This study establishes merotelic kinetochores as a new experimental model for studying the mechanical response of the kinetochore. By combining laser microsurgery and live-cell imaging in yeast and mammalian cells the study shows a conserved viscoelastic response of the kinetochore.

Physics and biology have a lot in common. Similarly to atoms in a box in a thermal equilibrium, genes that affect quantitative traits can be seen as maximizing their level of disorder, measured by entropy, while keeping a few key quantities fixed. This principle holds when the evolutionary forces are in balance, i.e., when the system is stationary. However, we show that even when the system is non-stationary, a variation of the approximate maximum entropy principle holds. This approximation is very...

Measuring DNA repair is attractive for cancer diagnostics and in predicting anticancer drug resistance. However, no simple method to measure their enzymatic activity exists. By using a fluorescent DNA probe, the activity of a clinically-relevant DNA repair enzyme can be measured in a high throughput manner and be quantified within cancer cellular lysates and live-cells.

The genetic code provides more than one codon for almost every proteinogenic amino acid. In all genomes, synonymous codon usage is non-random. Variations due to silent single nucleotide polymorphisms (sSNPs) can change functional properties of proteins and lead to disease. Studies on the eye lens protein gamma-B crystallin demonstrate that sSNPs alter the conformational ensemble of the mature protein and affect protein yield and solubility. sSNPs modulate the rates of mRNA translation and co-translational...

Like man-made machines, cells are organized by functional modules, which contain components whose removal severely compromises the module's function. By evolving budding yeast after deleting an important component, we found that the perturbed module was repeatedly repaired by removing more components.

The ability to precisely express any desired time-varying concentration of a protein of interest in a cell is of paramount importance in order to quantitatively describe the mechanisms of gene regulation in dynamical biological processes, such as cyclic gene expression (genetic oscillators). We developed innovative microfluidic 'lab-on-a-chip' devices in conjunction with time-lapse microscopy for both yeast and mammalian cells able to trap single cells, or small populations of cells, for...

Different bacterial species use different variations of pirouettes to detach from surfaces, due to hydrodynamics.

Actin cables are crosslinked actin filament bundles that are nucleated by formin proteins in yeast. Actin cable regulates numerous biological processes for polarized cell growth, during which the cell cycle regulates the assembly and organization of actin filament. We report a phosphoregulation of actin crosslinking protein Sac6 by cyclin-dependent kinase 1 in budding yeast.

The brain is divided into functional circuits, each specialized for specific tasks: perception, memory, spatial navigation... How do these circuits work as a team when required? New research shows that when a rat is engaged in a tactile recognition task and needs to make a spatial choice based on previous knowledge, the animal's sensory, motor, and memory regions fall in step to a well-timed rhythmic choreography.

Have you ever walked through a forest in the fall or through a meadow in late summer and wondered why trees and flowers shed their leaves? They are simply getting rid of organs that are no longer needed, preparing for the next step in their life cycle. But how does a leaf know when to let go? This process is regulated by the cell surface receptor HAESA, present in cells forming the tissue around the future break point. When it's time to shed an organ, a small peptide hormone called IDA instructs...
