How lipids are flipped

A team of researchers at ETH Zurich and the University of Bern has succeeded in determining the structure of a lipid flippase at high resolution, which has provided insight into how this membrane protein transports lipids ...

Building a better microscope to see at the atomic level

One of the more famous images in biology is known as "Photo 51," an image of DNA that chemist Rosalind Franklin and Raymond Gosling created in 1952 by shooting X-rays through fibers of DNA and analyzing the patterns they ...

New measures call theories about endocytosis into question

Cellular biology still harbors mysteries. Notably, there is no unequivocal explanation behind endocytosis, the biological process that allows exchanges between a cell and its environment. Two hypotheses prevail for explaining ...

Research shows relationship critical for how cells ingest matter

To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the ...

Cell division, minus the cells

(Phys.org) —The process of cell division is central to life. The last stage, when two daughter cells split from each other, has fascinated scientists since the dawn of cell biology in the Victorian era. For just as long, ...
