- Breakthrough results in developing an oral insulin tablet: This method makes use of the thin membrane found within the lining of the inner cheek and back of the lips. It delivered all the insulin to the liver without wasting or decomposing any insulin along the way. https://www.nature.com/articles/s41598-022-13092-6 71 comments science
- Breast cancer cells use force to open channels through tissue: Previously, researchers thought that cells use enzymes to dissolve membranes, but now it is understood that breast cancer cells use forces generated by the protrusions to open up channels within the membrane material. https://pubs.acs.org/doi/10.1021/acs.nanolett.2c01327 4 comments science

- New research shows how general anesthesia induces unconsciousness. A "billiard-like break shot" scatters lipid clusters in cell membranes, which releases an enzyme that liberates potassium from ion channels, leaving neurons hyper-polarized and inhibiting their ability to fire. https://www.scripps.edu/news-and-events/press-room/2020/20200529-hansen-lerner-anesthesia.html 1129 comments science

Protein attachment to the membrane of a starfish egg cell occurs in rippling waves,displaying patterns of turbulence that resemble those seen throughout the physical world -- interacting in much the same way as particles of opposite electrical charge. https://www.nature.com/articles/d41586-020-00881-0 15 comments science
- Mild depolarization of the inner mitochondrial membrane is a crucial component of an anti-aging program. In short-lived mice, aging is accompanied by inactivation of mild depolarization mechanism, but this is absent in long-lived naked mole rats and bats. https://www.pnas.org/content/early/2020/03/03/1916414117?ct 4 comments science

- Scientists coaxed brain membrane cells from a human into stem cells, which grew into brain organoids. After incubation, they transplanted an organoid into a cavity in a mouse’s brain. Two weeks later the organoid was alive, and had grown capillaries that penetrated all the way to its inner layers. https://www.wired.com/story/mini-brains-just-got-creepiertheyre-growing-their-own-veins/ 29 comments science
