Guest posted a topic in TopicsOn St. Patrick's Day, everyone is seeing green—whether it's the green Chicago River, green beer, green milkshakes or green clothing and bead necklaces. Many might believe that the Emerald Isle and the color green are linked because of the country's verdant landscape, but the association actually traces its roots to Irish political history. In fact, blue is believed to have been associated with Ireland before green was. Henry the VIII claimed to be king of Ireland in the 16th century, and his flag at that point would have been blue. That's at least one reason why a blue flag with a harp is associated with the Irish President. (The harp is one of the two main symbols of Ireland, along with the Shamrock, and it dates back to the bards whose songs and stories were the chief entertainment in medieval Gaelic society.) A light blue became associated with the Order of St. Patrick, an 18th century era order of knights, perhaps to create a shade of blue for the Irish that was different from the royal blue associated with the English, says Timothy McMahon, Vice President of the American Conference for Irish Studies . McMahon argues the earliest use of green for nationalistic reasons was seen during the violent Great Irish Rebellion of 1641, in which displaced Catholic landowners and bishops rebelled against the authority of the English crown, which had established a large plantation in the north of Ireland under King James I in the early 17th century. Military commander Owen Roe O'Neill helped lead the rebellion, and used a green flag with a harp to represent the Confederation of Kilkenny, a group that sought to govern Ireland and kick out the Protestants who had taken control of that land in the north of Ireland. (They were ultimately defeated by Oliver Cromwell.) The color green cropped up again during an effort in the 1790s to bring nonsectarian, republican ideas to Ireland, inspired by the American revolution and the French revolution. The main society that promoted this idea, the Society of United Irishmen, wore green, especially an Irish version of the "liberty caps" worn during the French Revolution. One police report described their uniform as comprised of a dark green shirt cloth coat, green and white striped trousers, and a felt hat turned up on one side with a green emblematic cockade. Though the rest of the uniform eventually faded from popular wear, the importance of the color green spread, thanks in part to the poems and ballads written during this time, most famously "The Wearing of the Green." "You start to see different traditions building up around colors — the Protestant tradition is orange, the nationalist tradition associated with the Catholics is green," McMahon adds. The origins of the wearing of green clothing in the U.S. on St. Patrick's Day and for St. Patrick's Day celebrations in general date back to the 19th century, when waves of Irish immigrants came to America looking for better job opportunities, especially after the Great Famine of the 1840s-50s, and began wearing green and carrying Irish flags along with American flags as a point of pride for their home country. http://time.com/4699771/green-irish-st-patricks-day-color/
February 15, 2017 HAVANA TIMES — Organoponicos or urban organic farms in Cuba are a style of farming that can be used to produce vegetables, condiments, various crops and fruits. Tania Reyes Ferro, a 45 year old Cuban lady, is one of the few women who is in charge of an organoponico in the municipality of Candelaria. Her dedication and passion for her work give her the strength to continue on as a farmer. HT: Having an organoponico is good for your financial and food situation. What disadvantages are there to working the land? Tania Reyes: I studied agriculture but I never practiced it. I never thought that after all these years I would have a piece of land to cultivate. Working the land is hard. I’ve had problems with my cervix, backbone, waist, lower abdomen. I’ve been diagnosed with generalized osteoarthritis; when I suffer an attack and I can’t go to the fields, my children help me cook and do other chores. Whatever I collect is enough for us to eat at home. We use the money we get from selling extras to buy rakes, hoes, we don’t have the farm implements we need to do more work. HT: How much do you have to give to the State for farming? TR: We don’t produce very much on my plot, it’s just a hectare which I’ve divided into the garden and fruit trees. As the plot is very small, the only thing I have to do is give fresh condiments, vegetables and fruit to the maternity center and the Jose Luis Tacende primary school for disabled children. I pay a social contribution to the cooperative I belong to. HT: Do you use any chemicals on your crops? TR: No, there are many alternatives to getting rid of pests. For example, we collect seeds and leaves from the Neem Tree, which is a pesticide, we mash them up and let it set so we can fumigate the next day. We also use ashes of a fire, none of these products are harmful to our health, plants grow better and pests are kept under control using natural products. I have planted Mexican Marigolds because of their different colors and its unpleasant smell which keeps bad insects away so they don’t attack the plants; sunflowers, basil, millet and rosemary are all natural repellents, I also use blue, yellow and white traps. HT: I imagine it’s hard to get a hold of seeds. TR: There is a store that sells them here but they don’t have them a lot of the time or they are bad quality. I’m trying to leave some of my plants which give me seeds like lettuce and runner beans for example. I have 17 crops, six which are currently in production: moringa, tomatoes, lettuce, parsley, oregano, leeks. Sweet potato, corn, cassava, caimito and citrus fruits are growing at the moment. HT: How long do you work in the fields? TR: I work from very early in the morning until 9 AM; and then from 5 PM until it gets dark. My father, brother and children all help me out regularly although I’m the one who does most of the work. I have a lot of love for the earth, plants are living beings and we need to water and care for them. It’s a habit and necessity for me. HT: Does the cooperative help you create optimum working conditions? TR: There aren’t decent conditions for working the land. When my husband left for the United States, I had to face the cruel and hard reality of my situation: I was alone. Everything went downhill from there. My brother spoke to me and told me that we couldn’t lose this piece of land, marabu plants were beginning to take over it. I fell into a severe depression which lasted several months; I wasn’t interested in what had been planted or the future of this land. Between all of us, we began to fix the fence because this was at the time that Hurricanes Gustav and Ike hit and we were left with nothing. We fixed the planting beds, we weeded. Two of my children decided to work with me but they didn’t see any short-term results, you need a lot of patience to harvest. It doesn’t give us enough to get by, just to eat. If you don’t work this land they can take it away from you, it’s in usufruct, it used to be idle land before. HT: You had studied agricuture, but there are some things which you forget, where do you get your information from? TR: I like talking to old people a lot, they haven’t studied very much but they have a lot of experience in farming. They plant using the moon phases, they know when to cut sweet potatoes, how far you need to sow one plant from another. I am also looking for courses, I like to know why you have to sow chicory 90 cm away from the other plant and am not satisfied with a: that’s how all of them are planted. HT: There is an agro-market not far from your house which sells the same products you harvest. Does it harm your business? TR: I try to sell for a little less than agro-market prices. Customers like organic crops, what comes directly out of the earth and doesn’t have chemicals. People know me and know that I am very helpful and that I’m not expensive. Everything I sow has grown under the sun. The organoponico used to have a semi-protected cover* which used to regulate the sun’s rays, but when we were hit by the hurricanes, we lost everything. Our crops all grow directly under the sun and that’s why they need a lot of watering. HT: What do you do in your spare time? TR: I go to the church twice a week; I’m a Jehovah’s Witness. This faith and trust I have in God is what has helped me to persevere. I go to the fields a lot of the time and ask him to give me strength to finish off this work because it doesn’t only depend on me, there’s a lot of work to do and when I get home I have to keep on doing chores here and there. Thank god for my children who help me out a lot. My sons are 27, 23 and 19 years old and my daughter is 16. But I do everything; I don’t believe there is anything that a woman can’t do. source

Credit: © nyul / Fotolia A study of older adults links consumption of a pigment found in leafy greens to the preservation of "crystallized intelligence," the ability to use the skills and knowledge one has acquired over a lifetime. The study is reported in the journal Frontiers in Aging Neuroscience. Lutein (LOO-teen) is one of several plant pigments that humans acquire through the diet, primarily by eating leafy green vegetables, cruciferous vegetables such as broccoli, or egg yolks, said University of Illinois graduate student Marta Zamroziewicz, who led the study with Illinois psychology professor Aron Barbey. Lutein accumulates in the brain, embedding in cell membranes, where it likely plays "a neuroprotective role," she said. "Previous studies have found that a person's lutein status is linked to cognitive performance across the lifespan," Zamroziewicz said. "Research also shows that lutein accumulates in the gray matter of brain regions known to underlie the preservation of cognitive function in healthy brain aging." The study enrolled 122 healthy participants aged 65 to 75 who solved problems and answered questions on a standard test of crystallized intelligence. Researchers also collected blood samples to determine blood serum levels of lutein and imaged participants' brains using MRI to measure the volume of different brain structures. The team focused on parts of the temporal cortex, a brain region that other studies suggest plays a role in the preservation of crystallized intelligence. The researchers found that participants with higher blood serum levels of lutein tended to do better on tests of crystallized intelligence. Serum lutein levels reflect only recent dietary intakes, Zamroziewicz said, but are associated with brain concentrations of lutein in older adults, which reflect long-term dietary intake. Those with higher serum lutein levels also tended to have thicker gray matter in the parahippocampal cortex, a brain region that, like crystallized intelligence, is preserved in healthy aging, the researchers report. "Our analyses revealed that gray-matter volume of the parahippocampal cortex on the right side of the brain accounts for the relationship between lutein and crystallized intelligence," Barbey said. "This offers the first clue as to which brain regions specifically play a role in the preservation of crystallized intelligence, and how factors such as diet may contribute to that relationship." "Our findings do not demonstrate causality," Zamroziewicz said. "We did find that lutein is linked to crystallized intelligence through the parahippocampal cortex." "We can only hypothesize at this point how lutein in the diet affects brain structure," Barbey said. "It may be that it plays an anti-inflammatory role or aids in cell-to-cell signaling. But our finding adds to the evidence suggesting that particular nutrients slow age-related declines in cognition by influencing specific features of brain aging."
