Sean bienvenidos japonistasarqueológicos a una nueva noticia de arqueológica del archipiélago nipón, en esta ocasión hablaremos de el ADN, japonés pero antes de publicar esta noticia, ya hay una previa que sirve como introducción ya hablaremos de esto en un directo de instagram dicho esto comencemos. - Se han descubierto 12 genomas en el ADN, nipón ¿De donde vienen estos genomas?¿Los Ainu tienen algo que ver? Recordemos que japón fue habitada hace 30.000 años, aunque hemos visto que los Ainu llegaron antes, los pueblos que vinieron a japón eran cazadores recolectores(Periodos Jomon, Yayoi, Kofun), seguramente cuando llegaron, se encontraron, a diversidad de pueblos, con los que se fueron mezclando, durante el periodo Yayoi llegaron inmigrantes de china y corea que influenciaran este periodo y kofun(III y VII /300 y el 700 d.C.) - Durante el periodo Jomon la población fue de 1.000 personas durante varios milenios, alrededor del año 15.000 empezó a subir el nivel del mar. Los humanos pasaron por el estrecho de Corea, los restos arqueológicos más antiguos datan de 16.000 a 17.000 años de antigüedad. Hay que recordar, que los Ainu, fueron los primeros en llegar al continente.De todas formas de todo esto haremos un video en directo para aclarar las ideas. - Espero que os haya gustado y nos vemos en próximas publicaciones un cordial saludo. - 日本列島の新しい考古学ニュースへようこそ考古学ジャポニスタ、今回はDNA、日本人について話しますが、このニュースを公開する前に、紹介として役立つ以前のニュースがすでにあり、これについてインスタグラムライブで話します始めましょうと言った。 - 日本のDNAで12のゲノムが発見されましたが、これらのゲノムはどこから来たのですか？ アイヌはそれと関係がありますか？日本には3万年前に人が住んでいたことを思い出してください。アイヌが以前に到着したことはありますが、日本に来た人々は狩猟採集民（縄文、弥生、古墳時代）でした。弥生時代には、この時代と古墳時代に影響を与えた中国と韓国からの移民が到着しました（IIIとVII / 300と700AD） - 縄文時代の人口は数千年で1,000人で、15,000年頃から海面が上昇し始めました。人間は対馬海峡を通過しました。最も古い遺跡は16、000年から17、000年前のものです。アイヌが最初に大陸に到着したことを覚えておく必要があります。 いずれにせよ、アイデアを明確にするために、これらすべてのライブビデオを作成します。 - よろしくお願いします。今後の出版物でお会いしましょう。 - Welcome archeological japonistas to a new archeological news of the Japanese archipelago, this time we will talk about the DNA, Japanese but before publishing this news, there is already a previous one that serves as an introduction and we will talk about this in an instagram live said that let's start. - 12 genomes have been discovered in the DNA, Japan. Where do these genomes come from? Do the Ainu have something to do with it? Let us remember that Japan was inhabited 30,000 years ago, although we have seen that the Ainu arrived before, the peoples who came to Japan were hunter-gatherers (Jomon, Yayoi, Kofun periods), surely when they arrived, they found, a diversity of peoples, with the that were mixed, during the Yayoi period immigrants from China and Korea arrived who influenced this period and kofun (III and VII / 300 and 700 AD) - During the Jomon period the population was 1,000 people for several millennia, around the year 15,000 the sea level began to rise. Humans passed through the Korea Strait, the oldest archaeological remains date from 16,000 to 17,000 years old. It must be remembered that the Ainu were the first to arrive on the continent. In any case, we will make a live video of all this to clarify the ideas. - I hope you liked it and see you in future publications a cordial greeting.
Sean bienvenidos amantes del mundo japonés a una nueva publicación, en este caso voy a dar mi opinión sobre uno de los hallazgos que se han hecho en el país del sol naciente y que tiene que ver con el rostro del niño reconstruido y de cómo la genética se aplica a la arqueología espero que os guste.
-
Antes que nada, el periodo yayoi abarca las siguientes fechas, 300a. C 300 d.C estas fechas son las tradicionales, aunque hay estudios más recientes del siglo IX antes de Cristo desde la península de Kyūshū, pero bueno, eso serán otras publicaciones que realizaré sobre el tema, pero en este caso nos vamos a centrar en este hallazgo este hombre se llama Aoya kamijiro.
-
Fue creado en octubre de 2021, ya que 1998 se encontraron unos restos arqueológicos de más de cien huesos humanos por lo cual es una tarea complicada, pero que nos permite reconstruir las facciones y no solo de la gente prehistórica, sino también de la propia historia como del mundo antiguo y de muchas épocas históricas.
-
Esto se obtiene a raíz de los huesos de los que se pueden extraer pequeñas muestras que son las que nos permitirán, saber si el individuo en cuestión era masculino era femenino y si padecía patologías.
-
Las nuevas tecnologías nos permitirán reconstruir fiel miente de alguna forma u otra el rostro, a la cual parece, ya que esto es un avance muy notable, tanto en la genética como en la arqueología porque podemos reconstruir bastante bien a la gente del pasado no sobre toda la población, que suele estar olvida en un segundo plano.

Espero que os haya gustado que pasen una buena semana.

日本を愛する皆さん、新しい出版物へようこそ。今回は、日出ずる国で行われた、復元された子供の顔と遺伝学に関係する発見の 1 つについて、私の意見を述べたいと思います。考古学にも応用できると思います。
-
まず、弥生時代は以下の300aの年代になります。 西暦 300 年頃 これらの日付は伝統的なものですが、九州半島からは紀元前 9 世紀に関するより最近の研究もありますが、それはまた別の出版物でこのテーマについて行う予定ですが、この場合は次のようにします。この発見に焦点を当ててください この男の名前は青谷神代です。
-
1998年に100体以上の人骨の考古学的遺跡が発見されて以来、この計画は2021年10月に作成された。そのため複雑な作業ではあるが、先史時代の人々の派閥だけでなく、古代世界や歴史上のさまざまな時代からの歴史そのものです。
-
これは骨から得られるもので、少量のサンプルを抽出することで、問題の人物が男性か女性か、また病状を患っていたかどうかを知ることができます。
-
新しいテクノロジーにより、何らかの方法で、その顔に見える顔を忠実に復元できるようになります。これは、遺伝学と考古学の両方において非常に注目に値する進歩です。なぜなら、私たちは過去の人々についてではなく、非常によく復元できるからです。国民全体が、通常は背景に隠れて忘れ去られています。

Welcome lovers of the Japanese world to a new publication, in this case I am going to give my opinion on one of the discoveries that have been made in the country of the rising sun and that has to do with the reconstructed child's face and how genetics It applies to archeology. I hope you like it.
-
First of all, the yayoi period covers the following dates, 300a. C 300 AD These dates are the traditional ones, although there are more recent studies from the 9th century BC from the Kyūshū peninsula, but well, that will be other publications that I will make on the subject, but in this case we are going to focus on this discovery This man's name is Aoya kamijiro.
-
It was created in October 2021, since archaeological remains of more than one hundred human bones were found in 1998, which is why it is a complicated task, but it allows us to reconstruct the factions and not only of the prehistoric people, but also of history itself. as from the ancient world and from many historical periods.
-
This is obtained from the bones from which small samples can be extracted that will allow us to know if the individual in question was male or female and if he suffered from pathologies.
-
New technologies will allow us to faithfully reconstruct the face, in some way or another, to which it appears, since this is a very notable advance, both in genetics and in archeology because we can reconstruct quite well the people of the past not about the entire population, which is usually forgotten in the background.
-
I hope you liked it and have a good week.
Are you perchance working on a comic?
Like this? "🖍" Would love to see one of your oc's!
Fffffffwaah thank you so much~!
Here’s my edgy orphan, Silas, who lives on the streets of London around the 1850′s…ish. He’s half human and half Genecian (a race of shape-shifters, it’s an alternate universe), so he’s often treated as subhuman because of his mixed blood. That’s why he’s pretty…angsty. But if you get past the scowl, he’s just a marshmallow who needs some hugs and love.

Packing for a Journey into the Twilight Zone
Submitted for your consideration: A team of researchers from more than 20 institutions, boarding two research vessels, heading into the ocean’s twilight zone.
The twilight zone is a dimly lit region between 650 and 3300 feet below the surface, where we’re unfolding the mystery of how tiny ocean organisms affect our planet’s climate.
These tiny organisms – called phytoplankton – are plant-like and mostly single-celled. They live in water, taking in carbon dioxide and releasing oxygen.
Two boats, more than 100 researchers from more than 20 partner institutions, and a whole fleet of robotic explorers make up the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) team. We’re learning more about what happens to carbon dioxide after phytoplankton digest it.
The Equipment to Find Phytoplankton
Phytoplankton have predators in the ocean called zooplankton. They absorb the phytoplankton’s carbon, carrying it up the food chain. The EXPORTS mission will focus partly on how that happens in the ocean’s twilight zone, where some zooplankton live. When phytoplankton die, sometimes their bodies sink through the same area. All of this carries carbon dioxide into the ocean’s depths and out of Earth’s atmosphere.
Counting Life
Studying the diversity of these organisms is important to better understand what’s happening to the phytoplankton as they die. Researchers from the Virginia Institute of Marine Science are using a very fine mesh net to sample water at various depths throughout the ocean to count various plankton populations.
Researchers from the University of Rhode Island are bringing the tools to sequence the DNA of phytoplankton and zooplankton to help count these organism populations, getting a closer look at what lives below the ocean’s surface.
Science at 500 Feet
Taking measurements at various depths is important, because phytoplankton, like plants, use sunlight to digest carbon dioxide. That means that phytoplankton at different levels in the ocean absorb and digest carbon differently. We’re bringing a Wirewalker, an instrument that glides up and down along a vertical wire to take in water samples all along its 500-foot long tether.
This journey to the twilight zone will take about thirty days, but we’ll be sending back dispatches from the ships. Follow along as we dive into ocean diversity on our Earth Expeditions blog: https://blogs.nasa.gov/earthexpeditions.

All About That (Nucleic) Base
Studying DNA Aboard the International Space Station
What do astronauts, microbes and plants all have in common? Each relies on DNA – essentially a computer code for living things – to grow and thrive. The microscopic size of DNA, however, can create some big challenges for studying it aboard the International Space Station.
The real question about DNA in space: but why, tho?
Studying DNA in space could lead to a better understanding of microgravity’s impact on living organisms and could also offer ways to identify unknown microbes in spacecraft, humans and the deep space locations we hope to visit one day.
Most Earth-based molecular research equipment is large and requires significant amounts of power to run. Those are two characteristics that can be difficult to support aboard the station, so previous research samples requiring DNA amplification and sequencing had to be stored in space until they could be sent back to Earth aboard a cargo spacecraft, adding to the time required to get results.
Fun science pro tip: amplification means to make lots and lots of copies of a specific section of DNA.
However, all of that has changed in a few short years as we’ve worked to find new solutions for rapid in-flight molecular testing aboard the space station.
“We need[ed] to get machines to be compact, portable, robust, and independent of much power generation to allow for more agile testing in space,” NASA astronaut and molecular biologist Kate Rubins said in a 2016 downlink with the National Institutes of Health.
The result? An advanced suite of tabletop and palm-sized tools including MinION, miniPCR, and Wet-Lab-2, and more tools and processes on the horizon.
The timeline:
Space-based DNA testing took off in 2016 with the Biomolecule Sequencer.
Comprised of the MinION sequencer and a Surface Pro 3 tablet for analysis, the tool was used to sequence DNA in space for the first time with Rubins at the helm.
In 2017, that tool was used again for Genes in Space-3, as NASA astronaut Peggy Whitson collected and tested samples of microbial growth from around the station.
Alongside MinION, astronauts also tested miniPCR, a thermal cycler used to perform the polymerase chain reaction. Together these platforms provided the identification of unknown station microbes for the first time EVER from space.
This year, those testing capabilities translated into an even stronger portfolio of DNA-focused research for the orbiting laboratory’s fast-paced science schedule. For example, miniPCR is being used to test weakened immune systems and DNA alterations as part of a student-designed investigation known as Genes in Space-5.
The study hopes to reveal more about astronaut health and potential stress-related changes to DNA created by spaceflight. Additionally, WetLab-2 facility is a suite of tools aboard the station designed to process biological samples for real-time gene expression analysis.
More tools for filling out the complete molecular studies opportunities on the orbiting laboratory are heading to space soon.
“The mini revolution has begun,” said Sarah Wallace, our principal investigator for the upcoming Biomolecule Extraction and Sequencing Technology (BEST) investigation. “These are very small, efficient tools. We have a nicely equipped molecular lab on station and devices ideally sized for spaceflight.”
BEST is scheduled to launch to the station later this spring and will compare swab-to-sequencer testing of unknown microbes aboard the space station against current culture-based methods.
Fast, reliable sequencing and identification processes could keep explorers safer on missions into deep space. On Earth, these technologies may make genetic research more accessible, affordable and mobile.

The As, Gs, Cs and Ts of the Space Station: First In-Space Microbe Identification
Being able to identify microbes in real-time aboard the International Space Station, without having to send them back to Earth for identification first, would be totally amazing for the world of microbiology and space exploration.
The Genes in Space 3 team turned that possibility into a reality this year, when it completed the first-ever sample-to-sequence process entirely aboard the space station.
The ability to identify microbes in space could aid in the ability to diagnose and treat astronauts in real time, as well as assisting in the identification of life on other planets. It could also benefit other experiments aboard the space station.
HELPFUL SCIENCE HINT: Identifying microbes involves isolating the DNA of samples, and then amplifying – or making lots and lots (and LOTS) of copies - of that DNA that can then be sequenced, or identified.
As part of regular monitoring, petri plates were touched to various surfaces of the space station. NASA astronaut Peggy Whitson transferred cells from growing bacterial colonies on those plates into miniature test tubes, something that had never been done before in space (first OMG moment!).
Once the cells were successfully collected, it was time to isolate the DNA and prepare it for sequencing, enabling the identification of the unknown organisms – another first for space microbiology.
Enter Hurricane Harvey. *thunder booms*
“We started hearing the reports of Hurricane Harvey the week in between Peggy performing the first part of collecting the sample and gearing up for the actual sequencing,” said Sarah Wallace, the project’s primary investigator.
When our Johnson Space Center (JSC) in Houston became inaccessible due hurricane conditions, Marshall Space Flight Center’s Payload Operations Integration Center in Huntsville, Alabama worked to connect Wallace to Whitson using Wallace’s personal cell phone.
With a hurricane wreaking havoc outside, Wallace and Whitson set out to make history.
The data were downlinked to the team in Houston for analysis and identification.
“Once we actually got the data on the ground we were able to turn it around and start analyzing it,” said Aaron Burton, the project’s co-investigator. “You get all these squiggle plots and you have to turn that into As, Gs, Cs and Ts.”
Those As, Gs, Cs and Ts are more than just a nerdy alphabet – they are Adenine, Guanine, Cytosine and Thymine – the four bases that make up each strand of DNA and can tell you what organism the strand of DNA came from.
“Right away, we saw one microorganism pop up, and then a second one, and they were things that we find all the time on the space station,” said Wallace. “The validation of these results would be when we got the sample back to test on Earth.”
Soon after, the samples returned to Earth aboard the Soyuz spacecraft, along with Whitson.
With the samples now in the team’s JSC lab, tests were completed in ground labs to confirm the findings from the space station. They ran the tests again and again, and then once more, to confirm accuracy. Each time, the results were exactly the same on the ground as in orbit. (second OMG moment!)
“We did it. Everything worked perfectly,” said Sarah Stahl, microbiologist.
This capability could change future space exploration.
“As a microbiologist,” said Wallace, “My goal is really so that when we go and we move beyond ISS and we’re headed towards Mars or the moon or wherever we are headed to, we have a process that the crew can have that great understanding of the environment, based on molecular technology.”

Why Sequencing DNA in Space is a Big Deal
... And How You Can Talk to the Scientists Who Made It Happen
Less than one month ago, DNA had never been sequenced in space. As of today, more than one billion base pairs of DNA have been sequenced aboard the International Space Station, Earth’s only orbiting laboratory. The ability to sequence the DNA of living organisms in space opens a whole new world of scientific and medical possibilities. Scientists consider it a game changer.
NASA astronaut Kate Rubins, who has a background in genomics, conducted the sequencing on the space station as part of the Biomolecule Sequencer investigation. A small, commercial, off-the-shelf device called MinION (min-EYE-ON), manufactured by Oxford Nanopore Technologies in the UK, was used to sequence the DNA of bacteria, a virus and rodents. Human DNA was not sequenced, and there are no immediate plans to sequence human DNA in space.

The MinION is about the size of a candy bar, and plugs into a laptop or tablet via USB connection, which also provides power to the device. The tiny, plug and play sequencer is diminutive compared to the large microwave-sized sequencers used on Earth, and uses much less power. Unlike other terrestrial instruments whose sequencing run times can take days, this device’s data is available in near real time; analysis can begin within 10-15 minutes from the application of the sample.
Having real-time analysis capabilities aboard the space station could allow crews to identify microbes, diagnose infectious disease and collect genomic and genetic data concerning crew health, without having to wait long periods of time to return samples to Earth and await ground-based analysis.
The first DNA sequencing was conducted on Aug. 26, and on Sept. 14, Rubins and the team of scientists back at NASA’s Johnson Space Center in Houston hit the one-billionth-base-pairs-of-DNA-sequenced mark.
