Acetaminophen Use During Pregnancy and Children’s Risk of Autism, ADHD, and Intellectual Disability This nationwide cohort study with sibling control analysis examines the association of acetaminophen use during pregnancy with children’s risk of autism, ADHD, and intellectual disability.

Unrelated to anything, just a cool recent paper

Gut fungi are associated with human genetic variation and disease risk In contrast to decades of research on gut bacteria, human genetic determinants of the gut fungal community (mycobiome) remain understudied. This investigation presents the first GWAS on the number and...

Excellent journal club discussion today of a new paper finding human genetic variants associated with fungi in the gut - interesting results!

Rapid Response: Reinvesting in Racial and Indigenous Health Equity Research The purpose of this call for proposals is to meet the current moment by supporting timely, actionable health equity research that has been interrupted by shifts in federal funding.

More foundations should do this:

"Funding is exclusively available to applicants who have already received federal funding (e.g., from the NIH, CDC, NSF) for their health equity research, but have since had their funding rescinded due to federal administrative actions"

A defined microbial community reproduces attributes of fine flavour chocolate fermentation - Nature Microbiology An in-depth microbiological and metagenomic analysis of Colombian farm and fermentation facilities resulted in the design of a defined microbial community that can reproduce the flavour of fine chocol...

Cool application of microbiome in food science

Using metagenomics on Colombian cacao, they mapped how microbes influence chocolate flavors. Then they built a defined microbial consortium that replicates premium chocolate flavors -- validated by trained tasters!

That's great. But it's likely that this competition ended and funds were committed before their apparent shift in priorities

This is not just HHMI. All Chan Zuckerberg Initiative funding calls are CLOSED. The Gates Foundation has no Grand Challenges funding opportunities. I've never seen anything like this. Private foundations have just decided to stop supporting biomedical research.

Fascinating new paper reveals a new gut microbiome connection to heart disease. Microbes produce imidazole propionate (ImP), which directly triggers atherosclerosis through immune activation - even without high cholesterol.

New paper showing that gut bacteria absorb "forever chemicals" (PFAS) at high levels.

This bacterial "sponge effect" could influence PFAS levels in our bodies and explain individual differences in PFAS exposure.
