Re: Evolution Tells Us We Might Be The Only Intelligent Life in the Universe
I agree.
Given the conditions for life to develop it did so. Those conditions might be rare, but the galaxy is a very big place and the universe is for all practical purposes infinite.

The $200M Machine that Prints Microchips: The EUV Photolithography System
The first 12 minutes cover the basics. The next ten minutes get into how the light is generated.
The degree of precision of these machines seems almost impossible. It shows that if there is a financial incentive, the free market will find a way.
There are not many companies that have these capabilities, and a manufacturing plant costs billions of dollars to build.
I saw a headline today about the first 2 nanometer chip being manufactured. From what I understand, we are approaching the limits of what physics will allow.

How iPhone Proves Electric Cars Will Win
https://www.youtube.com/watch?v=BMEDY2xGC8Y
For the moment, gasoline is much more energy dense and a more convenient way to power your car. I don't think that the laws of physics will ever allow battery power to be as convenient.
If we run out of oil, and we will, I think that we will still use synthetic fuels.
Electric cars are great if all you want to do is make short trips.

Windfall
When I hear the word "windfall", I think of a big pile of cash. However, that wasn't its original meaning. If a storm were to knock down a tree, the wood would be easier to harvest, so it is called a windfall. Likewise, fruit that falls from a tree is easier to harvest, so it is called a windfall.
What's BETWEEN the Atoms? Feynman's Answer Will Break Your Brain
I knew all this but I like the way he explains it.
In 420 BC Democritus argued for the existence of atoms.
"Democritus's argument for the existence of atoms hinged on the idea that it is impossible to keep dividing matter infinitely - and that matter must therefore be made up of extremely tiny particles"
Democritus thought that the universe consisted of atoms and the voids between them.
Until relatively recently, people thought that atoms were invisible. J.J. Thompson, Marie Curie, and Earnest Rutherford showed that atoms could be divided. It took a while to discover protons and neutrons, and people thought that these were also indivisible. It was later discovered that protons and neutrons were made of up and down quarks.
One could argue that quarks and electrons are the smallest (fundamental) units of baryonic (quark) matter, but this is misleading. Every type of subatomic particle has a field associated with it. A field is something that has a value at every point in space. That value represents that amount of excitation of the field at a particular point. There is likely some energy everywhere, because the fields have been shown to be like tiny ripples on a vast ocean, but if the energy is low at any point in space then not much happens. However, if the energy reaches a certain threshold, then a particle exists at that point.
The Standard Model of Particle Physics has 17 fundamental fields. (There is recent new evidence that Dark Matter may be an unknown type of particle. If so, it might require a new type of field.) Some of these fields interact with each other like the way the electric and magnetic fields can make particles move. These interactions between the fields create the laws of physics, although there is currently no quantum theory of gravity.

Scientists may have finally 'seen' dark matter for the 1st time | Space
it would mark the first time humanity has 'seen' dark matter. And it turns out that dark matter is a new particle not included in the current standard model of particle physics," Totani said. "This signifies a major development in astronomy and physics."
While Totani is confident that what he and his colleagues have detected is the signature of dark matter WIMPs annihilating each other at the heart of the Milky Way, the scientific community in general will require more hard evidence before the book is closed on this nearly century-old mystery.
"This may be achieved once more data is accumulated, and if so, it would provide even stronger evidence that the gamma rays originate from dark matter," Totani added.

Heavy Metals in your Chocolate: The Best & Worst Brands
The California Proposition 65 standard is not a safety standard, but a labelling standard. The FDA allows higher levels of heavy metal contamination.
I can no longer find the Sam's Choice brand of dark chocolate. The 72%, which according to the video has too much cadmium, shows up on the Walmart site, but it is out of stock.
Walmart has replaced the Sam's Choice brand with their "Better Goods" brand. I was buying this, because it is about a dollar cheaper, but I can't find any information about its heavy metal content.
According to the video, if I wanted to play it safe, I would buy the Giradelli 86%.

Humidifiers: Simpler is better?
https://www.youtube.com/watch?v=oHeehYYgl28
During the cold weather, I have trouble with dry skin, so I asked my doctor if I should get a humidifier. He thought that it would be a good idea, and he said that he uses one.
Speaking of "swamp coolers", they are very popular in Utah where the climate is very dry. My house came with one, and it did a very poor job of cooling my home. So I had an AC system installed.

Scientists uncover a hidden protein behind deadly mystery diseases
Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten dangerously, leading to serious diseases.
Stanford study reveals why COVID vaccines cause rare heart inflammation
Myocarditis, which is inflammation of the heart, occurs in about one in 140,000 people who receive the first dose of the vaccine and one in 32,000 after the second dose, according to a Stanford press release. Among males 30 and younger, that rises to one in 16,750.
Symptoms of the condition include chest pain, shortness of breath, fever and palpitations, which can occur just one to three days after vaccination. Another marker is heightened levels of cardiac troponin, which indicates that the heart muscle has been damaged.
They found that those with myocarditis had two proteins in their blood, CXCL10 and IFN-gamma, which are released by immune cells. Those proteins then activate more inflammation.
"We think these two are the major drivers of myocarditis," said Wu. "Your body needs these cytokines to ward off viruses. It's essential to immune response, but can become toxic in large amounts."
"One of the most striking findings was how much we could reduce heart damage in our models by specifically blocking these two cytokines, without shutting down the entire (desired) immune response to the vaccine," Wu told Fox News Digital, noting that a targeted, "fine‑tuning" immune approach might be enough to protect the heart.
"This points to a possible future way to prevent or treat myocarditis in people who are at the highest risk, while keeping the benefits of vaccination," he added.
The findings were published in the journal Science Translational Medicine.
"This is a very complex study," Fox News senior medical analyst Dr. Marc Siegel told Fox News Digital. "Myocarditis is very rare, and the immune mechanism makes sense."
"Myocarditis is worse with COVID — much more common, and generally much more severe." Wu agreed, adding that COVID infection is about 10 times more likely to cause myocarditis compared to mRNA-based vaccines.
The researchers emphasized that COVID-19 vaccines have been "heavily scrutinized" for safety and have been shown to have an "excellent safety record."
In rare cases, however, severe heart inflammation can lead to hospitalizations, critical illness or death.
"mRNA vaccines remain a crucial tool against COVID‑19, and this research helps explain a rare side effect and suggests ways to make future vaccines even safer, rather than a reason to avoid vaccination," Wu said.
"The overall benefits of COVID‑19 vaccination still clearly outweigh the small risk of myocarditis for nearly all groups."
