Ten Medieval Discoveries That Shaped How We Understand Sleep
"When we think about the history of sleep science, the story is often told as a leap from ancient Greek philosophy to modern medicine. But a new study shows that medieval physicians made several profound and interesting discoveries when it came to how we sleep."

Millions of People Depend on the Great Lakes’ Water Supply. Trump Decimated the Lab Protecting It.
—
The Trump administration’s slashing of budgets and staff have Great Lakes scientists concerned that they have lost the ability to protect the public from toxic algal blooms, which can kill animals and sicken people.

The moon landing conspiracy theory seems like old intrigue, but it’s estimated that as many as 10% of Americans still don’t believe we landed on the moon. We consider why the “moon hoax” belief has been difficult to shake on the latest Big Picture Science.

PRESS RELEASE:
A new study led by SETI Institute scientist Matija Ćuk suggests Saturn’s largest moon, Titan, formed from a collision between two older moons—and that this event may also be linked to the formation of Saturn’s iconic rings.

I am honored to share that I’ve been nominated for an Emmy as host of PBS’s Serving Up Science - a series funded by the National Science Foundation.
This recognition is a testament to what federal science funding & public media can achieve when we invest in #science, education & evidence-based storytelling.
And it’s a reminder that curiosity matters & there is value in making science understandable & available to all.
If this resonates with you, I hope you’ll support science agencies & PBS.
Trump’s War on Measurement Means Losing Data on Drug Use, Maternal Mortality, Climate Change and More
—
By slashing teams that gather critical data, the administration has left the federal government with no way of understanding if policies are working — and created a black hole of information whose consequences could ripple out for decades.

For the first time, researchers have imaged individual "itinerant" (free-floating) atoms and observed the way they interact.
How these sodium & lithium atoms behave depends on their spin state: We can directly witness the effects of quantum spin here. Amazing!

💣 💥 How the #Military_Industrial_Complex Affects OUR #POLLUTION_CRISIS | #ROOT_CAUSE OF MAJOR #POLLUTION IS #MILITARY_EMISSIONS [aka #MAN_MADE POLLUTION ??]
THE WEF (NAZI) FEAR MONGERS CONVENIENTLY LEFT OUT THE ROOT CAUSE 99.99% OF CLIMATE CHANGE = #USA AND #PROXY_WAR = #MILITARY_EMISSIONS!!
1. VIDEO: https://youtu.be/9id-a1Zm_0I
One of the Largest #EMITTERS of #POLLUTION (aka Climate Change) is the #Military and therefore the NEXT STEP is that we NEED TRANSPARENCY of Military Emissions AND THOSE EMISSIONS (POLLUTION) NEED TO BE #REDUCED ...2 decades ago!
What is a real threat is climate change’ — This U.S. Army vet is calling out the military for being one of the ‘largest emitters’ of carbon emissions.
The potential climate impact of the War on Terror is staggering, according to U.S. Army veteran Erik Edstrom. Edstrom is a West Point graduate, author, and former U.S. Army infantry officer who got out of the military after serving Afghanistan to study climate change and finance at Oxford University. Edstrom says the 20-year-long Afghanistan War contributed enough carbon emissions to kill multitudes of people. His assessment is based on studies such as one published in Nature Communications, which estimated that approx 4,400 metric tons of CO2 emissions is enough to kill one person.
The U.S. Department of Defense is required to report its energy use to the Department of Energy’s Federal Energy Management Program. In FY2020, total estimated DoD greenhouse gas emissions based solely on fuel usage data were more than 51 million metric tons of CO2. That figure includes emissions from standard day-to-day operations as well as emissions from non-standard operations such as combat support, law enforcement, emergency response, and spaceflight. Edstrom says there’s more to be concerned with than just operating emissions.
Edstrom says the U.S. Department of Defense budget, which in fiscal year 2021 was more than $703 billion, is bolstered by fear. He thinks Americans’ fears are misguided. Edstrom thinks the future military will be more electric, but says requiring the military-industrial complex to report the full scope of its emissions, beyond just fuel usage, is a crucial step in getting there.

“I listened to NSF staff say DOGE had the authority to give thumbs up or down to grant applications which had been systematically vetted by layers of subject matter experts.
Our closed-to-the-public deliberations were observed by Zachary Terrell from the DOGE team. Through his Zoom screen, he showed more interest in his water bottle & his cuticles than the discussion. Terrell..accessed the NSF awards system to block the dispersal of approved grants.“

Scientists find the best crops to grow during the apocalypse

The Four Horsemen, from The Apocalypse
by Albrecht Dürer (German, 1471–1528)
I am struck again by the unwillingness of people who believe in "entanglement" and "non-locality" to actually PERFORM A TEST that I suggest. They merely want to debate. They simply WILL NOT run an experiment, nor will they go through Bell's logic with some other problem that proves Bell had no idea what he was doing.
THEY ARE NOT SCIENTISTS.
Scientists are people eager to perform tests! These people not only do not show eagerness, they resist, resist, resist.
