A newly found organelle, the hemifusome, helps manage cellular recycling. It may play a role in inherited diseases and open paths to new therapies. Scientists have identified a previously unknown ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025 ...

The researchers also found that endocytosis, the cellular process that helps shuffle proteins to and from the cell membrane, was significantly impaired in the myosin XI mutants.

Their exocytosis in the growth cone depends on the exocyst complex that mediates the tethering of vesicles at the cell membrane prior to their fusion. It is localized to the membrane by the binding of ...

What is cancer? Cancer starts when cells change abnormally Cancer is when abnormal cells divide in an uncontrolled way. Some cancers may eventually spread into other tissues. There are more than 200 ...
