Sorry I can't point you at a reference, but thing is that the mitochondrial environment is a really bad place for DNA to live, so over evolutionary time some of the bacterial DNA moved into the cell nucleus. Mitochondria is now an "obligate parasite", though parasite is *really* the wrong term. (I can't think of the term for obligate symbiote.)

OTOH, I'm talking about the function rather then the physical pieces. This is probably similar how some of our DNA "moved into" the plants that we eat, so now we are dependent on them for vitamin C. But the result is that much of the DNA controlling the mitochondria now resides in the cell nucleus.

In those days all laptops were thick....

I got one at the time, and put OS/2 Warp on it. Was pretty happy with the small and light form factor. Of course we all know how Microsoft double crossed IBM on OS/2, so I didn't end up using it as much as I had imagined.

Because the laptop was small, you needed to keep an external CDROM drive attached via a flimsy cable, at least that's what I vaguely remember. The cable didn't inspire confidence.

Most popular laptops in the market ended up having a built-in CD/DVD drive and a larger spinning HDD, I'm guessing that was the minimal size bottleneck that also implied optimizing keyboards for size was meaningless: it could be as big as two drive bays side by side.

With laptops stuck at that larger size, the more complex and expensive engineering of the butterfly keyboard wouldn't make economic or practical sense to anyone.

But it was super cool though:)

Comment Re:WSJ source? (Score 1) 69

So I did some Googling because as the last paragraph hinted, there was a recall about this - ie switches were replaced (in 2018.) This is apparently what the people I heard talking about the issue were referring to (as an aside I find it surprising that you think all planes have the same switch, rather than a significant number of Boeings having a specific Boeing design for twin engine planes, etc)

As I said though, I'd have assumed this plane would have had its fuel cutoff switches replaced given all of this was 7 years ago.

This isn't gene line surgery. It's inheritable only along the female line. (But, yeah, mistakes WILL happen. Even normal mitochondria have a high mutation rate. And those with problems will be disadvantaged, and probably have no grandchildren. And if they do, only the granddaughters will spread the mutation.)

A point, but given the mutation rate of mitochondria, not a good one. More to the point, if it doesn't fix the problem, or creates a worse problem, the kids probably won't reproduce.

Also, since mitochondria are inherited almost only along the maternal line, it won't spread widely. It will be confined to the descendants in the female line of one family. (Sons may carry it, but won't spread it.)

Mitochondria from the father would be equally experimental. Mitochondria are almost never inherited from the father.

But, yeah, it's experimental. Some mitochondria don't play well with some nuclear DNA combinations. (Part of the mitochondrial DNA is stored in the cell nucleus.) But it won't create a "new genetic disease" because those things already happen once in awhile. It's just that it might not fix the problem. Presumably they check that before they do the implantation though.

You might get sentenced for not alerting by bozo judges.

It should be mentioned that this was a 2012 trial after a 2009 earthquake, and that all but one of the convictions were overturned on appeal. The one whose sentence was confirmed also had his sentence reduced and suspended. In Italy, convicts don't go to prison until after their first appeal, so none of the scientists served a day of their sentence.

The one that had his sentence confirmed, though not his punishment, had provided information in an interview that was scientifically invalid and discourage evacuation. Specifically, he told them that the many small quakes reduced the likelihood of a big quake by releasing pent-up stress, but the scientific consensus is that this isn't true because the amount of energy released by small quakes isn't enough to affect the energy of a big one, not unless there are tens or hundreds of thousands of small ones, and that a rise in the number of small quakes more often indicates increased probability of a big one.

I don't think he should have been prosecuted for what he said, but he really should have been more precise, and more responsible. A suspended sentence to make the point that scientists need to be careful and precise with their public statements in cases where lives are on the line is excessive, but it's not ludicrous.

Comment Re:Block china entirely (Score 1) 14

Given that China doesn't allow everyday citizens unlimited access to the internet, we can assume the only ones allowed out are bad actors like badbot, so blocking China entirely would be a net benefit for the entire world. We'd have to get the VPN operators to cooperate, which is near impossible since they'd sell their own mothers for a quick buck.

It would barely inconvenience them. These guys are well-funded. They'd just set up their own relays outside of China.
