The bringing in crime is more of an urban legend than simple nimbyism hence the 'probably' in my comment. But I didn't know construction costed it out of the running. Googling around shows a plan on the table and guess it would be a deeper station than Rosslyn?

Complete bullshit. If you can already pick up everyone's identity from the cumulative breaches, imagine what happens within a company. As it is, all of this data is even collectible without TikTok. It's just the icing on the cake: It's a training corpus for AI audio and video and other useful intelligence like measuring US sentiment towards China. The number of uses is endless. On the bright side, we're gonna get great English instructions included in the products we buy going forward.

Reply to Why do some animals have sex determination which is not genetically determined? by SuperRMo7
As I recall from school, all reproduction is asexual or sexual. But it gets complex because asexually reproducing bacterium are able to laterally transfer genetic material. And then there are viruses out there incorporating themselves into genomes. And so it appears to me that the very basis of reproduction has and-ifs and it just gets more sophisticated from there.
For example, environmental factors are able to affect genetic expression as you observe with reptiles.
However, if you take a planaria (flatworm) and mechanically split it in the proper manner, you can get two individuals.
And then we toss in hermaphrodism: plants don't stop and go ahead and fertilize themselves because their genetics provides for two sets of sexual organs. The angiosperms have been very successful at an evolutionary level as we are able to witness by so much green.
>Why do some animals have sex determination which is not genetically determined?
So your Q is about "environmental sex determination" and the mechanism is genetic. The organisms have the genetic ability to express all sexual phenotypes and the egg of a reptile makes a genetic decision to express a certain set of genes based on an environmental cue if hot or cold. It's just a game time decision.

Could be a good solution regarding social media.

Interesting take: if Twitter is required for emergency response, should it not be public infrastructure?
If not, good on Turkey for shutting down a communication channel that will just add more misery and suffering to the human experience during this awful catastrophe.
Seems to me it would be useful as public infrastructure.
So if it is, it sure seems like the company needs to be regulated to provide a quality of service.

Reply to comment by UnamedStreamNumber9 in Why is wind energy generation greater during the night? by ZeroTheHero524
Yep! A basic use case is pumped storage - hydro - pump water up hill for peaking at a later time.
srandrews t1_j66chmx wrote
Wind is a very location specific phenomenon. Sometimes days are windy, sometimes nights. Such conditions greatly influence the economics of a wind farm. For example, it is ideal to line up peak production with peak demand. And peak demand is typically during the day. And the other thing to keep in mind is that if there is no load to serve, a wind farm won't generate.

Reply to comment by LincolnsVengeance in Sending a signal faster than light is time travel? by KingOfTNT10
Your point on time and relativity is a good one. But that should not be called time travel. People colloquially use "time travel" to denote an event that breaks causality. You are probably thinking about nonlocality and entanglement. Those do not transfer information or material in a superluminal manner.
I appreciate your distinction between hypothesis and theory. For at least the sake of our current societal ills, a hypothesis should not be taken as a truth until it becomes a scientifically accepted theory.

Reply to How do we know oxygen, and not another element, is the third most abundant element in the universe? by ChickFleih
Spectroscopy in general. Then understanding nucleosynthesis when a star goes supernova.
Spectroscopy enables the observation of emission and absorption wavelengths of objects. The spectroscopy pattern can be determined in a lab with the respective elements.
Oxygen is in close contention with carbon it appears.

Reply to How do giraffes breathe? by NimishApte
As I recall from my human physiology class, it is called tidal volume. The game is to be able to have more volume in the lungs than the trachea. And that is pretty easy to do. Giraffes do have pretty big chests. And the next area to think about is the rate of ventilation. One is able to test this for themselves. How long can nominal breaths be skipped before needing a full breath to recover? You can go for a pretty long time taking every other. So that indicates that a single breath may have more O2 than needed as well as the capacity to take CO2. And so partial mixing of the last and next breath works. It is surprisingly complex.
As far as pressure, outside and inside the giraffe are the same pressure. And so it is a matter of muscles moving gas in a manner similar to a billows. But the diaphragm does the work via a pressure differential by expanding and contracting the chest cavity causing the pluera that contains the lungs to pull the lungs open.
What is cool is if you breathe sulfur hexafluoride, it is heavier than air. And so it doesn't mix. And it is difficult if not possible to ventilate. And so drowning! Unless you hang yourself upside down.
That is the extent of my recollection of that chapter. Good Q! Hope someone more up to date can correct me.

Yes, which is why various organizations have tried various endurance projects to see what happens. The ill fated biospheres immediately jump to mind. There is this one: https://www.hi-seas.org/
When combining the results of them with economic reality and the willful ignorance of most humans, one can easily jump to the bad news: Humanity will not be colonizing anything.

For me it is tremendously problematic regarding this topic. The amount of interest and time and money going into UAPs is at the cost of the things that could easily identify life in the universe.
Everyone makes noise about UAPs so the govt and NASA does something.
But why isn't that action resulting in another space telescope? Funding of a breakthrough challenge? Educating the next generation of theoreticians?
I believe the intense interest in UAPs is due to a subtle psychology: The kids are scared of the future and hope to see proven evidence that there is an in-Universe savior.
