It's approaching troll event horizon, with trolls trolling trolls who troll trolls trolling other trolls. Ridiculous.

On one hand, I'd welcome empirical evidence that black holes actually exist, even if it requires every troll on Earth to do it. OTOH, 4chan has spewed forth many notable elements of on-line culture, so its loss would be lamentable. Sorta.

I'm conflicted.


Octopus-Inspired Robot Matches Real Octopus For Speed 71

KentuckyFC writes: Underwater vehicles have never matched the extraordinary agility of marine creatures. While many types of fish can travel at speeds of up to 10 body lengths per second, a nuclear sub can manage a less than half a body length per second. Now a team of researchers has copied a trick used by octopuses to build an underwater robot capable of matching the agility of marine creatures. This trick is the way an octopus expands the size of its head as it fills with water and then squirts it out to generate propulsion. The team copied this by building a robot with a flexible membrane that also expands as it fills with water.

The fluid then squirts out through a rear-facing nozzle as the membrane contracts. To the team's surprise, the robot reached speeds of 10 body lengths per second with a peak acceleration of 14 body lengths per second squared. That's unprecedented in an underwater vehicle of this kind. What's more, the peak force experienced by the robot was 30 per cent greater than the thrust generated by the jet. The team think they know why and say the new technique could be used to design bigger subs capable of even more impressive octopus-like feats.

Probably. Funerary practices in that part of the world are very home-centered, generally administered by the grieving family. That's a major current transmission route, and its emotional and traditional base gives it resistance to quarantine pressures. No one is just going to pile corpses outside waiting for the body cart, if they've spent weeks locked away caring for their dying loved one.

Dealing with the dead is a big part of epidemic management, and "doing it right" (to minimize infectiousness) is expensive, as well as insensitive to the survivors. So yeah, the dead will continue to infect the living, until it burns itself out, or until someone imposes draconian responses.

Corollary: Anything done late by Apple wasn't cool until Apple did it.

Corollary corollary: Unless Apple claims it was never done before Apple did it, objective reality notwithstanding. Because it didn't count, or the RDF makes the faithful forget, or "No true Scotsman", or whatever.

Harvest their organs for the long organ donor list and they'll have contributed to society for once in their now terminated life.

Certain intelligent people have already explored where that idea ends up.

Executive summary: you better never get caught jaywalking, because there are dozens of people who think they have a claim on your vital organs thay you do.

You mean KC-10. The KC-135 platform is based on the ancient Boeing Dash 80 airliner prototype, the forebear of the 707.

The US Air Force is contemplating retiring the KC-10 as it takes on the new KC-46 (tankerized cargo Boeing 767) so that they can continue to maintain only two tanker types in the fleet.

If you think like a cell in a Corporate Person, it's a critical distinction.

It's why you can't sentence a corporation to death, as much as it might be deserved.

So, yes. It's a distinction that makes no difference to the user, but every difference to the corporation.

And, at the end of the day, we all know whose interests the corporation is looking out for.
