Climate change talks in Paris started this week, with the usual protesters and editorials. Meanwhile, folks in Minnesota are shopping at Christmas tree farms: and a performance artist in Beijing made a brick from smog.... ...I'm convinced that climate change happens: and has been happening since before life began on Earth, 3,800,000,000 or so years back. As I've said before, the natural world got along fine without us. Now that we're here, however, we're responsible for its maintenance.... More at A Catholic Citizen in America .

First, the good news: releasing genetically-modified medflies and mosquitoes may mean fewer crop failures; and fewer deaths from malaria. Now, the not-so-good news: I'm pretty sure some folks won't think it's good news.... More at A Catholic Citizen in America .

I stopped using the term " Caucasian " several years ago. I've discussed the "Anglo-Teutonic" race, Neanderthals, and getting a grip, before. ( September 25, 2015 ; October 31, 2014 ) Turns out, folks from the Caucasus moved into Europe at least once — along with many other folks.... We're still learning about humanity's family history. It's a lot more complicated than we thought.... More at A Catholic Citizen in America .

Before the New Horizons mission, we knew Pluto was very cold, had little or no atmosphere, and that was about it. ( October 30, 2015 ; July 10, 2015 ) Now scientists think they've spotted 'ice volcanoes' on Pluto that look a lot like shield volcanoes on Earth and Mars.... ...we're rational creatures, created in the image of God, and "little less than a god." Studying this universe, and using that knowledge is part of our job. So is using our power responsibly.... More at A Catholic Citizen in America .

Scientists may have observed chimpanzees in different groups using a different sound when they mean "apple." Then again, maybe not. Either way, we're learning more about chimpanzees. Pliobates cataloniae, an ape that lived where Catalonia is now, had a gibbon-like skull: but apparently is more closely related to today's gorillas, chimps, orangutans — and us.

Images sent back from New Horizons gave scientists their first opportunity to see how big Kerberos is. It's much smaller than they expected, which raises new questions. Meanwhile, the Mars Reconnaissance Orbiter's instruments provided evidence that there's running water on Mars: every summer, on some crater slopes. It's not the Mars of Burroughs' Barsoom tales: but I think the planet is getting more interesting, the more we learn about it. More at A Catholic Citizen in America .

(From Alex Alishevskikh, cyberborean.org; via Flikr and Space.com, used w/o permission.) (" Trail of the object that exploded over Chelyabinsk, Russia, in 2013. " (Space.com)) Asteroid 2015 TB 145 won't hit Earth, but it will be only slightly farther from us than the Moon at 1:05 p.m. EDT, 5:05 p.m. UTC, October 31. I've talked about asteroids, Earth Time, and why thinking ahead makes sense, before.... ...Fifty years ago, we probably wouldn't have noticed an incoming asteroid until very shortly before it hit. Even if we did, there wouldn't have been much we could do, apart from praying — and that's another topic.... More at More at A Catholic Citizen in America .

Bits of carbon encased in zircon crystals more than four billion years ago may have come from living creatures. Then again, maybe not. Either way, we're learning more about Earth's long story.... ...This space-time continuum doesn't work like Anaximander 's model, either. Anaximander's cosmology had Earth in the center: but he speculated that we might not be standing on the only world, and that worlds change. Aristotle's cosmology had Earth in the center of the universe, too: but he didn't think multiple worlds existed. About 16 centuries later, educated Europeans like Dante Alighieri had a very high opinion of Aristotle.... More at A Catholic Citizen in America .

We're years away from safe pig-to-human organ transplants: but scientists using CRISPR gene editing tech are working toward that goal. Other scientists are discovering a chapter of humanity's family history: Eurasian immigrants returning to Africa, when the Shang dynasty and Egyptian Empire collapsed.

Kidney failure isn't always fatal these days. Hemodialysis or peritoneal dialysis can keep someone alive until a transplant donor shows up. Kidney problems kill about a million folks each year. It's not the leading cause of death for my 7,250,000,000-plus neighbors, but that's still a lot of deaths. Scientists in Japan grew working kidneys in rats and pigs. We're years away from grow-your-own kidneys for patients: but I think that's coming. Meanwhile, a scientist in England wants permission to collect people for genetic experiments. The Francis Crick Institute, Human Fertilization and Embryology Authority, and BBC News describe the proposal more discretely. More at A Catholic Citizen in America .

Scientists from University of the Witwatersrand found skeletal remains in South Africa's Rising Star Cave . This is a big deal, since it's the largest collection of hominin bones found in a single spot: and these folks may have been burying their dead 2,500,000 years ago.

Neanderthals apparently had bigger eyes than folks living today. One scientist says that means they didn't play well with others. Bonobos , chimps living south of the Congo River, squeak. The squeaks are the same, whether they're happy, sad, or angry — and may tell us something about how language developed.... ...I think accepting God's universe 'as is' makes sense, so I'll ramble on about hubris, movies, and St. Thomas Aquinas, before discussing Neanderthals and squeaking bonobos ....

New Horizons will pass by another Kuiper Belt object in January, 2019, if NASA's proposal gets the go-ahead. Closer to home, Dawn is still sending back data from Ceres: including an image of a very odd-looking mountain.... More at A Catholic Citizen in America .

Scientists created "super-intelligent mice" — but this isn't a cartoon, so the mice aren't hatching plans for world domination. The research may lead, eventually, to treatments for Posttraumatic stress disorder , schizophrenia , and Alzheimer's disease . Other scientists found hand bones shaped pretty much like ours: from at least 1,840,000 years back.... More at A Catholic Citizen in America .

Scientists are looking, literally, at a newly-discovered exoplanet, 51 Eridani b. It's less than 100 light-years away, about as far from its star as the gas giants in the Solar System: and very young, only around 20,000,000 years old. Studying 51 Eridani b should help scientists understand how our Solar System formed. HD 219134b is much closer: a little over 21 light-years away, in the constellation Cassiopeia. It's a rocky world, like Earth; but larger, and blistering hot. It's also the closest transiting exoplanet we've found so far. This is a big deal, at least for scientists who study planets.... ...Whether you know why I'm not offended by God's design choices or not, feel free to skip ahead to "An Infant Version of Jupiter" ; check out xkcd.com , and/or mainstream comics at gocomics.com ; or do something completely different....

We knew this universe was fading, but now scientists have a much clearer picture of how fast the lights are going out.... ...Other scientists are pretty sure they're detecting neutrinos generated inside Earth. "Pretty sure" isn't "really sure," though, so they're still working on that research.... ...Right after a very quick glance at natural philosophy becoming science, I'm going to say why I do not believe that thinking is a sin — again. You've probably read that sort of thing on this blog before, so skip ahead to Portrait of a Fading Universe , teach yourself origami, read a good book, whatever....

Scientists found evidence that Earth's magnetic field is more than a half-billion years older than we'd thought. As usual, that raises more questions. The European Space Agency's Philae lander detected a "rich array" of organic compounds on Comet Churyumov-Gerasimenko 67P, including hydrogen cyanide (HCN). This is a big deal, since much of Earth's water came from comets: and HCN may have helped life begin on our world. More at A Catholic Citizen in America .

During the 1950s, space aliens in the movies came in two basic models. Some were invaders — " Plan 9 from Outer Space ," " Earth vs. the Flying Saucers ," and " Invaders from Mars . The title character in " The Thing from Another World " acted like an invader. But I think the Thing's bad attitude might have come from being shot after the humans blew up his ship, and that's another topic. Then there's Klaatu, in " The Day the Earth Stood Still ," who stopped just short of walking on water. Between Klaatu, movies like " Prometheus , and folks who believe space aliens are angels , I'm not surprised that some Christians don't like the idea that we may have neighbors on other planets. As I keep saying, I don't believe that life exists elsewhere in this universe: or that it does not. We don't know, not yet. If we meet folks whose ancestors developed on another planet, I think Brother Guy Consolmago is r

Pluto may have nitrogen glaciers, and the planet's air pressure is much lower than scientists expected. Kepler 452b, "Earth 2.0," isn't the first roughly Earth-size planet found in a star's habitable zone: but the star, Kepler 452, is remarkably similar to our sun. Another planet, HIP 11915b, is the first we've found that's around Jupiter's size: and orbiting its star at about the same distance as Jupiter. This is the first other planetary system that 'looks like' our Solar system. Scientists still haven't found life elsewhere in the universe: but the odds seem to be getting better that we will, eventually.... ...A 'science threatens faith' op-ed got my attention this week, so I wrote about beliefs, reasonable and otherwise, before getting around to the interesting stuff. Feel free to skip ahead to Pluto's Probable Glaciers , take a walk, or whatever suits your fancy.... More at A Catholic Citizen in America .

(From NASA, ESA, and the Hubble Heritage Team (STScI/AURA); ESA/Hubble Collaboration; used w/o permission.) " The heavens declare the glory of God; the sky proclaims its builder's craft. " ( Psalms 19:2 ) Genesis 1:1 - 31 says that God created the universe, and us, and found everything "very good." Psalms 19:2 says that the celestial light show declares the glory of God.
