Virus exploitscellular waste disposal system

ETH Zurich researchers demonstrate how vaccinia virus manipulates the cellular waste-disposal system and thereby cleverly tricks the cell into assisting the intruders replication. Now, the virologists have turned the tables, ...

Trifunctional molecule decodes cellular communication

(Phys.org)—How does one define the factors on the surface of human cells to which a molecule of interest binds? This question is typically hard to answer. Researchers of ETH Zurich have developed a new technology that enables ...

How is a Kindle like a cuttlefish

(Phys.org)—Over millions of years, biological organisms – from the chameleon and cuttlefish to the octopus and squid – have developed color-changing abilities for adaptive concealment (e.g., camouflage) and communication ...
