Science and Education: Genome Brings Ancient Girl to Life

Old news (2012).  But still interesting.  Scientists have reached across millennia to reconstruct the face of a girl who lived thousands of years ago—using nothing but fragments of her DNA.

In a stunning technical feat, an international team of scientists has sequenced the genome of an archaic Siberian girl 31 times over, using a new method that amplifies single strands of DNA. The sequencing is so complete that researchers have as sharp a picture of this ancient genome as they would of a living person's, revealing, for example, that the girl had brown eyes, hair, and skin. . . .

  • A 200,000-year-old 'baby tooth' reveals clues about mysterious human lineage(nationalpost.com) - A 200,000‑year‑old baby tooth discovered in Laos has revealed genetic traces of a previously unknown human lineage, showing that ancient populations in Southeast Asia were far more diverse and interconnected than scientists once believed. The find helps bridge gaps between Denisovans and other early humans in the region. Denisovans were an extinct group of archaic humans closely related to Neanderthals and modern Homo sapiens. They lived across Asia tens of thousands of years ago
  • Harvard geneticist hoping herd mentality hits Woolly research(bostonherald.com) - Harvard geneticist George Church is working to revive woolly mammoth traits in modern elephants, hoping that public enthusiasm—and funding—will help push the research forward. The project aims to create cold‑resistant “mammophants” that could help restore Arctic ecosystems and slow permafrost melt.
  • How Much Should You Trust Your DNA Test?(newsy.com) - At‑home DNA ancestry tests are under scrutiny as scientists argue they can oversimplify heritage, misinterpret genetic signals, and give consumers a false sense of precision. Experts say the tests can be fun and informative, but their accuracy varies widely, and results should be viewed as broad estimates rather than definitive family histories.
  • We made a minimal cell and began a synthetic-life revolution (aeon.co) - Scientists at the J. Craig Venter Institute created a “minimal cell” containing only the genes essential for life, revealing how streamlined genomes behave and opening the door to a new era of synthetic biology. The work shows that even the simplest engineered organism can display unexpected complexity, reshaping our understanding of what life fundamentally requires.
  • How will genomics enter day-to-day medicine? (sciencedaily.com) - Researchers discovered that ancient DNA can survive far longer than expected, even in harsh environments, after successfully recovering genetic material from 8,000‑year‑old human remains in the Sahara. The findings show that early North African populations were genetically diverse and connected to groups across both the Middle East and sub‑Saharan Africa.
  • Genome Instability May Be Linked To Schizophrenia (asianscientist.com) - Researchers found that people with schizophrenia show signs of genome instability, meaning their DNA accumulates more mutations than usual, which may contribute to the disorder’s development. The study suggests that disrupted genetic maintenance could be a key biological factor behind schizophrenia.
  • DNA tests can't prove racial ancestry (amanwithaphd.wordpress.com) - Geneticists argue that consumer DNA tests cannot reliably determine racial ancestry because race is a social category, not a precise genetic one. While DNA can reveal broad population affinities, it cannot map neatly onto racial labels or provide definitive identity claims.
SO?  Race doesn't exactly align with genetics?
****
I'm not a scientist, but I have some thoughts about all of this.


ATTN: Calling All Geneticists!
Here is a question that is driving me nuts! I don't know enough about the science of genetics, and I watch way too many movies, which causes a problem for me when it comes to distinguishing fact from fiction. Watched a James Bond movie, and one of the characters had undergone genetic therapy in Cuba. More specifically, he had undergone DNA replacement therapy that changed him into a completely different person. Are you a wanted criminal? Well, forget about plastic surgery. DNA replacement is the way to go! OK. Here's the problem I have with that. Suppose you were doing research on your family tree? Do you watch that PBS program "Finding Your Roots with Henry Louis Gates Jr." where he traces the ancestry of celebrities? He does the ancestry research two ways: via the records and documents available and via a DNA test. ( pbs.org/weta/finding-your-roots/about/ ) Suppose one of your ancestors underwent gene replacement therapy? The guy in James Bond went from being North Korean to being British!! Doesn't that sort of blow a hole in the validity of the whole DNA testing thingamabob to trace your ancestry?? It's a valid question. Especially considering the significant impact the response could also on have on crime solving.

One World - Multiple Space Colonies (Happy Earth Day!)

There's a trend in the world of science and space exploration towards colonizing other planets. We all know the motivation behind this. Uh huh.

Mankind is screwing up planet earth; so people are looking and hoping to build a new community in another part of the universe.

To quote Homer Simpson: “Doh!”

As if … we humans won't do the exact same thing if we set up shop elsewhere!



Oh, it will start off all good, just like planet earth did. But there will be one thing wrong with the new world on Mars, Venus, Jupiter, wherever.

There will still be humans living there.

Humans with the same mindset in the new space colony that they had when they lived on planet earth.

Give it some time. Before you know it, someone will pop the question.

Uuummm … how come we don't have a red button?

10 Hackers Who Drastically Changed the World (Reblog)

#1 is Julian Assange ... #10 is Anonymous

"Yes, literally. While hacking is as amoral as science or mathematics, and therefore couldn't possibly be morally wrong, it is indeed literally wrong. Hacking, in the broadest sense of the word, is to attempt to interact with a system (any system) in a clever, innovative, and challenging way that the system was not intended to be interacted with, or the wrong way."

Women in Science : Give Credit When Due

Celebrating Women's History Month.


There's a scripture that says we should "give credit where credit is due, and give honor to whom honor is due".  Don't know why, but it's easy to laud this principle and very difficult to apply it to real life situations. Anyway ... I don't think any of these women are bitter.  They probably consider that they were blessed to have the avenues and opportunities to use their talents and gifts for the greater good.  Women are like that.  Yeah they are!

Ever heard of any of these women? I hadn't until I came across these interesting BIO snapshots.

- Émilie du Châtelet, Mathematician

- Julia Morgan, Architect

- Rosalind Franklin, Biophysicist

Interesting tidbit:
  • Emilie du Chatelet was named Gabrielle-Emilie; however, friends in her circle which included Voltaire {Francois-Marie Arouet (1694 - 1778), who later took the name of Voltaire} dropped Gabrielle and just called her Emilie. Her husband's name was the Marquis du Chastellet. But because Voltaire called her du Chatelet, everyone else did too!  [Click the embedded link her name above to read more.]

Celebrating the Genius of Einstein and #GR101

Started scanning a tweet stream this morning and found out that folks were celebrating the 101st anniversary of Einstein's Theory of General Relativity.  Collecting quotes is my hobby and in particular, always like to read what Albert Einstein (1879 - 1955) had to say.  Plucked this one from the Twitter feed.  It was shared by George Shiber.  (See embedded tweet below.)


https://twitter.com/GeorgeShiber/status/793608381613350912

Mr. Einstein died the year I was born.  It's not like we would have ever been best buds, but I fancy myself sometimes having a conversation with him.  Were we having a tête-à-tête, my response to his statement above would be:

"Not even a genius like you, Mr. Einstein, can comprehend all of God's thoughts. But if a fool would desire to understand just one of God's thoughts, they'd come out ahead.  (Wink. Wink.)"

Einstein always acknowledged The One Who gave him his brilliant mind.  That's what I most admired about him.

Who is the most intelligent person in the world's history? - Quora.com

From time to time I check Quora.com for their interesting Q&As. Like this question:

Who is the most intelligent person in the world's history?



Varied responses to this question that basically range from responders indicating: (a) naming names of historical people; (b) debating the validity and validation of the "IQ score" and (c) pretty much saying it's a dumb question!
