You're missing a key fact, which others have noted, but I would phrase it differently. Calcium is the end-stage of atherosclerosis. In other words, only advanced atherosclerosis has calcium. The electron beam CT test can, therefore,

Staggering to think that you can look at your hand and see evidence of relativity in action.

Perhaps a more enlightening view is in the book "The Socratic Method," by Ward Farnsworth, who is dean of the UTexas Law School. This is a great book for those just starting on the adulthood road, though it could have been shorter

We had an Altair at home, that my father assembled from a kit. That version did not have a serial port. It had only the switches on the front panel. I did succeed in inputting some programs and in having them run. But of course it was ap

There is risk in this approach. Nobody has any real idea what supplements are doing in all of the bodily tissues, and sometimes the effects are not benign. "Folate acceleration" of cancer is just one such cautionary tale. Vitami

First computer I ever programmed: 1970, in 7th grade math class, after school. It was a big deal -- actually having access to a computer! It wasn't a "personal computer" for us, because our school had just the one machine, a

Correlation may not equal causation, but correlation does define syndromes. In medicine, a "syndrome" is any collection of findings that tend to occur together. A syndromic label says nothing about how or why the findings occur

That is exactly the thesis of a recent book [0], summarized, more or less, as: "When there is no objective method to rate performance, then the social network becomes the measure of performance." [0] https://www.amazon.

> I've seen transdermal plastic beads put in some interesting places - but they're hardly transhumanist. Transdermal metal beads, in the form of little bells, were put in "interesting places" in India in the 1500s.

I tried to get it to play doctor... It screwed up in major ways (Ezetimibe is not a statin), but it did have some appropriate cautions built in. Still, not ready for prime time. In the end, it sounded like it was pushing Ezetimibe! :-) [

My money is that they will have to disclose inputs, if for no other reason than to address the uncertainty about race as a possible input.

A high price-point could eliminate random teenagers for some number of years, but it will not eliminate teenagers in well-to-do families -- especially if gene science experiments can get the teens into prestigious schools. A treaty would be

Yes, misanthropes are a hazard, but I worry also about a scientifically sophisticated teenager who gets jilted or suffers some other emotional shock, and then decides to end it all for everyone. A species is in trouble when its entire futu

And ICD is not a pacemaker. An ICD costs about $30K. When its battery wears out, the battery is replaced, not the ICD. So there will be no replacements of already-implanted ICDs because of this problem. Also, it is a big deal to redesign

Blaming Apple is not absurd. The interaction between magnets near the chest and cardiac rhythm devices has been well known since at least the 1980s. Even I can remember a published case report of a person carrying a stereo speaker, and a ma

The Brits of that era were equal-opportunity smallpox infectors. They captured some of George Washington's slaves, infected them with smallpox, and then released them on the battlefield at Yorktown, hoping to spread disease back to GW

The Lancet had a series of articles in the early 1980s about smallpox in Egyptian mummies, and the risk to Egyptologists. As far as I remember, at least some mummy bodies were preserved in cool, non-dry surroundings which are the best cond

Not hastily: the National Guard goes back to 1636 and is the oldest military force in the United States.

The F-15 wing in Fresno has an air defense mission. They are on 24/7 alert in case US airspace is threatened. The fact that they are assigned to the National Guard instead of the active duty Air Force is a money-saving move: Guard wi

Any theory for the firings has to explain why the enlisted chief was fired. He would not have been involved in any orders related to the F-15. His responsibility is the enlisted force, not airplanes or their use. So I don't buy the

Looks to me like a bot generated the article, given its weird capitalization and inconsitent internal references. Here is the press release from Columbia University: http://newsroom.cumc.columbia.edu/blog/2017/11&

You have inverted the temporal arrow. The question is not what's behind, but how much was left yet to do. Deeds left undone -- that is the tragedy.

It's a Johnny-come-lately. Every day going to work I used to drive by the "Shot Tower" in downtown Baltimore, USA (it's still there, I'm not), built in 1828 to make various types of spherical ammunition, including

Baltimore would be a great choice. Easy to draw talent from DC area -- housing prices much lower. Plenty of land both right in town (sad, actually) and in the suburbs. Would be a very big fish in town, and could do much to revitalize an

There is an acquisition bias inherent in this article. Reading 40 hours a week should not be viewed as an unadulterated good that is beneficial in all cases. I've known people who have escaped into reading with that kind of time commi

Am surprised the article did not mention two genes that are known to link catecholamines (adrenaline et al) and ventricular tachycardia. One gene is for the cardiac ryanodine receptor, and the other is for the CAS2Q gene. An obvious conclu
