Using Vaccines Wisely

Image
Using drones to deliver vaccines seems reasonable for places like Vanuatu. But vaccines won't help if folks don't know how to use them correctly, or can't. Others avoid vaccines because they believe warnings from dubious sources. More at A Catholic Citizen in America .

Misusing Opioids

Image
"Crisis" or not, opioid overdose is a problem. A lethal one, sometimes. We've used one opioid, opium, for millennia. Others have been developed during my lifetime. They're all useful: and dangerous if misused. More at A Catholic Citizen in America .

Exoplanet Frontier

Image
We wouldn't expect to find life on 51 Eridani b, even if were the size of Earth and at the right distance from its star. The planet is only a bit over 20,000,000 years old. At that point in our home's long story, the earliest critters wouldn't appear for at least another several million years. We've discovered thousands of new worlds so far, some a bit like Earth, most not; and many not like anything in our Solar System. Scientists are starting to make sense of what's being found, and discovering that we have a very great deal left to learn. More at A Catholic Citizen in America .

Old Truths, New Aspects

Image
The biggest critters with backbones are living today: baleen whales. Finding the largest of them started getting harder about a century back. We didn't quite drive the blue and fin whales to extinction, happily. We're learning when they got so big, and maybe why. We're also learning more about origins of dinosaurs and the domestic cat. It's not the same origin. One happened around the time we started storing grain, the other 200,000,000 years ago. Give or take a bit. More at A Catholic Citizen in America .

New Worlds: The Search Continues

Image
There's a huge telescope under construction in Chile: the E-ELT. When compete, astronomers using it plan plan on looking for new worlds, and observing the early universe. We may have spotted a second super-Saturn. We'll know more about that in September.... ...Telescopes have come a long way since Galileo repurposed the " Dutch perspective glass " for astronomical observation. About Galileo, Copernicus, the sun, and the Church: it's true.... More at A Catholic Citizen in America .

Ammonites, Dinosaurs, and Us

Image
Today's world is remarkable for a lack of dinosaurs. Big ones, anyway. Those critters would have been among the first things someone would notice here for upwards of 200,000,000 years. Then, about 66,000,000 years back, something awful happened. The only dinosaurs left are those little tweeting, chirping, and cawing critters we call birds. Ammonites had been around for even longer, but whatever finished the 'thunder lizards' wiped them out, too. We showed up much more recently, and are learning that there's a very great deal of our past, and Earth's, that we don't know. Not yet.... More at A Catholic Citizen in America .

Good Intentions

Image
Variations on "dead men tell no tales" go back at least to 1560 or thereabouts in my language. The idea is much older. 1 As advice goes, it's arguably flawed. Folks who are dead aren't chatty, but their bodies occasionally pop up at inopportune times. I'll be talking about unmarked and unremembered graves, insane asylums, and similarly-uncheerful things. It's not all bad news, though. More at A Catholic Citizen in America .

First Americans?

Image
Scientists used new DNA screening tech to study caves in Belgium, Croatia, France, Russia, and Spain. What they found wasn't a big surprise. What's exciting about the news is that we now have another tool for unraveling our family history. We've been pretty sure that nobody lived in North America until about two dozen millennia back. That may change, if scientists who say they found 130,000-year-old tools in San Diego County, California. Quite a few other scientists are dubious, understandably. I took a longer look at what we've been learning about Homo naledi. They're folks who don't look like humanity's current model. We found their remains in a cave they probably used as a crypt. Since you may be reading my stuff for the first time, I'll review why I think truth is important. All truth, not just the bits I grew up knowing about. Also why I take the Bible seriously, but not 'creation science.'... More at A Catholic Citizen in America .

Repeatable Results That Aren’t

Image
I'll be talking about scientific research that may not be "fake:" but isn't reliable, either. The good news is that many scientists want to fix the problem. I'll also take a look at truth, beauty, Copernicus, and how a science editor sees faith and science. Faith and science Truth and Beauty "...There Will be Babblers...." Being Scientific News and views... More at A Catholic Citizen in America .

Looking for Life: Enceladus and Gliese 1132 b

Image
We haven't found life on — or in — Enceladus. But we've found organic compounds in the Saturnian moon's salt-water geysers. Scientists detected an atmosphere around Gliese 1132 b, a planet about 39 light-years away. It's Earth-like, in terms of size; but too hot for life as we know it. We'll almost certainly learn a great deal, though, by studying its atmosphere.... ...Abraham, Moses, and Minnesota I take the Bible, Sacred Scripture, very seriously. (Catechism of the Catholic Church, 101 - 133 ) I don't, however, insist on believing only what I find in the Bible. That's just as well, since I live near the center of North America. I'm pretty sure that Abraham, Moses, Joshua, Saint Peter, and the rest, didn't know that the land I live on exists. But I'm quite sure that the State of Minnesota is real: even if it's not "Biblical."... More at A Catholic Citizen in America .

Mars: Leaky Red Planet

Image
What we're learning about Mars, and a new type of really small spacecraft, reminded me of earth, air and kilts. Also pharaohs, Thomas Paine, and Lord Kelvin. By then I was running out of time to write something more tightly-organized. I figured you might be interested in some of what I have written. On on the other hand, maybe not. So I added links to my ramblings before and after what I said more-or-less about the science news, and figure you can decide what's interesting and what's not.

TRAPPIST-1: Water? Life??

Image
TRAPPIST-1's planets may support life: or not. We don't know. Not yet. We're pretty sure that all seven are rocky worlds, like the Solar System's inner planets. Three are in the star's habitable zone. The inner two definitely do not have one sort of atmosphere that would make life as we know it impossible. Even if we don't find life there, we'll learn a great deal while looking. More at A Catholic Citizen in America .

Pollution: Still Learning

Image
Scientists found PCBs and PBDEs in deep-sea critters, armyworms are on the march in Africa, and Mexico City's air isn't as clean as we'd hoped. Rational concern seems reasonable.... ...Last week I talked about blaming our tools for our mistakes. ( February 10, 2017 ) This week I'll revisit Lovecraft's "placid island of ignorance,"sort of....

Bogs and Bison

Image
The good news is that bison are back in Banff, and Britain's bogs may bounce back, too. Keeping wetlands wet isn't what many folks had in mind, back in my youth. But as I keep saying, we've learned quite a bit since then.... ...This post's afterword is a quick look at how folks have perceived natural resources, plus a bit about pessimism and being human....

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 .

Climate Change Continues

Image
Climate change is still in the news. So is a growing crack in an Antarctic ice sheet, and a Ladybird Book co-authored by England's Prince Charles. The book, "Climate Change," is a Ladybird Expert Book: written with adults in mind.... ...This post has an afterword, mostly my take on climate change and being human....

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 .

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 .

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 .
