Congratulations to #KarenArndt #UniversityOfPittsburgh presenting the #Yeast26 Lee Hartwell lecture and sharing the journey from #RTF1 to the #PafComplex (#Paf1C) (leaving me scrambling to learn about #AnchorAway). @genetics-gsa.bsky.social
Woman with short brown hair wearing black sleeveless dress is standing at a podium to the right of a giant white slide. The top left corner has an image labeled Dr. Leland Hartwell, and the image shows a black and white headshot of a man with grey/white hair wearing a white shirt and black tie. The middle of the slide shows a yellow box with text: From the 2001 Nobel Lecture by Leland Hartwell: “My research career has been motivated by a desire to understand cancer. Each time I have identified an intriguing aspect of the cancer problem, I have found that it could be approached more effectively in the simpler eukaryotic cell Saccharomyces cerevisiae, than the human cell. Each time the yeast cell has revealed some of its secrets.”

A single-cell atlas of Toxoplasma sexual development in the feline intestinal tract
Nature Microbiology, Published online: 22 April 2026; doi:10.1038/s41564-026-02294-7Single-cell RNA sequencing is used to study the sexual development of Toxoplasma gondii in cats, generating a transcriptional atlas and showing that the female-specific gene AP2X6 functions as a regulator of oocyst formation.

Method distinguishes TB from nonpathogenic relatives and enables live-cell imaging, great promise toward diagnostics
New molecular label could lead to simpler, faster tuberculosis tests
MIT chemists found a way to identify a complex sugar molecule in the cell walls of Mycobacterium tuberculosis, the world’s deadliest pathogen. This labeling could lead to simpler, faster TB tests.

Cutting-edge tools for structural biology: bringing AlphaFold to the people
The recent application of artificial intelligence-based prediction of protein and protein complex structures by AlphaFold has revolutionized biology. Here, we give an overview of the tools that make this revolution accessible to experimental microbiologists without training in bioinformatics or sophisticated computer equipment, and show how this helps to gain new insights.

The axolotl has the ability to regenerate its brain.

Using single-cell transcriptomics, four Science studies in 2022 revealed evolutionary innovations in reptile and amphibian brains.

Learn more during #AmphibianWeek: scim.ag/3EEKMxZ
The axolotl, represented here by the Mexican axolotl Ambystoma mexicanum, has the ability to regenerate its brain. In this 2022 issue, a group of four papers profiles amphibian and reptile brain neurons with single-cell transcriptomics. Analyses lend insight into why the axolotl brain retains regenerative capability that the mammalian brain has lost as well as how structural brain innovations arose during evolution.

I had an undergrad professor that told me never trust a scientist who can’t cook. And I actually think that’s true!”
