Happy to announce the publication using advanced models to understand how T cells mediate efficient immunoediting in early sarcomas.

This was a collaboration between Julie Cheung and Brian Hunt
in the lab

Thanks to Cancer Cell for publishing our work.

Distinct T cell functions enable efficient immunoediting and prevent tumor emergence of developing sarcomas
Cheung et al. describe efficient T cell control of nascent neoantigen+ and nearby neoantigen-negative sarcoma cells, underlying a ∼50% reduction in tumor penetrance. This otherwise imperceptible immun...

NEW: In an unprecedented move, the NIH will soon disinvite dozens of scientists about to take positions on advisory councils that make final decisions on grant funding.

NIH staff were told to select others aligned with the Trump administration and told to expect placements by political appointees.
Exclusive: NIH to dismiss dozens of grant reviewers to align with Trump priorities
The move would undo years of work, leaving advisory councils understaffed, and without the full expertise needed for reviews.

"No vaccine was tested more extensively than the RNA vaccines, and no vaccine was given to more people than the mRNA vaccines, & they were found to be incredibly safe...and effective. They saved 20 million lives, & they stopped a pandemic that was shutting down the world."

The problem with believing vaccines are dangerous is that by the time you realize you’re wrong, it’s too late and someone you love dies of a preventable disease.

Florida is about to find this out the hard way.
Florida's decision will cost lives.

RFK Jr. rolled out that old chestnut again about how healthy Americans were in the 60’s, so here’s a fact check.

In 1965:

-42% of American adults smoked; it’s 11% now.

-The infant morality rate was 24.7/1000; it’s 5.6/1000 now.

-Overall life expectancy was 70 years; it's about 77 years now.

A bizarre dogma has emerged among the anti-mRNA crowd that the only data we have on vaccines is from the original trial papers, rather than the HUGE volume of studies that came out subsequently...
... then an avalanche showing effectiveness vs hospitalisation, vs critical care, vs death, for subgroups, different variants, different vaccines, over time. These are UK only - knock yourself out.

That first study was just designed to check it worked safely vs cases.

To have this paper appear the same day that RFK Jr is canceling all mRNA vaccine funding is further indication that irony is not dead, even though we might all be soon.

BIG NEWS:

“Senate appropriators on Thursday approved an FY26 Labor-HHS bill that included a slight bump in funding for the NIH, with a strong 26–3 bipartisan vote.”

Thank you to members of the Senate Appropriations Committee on both sides of the aisle!

The NIH budget will INCREASE by $400 million — not slashed by 40%, as Trump proposed — according to a proposal by Senate appropriators, says Sen Murray.

"Some have asked if there will even be an NIH by [2029]. The commmittee's resounding message is yes—Congress has your back", she says.

Extra kudos and thanks to all the staff at NIH and NSF and other federal funding agencies for working extra hard in very small windows of opportunity to get grants reviewed and funds released before the attention-addled federal policies change again (on an hourly basis).
