stepping in to keep January 6 documents hidden from the police officers who were attacked that day. He knows exactly what’s in those files and he is terrified the country will see it.

Iryna Boiko and Selma Mettane show that most gonococcal genomic sequences are from nonpiliated bacteria, even though clinical isolates are piliated.

The right-wing think tank which wrote the entire platform for the current president of the US is defending neo-Nazis, and meanwhile a substantial portion of American rabbis think the Muslim candidate for NYC mayor who has denounced antisemitism is the biggest threat to me as an American Jew.

If one of the appliances in your home, say your cooker or fridge, ran using ten times the power of a normal one, you‘d replace it as fast as possible and never go near that manufacturer again, because you’d think they were catastrophically bad at making stuff.

But it’d be cool if it talked, right?

The NIH ordered me to stop my ‘dangerous’ gain-of-function research. It isn’t dangerous at all Safe gain-of-function research is necessary to identify new treatments for diseases like for tuberculosis — but the NIH has imposed unfounded stops.

Our latest efforts to understand Enterococcal wound infection. In long-term collaboration with @gthibault.bsky.social, we discovered how E. faecalis makes extracellular ROS - via EET!⚡️Which in turn dysregulates host UPR to delay wound healing.
