A team of researchers at the RIKEN Center for Biosystems Dynamics Research in Japan has developed a tool to prevent neurogenerative diseases. They have demonstrated a way to observe the molecular mechanism that switches control ...
Cells are complex, multi-compartmentalized entities of matter enclosed with a variety of membrane-bound organelles ranging from the microscale (µm) down to the nanoscale (nm) in diameter. These structures intermingle in ...
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
