Reply to comment by IronOk1931 in TIL about the NOAA Corps, the eighth federal uniformed service, alongside the six Military services and Public Health Service. It has just 321 enlisted officers, and operates 15 ships and 10 aircraft. by ex-apple

Yes the Marines count as their Own Branch. And now it’s the seven uniformed services:

Reply to TIL that +/- 42k years ago, the “Adam’s Event”, a reversal of Earth’s magnetic poles, may have led to the extinction of mega fauna, Neanderthals, and forced humans into caves as the earth experienced intense periods of cosmic radiation, solar winds, electrical storms, and drastic climate change. by GonzoVeritas

Original research article from the Adams Event team

Summary Article

Video, “Paleopocalypse!”, narrated by Stephen Fry

Summary:

The temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study co-led by UNSW Sydney and the South Australian Museum shows.

This dramatic turning point in Earth’s history – laced with electrical storms, widespread auroras, and cosmic radiation – was triggered by the reversal of Earth’s magnetic poles and changing solar winds. The researchers dubbed this danger period the ‘Adams Transitional Geomagnetic Event’, or ‘Adams Event’ for short – a tribute to science fiction writer Douglas Adams, who wrote in The Hitchhiker's Guide to the Galaxy that ‘42’ was the answer to life, the universe, and everything.

Abstract from research paper:

Geological archives record multiple reversals of Earth’s magnetic poles, but the global impacts of these events, if any, remain unclear. Uncertain radiocarbon calibration has limited investigation of the potential effects of the last major magnetic inversion, known as the Laschamps Excursion [41 to 42 thousand years ago (ka)]. We use ancient New Zealand kauri trees (Agathis australis) to develop a detailed record of atmospheric radiocarbon levels across the Laschamps Excursion. We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.

Reply to comment by NickSwardsonIsFat in TIL the legendary story about a janitor who came up with Flamin' Hot Cheetos was a lie. by Station_Emotional

NPR is definitely biased, which is annoying. I'm a conservative who literally used to listen to them every single day for years until the 2016 election cycle when their minds exploded. I took them off my preset for a while and decided to try them again in, idk 2018 or 2019 and that lasted about a week - so much bias it was like listening to anti-Fox news (which I also can't stand).

I just want unbiased reporting of news without opinion, and I can't even get it from public broadcasting. It sucks.

Reply to TIL Captain America co-creator Jack Kirby was drafted into the U.S. Army during WWII, landing at Omaha Beach in Normandy. When a lieutenant found out he was a comics artist, he made Kirby a scout who would advance into towns and draw reconnaissance maps and pictures, an extremely dangerous duty. by geekteam6

I still remember the episode Superman: The Animated Series dedicated to his memory as if I watched it yesterday.

Long live the king.

Reply to comment by malepitt in TIL that when you say a word many times over, and it stops sounding like a word, that is called 'semantic satiation.' by Bean_Superiority

"Of COURSE it's a really good question, you gibbering tit! She's Terry fucking Gross! Did you have NO idea what you would be asked about???"
Drives me absolutely BATSHIT. Just...shut up for a minute while you think up your answer, goddamnit. Glad it's not just me.

>Kirby was drafted into the U.S. Army on June 7, 1943. After basic training at Camp Stewart, near Savannah, Georgia, he was assigned to Company F of the 11th Infantry Regiment. He landed on Omaha Beach in Normandy on August 23, 1944, 2+1⁄2 months after D-Day, although Kirby's reminiscences would place his arrival just 10 days after. Kirby recalled that a lieutenant, learning that comics artist Kirby was in his command, made him a scout who would advance into towns and draw reconnaissance maps and pictures, an extremely dangerous duty.
