Using Asteroids To Further Humanity
Jun 28 2018 35 mins  
In 2013 NASA introduced an asteroid-capture mission called ARM (Asteroid Redirect Mission) which would bring an asteroid to moon's orbit. ____________________ Sources: The Evolution Of NASA’s Ambitious Asteroid-Capture Mission: https://www.space.com/28963-nasa-asteroid-capture-mission-history.html “NASA's ambitious asteroid-capture mission has changed a lot since the agency officially announced its existence less than two years ago. The original plan, which was revealed in April 2013, called for dragging an intact small space rock into orbit around the moon, where it would be visited by astronauts, perhaps as early as 2021." Animation Of Proposed Asteroid Retrieval Mission Video: https://www.youtube.com/user/VideoFromSpace “NASA's 2014 budget poposes a mission to robotically capture a small near-Earth asteroid and bring it into a stable lunar orbit where astronauts can visit and explore it, a 'stepping stone' to future missions to farther asteroids." Asteroid Retrieval Feasibility Study: https://www.rt.com/usa/158784-nasa-asteroid-landing-mining/ “This report describes the results of a study sponsored by the Keck Institute for Space Studies (KISS) to investigate the feasibility of identifying, robotically capturing, and returning an entire Near-Earth Asteroid (NEA) to the vicinity of the Earth by the middle of the next decade." NASA Aims To Land On, Capture Asteroids Within Next 15 Years: https://www.rt.com/usa/158784-nasa-as... “NASA researchers are at work developing a plan that not only hopes to physically place astronauts on an asteroid for the first time, but also to wrangle a space object and place it in the orbit of the Earth’s moon."

"Gene" is a general word for a piece of DNA that creates proteins, but what exactly are genes? Why do they matter? ____________________ Sources: DNA can't explain all inherited biological traits, research shows https://www.sciencedaily.com/releases/2015/04/150402161751.htm "Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on." Rosalind Franklin: Biography & Discovery of DNA Structure? https://www.livescience.com/39804-rosalind-franklin.html "Many people recall that the structure of the DNA molecule has the shape of a double helix." What Are Proteins And What Do They Do? https://ghr.nlm.nih.gov/primer#howgeneswork "Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs." ____________________ Follow Trace on twitter: http://twitter.com/tracedominguez Follow Seeker on twitter: http://twitter.com/seeker And, subscribe on YouTube too: http://youtube.com/seeker Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

Ocean acidification, over-fishing, warming climate and other environmental triggers may spell the next "Great Dying," but are we there yet? ____________________ Sources: Early Accretion Of Water In The Inner Solar System From A Carbonaceous Chondrite-like Source: http://science.sciencemag.org/content/346/6209/623 “Determining the origin of water and the timing of its accretion within the inner solar system is important for understanding the dynamics of planet formation." Dehydration Melting At The Top Of The Lower Mantle: http://science.sciencemag.org/content/344/6189/1265 “The high water storage capacity of minerals in Earth’s mantle transition zone (410- to 660-kilometer depth) implies the possibility of a deep H2O reservoir, which could cause dehydration melting of vertically flowing mantle." Why Do We Look For Water When Searching For Extraterrestrial Life?: https://io9.gizmodo.com/5728932/why-do-we-look-for-water-when-searching-for-extraterrestrial-life “The assumption that alien biochemistries probably require liquid water may seem a little Earth-centric. But given the chemical possibilities available from the most abundant elements in the universe, even an alien scientist with a different biochemistry would probably agree that a water-solvent-based biochemistry is quite likely to occur elsewhere in the universe – and might well be the most likely foundation for a complex ecosystem in which intelligent life could develop." Scientists Discover The Oldest, Largest Body Of Water In Existence — In Space: https://www.fastcompany.com/1769468/scientists-discover-oldest-largest-body-water-existence-space “Scientists have found the biggest and oldest reservoir of water ever—so large and so old, it’s almost impossible to describe. The water is out in space, a place we used to think of as desolate and desert dry, but it's turning out to be pretty lush." ____________________ Follow Trace on twitter: http://twitter.com/tracedominguez Follow Seeker on twitter: http://twitter.com/seeker And, subscribe on YouTube too: http://youtube.com/seeker Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

We've all learned it takes 24 hours for the Earth to rotate once on its axis but that isn't the whole story at all. There's much more to it. ____________________ Sources: Why Are There 24 Hours In A Day?: http://www.abc.net.au/science/articles/2011/11/15/3364432.htm “While each country has (in broad terms) historically had distinct measurements for distance, weights etc the method of splitting the day into 24 hours, one hour into 60 mins and one minute into 60 seconds seems to be the only one in use, and indeed to me the only one I know of. " Keeping Time: Why 60 Minutes?: https://www.livescience.com/44964-why-60-minutes-in-an-hour.html “How did we come to divide the hour into 60 minutes and the minute into 60 seconds? These smaller divisions of time have been in practical use for only about 400 years, but they were vital to the advent of modern science." Why Is A Minute Divided Into 60 Seconds, An Hour Into 60 Minutes, Yet There Are Only 24 Hours In A Day?: https://www.scientificamerican.com/article/experts-time-division-days-hours-minutes/ “In today's world, the most widely used numeral system is decimal (base 10), a system that probably originated because it made it easy for humans to count using their fingers." ____________________ Follow Trace on twitter: http://twitter.com/tracedominguez Follow Seeker on twitter: http://twitter.com/seeker And, subscribe on YouTube too: http://youtube.com/seeker Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

The History And Ethics Of Propaganda
Mar 08 2018 34 mins  
It's a common goal of propaganda to promote a biased opinion, and while many may resist, propaganda actually has the ability to save lives! ____________________ Sources: A Very Brief History of Propaganda in Times Past: https://www.physics.smu.edu/pseudo/Propaganda/history.html "Propaganda has been around for a long time, going back to ancient Greece. Chapter 2 of Jowett & O'Donnell provides an excellent historical background. In there you will find numerous examples of historical propaganda campaigns. " The Story of Propaganda: https://www.historians.org/about-aha-and-membership/aha-history-and-archives/gi-roundtable-series/pamphlets/what-is-propaganda/the-story-of-propaganda "The American Historical Association produced the G.I. Roundtable Series to help win World War II. Or so they were led to believe. In fact the U.S. Army sought the pamphlets as part of a larger effort to prepare for the transition to the postwar world, and represent a novel effort at social control." From stamps to social media, the history of propaganda: https://www.thenational.ae/arts-culture/from-stamps-to-social-media-the-history-of-propaganda-1.303748 "Since the twentieth century, propaganda has largely had pejorative associations. The term continues to imply something sinister; synonyms for propaganda frequently include lies, falsehood, deceit, and brainwashing." Here's some incredible pro-independence propaganda from the American Revolution: http://www.businessinsider.com/pro-independence-propaganda-from-the-american-revolution-2015-7 "During the Revolutionary War, Benjamin Franklin and Paul Revere were among the people who created stunning pieces of art that inspired the fight for America's independence." House of Bourbon: https://www.britannica.com/topic/house-of-Bourbon "House of Bourbon, Spanish Borbón, Italian Borbone, one of the most important ruling houses of Europe.

The cathode tube was a prime example, no one knew how it worked. Some thought the rays were a wave traveling through a mysterious "ether" which they thought permeated all space.” Who was Democritus? https://www.universetoday.com/60058/democritus-atom/ “One such person is Democritus, an ancient Greek philosopher who is viewed by many as being the ‘father of modern science.’ This is due to his theory of universe that is made up of tiny ‘atoms’, which bears a striking resemblance to modern atomic theory.” Thales of Miletus http://www.iep.utm.edu/thales/ “The ancient Greek philosopher Thales was born in Miletus in Greek Ionia. Aristotle, the major source for Thales's philosophy and science, identified Thales as the first person to investigate the basic principles, the question of the originating substances of matter and, therefore, as the founder of the school of natural philosophy.” ____________________ Follow Trace on twitter: http://twitter.com/tracedominguez Follow Seeker on twitter: http://twitter.com/seeker And, subscribe on YouTube too: http://youtube.com/seeker Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

These muscles are used for extended periods of activity, such as standing or walking, and need a consistent energy source.” Will Meatless Meat Be The Future Of Food? https://www.seeker.com/will-meatless-meat-be-the-future-of-food-1968210074.html “Books, TV and film have given us many concepts of futuristic food over the years. Perhaps a pill that makes you full without having to eat anything else, or various liquid concoctions full of essential vitamins and minerals. In reality, the near future of food, particularly meat, actually looks... a lot like the meat we eat today, but for one major difference: it’s grown inside a lab.” Organic Farming Could Feed the World, but Only If People Consume Less Meat https://www.seeker.com/earth/organic-farming-could-feed-the-world-but-only-if-people-consume-less-meat “Arguments have rung hollow among those who question whether farmers can grow enough organic food to feed the world’s growing population without the help of science. Writing in the journal Nature Communications, however, scientists conclude that organic agriculture could feed everybody on the planet if people wasted less food and ate less meat.” Will Fake Meat Ever Be As Good As Real Meat? https://www.thrillist.com/eat/nation/veggie-burgers-fake-meat-substiutes-vs-real-investigation “Today in America we kill over 9 billion food animals per year. Raising animals for food consumes half of all water used in this country, and three-quarters of all our grain. By some estimates, food animals produce more greenhouse gasses than every last airplane, train, car, bus, boat, and truck on Earth.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.
