How proteins reshape cell membranes
Small 'bubbles' frequently form on membranes of cells and are taken up into their interior. The process involves EHD proteins. Scientists have now shed light on how these proteins assemble on the surface of a cell and reshape its membrane.

New link found between sex and viruses
Sexual reproduction and viral infections both rely on a functionally identical protein, according to new research. The protein enables the fusion of two cells, such as a sperm cell and egg cell, or the fusion of a virus with a cell membrane. The discovery suggests that the protein evolved early in the history of life on Earth, and new details about the protein's function could help fight parasitic diseases such as malaria.

Viruses support photosynthesis in bacteria
Viruses propagate by infecting a host cell and reproducing inside. This not only affects humans and animals, but bacteria as well. This type of virus is called bacteriophage. They carry so called auxiliary metabolic genes in their genome, which are responsible for producing certain proteins that give the virus an advantage. Researchers have analyzed the structure of such a protein more closely. It appears to stimulate the photosynthesis of host bacteria.

ORC as loader of the rings: Study details ringed structure of ORC in DNA replication
An international collaboration of life scientists has described in exquisite detail the critical first steps of DNA replication, which allows cells to divide and most advanced life, including human, to propagate.
