<p>It's more about the indirection, but it's a matter of taste. Whales blow bubbles to sleep. Humans stink to thermoregulate. We blow air to metabolize. Cars rumble to propel themselves forward. In each case there's a missing mechanism (buoyancy control, perspiration, respiration, internal combustion) which scientific articles generally put right in the title.<p>But I agree with you, better that scientists provide something for everyone. This is a good press release (it's not really journalism if it's coming from the university press office).
The other very nice thing they did is link the original article in the first words of the release, although I would have made the hyperlink text "A new paper from University of St Andrews and Université de Neuchâtel" to make it clear that the paper is there. Hyperlinks are cheap and a lot of science is free to access, there's no excuse to leave that out.</p>

<p>Indeed.<p>This isn't a particularly bad case. I think both are often useful, and this headline isn't wrong, I just assumed the bubbles had some direct use and found the scientific title more clear there.</p>

<p>Oof, sorry if that was misleading.<p>Maybe I'm overly fixated on the "to" in "to achieve": the whale doesn't care about the bubbles, they serve no important purpose in helping them sleep, it's just what happens when you vent air under water.<p>It's also kind of a nitpick, but the scientists refer to <i>resting</i> whales, but specifically state that they don't know if they are sleeping. I guess getting a proper EEG on a sperm whale is another scientific frontier.<p>Edit: An <i>awesome</i> scientific frontier: honestly if anyone deserves my tax money it's the grad student trying to figure out how to measure brain waves in a submerged oceanic whale.</p>

<p>The title of the original article [1] is a lot more clear:<p><pre><code>    Buoyancy regulation through modulation of onboard gas volume by resting sperm whales
</code></pre>
They don't "blow bubbles" to sleep vertically, they vent gas to regulate their specific gravity. This allows them to sleep vertically below the surface. The scientists measured the gas release by listening for bubbles, but they did a lot more: they actually modeled the buoyancy of whales and compared it with data.<p>If you've done any scuba diving (or swimming) you're familiar with this method of buoyancy control. And most fish accomplish on actively transporting gas between an internal bladder and their blood.<p>The difference is that whales have no way to refill their lungs while submerged, which is why their dives start deep and slowly drift up: as long as they are drifting upward the volume in their lungs is expanding in response to decreasing pressure. So the bubbles are essentially a way of pumping the breaks, which is apparently something they can do in their sleep (if they are in fact sleeping).<p>Is anyone else slightly annoyed by the cutesy title? Of course I recognize that the meme economy runs on this stuff, so maybe it's just nerds like me.<p>[1]: <a href="https://dmscdn.vuelio.co.uk/publicitem/61eae467-9527-4922-b967-b5d362f12998" rel="nofollow">https://dmscdn.vuelio.co.uk/publicitem/61eae467-9527-4922-b9...</a></p>

<p>I feel like LEO is a convenient speed to know if you are someone who often asks "how fast is that". At Mach 23 it's a lot faster than sound, and on the slow side of "how fast space stuff moves".<p>Of course it's still 3 orders of magnitude slower than galaxy collisions, which themselves are colliding at roughly 1% of the speed of light.</p>

Local issues that concern a few thousand people can be (and often are) resolved by direct democracy.<p>I guess I could argue that putting a stop sign at a particular intersection in rural Kansas could concern me, even though I don't live in Kansas, but I think very few people would make that argument in good faith.</p>

<p>Also so that it can make the retailer money. The studio might not want to piss off the retailer, which they would do by pulling the physical copy (or selling it at the OEM price directly). There are cases where retailers will de-list some products in retaliation.<p>What's interesting to me is that game studios have less to loose here than other OEMs. With equipment like shoes, outdoor gear, or cars, having the physical product out in stores does a lot to sell it: you have to try on shoes, driving a car builds attachment, it's also nice to check the build quality of your tent or whatever.<p>With games, you generally just have to play it / read the reviews, and you can trial it directly at home in a lot of cases.</p>

<p>In the opening scene a scientist argues once the ambient temperature of some region is 37°C we'll all get eaten by fungus. It will evolve to live at body temperature.<p>There are some precedents for this: hibernating bats lower their body temperature to that of a moldy environment, and are getting infected with a fungus which kills 90% of them in some cases [2]. Logic goes that raising the ambient temperature could be the same (with some evolution thrown in) as lowering our body temperature.<p>Is it credible? No idea, not that kind of scientist.<p>[1]: <a href="https://www.youtube.com/watch?v=OLNagvJHl3g" rel="nofollow">https://www.youtube.com/watch?v=OLNagvJHl3g</a><p>[2]: <a href="https://en.wikipedia.org/wiki/White-nose_syndrome" rel="nofollow">https://en.wikipedia.org/wiki/White-nose_syndrome</a></p>

<p>I'm probably missing something. This would seem a bit problematic for some organizations that put Switzerland on the world stage, e.g.<p>- The UN<p>- CERN<p>- The Red Cross<p>- The WHO<p>- The World Economic Forum<p>- ETH Zurich<p>There are probably a lot of others I'm missing.<p>I'd imagine international banks also benefit from recruiting foreign nationals to do business with their home countries, and not just because there's a shortage of domestic labor.
The whole point of these organizations is to be the <i>headquarters</i> of a much larger international project.<p>I guess maybe there will be a lot of weird exceptions if this were to go though. Otherwise, good luck sourcing your diplomats from entirely Swiss people.</p>

<p>I'm not a lawyer, I program.<p>My understanding is that Civil Law (most of the world excluding UK, US, AU) is like a program: you feed it a situation, it outputs a decision, every once in a while you edit it.<p>Common Law (UK, US) isn't really a program, but you could stretch and say it's a state machine that has been running since the country started. Every interaction sets a new precedent and changes the state. But the programming analogy falls apart because no one in the right mind would design such a program.<p>LLMs might actually be the best example of such a program though: Common Law is basically one long chat with an LLM, hundreds of years long.<p>Before LLMs came along, a Common Law system seemed to have a finite time limit before it's co-opted by wealthy people with the resources to read the whole history. Now I think maybe can push it a bit further.<p>But it's still a terrible program.</p>
