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.

Space Aliens and Life's Ladder

Image
I'd be surprised if many folks took movies like " Earth vs. the Flying Saucers ," " Invaders from Mars ," and " Plan 9 from Outer Space ," seriously: as something other than entertainment, anyway. All of which has about as much to do with space exploration, astronomy, and SETI, as Keeping Up with the Kardashians does with family counseling . I'll be talking about SETI, the search for extraterrestrial intelligence; the Fermi paradox; and whatever else comes to mind — but first, the Copernican principle , which arguably sounds cooler than the mediocrity principle .

ESA's Gaia, HD 164695, and SETI

Image
Scientists working with ESA's Gaia space observatory published the first part of a three-dimensional sky map this week. It'll be the most comprehensive all-sky survey done so far. Not unexpectedly, this year's 'ET calling' headlines gave way to something slightly more down-to-Earth. We may eventually pick up an artificial signal from the stars: but that burst of radio noise from the direction of HD 164695 was almost certainly due to a clerical error of sorts. It wasn't our first false alarm, and I doubt it will be the last. More at A Catholic Citizen in America .

Philae, Jupiter, and Life

Image
Scientists spotted Philae, the European Space Agency's spacecraft that crash-landed on 67P/Churyumov-Gerasimenko in 2014: which will help them make sense of data sent back while the probe still functioned. Other scientists think they’ve worked out where carbon near Earth's surface came from, and the Juno orbiter has been sending pictures of the giant planet. More at A Catholic Citizen in America .

Proxima Centauri b, Looking for Life

Image
Looking for extraterrestrial life is still a science in search of a subject, but it’s getting increasingly difficult to argue that there couldn’t be critters out there. Today I’ll be talking about the search for life in the universe, a possibly-habitable planet circling the next star over, and a planet that couldn’t possibly be habitable. Make that not habitable by life as we know it. Life using fluorine and carbon as we do hydrogen and carbon, with sulfur as a water-substitute — is a topic for another post....

Faith, the Universe, and Wisdom

Image
I think the universe is billions, not thousands, of years old; Earth isn't flat; Adam and Eve aren't German; poetry isn't science; and thinking is not a sin. If you've been reading my posts, you know why being a Christian doesn't interfere with my interest in science. Feel free to skip the rest of this post. It's mostly about reading the Bible, the universe, and getting a grip. I'll be back next Friday, 1 most likely talking about Proxima Centauri b , a planet orbiting the next star over from ours: in Proxima's habitable zone. More at A Catholic Citizen in America .

Brogdar, Öetzi, and Piltdown Man

Image
Archeologists found a big stone structure buried under a 43-century-old garbage dump in the Orkney Islands. Öetzi, Europe’s frozen mummy, got his wardrobe from many different critters: why, we don’t know. Piltdown Man’s in the news again, too. Looks like Dawson was the only culprit.

Polio, Zika, and Using Our Brains

Image
Polio is back in Nigeria: only two cases that we know of; which isn’t particularly comforting, since most folks with polio have no symptoms. The good news is that vaccines are available: and may get to most of those who need them before the disease does. Zika, another viral disease, is still in the news, this time a case in Texas that affected a baby. On a happier note, researchers are making progress on a brain-machine interface that could help folks walk again. More at A Catholic Citizen in America .

Earth Overshoot Day and Pollinators

Image
Australia's Earth Overshoot Day happened earlier this week. It used to be called Ecological Debt Day, involves a lot of math, and assumes that Earth's glaciers, deserts, and oceans, are pretty much all the same thing. The basic idea, that we shouldn’t waste resources, isn't silly, and I'll get back to that. Some other scientists say that we should pay attention to pollinators. I think they're right.
