"CLOCKWISE-rotating petals are found, for example, in oleander, whereas petals of the greater periwinkle are arranged in an anticlockwise fashion." https://lnkd.in/eNvcnv7 View in LinkedIn

"THE BRAIN-GUT AXIS is a bidirectional communication system between the central nervous system and the gastrointestinal tract. Serotonin functions as a key neurotransmitter at both terminals of this network. Accumulating evidence points to a critical role for the gut microbiome in regulating normal functioning of this axis." https://lnkd.in/enJwVms View in LinkedIn

"PETALS of several species are arranged like fan blades that all seem to twist in the same direction, forming either a clockwise or an anticlockwise appearance." https://lnkd.in/eNvcnv7 View in LinkedIn

FRAGMENT IN NATURE this weekend focuses on the gut-brain axis, and recent evidence that it is our "second brain", driven by the gut microbiome. This extraordinary new perspective of our most fundamental anatomy and physiology is sure to eventually change the way that we view and manage our health and disease. View in LinkedIn

"ROOTS, hypocotyls, shoots, branches and flower stalks may oscillate either in a clockwise or anticlockwise direction, strictly in a growth-dependent manner." https://lnkd.in/eNvcnv7 View in LinkedIn

THE CHIRALITY GENE in snails. "The general solution to the problem of symmetry breaking is provided by a pre-existing asymmetric molecular reference, or F-molecule...Asymmetry is thus entirely dependent on the chirality and alignment of the F-molecule," (now called NODAL). https://lnkd.in/eRqXtYc View in LinkedIn

GROWING TENDRILS of twining plants are chiral: "runner bean and bindweed make right-handed helices, whereas hop and honeysuckle produce left-handed helices," showing anisotrophic growth patterns. https://lnkd.in/eNvcnv7 View in LinkedIn

THE SNAIL NODAL GENE controls the body orientation in many (or most) species, discriminating between left and right, top from bottom and back from belly. It is critical in determining symmetry during development. https://lnkd.in/emDBBtm View in LinkedIn

CHIRALITY and unusual optical and consequent electrical properties of materials, including liquid crystals, is the subject of this in depth review, which is a linear continuation of the early observations of Pasteur, except with vastly more powerful tools and the benefits of an army of scientists, and of course, time. https://lnkd.in/etPP69n View in LinkedIn

THE GENETIC BASIS of chirality in shells is quite simple. "Chirality is determined by a single gene or a small set of genes inherited from the mother, with the right-hand twist form being dominant." https://lnkd.in/eWG5ySJ View in LinkedIn
