(Phys.org) —No two biological cells are exactly the same. Even a small biopsied tumor sample contains cells with large variations in their proliferation rate, potential for metastasis, drug responsiveness, etc. However, ...
Researchers at the University of Exeter, U.K., have discovered intricate mechanisms of ligand–receptor complex transport via specialized protrusions transporting signaling components between cells, challenging the conventional ...
Biologists from ETH Zurich have discovered speargun-like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used by the microbes for the ...
