    Who’s More Irish, You or Your Sibling?
    The Surprising Science Behind the Inheritance of Ethnicity
    ...
    Take a look:

    Do you see what happened? My oldest sister’s ethnicity results (on the far left), show she’s 45% Irish.
    Mine show I’m just 22% Irish. So my sister is twice as Irish as I am!
    And my other two siblings were right around 30% Irish. That means, despite my birthday, I’m actually the least Irish.
    ...
    All three of my sisters received a good portion of ethnicity from Europe West — and I basically got none.
    In the first moment I almost felt robbed. But then I realized my ethnic mix is just different but every bit as awesome.
    I am, for example, the most British (cue British accent and Britishisms like “Bob’s your uncle”).
    How Can This Happen?

    We all get 50% of our DNA from each of our parents. But they don’t give each kid the same 50% — unless you’re identical twins.
    So it’s not super unusual for siblings to have different percentages of their parents’ ethnicities.
    It makes sense if you think about the science behind it. But the first time most of us learn that our siblings can be more Irish or have DNA from a region that we totally lack, it’s definitely mind blowing.

    Humans have another type of DNA inside our cells
    ...
    Scientists have identified an entirely new kind of DNA inside humans.
    This new DNA, known as the “i-motif,” was suggested in previous research, but had only been identified under artificial conditions in a lab. But research published in Nature Chemistry is the first study to confirm its existence inside living beings.
    The i-motif looks like a twisted knot, as opposed to DNA’s well-known double helix structure.

    In a double helix strand of DNA, there are four compounds that form “bases” — adenine, thymine, cytosine and guanine. Adenine typically binds with thymine while the cytosine binds with guanine, but this isn’t the case in the i-motif.
    “The i-motif is a four-stranded ‘knot’ of DNA,” Marcel Dinger, a co-author on the study, said in a press release. “In the knot structure, C [cytosine] letters on the same strand of DNA bind to each other – so this is very different from a double helix, where ‘letters’ on opposite strands recognize each other and where Cs bind to Gs [guanines].”

    To find the i-motifs, the scientists engineered antibodies into tiny probes that would attach themselves only to i-motifs. They added fluorescent dye to the probes so they could track exactly where the i-motifs were.
    These antibody probes were then placed in three variations of human cells where scientiests had hoped to identify the i-motifs in the nucleus of each cell.
    More research is needed to determine the i-motif’s purpose, but the researchers believe the structures help to switch genes “on or off.”

    Variant to #122 above;
    If we weren’t the first industrial civilization on Earth, would we ever know?

    Fossils and objects are unlikely to survive more than a few million years. Searching for chemical traces of industrialization offers an intriguing alternative.

    Rare Mutation Among Bajau People Lets Them Stay Underwater Longer

    The Bajau people of Malaysia and the Philippines are renowned for their free-diving abilities, often working eight-hour shifts in search of fish and other sea critters. Underwater sessions can last upwards of two minutes, with accumulated daily totals of breath-holding often reaching five hours. New research suggests these impressive feats aren’t the result of training, but rather, an example of natural selection at work—which, in this case, has endowed Bajau individuals with abnormally large spleens.

    The Bajau are a small community from Southeast Asia, living in Malaysia, the Sulu Archipelago in the Philippines, Mindanao, Borneo, and the eastern Indonesian islands. Some pockets of Bajau still live a traditional lifestyle, living in houseboats or wooden huts propped over the water on wooden stilts. Often referred to as “sea nomads,” the Bajau are formidable free divers who have engaged in breath-hold diving for thousands of years. Today, Bajau free divers use rudimentary equipment, like masks and a spears, while searching for fish, lobster, and octopus.

    Was There a Civilization On Earth Before Humans?
    A look at the available evidence
    ...
    We never got back to aliens. Instead, that first conversation launched a new study we’ve recently published in the International Journal of Astrobiology. Though neither of us could see it at that moment, Gavin’s penetrating question opened a window not just onto Earth’s past, but also onto our own future.

    We’re used to imagining extinct civilizations in terms of the sunken statues and subterranean ruins. These kinds of artifacts of previous societies are fine if you’re only interested in timescales of a few thousands of years. But once you roll the clock back to tens of millions or hundreds of millions of years, things get more complicated.

    When it comes to direct evidence of an industrial civilization—things like cities, factories, and roads—the geologic record doesn’t go back past what’s called the Quaternary period 2.6 million years ago. For example, the oldest large-scale stretch of ancient surface lies in the Negev Desert. It’s “just” 1.8 million years old—older surfaces are mostly visible in cross section via something like a cliff face or rock cuts. Go back much farther than the Quaternary and everything has been turned over and crushed to dust.

    And, if we’re going back this far, we’re not talking about human civilizations anymore. Homo sapiens didn’t make their appearance on the planet until just 300,000 years or so ago. That means the question shifts to other species, which is why Gavin called the idea the Silurian hypothesis, after an old Dr. Who episode with intelligent reptiles.

    So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.

    Given that all direct evidence would be long gone after many millions of years, what kinds of evidence might then still exist? The best way to answer this question is to figure out what evidence we’d leave behind if human civilization collapsed at its current stage of development.

    What Did the Ancients See? Unidentified Flying Objects that Made an Impact on Early History
    ...
    The number of reported UFO sightings has hit an all time high in 2017. In the 112(*) years since the National UFO Reporting Center began keeping track, there have been 104,947 reported events (Monfort, 2017). The majority of sightings occur in the United States, though Canada, Australia, and the Nordic countries also have significant numbers of unidentified flying object sightings. Most of these incidents can be explained – airplanes, satellites, comets, fireworks (there is a spike in reported sightings in the US each year around the Fourth of July) – and many people write off UFO-spotters as fanatics.
    Unidentified Flying Objects Seen in Ancient Egypt

    Yet, the phenomenon of unidentified flying objects stretches further back in history than the 1950s ‘flying saucer’ reports. In fact, the oldest recorded sighting of an unidentified flying object took place in 1440 BC. The incident was documented by the royal scribe of an Egyptian Pharaoh. Before the modern-era, UFOs were also recorded by ancient Greeks, Romans, Indians, Chinese, Japanese, Mexicans, and more. These sightings cannot be as readily explained as airplanes or fireworks.

    With nova/supernova a main premise here, this article is of interest and related;
    Ancient supernova is oldest and most distant found
    https://www.newscientist.com/article...distant-found/

    The photo suggests that these type explosions are not uniformly spherical and symmetrical;

    A massive star that exploded when the universe was just 3 billion years old has been found. It is classified as a type IIn supernova, which is caused by a star that belches out large quantities of gas before its final explosion. The fitful Milky Way star Eta Carinae (above) jettisoned the twin Homunculus clouds in 1843 and is expected to meet its end as a type IIn supernova(Image: Jon Morse/University of Colorado/NASA)

    Oldest Human DNA from Africa Reveals Clues About a Mysterious Ancient Culture
    ...
    Burials from a cave in Morocco have yielded the oldest human DNA evidence yet from Africa, offering new insight into Stone Age migrations.

    The DNA samples come from one of the most ancient cemeteries in the world, the Grotte des Pigeons, near the village of Taforalt in northeast Morocco.

    Beginning around 15,000 years ago, a culture of hunter-gatherers buried their dead with animal horns and other adornments inside this cave. Though burials were found as recently as 2006, archaeologists have been excavating the cave since the 1940s. [Image Gallery: Our Closest Human Ancestor]
    ...
    But the new DNA evidence tells a different story about the origins of the Iberomaurusians. During recent excavations led by the University of Oxford at the Grotte des Pigeons, archaeologists saved the inner-ear petrous bones, a good source for ancient DNA. Researchers at the Max Planck Institute for the Science of Human History, in Jena, Germany, extracted ancient mitochondrial DNA, which is passed on only from mothers to their children, from seven individuals, as well as nuclear DNA, which is inherited from both parents, from five of the skeletons.

    "Due to challenging conditions for DNA preservation, relatively few ancient genomes have been recovered from Africa, and none of them so far predate the introduction of agriculture in North Africa," Marieke van de Loosdrecht, an archaeogeneticist at the Max Planck Institute for the Science of Human History, said in a statement.

    Contrary to the theory that Europeans from Sicily or the Iberian Peninsula were buried at Grotte des Pigeons, the analysis revealed no genetic link to southern Europe. Instead, the results, which were reported March 15 in the journal Science, showed that about two-thirds of the Iberomaurusian DNA matched closely with that of ancient Natufians, a later culture that existed in the Middle East, which suggests the Grotte des Pigeons people and the Natufians shared common ancestors from North Africa or the Middle East.

    Actually, I think we got much of that once we were created with half our nucleic DNA coming from the Anunnaki. Part of the number eleven below, over 4,000 genetic disorders.

    12 ways in which humans are NOT Primates
    1) BONES - much thinner and lighter
    2) MUSCLES - 5 to 10 times weaker
    3) SKIN - not well adapted to direct sunlight
    4) ADIPOSE TISSUE - 10 times as much
    5) BODY HAIR - Missing, pattern reversed
    6) HEAD HAIR AND NAILS - Must be trimmed
    7) SKULLS & BRAINS - Not in same ball park
    8) LOCOMOTION - Most obvious difference
    9) SPEECH - Throats completely redesigned
    10) SEX - No sign of typical oestrus cycles
    11) GENETIC DISORDERS - Over 4,000 !!!
    12) CHROMOSOMES - Reduced from 48 to 46

    Numbers 3,4,5,6,&8 above could be "Aquatic Ape" traits that were part of the Anunnaki evolutionary past, passed onto us in the 'splice'.

    Human Eggs Grown In The Lab In World First
    ....
    Scientists have created mature human eggs in the lab for the first time.
    The breakthrough could eventually help women preserve their fertility after cancer treatment, or help those with naturally occurring infertility.

    To create the eggs, a team led by Marie McLaughlin at the University of Edinburgh first took ovarian biopsies from women undergoing elective cesareans. This tissue was then dissected into thin strips, each containing many follicles.

    Women are born with millions of follicles, but the number decreases to about 400,000 by puberty. Each month after puberty, several follicles begin to develop with one eventually releasing a mature egg capable of being fertilized.

    The follicles in the experiment were cultured in a dish for eight days. At the end of this period, follicles that had developed correctly were dissected from the strips and put in another culture where they were left to grow in the presence of growth factors. Eight days later, early stage eggs were retrieved from the follicles and grown in the presence of further growth factors and a hormone called FSH. This process led to the development of several mature eggs.
