Very happy to share our new paper. Together with our wonderful collaborators, we found that L-2-HG, a metabolite often viewed as “toxic,” also has an essential physiological function in mice. www.nature.com/articles/s41...

Our paper is now out in Science! Super excited to share our discovery that #mitochondria #pearling is the elusive mechanism driving the regular distribution and inheritance of #mtDNA nucleoids 🧬 [1/6]

I have to share this, it’s just too funny/egregious.

Thanks @mitodynamics.bsky.social for the fun interview and for saying it like it is: “…JCS and other community journals are being crushed by the mega profit-making journals, which just seem to proliferate and spit out new journals by the day…we must all make an effort to move away from this…”

Non-profit journals are on the critical list. The cause: academics obsession with the Nature brand, coupled with the APC $ model. Some will argue it doesn’t matter (“all as bad as each other”). But the fact is undeniable and it’s good guys who put money back into science like COB who are losing..

Looks like a cool study.

With #NKH, severity is tricky to predict, and can’t be predicted from birth/initial presentation. Some children don’t reach milestones past that of a newborn. It's heartbreaking. May 2nd is #NKHAwarenessDay - please donations for a cure: www.justgiving.com/page/nkhawar... #glycineencephalopathy

Nonketotic Hyperglycinemia (NKH) is a rare disorder in children, where they can't process glycine. It's is a brutal disorder. May 2nd is #NKHAwarenessDay - swap your coffee for a donation towards NKH Research: justgiving.com/page/nkhawarenessday2025 ⁣ #nkhawareness #nonketoticHyperglycinemia #NKH

Interesting for those working on nonketotic hyperglycinemia.

Propionic Acidemia is an inborn error of metabolism. It is a rare genetic disease that is included in newborn screening programs around the world. Individuals with propionic acidemia need improved treatment and a cure.
