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.

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 .

Early Agriculture, New Tech

Image
'Genetics news' caught my eye this week. DNA from barley that's been sitting in a cave for six millennia is helping scientists learn about agriculture's origins. A fits-in-your-hand Biomolecule Sequencer is at the International Space Station. If it works, folks up there won't have to send samples down for analysis. Finally, the world's first farmers were an unexpectedly diverse lot.... ...Science? In a "religion" blog??... More at A Catholic Citizen in America .

Cryonics, Smallpox, and Pope Pius VII

Image
I remember when heart transplants were front-page international news, not local human interest stories: and when polio vaccinations were new. I really do not miss the 'good old days.' I remember them, and they weren't. I also remember when cryonics was 'science fiction stuff,' not a highly-experimental and controversial medical procedure. I probably won't live long enough to see whether it works. But if you're young enough: you might.... ...Since I'll be talking about life, death, and medical practices, I'd better start by saying that I'm a Christian: a Catholic. Like it says in the Apostles Creed , "I believe in ... the resurrection of the body, and the life everlasting." I'll be explaining why I don't see a conflict between that belief and trying to save lives.... More at A Catholic Citizen in America .

Starshot, SETI, and the Universe

Image
We may be within a generation of sending probes on flyby missions to other stars, high-energy jets from several distant galaxies all point in the same direction, and we're learning more about hot super-earths. That sort of thing fascinates me, your experience may vary. Meanwhile, SETI researchers will be checking out red dwarfs: which may be more promising places to look for neighbors than we thought.

BEAM Prototype Habitat, Bigelow's Plans

Image
The BEAM Bigelow Aerospace habitat module, will be launched toward the International Space Station (ISS) today: if all goes well. BEAM is packed in the Dragon spacecraft's pressurized section. This cargo run also carries supplies for the ISS crew, and for several dozen of the roughly 250 experiments planned for Expeditions 47 and 48. ( SpaceX press kit ) After getting attached to the ISS and inflated, BEAM will mostly just sit there for at least two years: empty except when someone in the ISS takes samples and swaps out radiation sensors. I think that's a good idea, since BEAM is testing technology for Bigelow Aerospace rental properties in low Earth orbit. More at A Catholic Citizen in America .

Reaching for the Stars

Image
Scientists and engineers in BAE Systems' Project Greenglow are trying to control, or sidestep, gravity. Back on my side of the Atlantic, scientists at NASA's Eagleworks say they've successfully tested prototype RF resonant cavity thrusters and a warp field generator. Other scientists are skeptical. Very skeptical.... More at A Catholic Citizen in America .

Click To Pray: the Prayer App for REAL LIFE!

Image
Feel like praying? We have an app for that! At long last, the Pope's Worldwide Prayer Network has a totally unique app that connects people around the world to the Pope's prayer intentions--and to one another. Read all about it at Praying with Grace !

Luxembourg and Asteroid Mining

Image
Stories like " Rip Foster Rides the Gray Planet " and " Red Dwarf 's" Dave Lister singing "...Lived an old plutonium miner / And his daughter Clementine..." probably didn't help make asteroid mining seem like a serious idea. Then there's the 1966 Outer Space Treaty treaty: a tribute to the high ideals, and international politics, of the '60s. The idea was that anything we find outside Earth's atmosphere would belong to everyone. Nifty idea, not entirely wrong, and I'll get back to that. More at A Catholic Citizen in America .

Barsoom Development Ltd.

Image
The Curiosity Mars Rover sent a 'postcard' from Mars, a 360-degree view of dunes and a mountain in Gale Crater.... ...As usual, I'll ramble on about science, technology, and being human before getting to the interesting stuff: assuming that you think a robotic selfie from Mars is interesting. Not-entirely-as-usual, I wasn't finished rambling when I started the 'postcard' stuff, so this post has an afterword. I've done that before.... More at A Catholic Citizen in America .

SpaceX, Mars, and Someday the Stars

Image
First of all: Merry Christmas! I'll have something more seasonally-appropriate ready by Sunday. That's the plan, at least. Today I'll be talking about spaceships, practical and otherwise: and why NASA cancelled InSight's March 2016 launch.... ...Instead of trying to analyze the reasons, I'll just get started with the December 1938 issue of Amazing Stories, Columbus, Robert Goddard, the Hanseatic League, and why airlines don't use disposable airplanes — not necessarily in that order....

Mutant Medflies, GMO Mosquitoes

Image
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 .

The Halloween Asteroid: 2015 TB145

Image
(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 .

Pig Organs, Ancient Immigrants

Image
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.

Thomas Aquinas and the DARPA Robot Competition

Image
Korea's Team Kaist's DRC-Hubo humanoid robot walked through DARPA's 2015 robot competition: one of three to complete every task on the course without falling over. Meanwhile, Toshiba's (somewhat) lifelike ChihiraAico robot demonstrated 'her' voice in a Las Vegas trade show. More at A Catholic Citizen in America .

Dogs, Stone Tools, and Newly-Discovered Ancestors

Image
Australopithecus deyiremeda, a newly-discovered member of humanity's family, was in this week's news. We're also learning more about when some wolves started becoming dogs, and have discovered really old stone tools.... ...Humanity's family history is nowhere near as simple as folks figured when Carl Linnaeus published " Systema Naturae " in 1735....

A Robotic Tentacle, and Disney’s Baymax

Image
Disney Studio's film version of Baymax is fiction. Robots designed to work with people are real: although they're nowhere near as smart as their fictional counterparts. More at A Catholic Citizen in America .

Climate Change, Science, and the Vatican

Image
The 'Vatican science academy' is in the news again: this time because they've said we should use our brains. The topic was climate change, which tends to stir up sound and fury more than rational discourse. Meanwhile, one scientist implied a link between our "carbon dioxide crisis" and a lot of dead critters, some 201,000,000 years back. More to the point, I think, the team he was on has added a few more pieces to the puzzle of what caused the Triassic-Jurassic extinction event. More at A Catholic Citizen in America .

The Thumb-Brain Connection, and DIY Robots

Image
Scientists learned how using our thumbs changes our brains by collecting data from 26 smartphone users, 11 users of "old-fashioned cellphones," and electroencephalography. Building your own robot is getting a whole lot easier, now that RoboCORE is around. It's a robotic central nervous system you can program with C++ or Python.... When I was in high school, I learned that adult brains were static, unchanging. Neuroscientists thought, or assumed, that once we get past youth — that our brains don't change: no new neurons, no new connections between neurons. They were wrong....

Dawn's Arrival at Ceres; Sims and "Chaos"

Image
Dawn became the first spacecraft to orbit two asteroids or planets other than Earth last week. More to the point, we're learning more about these survivors from the early Solar System. Meanwhile, from the world of infotainment , "chaos" and the early Solar System.... ...Either way, Vesta and Ceres are — most likely — the last remaining large protoplanets : which makes them valuable samples of the early Solar System. Apart from size and distance from our sun, they're very different: which also makes them intriguing places to study. Scientists have working ideas about how Vesta and Ceres ended up where they are, but those hypotheses may change when we learn more from the Dawn mission. There's quite a bit of data to work with already, from Dawn's stopover at Vesta.... More at A Catholic Citizen in America .
