VIBRATING SIGNAL. “When the slime mold senses attractants, such as food, via specific binding to receptor molecules presented on the outer membrane surface, the oscillation frequency in the area closest to the food increases, causing cytoplasm to flow toward the attractant. Additionally, binding of attractant molecules to sections of the surface membrane reduces the tension at that section, leading to a difference in internal hydrostatic pressure, such that cytoplasm flows toward the source of attractants.” http://www.pnas.org/content/109/43/17490.full View in LinkedIn

ALL MOLECULES TURN OVER. "In 1891 August Weismann proposed that the germ plasm is immortal. Yet, the repeated replication and repair of DNA results in molecules that do not contain atoms of the same nucleotides present in the DNA of a founding cell." (L. Haflick, the brilliant contrarian, adopting an overly rigid definition of immortality). https://lnkd.in/esfPTAR View in LinkedIn

OSCILLATING UNITS. “The slime mold Physarum polycephalum is a unicellular, multinucleate protist that relies on reactive navigation to explore its environment. The vegetative state of P. polycephalum (known as a plasmodium) is composed of many smaller oscillating units. Each unit oscillates at a frequency dependent upon both the local environment and its interactions with neighboring oscillators.” https://lnkd.in/gxeWCUg View in LinkedIn

TWO FATES. "Epigenetic information is frequently erased near the start of each new generation. In some cases, however, epigenetic information can be transmitted from parent to progeny (multigenerational epigenetic inheritance)." http://www.nature.com/nature/journal/v489/n7416/abs/nature11352.html View in LinkedIn

REPROGRAMMING. "It has long been suspected that epigenetic modifications could play a role in limiting the developmental potential of a tissue during the complex pattern of tissue differentiation. This has led to the idea that a fundamental aspect of the difference between the ‘‘mortal’’ soma and the ‘‘immortal’’ germline may be the ability to reprogram the genome of the germ cells epigenetically in order to maintain totipotency."
