Researchers have developed a particularly simple model that reproduces the swimming mechanism of amoebas. They show that, by changing shape, these single cell organisms propel themselves forward in a ...

Cancer is one of the leading causes of death worldwide, marked by the uncontrolled growth of abnormal cells. What makes it more dangerous is the ability of cancer cells to move quickly through the ...

Rhythmic patterns and precise motions are key elements of proper swimming, and comparable demonstrations of this pattern repetition and power usage can be seen in a microscopic swimmer -- the amoeboid ...

Calcium/calmodulin-dependent protein kinase II (CaMKII) gathers inside a growing membrane bleb, creating a local increase in water pressure. This pressure draws in water and pushes the cell membrane ...

An important feature of T lymphocytes is their migration through tissues in search of antigen presenting cells (APC) bearing peptide–MHC complexes. Both motility rate and access to tissues by T cells ...

Scientists headed by a team at the University of Tokyo have identified a protein, known as podoplanin (PDPN), that is common to both human and canine mucosal melanoma, and which appears to mobilize ...

In a new theory to explain the mechanism of motility in amoebae and similar cells,the author proposes that streaming cytoplasm contracts at the front of the cell and literally pulls it along ...

WASHINGTON, D.C., October 31, 2017 -- Rhythmic patterns and precise motions -- these are key elements of proper swimming. Olympians demonstrate repeated patterns of breathing, with synchronized head, ...
