Microtubules, Motor Proteins And Nano-patterning

Two kinds of kinesin molecular motors have different properties of coordination, Kyoto University’s School of Engineering has found. The findings were made possible thanks to a new tool the team developed that parks individual motors on platforms thousands of times smaller than a single cell. “Kinesin is a motor protein that is involved in actions such as cell division, muscle contractions, and flagella movement. They move along these long protein filaments called microtubules. [Read More]

A Transporter Protein For Pumping Antibiotics Into Bacteria

A cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, researchers in the University of Wisconsin-Madison Department of Biochemistry have discovered. The finding could revise almost 50 years of thinking about how these types of transporters function in the cell. Cells must bring in and remove different materials to survive. To accomplish this, they utilize different transporter proteins in their cell membranes, most of which are powered by what is called the proton motive force. [Read More]

Smartphone Display Lighting Can Activate Live Cells

Lighting technology used in smartphone displays is able to activate live cells that are genetically programmed to respond to light, scientists at the University of St Andrews have revealed. The findings as “a bit like cells watching TV”, in the words of Professor Malte Gather from the School of Physics and Astronomy, who led the research. Using the ability of organic light emitting diodes (OLEDs) to “switch on” individual cells in the lab opens the door to cell-specific optogenetic control in cultured neuronal networks, brain slices, and other biomedical research applications.
