New #ISEPpapers! Hijacking and integration of algal #plastids and #mitochondria in a polar planktonic host: Ananya Kedige Rao et al. https://www.cell.com/current-biology/fulltext/S0960-9822(25)00392-6
"Hosts steal active plastids, mitochondria, and nuclei from the microalga #Phaeocystis... Stolen plastids increase in volume, and their photosynthetic activity is boosted... Stolen mitochondria transform into a network in close association with plastids"
We’re capturing the energy of #biologists100 by walking around with a polaroid frame, highlighting the incredible early-career researchers at the conference! ✨
We’re kicking things off with @JontyTownson, the #preLights conference reporter, who is uncovering the stories behind the #preprints being presented.
If you're at the meeting, please come say hi + get your snapshot! 📸
Introducing the “nitroplast”
A cell pulls off one of the 'Holy Grails' of biotechnology https://www.npr.org/2025/03/18/nx-s1-5330385/a-cell-pulls-off-one-of-the-holy-grails-of-biotechnology #biotech #organelles #nitrogen #endosymbiosis (maybe?)
New research on #protists sheds light on #DeepSea energy sources https://www.whoi.edu/press-room/news-release/foraminifer/
Array of metabolic pathways in kleptoplastidic #foraminifera supports #chemoautotrophy in dark, euxinic seafloor sediments https://academic.oup.com/ismej/article/19/1/wrae248/7923457 by Fatma Gomaa et al.
"This species takes up unrelated organism’s #chloroplasts — #organelles that perform #photosynthesis... We know #kleptoplasty is happening here, but we needed to understand why this foraminifer is so successful in the dark, without oxygen"
Teaching about cells, organelles, cell transport or reproduction, etc.? I have resources to share.I’ve taught high school for many years, SPED to Honors. The differentiation & adaptations I made for SPED became sought after by other students, even at Honors level. I've worked hard at developing a helpful sequence of ideas, embedded vocabulary support, step-by-step graphics, and analogies.

A single cell's siesta: How non-moving #microbes manage to avoid bright light https://phys.org/news/2024-11-cell-siesta-celled-bright.html
Light-regulated #chloroplast morphodynamics in a single-celled dinoflagellate https://www.pnas.org/doi/10.1073/pnas.2411725121
"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."

Protein shell discovery reveals how #diatoms capture CO₂ so effectively https://phys.org/news/2024-10-protein-shell-discovery-reveals-diatoms.html
"diatom pyrenoids are encased in a lattice-like protein shell... not only gives the pyrenoid its shape, but it helps create a high CO2 concentration in this compartment. This enables Rubisco to efficiently fix CO2"
