While interesting, I'd wish they'd worry at least as much about the flavor as the nutrition.

If this holds up, this will be another well-deserved blow to those who insisted we should have gone full speed ahead with embryonic stem cell research and never mind those who had ethical qualms about the practice.  More and more it's looking like we don't need to tear apart human embryos to get stem cells.

Interesting: Sugar is even worse than thought (link to the original study contained therein), or just as bad depending upon your circle. The nice thing about cleaning up your diet is that once something is gone, it's gone. For example, if you really do eliminate excess sugar your tolerance to it goes down so that something that used to not be very sweet now is too sweet. While salt is an issue, sugar is a big one.

I can believe that. I like lemonade, but not the premixed varieties as they invariably are too sweet.  Similarly, I hate cake that has more than a thin layer of frosting just barely thick enough to not see the cake thru.

That theory has been around awhile, but there are quite a few skeptics.

Do you think this latest study helps validate that hypothesis? 

No, because it doesn't address the concerns that skeptics have with it.

The DoD already does its needed space activities outside of NASA and its budget and other than perhaps some joint research into improved launch systems, no real synergies to be gained from mixing the two at this point.

If confirmed, it probably would get the name of a Roman god or goddess that hasn't already been used for a minor planet.  How about Libertas? Wink

Bad science, at least in this case. The genetic condition that makes him desirous of a new body also makes him a poor transplant prospect. His brain cells and renaming central nervous system wil continue to deteriorate. It's like deciding to repair an old rust bucket of a jalopy by transplanting the old engine into a new car. There's almost no chance this'll extend his lifespan tho it may temporarily improve his quality of life. But the organs of his future donor could help many people if marvelled out individually.

Why should the distribution of matter and antimatter be homogeneous? It would seem to make perfect sense that while our local supercluster is predominately matter, other superclusters are predominately antimatter.

Whether Plimpton 332 was intended for calculations that today would be considered to be more part of what we call algebra or trigonometry has been in dispute for decades. So other than defying the current consensus that it's more algebraic than geometric, this person's contribution to the morass of publish or perish appears inconsequential. Besides, the fundamental distinction between trigonometry and geometry is that the former explicitly links angles and sides, which this person isn't claiming. Dr. Mansfield is only claiming it was used to solve problems we'd use trigonometry to solve, not that the Babylonians developed trig centuries before the Greeks.

well that's weird...how had I missed that were different kinds (phases?) of ice?
To begin with, all ice on the surface is in the phase Ice-Ih.

Ice-VII requires pressures over 20,000 atm to exist.

To be fair, you might have heard about it, but thought it was science fiction.

The impact isn't the new theory, but that having such an impact increased the odds of life developing here.

It's hard to get sad about an inanimate object, but Randall Munroe managed to do that for me today over at xkcd.



And in case you don't know why. here's why.

Where is this idiot getting his figures?  50% greater survival rate ?!?!? Any successful human colony on Mars is going to be in a sealed environment with little chance for natural section to be a factor. The only significant environmental difference will be the 0.38g gravity field.

Eventually we'll most likely terraform the planet so we don't have to live in a sealed environment.

Possibly, but certainly not anytime soon. Without even trying to get any particular atmosphere there, we'd have to increase the atmospheric pressure more than 10 times what it currently is just to reach the Armstrong limit (where water boils at normal body temperature) which is an absolute minimum for human survival. We don't have the technology to do that at present, and even if we did, it won't make economic sense until there is a well-established human presence on Mars.

There's also the anthropocentric viewpoint that an intelligent civilization would necessarily emit extra EM radiation.

Apparently you've never heard of either Niven's law of time travel or of the Temporal Prime Directive, since you naively believe that our lack of knowledge of people travelling back in time is proof it cannot be done.

Oddly enuff, astronomers already knew back then about carbon stars, of which the sun is not one.

Fortunately, most of Zealandia is already claimed as part of various EEZs, so whether it really is a continent or a microcontinent won't affect seabed rights that might cause a dispute between New Zealand, Australia, or New Caledonia.

Hasn't string theory been largely discredited....since like 2002?

No, but it hasn't advanced beyond being merely a hypothesis rather than a widely accepted truth.
