blog postsStudy shows how bacteria guide electron flow for efficient energy generationMay 14, 2018 8:30 am584 views Biochemists at the University of Illinois have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane. The voltage is used to make ATP, a key energy currency of life. The new findings, reported in the journal Nature, will inform future efforts to obtain the atomic structures of large membrane protein supercomplexes.Elastic microspheres expand understanding of embryonic development and cancer cellsMay 14, 2018 6:00 am611 views A new technique that uses tiny elastic balls filled with fluorescent nanoparticles aims to expand the understanding of the mechanical forces that exist between cells, researchers report.
