Tourniquets hurt like crazy if applied correctly. CPR should break ribs. Don't hesitate, act fast, save a life. I don't speak for any present or past employer.

@scottwestacre I didn't think that was controversial? It matches what I remember from a TV documentary.

Dust bowl. Pretty accurate.
Drought and heat caused the dust bowl era not farming practices. Farming practices exaggerated the result
Chris Martz@ChrisMartzWX
Okay. Let's have some fun. Whenever you bring up the heatwaves and drought of the 1930s, climate panic puppies are quick to dismiss them as “statistical outliers” that were caused by “unsustainable farming practices” in the Great Plains. This is cute, but it's not really true. The decade-long drought of the 1930s covered much of the United States and significant portions of Canada. The extreme heat in July-August 1930, June 1933, May-August 1934, June-August 1936, and September 1939 also covered much of the Continent. But the “Dust Bowl” itself was primarily confined to a relatively small area in northern Texas, the Oklahoma Panhandle, and western Kansas. In other words, farmers plowing up deep-rooted perennial prairie grasses and replacing them with shallow-rooted annual crops outside of places like Liberal, Kansas or Boise City, Oklahoma were not responsible for the heatwaves and continental-scale drought. Sure, those agricultural practices amplified drought conditions and, by extension, the intensity of heatwaves on a very localized basis, and they stirred up the dust storms that swept through the Great Plains, but those farming practices were not the actual cause the persistent drought or heatwaves during the 1930s. The drought was naturally forced by persistent La Niña conditions (similar to what has been occurring in recent years) in the equatorial Pacific Ocean and an unusually warm subtropical North Atlantic (Schubert et al., 2004; Seager et al., 2008). 🔗science.org/doi/10.1126/sc… / open-access: www7.nau.edu/mpcer/direnet/… 🔗journals.ametsoc.org/view/journals/… Below average sea surface temperatures (SSTs) in the tropical Pacific produced negative 500 hPa geopotential height anomalies over the tropics, which led to positive anomalies over the mid-latitudes. This created large-scale subsidence (sinking air) over the Plains, which suppressed rainfall for several years. Concurrently, a warm North Atlantic generated anticyclonic rotation in the mid-to-upper troposphere and low-level cyclonic flow that cut off moisture transport from the Gulf of Mexico (or America if you prefer; I'm not going to get into that argument with anyone) to the central United States, especially during the summer and fall. These two factors alone initiated the drought, as they had during the preceding centuries and also recently. In fact, severe droughts in the Great Plains typically happen about once or twice a century (Woodhouse & Overpeck, 1998), and occasionally have been so severe that they transformed the region into a de-facto desert with blowing sand. 🔗journals.ametsoc.org/view/journals/… Notably, multi-decadal droughts during both the 13th and 16th centuries exceeded the 1930s drought by intensity and duration, all naturally forced. A tree-ring analysis in Nebraska found that the 13th century Medieval drought lasted an incredible 38 years (Herweijer et al., 2006). 🔗journals.sagepub.com/doi/10.1191/09… / open-access: researchgate.net/profile/Richar… Land degradation only locally enhanced drought and heatwave conditions during the 1930s. It did not cause it, nor did it enhance those similar conditions exhibited elsewhere on the entire continent. In other words, you cannot simply dismiss the 1930s heatwaves and droughts because they are problematic for your narrative. It was almost entirely natural. It verifiably happened. And, it isn't going to be dumped down the memory hole so long as I am still standing, I can rest assure you of that.

@AdaMcVean @ScienceMagazine And now that I've read it, thank you. The story was concise and clearly told both what was interesting and what the key gap in the research was. I like to summarize science news each Saturday night on the ham radio, and it was a pleasure to mention your article.

@erect_deathbed @NASA_Johnson @NASA It's possible that's even part of the joke. One astronaut class named their successors The Penguins, implying that they wouldn't get to fly... And there were The Original Nineteen and TFNGs. A strong sense of humor seems to be an unwritten NASA requirement!
English
@NASA_Johnson @NASA platypus comes from greek where the plural form of "-us" is "-odes" unlike Latin derived words ("-i")
etymologically speaking the only correct plural of platypus is either "platypodes" (greek etymology, like octopodes) or "platypuses" (classic english|germanic pluralism)

Spring always reminds me of impressionism. So I've prepared a thread for you about amazing 🇺🇦 impressionist – Oleksandr Murashko. Enjoy, read, share 🌸🌷

@ukr_arthistory Very eclectic style.
The 3rd painting- a woman holding a bouquet of orange flowers- straight up reminds me of Egon Schiele.
My favorite is "Sundays". Love the light and shadow on the girl's white dress.
Thanks very much!

@dalsubfan @aakashgupta I remember those gas delays! I hope that they've either planned for it, or it's not relevant there.
English
When they did Dallas DART's tunnel, one of the major problems was the gas alarms going off all the time and shutting down the work as they hit tiny pockets of gas in the limestone. If I remember right they finally got OSHA approval to bypass the alarms as they proved it was not a threat. Automated machines removes all of this, doesn't it?

The real story is the $25 million per mile price tag they’re betting on.
Nashville’s own 2018 light rail plan priced at $200 million per mile. New York’s East Side Access cost $3.5 billion per mile. The LA Metro expansion is running $1 billion per mile. The Boring Company says it can build 13 miles of twin tunnels through Nashville for $240-300 million total.
That’s a 95% cost reduction from the industry average. If the number holds, it rewrites the economics of every transit project in America. If it doesn’t, a few hundred million in private capital evaporates and taxpayers lose nothing. That risk asymmetry explains why Tennessee said yes when LA, Chicago, Baltimore, and DC all said no.
The engineering gamble is wild. 12-foot diameter tunnels instead of 28-foot. Fully electric Prufrock machines that mine continuously instead of stopping every 5 feet to install lining segments. Zero people in the tunnel during operations. A machine that “porpoises” into the ground from a truck instead of requiring million-dollar launch pits and cranes.
Every one of those innovations has worked in Las Vegas sand. None have been tested in karst limestone, the geology that creates sinkholes, caves, and underground streams. Their own CEO said at the unveiling that Nashville would not be their choice if they were optimizing for easiest places to tunnel.
This tells you everything about what The Boring Company is actually trying to prove. Nashville is where the thesis meets the hardest possible geology. 50 inches of annual rainfall versus Vegas’s 4. Rock that creates underground caves and streams. They just signed a construction contract in Dubai too, meaning they need Nashville to work before the next project launches.
The internal memo from the governor’s office estimates 1 mile per month. The Boring Company’s website claims 1 mile per week. That 4x gap between political planning and corporate marketing will determine whether this finishes in 2027 or 2030.
Week 7, when Prufrock-MB2 arrives, is when this gets real. Two machines boring simultaneously through Tennessee limestone will answer the question the entire tunneling industry has been debating for a decade: whether a startup can actually outrun the physics that made infrastructure the slowest-moving sector in construction.
The Boring Company@boringcompany
Tunneling has begun in Nashville - we are 2.5 feet in! Looking ahead: - Weeks 1-3: Prufrock-MB1 launches and undergoes a series of tests and calibrations (low production) - Weeks 4-6: scale to high production - Week 7: Prufrock-MB2 arrives

She is Ukraine.
Long before the world began watching, Ukrainians were already defending their homeland with their lives.
This fight did not begin in 2022. It has been carried by those who refused to surrender their country, their identity, or their future.
Senior Soldier Olha Benda is one of many decorated Ukrainian service members who paid a devastating price in this war long before it made global headlines.
She lost her leg defending Ukraine against russia and still chose to return to service.
Her strength is not symbolic. It is lived. It is Ukraine.
While russians attempt to distort the past and rewrite their aggression, the truth remains in the stories of those who fought, bled, and endured when few were paying attention.
History does not begin when the world decides to look.
You can read more about her story in this 2018 article:

russians did not suddenly become evil in 2022.
