Performing cellular surgery with a laser-powered nanoblade

To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers reporting May 10 in Cell Metabolism describe ...

Squished cells could shape design of synthetic materials

Life is flexible. All living cells are basically squishy balloons full of water, proteins and DNA, surrounded by oily membranes. Those membranes stand up to significant amounts of stretching and bending, but only recently ...

Breaking cell barriers with retractable protein nanoneedles

The ability to control the transfer of molecules through cellular membranes is an important function in synthetic biology; a new study from researchers at Harvard's Wyss Institute for Biologically Inspired Engineering and ...

Cell morphology shapes protein patterns

Precise control of thedistribution of specific proteins is essential for many biological processes. An LMU team has now described a new model for intracellular pattern formation. Here, the shape of the cell itself plays a ...

Viscous nanopores collapse according to universal law

Viscous nanopores, tiny holes punctured in fluid membranes, collapse according to a universal law, a Purdue University study shows. The finding could improve the design of nanopores for fast, inexpensive DNA analysis and ...

How lipids are flipped

A team of researchers at ETH Zurich and the University of Bern has succeeded in determining the structure of a lipid flippase at high resolution, which has provided insight into how this membrane protein transports lipids ...

Manipulating cell membranes using nanotubes

Japanese researchers have developed a targeted method for opening up cell membranes in order to deliver drugs to, or manipulate the genes of, individual cells.
