DNA and Cancer

Image
Apparently quiet a few sorts of cancer 'just happen,' no matter how much fiber we eat, how much we don't smoke, and how far we run each day. Or exercise, in my case. Thanks in part to now-replaced defective hips, my running days never really happened. That doesn't mean that we're all gonna die from random cancer. I think it means we should think about paying more attention to testing before symptoms appear.... After talking about oddly-under-reported 'cancer' news, I kept going; mostly about mutations, and why being healthy is okay... More at A Catholic Citizen in America .

Face Transplant at Mayo

Image
Andy Sandness wasn't born looking like that. He's lived with the consequences of a "wrong choice" for more than a decade. Agreeing to get Mayo Clinic's first face transplant won't undo his decision. But now he has a second chance for a normal life. More at A Catholic Citizen in America .

Brain Implants and Rewired Monkeys

Image
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....

Different Sorts of "Dead"

Image
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 .

Sweet Potatoes, Genes, and Long Life

Image
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 .

Elastic Brains and New Tech

Image
Maybe 'you can't teach an old dog new tricks,' but apparently the adult brain isn't nearly as rigid as scientists thought. I'll be looking at neuroplasticity, the idea that brains can change; research that may lead to better neural interfaces; and 'brain training' games.... ...We've been learning a great deal about the human brain and how it works. That's a good thing for me, since I have maintenance issues with mine.... More at A Catholic Citizen in America .

Bioethics and a Three-Parent Baby

Image
A Jordanian couple have a baby boy: who does not have a lethal genetic disorder, thanks to DNA transplanted from a third person. Four of his siblings did not survive the procedure. I'll be talking about the decisions involved in that procedure, research involving "tiny brains" grown from human cells, genetically modified humans grown as research subjects, and water bears.... ...After discussing recent genetics news, I'll share why I take human experimentation and medical ethics personally, and what I see coming in the near future....

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 .

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.

Kidneys, Experiments, and Ethics

Image
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 .

Mutant Cows, Mass Migrations, and a Brain Gene

Image
Bovine tuberculosis may not be a big problem, if Ministry of Agriculture in Northwest A&F University, Yangling, research pays off. Meanwhile, we may be learning who made Europe look and sound the way it does today: and scientists at the Max Plank Institute discovered how a uniquely-human gene helps our brains grow.... I've seen attitudes toward science and technology shift, quite a bit. I grew up when quite a few folks still thought human ingenuity would solve all our problems: or at least make "the future" a magical place to live.... More at A Catholic Citizen in America .

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 .

"Months of Misery" and Job's Friends

Image
My wife and a friend are making bread, about 15 feet from my desk. They're having a great time, and I'm trying to not get distracted while writing this post. The results may be interesting. Or confusing. I'll let you decide which. Thanks to some very powerful prescriptions, my ADD-inattentive and major depression isn't nearly as hard to handle as it was: which reminds me of this morning's first reading.

Robin Williams, Suicide, and Hope

Image
Robin Williams was a few months older than I am when he died. That photo is from 1979, when he was becoming famous for his role in " Mork & Mindy ." I admire Williams' work, regret his addiction to cocaine and alcohol, and am sorry that he is dead. He was a remarkably talented actor and comedian. Sadly, he apparently decided to hang himself. We can't be sure, but it's likely that suffering from depression had something to do with his death. Celebrity deaths get heavy media coverage: so when yet another movie star dies from suicide, drug overdose, or some other avoidable cause, it can seem that fame leads to self-destruction. Although famous folks from Hannibal to Margaux Hemmingway killed themselves, I think it's prudent to remember that many high-profile folks didn't: like Lauren Bacall and Bob Hope . I'll be writing mostly about life, depression, death, and why I haven't killed myself. You'll find links to articles about Rob
