Scientists reveal how sleeping sickness parasites control their surface coat Researchers have revealed how parasites hide thousands of antigens behind a single-colour coat and how disrupting this control could make the parasit...

New PNAS study identifies ESBX, a protein controlling which surface coat gene is active in sleeping sickness parasites - key to immune evasion.

The discovery of the first kinetochore proteins (CENP-A, CENP-B, CENP-C) was reported by Bill Earnshaw and Naomi Rothfield in 1985 in Chromosoma. Forty years later, Chromosoma/Chromosome Research has published a special issue (most articles are open access)

New in ACS SynBio: led by Dennis Bolshakov, we used the awesome power of yeast to define how expression levels, noise, and sequence program the dynamics of synthetic protein waves, allowing us to genetically encode new cellular timescales stable over generations!

Right: Individual cell lines were generated via endogenous tagging and imaged through fluorescence microscopy for comparison with the compartment-relevant protein was predicted to. Merged microscopy images showing protein signal (green) merged with nuclear and mitochondrial DNA (blue). All imaged cells are oriented with their apical regions facing right and posterior facing left, cell membrane outlines are traced for all images except for L, showing only trace of the papilla, which lacks signal. Scale bar represents 5 ΞΌm.

How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Our new preprint describes Plasmodium NEK4 as a key regulator coupling meiotic initiation and morphogenesisβ€”a critical step for malaria transmission. This involves MTOC-driven nuclear movement strikingly analogous to "horsetail" movement in fission yeast.
