15-05-21 New research from the University of Southampton has identified how changes in the cell membrane play a pivotal role in how the Hepatitis C virus replicates. By understanding this process, the researchers hope to investigate how to prevent the change...

14-09-11 G protein-coupled receptors (GPCRs) are the largest class of cell surface receptors in our cells, involved in signal transmission across the cell membrane. One of the biggest questions is how a signal recognized at the extracellular side of a GPCR i...

13-11-02 The ever-increasing threat from superbugs -- strains of pathogenic bacteria that are impervious（不受影响的） to the antibiotics that subdued their predecessor（前辈） generations -- has forced the medical community to look for bactericidal weapons...

13-10-24 Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function. Channels in cell membranes help direct these proteins to their appropriate target. Researchers at Boston University School of M...

13-09-21 Why don't trees bleed to death when they are injured? Researchers from Virginia Tech, the Georg-August University of Gottingen, Germany, and the Jackson Laboratory of Bar Harbor, Maine, have discovered how check valves（止回阀） in wood cells contro...

13-08-23 Cells are very good at protecting their precious contents -- and as a result, it's very difficult to penetrate their membrane walls to deliver drugs, nutrients or biosensors without damaging or destroying the cell. One effective way of doing so, dis...

12-10-24 Much has been made of graphene's exceptional qualities, from its ability to conduct heat and electricity better than any other material to its unparalleled（无比的） strength: Worked into a composite material, graphene can repel bullets better than...
