DNA, Babies, Life, and Death

Image
DNA evidence in a court case isn't new: but deer DNA in a poaching trial is. Less than two decades after a cloned sheep 's birth, British Members of Parliament okayed human cloning: using DNA from three people. Scientists who think this is a good idea may be right: at least for some versions of the new tech. More at A Catholic Citizen in America .

Mutant Malaria, Designer Babies and Ethics

Image
Malaria that's resistant to a very successful anti-malaria drug is spreading. The good news is that scientists know where this particular strain's immunity came from. Other scientists say that "society needs to be prepared" for designer babies, and that "it is time for a serious public debate on the issue." More at A Catholic Citizen in America .

Birthright

Image
This story was posted in 2010, in another blog: " Birthright " Drifting at the Edge of Time and Space (February 19, 2010) Despite the stories you've seen, there never were very many Voini. Like any alter, each Voin was expensive to grow. Also, unlike the Gung Yan, Voini had earned an unpleasant reputation during the recent wars. Between limited production, judgments after the Suspension and 'Voin hunts,' there are now perhaps only a few dozen surviving Voini. Perhaps it is best this way....

DNA Test Hype; and Studying Life's Origins

Image
A company whose DNA test was banned by the FDA is back: in the United Kingdom. Meanwhile, scientists are learning that complex organic compounds may be forming in Titan's atmosphere: another piece to the puzzle of how life began. Another team found that up to half of Earth's water came from interstellar space. Finally, a quick look at astrobiology and assumptions about intelligent life in the universe.... ...We've known that traits are inherited for a thousand generations, maybe more, and applied that knowledge. The deal Jacob made with Laban in Genesis 30:17 - 3:13 at least hints that Jacob knew how to make sure many dark sheep and spotted or speckled goats were born....

Regeneration: Getting Closer to Growing Lost Organs

Image
Too many folks die, waiting for a compatible donor organ. We can't coax a patient's body into growing a new heart or kidney: yet. But we can build made-to-order bladders, and scientists have grown a new thymus: inside a mouse. It's a first step.... ...If starfish and some mice can regenerate complete missing parts: why can't we? Right now, we don't know. Not for sure. It probably has something to do with our immune system, and the way our bodies deal with injury.... More at A Catholic Citizen in America .

Neurosynaptic Cores and Retinal Implants: Getting a Grip About Tech

Image
IBM's neurosynaptic cores may not show up in home computers for years. Their circuits emulate a brain's neural circuits: and require an entirely new sort of software. Retinal implants are another matter. Thanks to new tech, several folks who would have been blind can see: a little.... ..."Metropolis," Tsukumogami, and the Roomba Revolution that Wasn't The inventor Rotwang in Fritz Lang's " Metropolis " is more 'evil wizard' than 'mad scientist:' my opinion. It's still a good movie: but not, I think, a particularly realistic look at what we'll see in 2026. Rotwang's maschinenmensch looked more like the human she was built to impersonate after a high-tech makeover, but even without upholstery she was remarkably — human.... But so far, artificial intelligence has been quite obviously "artificial:" and emphatically not up to the task of leading a Roomba revolution. More at A Catholic Citizen in America

Mutant Mosquitoes and a Made-to-Order Cancer Treatment

Image
After an utterly unscientific survey, I found that lists of dangerous animals include critters like sidewinders, piranha, and tarangual hawks . The latter are smaller than hawks but big for insects: and that's another topic. A few list-makers are savvy enough to include mosquitoes. These blood-sucking pests aren't dangerous by themselves: it's the lethal diseases they carry. The good news is that scientists are learning how to kill mosquitoes without poisoning people.... ...Health and Using the Brains God Gave Us... ..."Is being healthy okay?" Maybe that sounds like a daft question, or maybe not. Reading some of the more maudlin 19th-century 'lives of the saints,' a person could get the impression that sainthood required either a messy martyrdom, or dying of some horrible disease: smiling all the way. There's more to sainthood than that, and that's yet another topic. ( February 14, 2010 ) I occasionally run into news about someone who

The Oldest Known Heart; Tweaking Bacteria; and Looking for Life in the Universe

Image
A 520,000,000 year old fossilized heart caught my eye this week: so did genetically engineered bacteria, and the continuing search for life in the universe.... ...I don't need an iPad to be Catholic: which is just as well, since I don't own one. My son has smartphone, and that's another topic. Catholics coped quite well without WiFi gadgets in their pockets: and without pockets, for that matter. But our faith doesn't depend on avoiding new ideas and technology. We've even been at the cutting edge of new tech a few times: like Gothic cathedrals , stone buildings with walls made mostly of stained glass. The pointed arches, ribbed vaults, and flying buttresses of Gothic architecture are traditional now, but 12th century traditionalists were horrified at the 'barbarous' style.
