U.S. plans to stop recommending most childhood vaccines, defer to doctors
The plan, which is not finalized, suggests children get fewer shots and shifts to a model telling parents to consult doctors to make their own vaccine choices.

She let me know that they recently received guidance that, ONLY for the January EI deadline (1/27/2026) and the February ESI deadline (2/3/2026), PIs can submit MIRAs even if their previous application (R35, R01, R15, R21, and R37) is still considered under review.

How are people dealing with AI use in their grad programs, specifically for thesis proposal, qualifying exam, dissertation? Banned completely? Allowed, but have to recognize its use? No guardrails at all? We have to develop a policy and I’m totally at a loss.

American Academy of Pediatrics loses HHS funding after criticizing RFK Jr.
HHS cuts key AAP grants, citing concerns about “identity-based language” and insufficient focus on agency priorities. The organization said the cuts could harm child health.

who has favorite ways to measure hypoxia in tissues using immunofluorescence/microscopy?
i guess maybe the gold standard is pimonidazole/hypoxyprobe- is there any reliable way that doesn't involve injecting anything in vivo? (like what do people do for human tissues?)

Totally fascinating results from @krishnanyamuna.bsky.social and coworkers on pH gradients *within individual cellular compartments*, upending dogma — read this thread! 👇
Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

Carefully.
At high spatial resolution.
Across many organelles. 7/n

Participants emerge from the conference room into the bright sunlight of Naoshima Island in CCII's first international symposium on Cancer, Metabolism, and Immunity.
CCII sponsored this small, intimate meeting where participants freely shared and discussed ideas & data in a beautiful setting.
