01Cells temporarily suppress many DNA-repair pathways during mitosis. A Cell study shows that DDIAS protects exposed single-stranded DNA and is particularly important for developing neural cells.
02Repeated mild mechanical injury left human astrocytes in a persistently altered state. Their lipid output changed, and medium from the injured cells impaired human neurons in an in-vitro model.
03Frog-cell xenobots can generate new motile aggregates without dividing. The study reveals a form of kinematic self-replication driven by movement, cell gathering, and body geometry rather than genetic modification.
04Born on July 27, 1881, Hans Fischer revealed the chemistry behind heme and helped connect the red pigment of blood with the green pigment of plants. His work transformed natural colors into precise molecular structures.
05Almost every human cell contains about two metres of DNA. How does the cell pack this enormous molecule into a microscopic nucleus while keeping the right genes accessible?
