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....

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....

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 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....

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 .

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 .

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, 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 .

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....

Deciding who's dead and who's not isn't always easy. But getting the answer right can be a matter of life or death.... More at A Catholic Citizen in America .

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....

One woman decided to take a road trip after learning she had a terminal illness. Another switched careers. Both choices make sense, given the circumstances. This year's World Food Prize goes to a team who developed a new sweet potato, scientists found a virus with spider genes, and there's a lively difference of opinion regarding human life span. We've learned a lot since my youth, and there's a great deal left to learn. More at A Catholic Citizen in America .

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.

English Bulldogs aren’t what they used to be: which is a problem for folks who want the breed to survive. A team of scientists says that the British mascot’s bloodline is more than a bit too pure. Other scientists developed MouSensor, mutant mice with open slots for plug and play genetic code. Finally, a tiny robot with rat muscles that swims like a fish. More at A Catholic Citizen in America .
