How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy

Thank you Dr. DiMaggio for sharing your frontline experiences as a pediatrician treating children dying from diseases that we seldom see now because of vaccines

Gave some quotes to NPR about the coming chaos with the DGAs.

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Why don't we have more good journalism?

Mostly, because people are unwilling to pay for it.

We have, collectively, gotten the idea that information should be free for the reading.

You can't complain about lousy reporting & analysis and also gripe about paywalls.

URGENT! Today the pedal hits the metal. Democrats have to play hardball to protect public health, healthcare and science. Write to your Senators and Representatives and share this post! actionnetwork.org/letters/tell...

Breaking down the folate/leucovorin/ASD story here:

This is an important one for the media to get right & pressure HHS to fund $$ solid trials. The energy of this moment could really get citizens and caregivers/pts involved in the scientific process.

No, glucose monitors aren't particularly helpful for people who don't have diabetes or pre-diabetes.

Pathologizing insulin spikes is yet another distraction from the reality of an untenable food environment.

It's still a little bewildering to me that the same folks pushing designer vitamins with methylated folates also emphasize methyl B12, despite evidence of upper axial ligand removal from any B12 you consume & that the cobalamin is accepting the methyl group from folate b4 transfer to homocysteine.

Teamwork with the Anna Thalacker-Mercer lab and some of my favorite co-authors. A B12-deficient diet negatively impacts mtDNA integrity and mitochondrial function. Excitingly, B12 supplementation improves complex IV activity in aged mice.

Thanks to some of my favorite co-authors Luisa Fernanda Castillo, Katarina Heyden, and Caitlyn Pelletier! If you are interested in how mitochondrial and nuclear DNA are affected by folate and B12 availability, don't miss this one. Spoiler: the mitochondrial DNA might hold the key!

What an amazing time to be a biomedical scientist.

Thank you to the @cornelluniversity.bsky.social Chronicle for highlighting our work and the impact of the stop-work order!

The grey skies did not stop us from celebrating Dr. Castillo and all her accomplishments this weekend! Once again so proud of my group.

Important message. Also important to remember that federal funding for science isn’t “given” to university laboratories - it is awarded based on highly competitive process, profs spend months/years on proposals that are reviewed by experts, most are rejected.

Adding insult to injury, those loudest abt the supposed harms of things like seed oils in infant formulas never advocate for policies that can help support increased breastfeeding, like paid family leave, increasing access to lactation consultants, public campaigns to destigmatize breastfeeding, etc

Giving a Continuing Education webinar tomorrow on fiber for any RDs interested! I'll be taking a historical approach covering fiber's complex chemistry, evolving definitions, analytical methods and current evidence/recommendations - still time to register!

What if MAHA could do something really good for America? @kcklatt.bsky.social has an idea that would help the wellness-focused movement actually evolve: fund clinical nutrition studies.

Kevin joins me on the last episode of S1 of Clarity Lab this week.
