Unidentifiable stellar object stumps astrophysicists

Today we’ll talk about Einstein, who was right again, metals that heal, a new type of stellar object, a quantum drum, how conscious awareness comes about, maybe, a better way to tell apart alien signals from boring human signals, a hot spot on the moon, illegal trade of hazardous chemicals, and of course, the telephone will ring.

I've been re-watching some of Sabine's older videos lately, and I'd like to compliment on her improved English. It's not that her older English ability was bad, but it has improved. She sounds completely comfortable in it today. Congratulations Sabine.

In regards to the fallout maps, I was in grade school in the late fifties. During the 57-59 time period, we were asked to donate our ‘baby’ teeth. Cesium looks like Calcium. By collecting the teeth, they were able to conduct a mass autopsy on the first 8-10 years of population. I lived in St. Louis, MO. The Philippe map shows a ‘hot’ spot in southern Illinois and Missouri and western Kentucky. There are several small signals on the east coast. I’m didn’t hear how the authors identified fallout. It’s disjoint areas, which makes me suspicious of the quality of the data. It’s interesting that it took 60 years to report their findings.

I really appreciate your effort to deliver such a great work with high credibility and reliability, Thank you Dr. Sabine!

[LakersSocal]

Wow almost a million subs. This channel has come a long way.

With all the annoyance & trepidation that Sabine shows each time she answers the telephone, it's surprising that she continues to be so enthusiastic each time she says "and of course the telephone will ring."

[ktrethewey]

The best science news channel by far! Thanks Sabine!

The way I heard it, scientists in the northeastern United States were concerned about widespread fallout from open-air nuclear tests.
They took detailed air samples and actually discovered airborne plutonium that could have only come from the nuclear tests in the southwestern United States. Their work helped get the first nuclear test band treaty passed, which mandated that all nuclear tests had to be conducted underground.
But they also found surprisingly large amounts of lead in the air. This eventually led to the end of the use of leaded gasoline.

The Final Fantasy VII Victory Fanfare soundbite has cemented me as a loyal fan of Sabine for life.
Whether it is Sabine herself or a paid editor it don't matter. Loyalty comes in strange ways.

[seionne]

Whoever does the sound effects, I love you almost as much as I love Final Fantasy

[saelesbonsazse]

There's a cool story of how Kodak accidentally detected nuclear fallout hundreds of kilometers away from secret testing sites, because radiation damaged their sensitive XRay films. Cool, but also creepy!!

I appreciate you and the other science educators efforts to help us be informed. Yours I like for the quick and easily digested updates. The phone calls are a great running gag too 😁. Keep up the good work. For unhoused people like myself it is a huge help with keeping informed while having extremely limited resources.

Is it just me or is there an extraordinary amount of interesting topics this week? I needed this since I just heard the news about what will happen in the Atlantic Ocean by 2025 if things don't improve.

Picking two topics from this week's episode to comment on here, I'll have to leave out the two that work so well as daydream material of my favorite sci-fi novel that's writhing itself in my head- manufacturing space stuff in space using cold welding on the dark side of the moon.

As for "how does consciousness work" (that's funny because it's about knowing something about the thing you know stuff about with) it introduces a new model complimentary of a previous model both of which I previously knew nothing about. Anyway, lots of corollaries there with theoretical linguistics about the origins of language.

Although it was introduced as some sort of MEMS (Microelectromechanical systems) device you might find in a smartphone (which I'm really interested in) the "laser cooled quantum drum" made my day thinking of how lasers could be used to phase oppositionally vibrate materials to make the atoms of those materials become more still thus cooling them. The idea of reducing lasers to microscopic size to cool miniscule pieces of various materials to measure environmental effects is really exciting. Although reducing the size of the laser wouldn't be necessary, it would seem reducing it to be small enough to be directly effected by the temperature of the target material could reduce a lot of the internal circuitry.

The transitional sound between subjects caught me until I learned that new episodes will be in audio-only for other platforms.

Way to go!

Another good video Sabine, always good to hear you. I love studying astrophysics. Travis X

[catserver]

I am totally referring to my next disagreement with a loved one as "fatigue cracks" lol.

[robward]

its a testament to how good you are at the telephone joke that it only now really occurred to me youve been going the same gag for like a year, and its never felt forced

[goacoa]

I pissed myself laughing at 6:37
"Naturally they named it GPM J1839-10 and asked their mum if they could keep it"
😅😂😂

[myfriendscat]

Wonderful combination of information and, dare I say it, entertainment. Her Pixie's reference suprised me. I was a drummer in a punk-band in early 90s and our mindset was very a pixyish.

[neilgiri]

Waiting for your take on superconductor which works in Room temperature and ATP . Thank you..

Hello Sabine, thank you so much for these news videos. You have the best science channel on YouTube!
