Autumn begins with mitoses. Cell division will not succeed without this unusual protein

Mitosis, the process that leads to the creation of two identical daughter cells from one cell, is the foundation of life, growth and reproduction. It seemed that it was already a well-understood process. Meanwhile, another brick has been added to the knowledge about it.

    Scientists identify protein that allows us to sense cold

    Scientists from Poland and Italy have identified the structure of the protein responsible for sensing cold. This protein plays a role in soothing pain, among other things, which is why in the future their findings may contribute to the development of new medical therapies for neuropathic pain and irritable bowel syndrome.

The mystery of Type Ic supernovae: Dramatic relationships of binary stars

Type Ic supernovae carry within them a dramatic story of a relationship between a pair of stars. An international team of scientists led by Polish researchers has proven that for this type of cosmic explosion to occur, a not-so-peaceful - by human relationship standards - binary star system is needed.
