MitoTracker transfers from astrocytes to neurons independently of mitochondria The neuroprotective transfer of mitochondria from astrocytes to neurons has been primarily investigated by labelling astrocytic mitochondria with the dye MitoTracker. Here we report that MitoTracker transfers to neurons from both astrocytes and astrocyte-conditioned media, independently of mitochondrial transfer. Our observations should prompt an essential re-evaluation of the literature concerning astrocyte-neuron mitochondrial transfer and in other systems in which contact-independent transfer has been observed using mitochondrial dyes. ### Competing Interest Statement The authors have declared no competing interest.

The new open access policy of NIH will take effect next week (July 1st). All NIH funded research 🔬🧪🧬accepted after July 1st must be open access upon publication. Worried about fees? 💸 Check out how IAI stacks up against other journals—you might be surprised. #OpenAccess #SciComm #Microbiology

I like to bring #MicrobialCentrism swag to #ASMicrobe. I ask folks to post about their swag on social media. Some do, some do not. But right here, proof that a #QualityQuorum exists around me. Thank you, Seema Mattoo and Irene Newton. @mattoolab.bsky.social @chicascientifica.bsky.social

Proud of Rahul Saproo, undergrad researcher in my lab, who presented his work on Fic-mediated GMPylation at the @asbmb.bsky.social Annual Meeting! Thx to @hypothesisfund.bsky.social for funding this work.

‘One of the darkest days’: NIH purges agency leadership amid mass layoffs In shock move, four institute directors at the US biomedical agency are removed from their posts.

Director of the Nat'l Institute of Child Health and Human Development (NICHD) was summarily dismissed yesterday. So here's your reminder that birth defects kill twice as many American kids as cancer. But there is no St. Jude's for birth defects. Only the NICHD.

Energy from air? No problem! In our new preprint, we reconstitute the machinery that allows microbes to endure starvation. By using the trace amounts of hydrogen in air alone, they produce plenty of chemical energy (2 ATP) to get by. The only byproduct? Water. www.biorxiv.org/content/10.1...

Thanks to your earlier teaser, was waiting for this - simply beautiful! Truly delineating the building blocks of an otherwise complex system. What a great paper to cover in Immunology class/journal club! Love the analogy with Picasso’s drawing too. Congratulations to all of you!

What do Pablo Picasso and Charles Janeway have in common? Both were interested in patterns of life. Janeway was focused on pathogen associated molecular patterns (PAMPs) that are detected by our immune system. But what are these patterns he refers to?
