"HOMOCHIRALITY of biological amino acids (L-amino acids) and of the RNA/DNA backbone (D-ribose) might have have become established on the primitive earth." https://lnkd.in/e7QJSwN View in LinkedIn

NEUROGASTROENTEROLOGY. "The second brain, located in the bowel, normally works smoothly with the brain in the head, enabling the head-brain to concentrate on the finer pursuits of life while the gut-brain attends to the messy business of digestion." https://lnkd.in/e7N4hyj View in LinkedIn

NATURE has generally segregated two great living Kingdoms by the chirality of their molecules. The majority of living organisms have (mostly) only one type, while bacteria have (mostly) the opposite. Curiously, partly with advances in detection, the bacterial chirality has been found to play key roles in non-bacterial life forms. View in LinkedIn

"THE ENTERIC NERVOUS SYSTEM is the largest and most complex division of the peripheral and autonomic nervous system in vertebrates." https://lnkd.in/eUENUkX View in LinkedIn

"DROPLETS present arguably the simplest and most symmetric confining container for liquid crystals." https://lnkd.in/ejxwdgM View in LinkedIn

SECOND BRAIN. "The enteric nervous system can operate autonomously and has been likened to a second brain." https://lnkd.in/eDFWAiD View in LinkedIn

"TWO BRAINS may seem like the stuff of science fiction, but they make literal and evolutionary sense." https://lnkd.in/edr6xim View in LinkedIn

FRAGMENT IN NATURE continues with the enteric nervous system, or the gut-brain axis. One important aspect of this axis is now appreciated to be the microbiome, and recent evidence suggests that when the host is stressed, it can change the composition of the microbiome in favor of pathogenic microorganisms.

"FREE D-AMINO ACIDS are abundant in bacteria and in certain animal tissues, and they may be synthesized in animals as in bacteria...D-amino acids appear to be not only remnants of ancient life but prerequisites for present-day life." https://lnkd.in/ermi4iJ View in LinkedIn

UNANTICIPATED ROLES. "D-amino acids have previously unappreciated regulatory roles in the bacterial kingdom. Many diverse bacterial phyla synthesize and release D-amino acids, including D-Met and D-Leu, which were not previously known to be made." https://lnkd.in/eXp7iyx View in LinkedIn
