Tim Curry, a character actor who created a gallery of delicious, very loony villains for stage and screen, including Dr. Frank-N-Furter in "The Rocky Horror Picture Show," has died. He was 80. https://to.pbs.org/4y2twIM

4/ What if the key to understanding bacterial stress response is in their electrons⚡? Awardee @copperbae.bsky.social is tracking electron balance as a novel way to predict how well a bacteria's defenses are holding up. 🍾 Congrats Dr. Johnson! @uarizona.bsky.social 🙏 #HFScout @drkhaynes.bsky.social

2/ Meet Awardee Noah Palm. He’s setting out to uncover how the gut microbiome & immune system have co-evolved--he thinks that antibodies aren’t just for defense but are actively shaping the evolution of our commensal gut microbes 🦠. 🥳 Congrats Dr. Palm! @yale.edu 🙏 #HFScout @victora.bsky.social

Want to hear something freaky? If a deer gets a cut on its antlers while it's still in velvet, the next year when the deer grows a completely NEW rack, it will often grow an extra branch in the exact spot of the cut. Let's talk about TROPHIC MEMORY, the weird way cells (may) remember each other.

New insights into copper physiology in Bacillus subtilis. The outlines of the pathway for copper import and trafficking to support aerobic growth are emerging. Work led by Grayson Barnes, with support from our collaborators. doi.org/10.1128/mbio... #microsky #metalsinbiology

doi.orgPathways of copper import and utilization that support respiration in Bacillus subtilis | mBioCopper is a critical micronutrient for bacteria; however, it is toxic in excess. This leads to the cell having tightly regulated import and export systems to prevent intoxication while having sufficient copper for cellular needs. Copper export has been well studied, but copper import and the effects of copper starvation are less defined. In this article, we characterize the Bacillus subtilis high-affinity copper importer YcnJ. We show that under copper limitation, the cell is deficient in copper-containing oxidases, which leads to respiratory defects. Copper imported by YcnJ is proposed to function in a pathway with other proteins implicated in the assembly of respiratory oxidases. More generally, this work contributes to the underexplored area of copper import and trafficking in bacteria.
