This makes sense. One of the things that drives me nuts about those cheap Chinese no-name Android tablets is the display. They draw every other pixel in a checkerboard type fashion, and if your eye is totally still then you don't notice. However if you move your eye quickly back and forth you can clearly see that only half the pixels are drawn at a time. So there's something about the motion that doesn't allow enough processing time to smooth that out. It's amazing how much our visual processing smooths things and even totally fills in parts that aren't even visible, but that requires an image to be steady at least to some degree.

It depends on how "selfish" the state is. State lawmakers are always looking to increase revenue and income into their state. Since automobile dealers are local, and they get a cut of auto sales, it is beneficial, generically, for states to only allow dealerships to sell cars and get their local, in-state cut of the revenue. So it takes lawmakers that can see beyond that immediate income and have vision enough to embrace the future even if it has some cost to their state.

Then of course you have states like Texas, that produce oil and gasoline, who don't like Tesla and their new-fangled 'lectric cars, who of course want to make it hard on Tesla because that is a threat to revenue for their state.

If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

Describing a concept, and making a fake CGI video of how it might work, does not mean they have "created it". They haven't even revealed where this is at in the development cycle, and the video is very clearly pure CGI. (for one thing, nothing on these augmented displays will look right except from the driver's perspective, which will be annoying for passengers, and the camera does not show the driver's perspective in this video).

With the "B column" (the column between the front and back door), why should I have to turn my head >90 degrees to see an oddly shaped screen that shows me what is only right behind the column? When I signal how about show me EVERYTHING to that side of the vehicle on a screen that's, um, like right in front of me so I don't have to take me eyes off the road or crane my neck?

MPAA and member studios Universal, Sony, Fox, Paramount, Warner Bros., and Disney have had lengthy email discussions concerning how to block pirate sites at the ISP level, and how to take action at the state level to work around the failure of SOPA in 2012. Emails also indicate that they are working with Comcast (which owns Universal) on some form of inspection of traffic to find copyright infringements as they happen. More information at The Verge."

This study "explains" nothing.

Such a pattern would provide an evolutionary explanation for such culling. It “might be adaptive,” Lee says.

An "evolutionary explanation" isn't an explanation. WHY do more male fetuses die than female during stressful situations? What is the actual mechanism causing this to happen? The answer to that is an "explanation". Further, given the relatively long time frames involved in human reproduction, how would this trait have evolved to cover such a large percentage of the population when it is only needed during stressful situations?

Maybe males require more resources from the mother as a fetus, or maybe the difference in hormones is the tipping point that causes more male fetuses to die in these situations. But just because it appears to be beneficial in some way in the vast scheme of things does not mean that it exists because it is beneficial evolutionary or was selected in some way.

Saying "we found it is beneficial for less male fetuses to be born during stressful situations" does not mean "less males are born because it is beneficial during stressful situations".
