Necroptosis in both tumour and stromal compartments determines responsiveness to immunogenic cell death-based immunotherapy - Nature Communications Most advanced triple-negative breast cancers remain resistant to immunotherapy. Here, the authors discover that RIPK1-driven necroptosis in both tumor and stromal compartments is essential for effecti...

Our new study is out in Nature Communications.
Using TNBC organoid mouse models, we show that necroptosis in both tumour and stromal compartments cooperatively drives effective responses to immunogenic cell death–based immunotherapy.

A Lab-stageΒ mRNA Vaccine Targeting Ticks May Offer Protection Against Lyme and Other Tick-borne Diseases A new laboratory-stage mRNA vaccine that teaches the immune system to recognize the saliva from tick bites could prevent these bugs from feeding on and transmitting tick-borne diseases to people, acco...

There are no vaccines to prevent alpha-gal syndrome currently.
Researchers are also exploring broader strategies i.e
vaccines targeting tick saliva proteins that could potentially block transmission of multiple tick-borne pathogens at once.

Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Played a small part in this cool study @jem.org.

Identifies myofibroblasts as sources of tissue damaging enzymes (MMP1) in TB granuloma, probably responding to cytokine cues from nearby macrophages.

Question now is: can we target therapeutically to prevent post-TB lung damage?

After Trump Officials Cut Food Aid to Kenya, Children Starved to Death β€œBrutal and traumatizing”: Interviews and a trove of internal documents show government officials and aid workers desperately tried to warn Trump advisers about impending disaster and death.

Secretary Marco Rubio claimed no one died as a result of cuts to USAID. That’s not what we found.

After Trump officials cut food aid to Kenya, children starved to death in an American-made hunger crisis.

They chose Trypanosoma crassii specifically because:
1) it's related to two human parasites - T. brucei (sleeping sickness) and T. cruzi (Chaga disease).
2) Because it can infect zebra fish larvae, its behaviour can be observed in situ through the fish's body πŸ§ͺ

One of my favourite papers about Trypanosoma parasites is this study where researchers infect zebra fish larvae (which are transparent) with Trypanosoma carassii and were able to observe how these single-celled parasites move through their host's body. πŸ§ͺ

Dunkleosteus terrelli (Newberry, 1873) - fossil fish skull (real) from the Devonian of Ohio, USA. (public display, Cleveland Museum of Natural History, Cleveland, Ohio, USA)

The placoderms are a group of extinct, mostly predatory fish that existed during the Middle Paleozoic (Silurian and Devonian). The most famous placoderm was Dunkleosteus, which was named after David Dunkle, an Ohio paleontologist. It was not a shark - it had a bony skull, a neck joint, and remarkably, the jaws lacked true teeth. Instead, the jawbones were sharp-edged and pointed.

The Late Devonian (~380 MYA) was an era dominated by armored fish like Dunkleosteus terrelli here. They were primarily cartilaginous, like the sharks they hunted, but covered by armor plates up to 3 in. (7.6 cm) thick.

They were also among the first animals to give live birth.

People seem to forget this is how it starts, not how it ends. There's a lot that happens and, as history notes, oftentimes goes sideways between here and there.

Measles outbreaks are costing the U.S. millions of dollars. The true losses can't be counted. As vaccination rates decline, the economic consequences will increase, research suggests.

The first concern with measles is, of course, the devastating health impact.

But this article does a great job of explaining the economic costs.
