The ever-increasing threat from "superbugs" -- strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations -- has forced the medical community to look for bactericidal weapons outside the realm of traditional drugs.

Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function.

Cell biologists at The Johns Hopkins University have teased apart two integral components of the machinery that causes cells to move.

Molecular Muscles Inside Cells Help Them Sense, Respond To Their Environments

Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities.

Researchers around Dr. Michael Hirtz from Karlsruhe Institute of Technology and Dr. Aravind Vijayaraghavan from the University of Manchester have developed a new method to produce artificial membranes: Using a nanoscaled tip, they write tailored patches of phospholipid membrane onto a graphene substrate.

The membranes surrounding and inside cells are involved in every aspect of biological function.

Eukaryotic cells are compartmentalized by membranes, whose shape and dynamics are precisely regulated to maintain their correct functions.

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.


Word of the Day
pawl
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
