Today is National Pumpkin Seed Day. Pumpkin seeds, also known as pepitas, are native to the Americas. They were discovered by archaeologists in Mexico in caves that date back to 7,000 B.C. Today, China produces more pumpkins and pumpkin seeds than any other country.  Pumpkin seeds are loaded with protein; a single cup provides 8-10 grams of protein. They are packed with nutrients and they are overall very good for your health.  Next time you are whipping up a batch of protein bites; don't forget pumpkin seeds. Just mix up dates, whole nuts, chia seeds, sesame seeds, sunflower seeds, pistachios, almonds, pumpkin seeds, 1tsp cacao bio powder, 1tsp peanut butter, a handful of raisins and dried cranberries. Then press the mixture into a pan and slice into bars. Couldn't be simpler.     Brevities #OTD  Today is the birthday of the German botanist known as the Father of Plant Physiology, Julius von Sachs, who was born on this day in 1832.   In the 1860's, Sachs tested adding a variety of nutrients to plants growing in water. He was trying to determine what plants need to live. It was early, early efforts on modern day hydroponics. In 1864, Sachs determined that blue light is the most important color for inducing phototropism in plants. Plants are generally blind to other colors; which is why you don't see plants bending toward the lamps inside your house; unless you are using grow-lights!   In 1868, Sachs became Head of the botanical institute at Würzburg University.  Sachs was a good friend of Frank Darwin. When Darwin needed a lab to conduct his experiments plants of growing toward light, he naturally used the world-class lab of his friend, Julius von Sachs, at Würzburg U.   Sachs himself was studying how plants process light. He correctly identified that starch was a product of the sunlight process known as photosynthesis. He proved that chlorophyll in chloroplast is involved in photosynthesis. Sachs is responsible for identifying structures like the organelle and chloroplasts.    Sachs used some ingenuity helped him come up with things like planter boxes with one glass side so that he could better understand the formation of roots. Using a magnifying glass, he could discern the development of root hairs and cellular protrusions.          #OTD  On this day in 1836, the HMS Beagle returned to England after a five year voyage around the world.  It was a revelatory trip for ship’s naturalist, Charles Darwin, who found the building blocks to his evolutionary theory in the many fossils and diverse species he discovered on his excursions. It would be another 23 years before he published the Origin of Species. Often, Darwin is depicted on the Beagle as an old man; but he was just 22 when he sailed away and still a young 27 when he returned with boxes full of specimens and a brain swirling with new ideas.       #OTD  Today is the 165th birthday of the Father of Town Planning and a botanist, Patrick Geddes, who was born on this day in 1854. Geddes accomplished much during his lifetime, despite being notoriously disorganized and easily distracted. In addition to his work in planning, Geddes was an ardent botanist and an environmentalist. People often forget that Geddes was trained most in the subjects of biology and botany; it was through that living scientific lens that he was first inclined to view the world. Geddes always conceded an undeniable truth in his work; nature is ever-changing and humans need to be in nature. Geddes had a profound appreciation and reverence for life. Like any gardener; he saw value in beauty. Geddes wrote: "No one who studies animate nature can get past the fact of beauty. It is as real in its own way as the force of gravity." When it came to planning towns, Geddes dismissed modernist plans for creating what he called "soulless suburbs and concrete slums". Instead, the ever-practical Geddes bought land in Edinburgh and created communities interwoven into the landscape. Bare spots on plans wer
