Expansion of genital Tregs reduces neutrophil influx and maintains mucosal barrier integrity during inflammatory bacteria challenge Inflammation in the female genital tract (FGT) is central to the initiation of an effective host immune response against pathogens that are transmitted across this surface. However, if dysregulated, i...

Wanted to highlight our latest preprint--a huge effort by multiple people and labs, but led primarily by @wsdewitt.github.io, Tatsuya Araki, and Ashni Vora, in a very close wet-dry collaboration with @matsen.bsky.social’s lab at the Hutch

Opinion | Here are the people Trump doesn’t want to exist Women, people of color and those in the LGBTQ+ community are main targets.

When Trump encounters a demographic he doesn’t care for, he “disappears” them–in many cases, the very record of their existence.
Meet America’s new “missing persons," and the govt campaign to delete statistical evidence of anyone who doesn't fit Trump’s idea of our new golden age.

"And the best thing about the polio vaccine is that it even protects people who don't believe in it."

What am I supposed to say to this generation of young scientists? Undermining the future of American science is not a path to accountability — it’s a path to decline.

'At the institute I lead, almost all of the canceled grants were ones specifically awarded to support the training of young scientists. Each of these young scientists represents the future of American science: the next innovators, mentors, and developers of lifesaving treatments.'

Excited to announce our newest #Immunology recruitment 🎉🥳

With its anti-science and anti-public health policies, the US is now at risk for outbreaks of tuberculosis

As @johngreensbluesky.bsky.social put it, "TB is both a form and expression of injustice"

Now more than ever.

Headed into the weekend, a gentle reminder that this whirlwind is specifically designed to make us feel exhausted, overwhelmed, resigned, & sapped of energy, and that it is more important now than ever to connect with your community. Hug your family, check on your friends, walk in your neighborhood.

Scientific institutions have a long history of anticipatory obedience Societies should learn from this and speak up to support inclusion

I have run out of patience with the apparent silence of most US science institutions (and not just US) in the face of Trump & Musk's rampage. There are of so many facets of that, but in this column for @chemistryworld.com I talk about the assaults on inclusion.

Opinion | DEI and Disparate Impact The next step in restoring meritocracy is to reject the theory that proportionate outcomes equal fairness.

this is the "merit" two-step. first, you strongly imply or state outright that the presence of anyone who isn't a straight, able-bodied white man is unfair "DEI," then you argue that just because an institution is all-male and lily-white doesn't mean there is discrimination. that's just merit!

Nobel laureates call on National Academies and biotech CEOs to speak out against Trump attacks on science Nobel laureates are calling on the National Academies and biotech CEOs to speak out against what they see as the Trump administration's attack on science.

"Nobel laureates call on National Academies and biotech CEOs to speak out against Trump attacks on science"

The societies, academies, and other leaders have been MIA for years, leaving it to individual scientists to pick up the slack.

Maybe time to step up?

The NIH Office of Research on Women’s Health was created in 1990.

Women’s health issues didn’t exist before then.

(actually most people just didn’t care)

I’m sure the website is down because we’ve solved all those problems. /s

Congrats Dr Santer!

NIH is a massive job creator (412041+).

Non-defense spending such as NIH yields SIGNIFICANTLY higher return on investment than defense spending.

In Michigan alone, $991M of NIH funding creates $2420M of economic activity, a 244% return on investment.

NIH funded research benefits your community even if it doesn’t (yet!) directly benefit you. Each $ invested in NIH yields significantly higher return on investment (average 254%) than the same $ invested in “defense”.

To end AIDS, states must ensure that everyone can access treatment without fear.

Around the world🌎, well organised attacks on rights are surging. This is especially harmful to people living with and at risk of HIV, who are made afraid to seek lifesaving services. ​

To #endAIDS, we must take the RIGHTS path.

Excited to join the BlueSky science community and continue to share my journey as a future mucosal immunologist! ☁️

I am currently wrapping up my PhD at the University of Manitoba in Canada under the supervision of Dr. Thomas Murooka :)

Hi! I would love to be included - thanks :)
