Summary: In budding yeast, the Mnemon element Whi3(mnem) undergoes super-assembly to encode a mating pheromone refractory state in the mother cell. However, in the first cell division after establishing this state, the adaptation is more likely to be inherited by the daughter cell. This inheritance pattern is associated with cytokinesis defects and altered confinement of the cellular memory.

Summary: The study showed that the glycerol concentration affects the division mode of mycobacterial cells, with a ratio of approximately 50:50 for asymmetric constriction to symmetric constriction when glycerol is maintained at 0.1%. The involvement of specific enzymes in the response to glycerol levels and the physiological significance of the observed changes were also discussed.

Summary: We developed a multi-stage cell lineage model to study the dynamics of stem cells and their progeny. The model incorporates self-renewal, apoptosis, cell movement, and symmetric/asymmetric cell division. Our results show that asymmetric cell division of stem cells can influence the population size and spread of the cell lineage. Additionally, the speed of stem cell propagation can be evaluated using asymmetric cell division. These findings suggest a mechanism for collective migration of cell lineages through the cooperation of stem cell division and fast diffusion of progeny cells.

Summary: In their latest article, Seki and colleagues investigate the potential role of cold exposure in treating various cancer types, including untreatable ones like pancreatic cancer. They suggest that cold exposure may suppress tumor growth by activating brown adipose tissue (BAT), which dissipates heat through non-shivering thermogenesis. This leads to decreased circulating blood glucose, limiting tumor glucose uptake and favoring BAT uptake for thermogenesis.

Summary: Plant cells exhibit polarity, and this polarity can be coordinated through mechanical stresses. In cotyledons, there are two coordinated biases in planar polarity: mediolateral and proximodistal. These biases are not significantly affected by applied tension.

Summary: This study explores the impact of terrorism and foreign direct investment inflows on carbon dioxide emissions in ten global economies most impacted by terrorism. The results reveal non-linear relationships among terrorism, FDI inflows, economic growth, and energy consumption with carbon dioxide emissions. Recommendations include focusing on education, employment, economic stability, and public awareness to combat terrorism, as well as implementing strict environmental regulations on FDI inflows to mitigate adverse environmental effects. International firms should be encouraged to invest in cleaner technologies to reduce emissions.

Summary: In this study, a strategy to design asymmetric building blocks for COF synthesis is introduced, and two isomeric hexaphenylbenzene-based two-in-one type monomers are designed and synthesized. Surprisingly, the self-polycondensation of the asymmetric monomer also forms highly crystalline COF with an identical topological structure to its symmetric counterpart. This work demonstrates the potential of using asymmetric building blocks in COF synthesis and provides a new structural design strategy for reticular chemistry.

Summary: The even and odd symmetries of two-dimensional multi-element phase gratings have been explored to manipulate diffraction columns and rows. By adjusting the offset refractive indices, different types of destructive interference can be achieved, resulting in directional column elimination, grouped column elimination, directional column selection, natural row absence, grouped row elimination, and central row selection.

Summary: This paragraph describes a drug for treating multidrug-resistant tuberculosis, which targets the key enzyme ATP synthase in cellular respiration. A recent study shows that this drug, along with another inhibitor, prevents the enzymatic function by inhibiting the necessary rotational motions.

Summary: A Cartesian grid based sharp interface multiphase flow model is developed to investigate the impact of a wedge with sharp phase changes. The model incorporates various methods to handle transient phase change, moving boundaries, and free surfaces. The accuracy and capability of the model are demonstrated through simulations and comparisons with experimental data. The model performs well for various impact angles except for nearly flat plate slamming, while the diffuse interface model is only effective for larger impact angles. The study also analyzes the variation rules of impulsive pressure, motion response, pressure distribution, and free surface motion with respect to impact angle.

Summary: In this study, the stability of radially symmetric growth in tumor spheroids was investigated using a reaction-diffusion model. The results showed that under symmetric growth conditions, small asymmetric perturbations could change the shape of the tumor, indicating that the spherical configuration of tumor spheroids is naturally unstable.

Summary: This study reanalyzes the binary data from Kepler and TESS missions and focuses on tidal circularization. It finds that circularization occurs at a period of around 6 days for nearly circular binaries with long orbital periods, but occurs at a period of around 3 days for binaries with moderate eccentricities. The study also highlights the significant difference in eccentricity distributions between young and old binaries.
