Should We Wipe Out Disease w/ Genetic Engineering-Kurzgesagt
Ethics doesn't even come into the argument until we know whether it will actually work, and work without any negative consequences.
There are just too many variables in nature to test something like this completely in a lab.

Is Science Reliable?
Science "works" when scientists bother to actually try to replicate claims, no matter how bizarre they may be. And as this video and my comment shows, that's not happening in a number of scientific fields. Which is really, really bad for human knowledge and society in general, as billions of dollars and countless work-hours get wasted since researchers base future research on what turn out to be unreliable past claims.
The "extraordinary claims require extraordinary evidence" flies in the face of everything the scientific method espouses. Evidence is evidence. It is not supposed to matter who finds the evidence. Someone who is famous in the field should not be given more benefit of the doubt than someone who is not, yet that is exactly what happened in Shectman's case. He was removed from his lab and an actual expert in the field, Linus Pauling, verbally abused him for literally decades.
That's not how science is supposed to work at all. If someone finds evidence of something that contradicts current theory, you're supposed to look at their methodology for flaws. If you can't find any flaws, then the scientific method demands you attempt to replicate the experiment to validate it. You're not supposed to dismiss evidence out of hand because the person who found it isn't a leading expert in the field. In Shectman's case, other labs replicated his results and the "experts" still wouldn't budge... to this day in fact Pauling refuses to admit he was wrong.
Conversely, there are too many papers out there now with shoddy methodology that shouldn't even be published, yet because the author is a name in the field they somehow make it into top-tier journals and get cited constantly despite the dubious nature of the research. Again, that's not how science is supposed to work.
"Spurious bullshit," as you called it, is not being weeded out. Rather it is being foisted on others as "fact" because Dr. XYZ who is renowned in the field did the experiment and no one looked closely enough at it or bothered to try to replicate it. The spurious bullshit should be getting weeded out by actual scientific testing (like the studies in the video that were found to be unreliable) and not by mob mentality.
You can find examples of that throughout history, I think it's how science has always worked. You can sum it up with the saying 'extraordinary claims require extraordinary evidence' - when something has been so reliable and proven to work, are you likely to believe the first, second or even 10th person who comes along saying otherwise?
If you are revolutionary, you go against the grain and others will criticise you for daring to be different - as did so many geniuses in all kinds of different fields.
I think that's completely fair, because whilst it sometimes puts the brakes on breakthroughs because of mob mentality, it also puts the brakes on spurious bullshit. I'd prefer every paper be judged entirely on merit, but I have to accept the nature of people and go with something workable.
Who Pays on a First Date?
That thing about "best friend"? I have been saying that EXACT THING for years.
And not just about who pays for a date. It is for all aspects of the relationship. If I wouldn't put up with certain crap from a friend, why would I from a fella?
Side note -- never have I been in an abusive relationship. I wonder why that is?
But I know I am wired differently.
Long before feminism was a big important concept to me, I went on my first date with a young man I didn't know well.
I was 13 years old, in 1967. We went to a matinee at the local movie theater. Fifty cents a ticket.
I remember standing behind him in line, as he awkwardly paid, and I awkwardly didn't know what to do or say.
And my main thought was -- I have a job. I can afford my own ticket. (I cleaned test tubes in the junior high science lab. I still have sense memories of moldy agar in a petri dish.)
I never got over that. I still feel that way. Go ahead and treat me to something special that you can afford. Next time, it'll be my turn to pick the activity and I'll pick something I can afford.
I was lousy at dating. But I was clear about the basic equality necessary in order to respectful to both of us.

Vantablack can make a flat disk of aluminium float on water
Probably, but there are all kinds of clear coating. They could develop one with minimal reflective properties and minimal absorptive properties, but you're right, even then it would decrease the effectiveness, but maybe not so much that it would lose it's usefulness.
I think in most applications, the nano fibers are encased in resins or other chemicals that cause them to clump together, making them much safer (note that I don't say "making them safe").
In pure powder form, yeah, they're a bit scary to have something that can float in air that can also burst cell walls. I always used a facemask and gloves when I was in his "lab", and even so I'm sure I was contaminated. Now I wish I had worn a full anti-contamination suit.
Clearcoating this stuff would remove its blacker-than-black properties. It would then start to reflect light. At which point, why would you favor this expensive shit over regular paint? I haven't seen details on how the sprayable Vantablack is applied, but if it were mixed into a liquid for application, it would have the same problem, unless, somehow, the surface of the hardened material were burnt away, evaporated off, or chemically reduced so that the carbon material could protrude from the substrate, that may allow the light absorption properties to persist. But I don't know how they accomplish that, other than they say it's a complex process that requires a specialist. I still wouldn't try brushing up against it, just like I wouldn't try sitting there inhaling paint fumes after painting a car. There's a reason precautions are taken in that process as well. I just know that something small and damaging enough to burst cell membranes sounds like something I wouldn't want in a product I'm handling with direct contact with my skin, or with any remote possibility of it rubbing off and getting into the air.
RetroAhoy: Quake
I still remember when I downloaded qtestx86 for Linux and playing it in a college's computer lab's computer with no sound card on LAN. It was on a Sunday night too. It was SO rad.![](https://videosift.com/vs5/emoticon/teeth.gif)
*quality Quake is a game I will never forget and always appreciate. New Doom is awesome, but still - no where as immersive as Quake was when it was first released.
Can You Solve the Bridge Riddle?
It doesn't matter if you or the lab assistant go back first after the first crossing, though - the line "you, as the quickest, run back with the Lantern" doesn't make sense.

If you had a fear of elevators before...
There was a meth lab on the 6th floor.
Just sayin.
How did that craziness get embedded in your brain.
Dog assists in treat reward
If you ever need to give a dog a pill, just stuff the pill into a spoonful of peanut butter. We did it for 14 years with our lab.
Why Expiration Dates Are Bullshit
If the sour cream's not moldy, I still eat it.
Also good to know that PSU can freeze almost anything. I wonder what kind of refrigeration system they're using using in their labs?
