Footprints in Ancient Ash

Image
Scientists are pretty sure that Saccorhytus coronarius is an ancestor of lancets, sea squirts, fish, amphibians, reptiles, dinosaurs, and mammals: including us. Much more recently, about 3,660,000 years back, five Australopithecus afarensis strolled across volcanic ash. One of them was "astonishingly larger" than any other A. afarensis we know of. Exactly what that means isn't, I think, clear. Not yet. More at A Catholic Citizen in America .

Making a Universe: Why Bother?

Image
"The heavens declare the glory of God; the sky proclaims its builder's craft." ( Psalms 19:2 ) Okay, so who is this message proclaimed to? Us, apparently. One of the ways we can learn about God is by noticing order and beauty in the universe. (Catechism of the Catholic Church, 31 - 32 , 319 ) St. Bonaventure said that the universe communicates God's glory, St. Thomas Aquinas said that the Almighty creates because God is good and loving. (Catechism, 293 ) I think they're right. More at A Catholic Citizen in America .

Gems, Metal, and Earth's Core

Image
The Fire of Australia, a whacking great chunk of opal, isn't particularly interesting from a 'science' viewpoint. But I'm human, which is probably why anything big and shiny gets my attention: including that rock. Wrenching myself back on-topic, scientists found a stream of liquid metal flowing at the edge of Earth's core. Studying it may help us learn why Earth's magnetic field flip-flops at apparently-irregular intervals. What we'll learn is beyond me: we didn't know much about geomagnetic reversal when I started school. We still don't, for that matter. As I keep saying, there is a very great deal left to learn.

Urban Evolution and Big Brains

Image
Life, and evolution, has been happening for quite a while. Cities are new, but the same processes happen there; with slightly different results. We're learning how urban environments affect critters, and are piecing together more of humanity's story.... ...I see no problem with believing that God is creating a universe that's following knowable physical laws. That's just as well, since it's what we're told to believe.... More at A Catholic Citizen in America .

Epiphany Sunday

Image
Statues 1 of Caspar , Melchior , and Balthazar started near the clock in our living room. I took those pictures of them on Wednesday. Their trip to the nativity scene ended today, Epiphany Sunday. We read about "magi from the east" in today's Gospel: Matthew 2:1 through 12 : " 1 When Jesus was born in Bethlehem of Judea, in the days of King Herod, 2 behold, magi from the east arrived in Jerusalem, "saying, 'Where is the newborn king of the Jews? We saw his star 3 at its rising and have come to do him homage.'" ( Matthew 2:1 - 2 ) "Magi" is how μάγοι, mágoi, looks in my native language. That's the Greek version of an Old Persian word that would sound something like "magus" if I tried pronouncing it. More at A Catholic Citizen in America .

SETI: What If?

Image
Contacting extraterrestrial intelligence, meeting people whose ancestors developed on another world, has been a staple of pulp fiction for generations. Lately, it's become a matter for serious discussion. I'll be looking at an op-ed's take on how learning that we're not alone might affect folks with various religious beliefs. I'll also share what I expect: and what I don't.... More at A Catholic Citizen in America .

Mars, Aliens, and SETI

Image
I'd love to be talking about unambiguously artificial signals picked up by the Allen Telescope Array , or reports of a ship from beyond the Solar System settling into orbit around our moon. But that hasn't happened, and probably won't. Not in my lifetime. Instead, I'll talk about why I don't "believe in" extraterrestrial life; and do not assume that we are alone in the universe. That puts me in the third of folks who aren't sure, and I'll get back to that. My 'Friday' posts are usually about more-or-less-current 'science news.' That won't happen this week. I've read a few interesting articles, and will be talking about them — after the Christmas-New Year's gymkhana is over. This week I'm using material that didn't quite fit into an earlier post. I'll also talk about the Great Moon Hoax, Nicola Tesla and Martians; and what I think about life in the universe. More at A Catholic Citizen in America .

Jesus and Expectations

Image
Pip's Christmas doesn't have much to do with Christmas, or Advent, but I figured this post should have something that looks 'seasonal.' "...Blessed is the One Who Takes No Offense at Me" We'll be hearing Matthew 11:2 - 11 this morning. The readings still aren't particularly 'Christmassy.' " 2 When John heard in prison 3 of the works of the Messiah, he sent his disciples to him " 4 with this question, 'Are you the one who is to come, or should we look for another?' "Jesus said to them in reply, 'Go and tell John what you hear and see: " 5 the blind regain their sight, the lame walk, lepers are cleansed, the deaf hear, the dead are raised, and the poor have the good news proclaimed to them. "And blessed is the one who takes no offense at me.' " ( Matthew 11:4 - 6 ) Our Lord balanced that rebuke with a reminder of the Baptist's great function in Matthew 11:7 - 15 , and a complai

Tides and Our Moon’s Origin

Image
Scientists have been wondering how our moon formed, and why its orbit isn't over Earth's equator. It looks like our moon formed after something about the size of Mars hit Earth, roughly 4,500,000,000 years back. But the giant-impact hypothesis didn't explain why our moon orbits Earth only five degrees away from Earth's orbital plane. The math had said that our moon would be orbiting pretty much over Earth's equator.... ...God is Large and In Charge I occasionally wonder if I should keep explaining why reality doesn't offend me, and why facts don’t threaten my faith....

KIC 8462852 and Strange Stars

Image
KIC 8462852, Tabby's Star, has been in the news recently. Scientists are pretty sure that something very large orbits the star, but haven't worked out what it is. A few scientists, looking at the data, say that it's probably a really odd natural phenomenon: but that it might something built by folks who aren't human. SETI, the Search for Extraterrestrial Intelligence, is still a science in search of a subject. But quite a few scientists are taking it seriously, which is why Berkeley SETI Research Center added few stars to the Automated Planet Finder's observing queue.... ...What I say about SETI and science in general may take some explaining, if you're new to this blog. Basically, I think God is large and in charge; and that part of my job is appreciating God's work — not telling the Almighty how it should have been made...." More at A Catholic Citizen in America .

Olive Threat, Ginkgo Genome

Image
Something's killing Europe's olive trees: a bacterium that's probably spread by insects. Scientists don't know how to stop the disease, not yet. Other scientists analyzed the Ginkgo genome. What they found helps explain the tree's remarkable endurance. More at A Catholic Citizen in America .

Brain Implants and Rewired Monkeys

Image
Someone from the Netherlands gained a small measure of freedom after learning to use a prototype computer-brain interface. I see that, and experiments with rhesus monkeys, as a good thing.... ...As usual, I'll also talk about why I don't think God is offended when we help folks....

Near-Earth Asteroids

Image
Scientists spotted 2016 UR36 days before it passed by Earth. "Killer asteroids" headlines notwithstanding, we knew it would miss our planet by a comfortable margin. Sooner or later, though, something big will hit Earth: again. We still can't prevent that, not yet. More at A Catholic Citizen in America .

Authority, Superstition, Progress

Image
(From Diliff, via Wikimedia Commons, used w/o permission.) Authority, superstition, and misapplied technophilia (it's a real word ) rate at least one post each: but that'll wait until another day. Days. This time I'll take a quick look at all three, and then say why I don't believe in Progress with a capital P — and don't yearn for the 'good old days.' More at A Catholic Citizen in America .

Right-Handedness and Evolving Jaws

Image
At least one Homo habilis was right-handed, about 1,800,000 years ago. It's the earliest evidence of handedness in humanity's history. So far. Our jaws may have started out as armor plate, not gill arches. Paleontologists found a second Silurian placoderm species with surprisingly familiar jaws.... ...Before talking about Homo habilis, and new evidence showing how jaws evolved, I'll do my usual explanation for why science doesn't upset me....

Alchemy, Science, Life, and Health

Image
(From BBC, via Wikipedia, used w/o permission.) ("I find that nothing's ever exactly like you expect...." ( Professor Richard Lazarus )) A mad scientist's lot is not a happy one. All he wants is to redefine being human: and the next thing you know, he's eating guests at his victory celebration. Doctor Who's The Lazarus Experiment doesn't have much to do with The Devil Bat and The Brain That Wouldn't Die , apart from featuring a mad scientist — and science gone horribly wrong. Some movies, like Fantastic Voyage and Things to Come , present science and technology as useful. But "tampering with thing man was not supposed to know," as Mr. Squibbs put it, keeps the plot going for quite a few; like Altered Species , They Saved Hitler's Brain , and Island of Lost Souls . Reticence, reasonable and otherwise, regarding new ideas isn't new.... More at A Catholic Citizen in America .

Elastic Brains and New Tech

Image
Maybe 'you can't teach an old dog new tricks,' but apparently the adult brain isn't nearly as rigid as scientists thought. I'll be looking at neuroplasticity, the idea that brains can change; research that may lead to better neural interfaces; and 'brain training' games.... ...We've been learning a great deal about the human brain and how it works. That's a good thing for me, since I have maintenance issues with mine.... More at A Catholic Citizen in America .

Bioethics and a Three-Parent Baby

Image
A Jordanian couple have a baby boy: who does not have a lethal genetic disorder, thanks to DNA transplanted from a third person. Four of his siblings did not survive the procedure. I'll be talking about the decisions involved in that procedure, research involving "tiny brains" grown from human cells, genetically modified humans grown as research subjects, and water bears.... ...After discussing recent genetics news, I'll share why I take human experimentation and medical ethics personally, and what I see coming in the near future....

Europa, Mars, and Someday the Stars

Image
Scientists think they've detected more plumes of water, shooting up from near Europa's south pole. It's early days, but we may have found a comparatively easy way to collect samples from the Jovian moon's subsurface ocean. Stephen Hawking says humanity needs to keep exploring space. I agree, although not quite for the reasons he gave. SpaceX tested an engine they plan to use on their Mars transport, and Gaia's data seems to have raised as many questions as it answers.

The Minden Monster, What Killed Lucy

Image
The 'Minden Monster,' a whacking great carnivore that lived about a hundred million years before T. Rex, is in the news again. Studying it will help scientists work out details of megalosaur development. I'm fascinated by that sort of thing. Your experience may vary. Other scientists think they know what killed Lucy, our name for a famous Australopithecus afarensis skeleton. It looks like Australopithecus afarensis was a little more at home in trees than we are.
