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.

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?

I'm an orthopaedic surgeon, and I doubt it's anything more than just a typical spacer that is commonly used.

OK found the article, and I'm corect.

The title is misleading - it's just a 3D printed version of spacers that are commonly used - it really doesn't look, nor function any differently than the ones currently being used. The patient had a non-ossifying fibroma - rare in the spine, but benign, and will turn into regular bone eventually. This could have been treated with some bone graft and a plate and screws, which is basically what they did.

Nothing really new here.

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".

I live in a rural area, and do dual-sport motorcycle riding on mountain trails in the Appalachians. There is a small "town" where we stop to fuel up and eat, and this place doesn't even have cell phone service. However, I did find that there is an Xfinity hotspot. Actually, I didn't even know what the Xfinity thing was until seeing this story, but it now makes sense why there was a "commercial" hotspot at this little crossroads. They allow two one-hour free trial sessions a month, which just happens to be about the frequency I ride through there, so it has been extremely useful to communicate while having lunch. So I give Xfinity a thumbs-up as it was that or nothing at all (and I do mean nothing) in this one particular place.

What Comcast needs to do is share just a tiny bit of this revenue with customers whose routers provide this service. It might only amount to a dollar or two a month, but that would be an incentive to have it turned on, and would offset the extra cost of electricity.

Money will say more in one moment than the most eloquent lover can in years.
