CHARGE AND GEOMETRY. “Simply due to their geometry, protruding floral structures such as a long stigma will create a strong local electric field (Fig. 7a, b), and indeed, flowers with a flat corolla and long stigma appear to capture more pollen through electrostatic forces than those with concave corolla and shorter stigma.” https://lnkd.in/dz2UJCDk View in LinkedIn

GEOMETRY IS KEY. “Just as morphology, geometry and specific impedance of structures are key influences on the electric field at the scale of trees and plants (Fig. 2), this remains true at the smaller scale of a flower’s anther, stigma, and pollen grain.” https://lnkd.in/dz2UJCDk View in LinkedIn

POLLEN FUNCTION. “During the bee’s final approach to the flower, electrostatic forces between these two bodies grow rapidly larger (Fig. 5). This has been suggested to have important consequences for pollen transfer from anther to bee and back from bee to stigma.” https://lnkd.in/dz2UJCDk View in LinkedIn

LANDING GUIDES. “At a distance of 2–3 cm shown in Fig. 4, the region between the bee and the flower has an electric field of over 5 kV/m. This is comparable in magnitude to the electric field at the ground under a high-voltage power line. This field strength is much higher than that required to elicit mechanical and neural responses from bumble bee hairs.” https://lnkd.in/dz2UJCDk View in LinkedIn

LOCAL FIELDS. “The bee carries a positive charge that it acquires while flying. The flower gains a negative charge through electrostatic induction. The forces that exist between charges fall off with the square of their distance, so that the forces between bee and flower increase quickly as the bee approaches.” https://lnkd.in/dz2UJCDk View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this one on the theme of the electrostatic relationship between bees and flowers. The more that we study nature, the more levels of complexity emerge; in this case, the coevolution of two unrelated species have found nuanced ways to communicate, previously invisible to us. Nature continues to reveal her secrets. View in LinkedIn

VISUALIZATION. “The anti-universe should be observable by gravitational lensing, predicting "MACHOS" of approximately stellar mass, and multiple micro-lensing of quasars. Non-existence of primordial antimatter of Z > 1, and a large variation in the quantities of dark matter associated with different individual galaxies are predicted.” https://lnkd.in/gDaxUYAS View in LinkedIn

TWO UNIVERSES. “The remaining opposite partner particles left by the leakage, (antimatter and matter respectively) proceeding outward in antitime and time respectively, after many annihilations also increase the two preponderances in the two universes.” https://lnkd.in/gDaxUYAS View in LinkedIn
