How plants sense touch, gravity and other physical forces

(PhysOrg.com) -- At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation of the membrane. ...

Envelope for an artificial cell

(PhysOrg.com) -- Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain ...

Escherichia coli bacteria produce diesel on demand

It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand. While the technology still faces many significant commercialisation ...

Scientists dissociate water apart efficiently with new catalysts

University of Oregon chemists have made substantial gains in enhancing the catalytic water dissociation reaction in electrochemical reactors, called bipolar membrane electrolyzers, to more efficiently rip apart water molecules ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
