Brown Bears

Bears scare me more than most things in nature.  I would look like a light lunch to a bear.

People are braver than they should be around bears.

The Night Texas Hit 140°F (60°C) During a Thunderstorm

The atmosphere is inherently turbulent, so it doesn't surprise me that weird weather can happen.

I don't think that humans can survive 140 degrees for four hours.  Reportedly, people took shelter in storm cellars and basements and used wet cloths to cool off.  

I'm not sure how many people had air conditioning in 1960, although it became more common in the 60s and 70s.  

This is a rare meteorological event.  If it happened today, we would probably survive because of AC, although we might be pretty hot for a while.

It goes without saying that unnatural events can produce deadly heat.  I'm thinking of nuclear weapons.  In the (unlikely) event of a nuclear blast, you should stay indoors, preferably in a basement for about 3 days.  Reportedly, radiation from fallout will drop by 99% in 49 hours.  However, being indoors doesn't guarantee your safety, and reportedly you have about 45 minutes after the blast to evacuate the affected area, which in theory could spread over a large area.  Since nuclear weapons produce an EMP, it is possible that nothing electrical will work.

Just as a precaution, I keep a supply of bottled water, enough to last a few days.

How long would you survive with no DNA?

Our cells need RNA to perform their functions, and they make RNA by transcribing DNA.  The RNAs are used up very quickly because they act like instructions from the cell's nucleus to the cell's machinery.

This Food Component Cuts Visceral Fat in Half (Science-backed)

https://www.youtube.com/watch?v=jII_IDTCw-o

I'm not sure how to eat this food, and 40G seems excessive.

https://youtu.be/ZkosHWNSLc4?si=i7ZZadzYQrDGKq2h

Likewise, he recommends 40G fiber.  Again, this seems way excessive.  A 12 oz package of mixed vegetables, which claims to be 4 servings, has 12G of fiber per package.  I like eating vegetables with something that tastes good, like chicken nuggets, chicken strips, or ravioli.  

I also get fiber from fruit.  I try to eat an apple every day, because doing so reportedly can lower cholesterol.

Too much of either substance will have intestinal effects, like gas, because they are broken down by gut bacteria.  I've been trying to eat fiber to deal with constipation.

Large-scale Vitamin D study on Telomeres, an important Marker of Aging

I'm concerned that the study doesn't control for the Omega-3 intake, although taking both sounds like a good idea.  I'm already taking Vitamin D.   However, I'm not a doctor nor a medical expert.  

I'm also concerned that he doesn't provide a link to the study.  I found the article on the The American Journal of Clinical Nutrition website:  https://ajcn.nutrition.org/article/S0002-9165(25)00255-2/abstract

I believe in, "Trust, but verify".  I would like to see more studies.  

According to Google AI...

"Yes, The American Journal of Clinical Nutrition (AJCN) is a highly reputable, peer-reviewed scientific journal publishing primary research, considered a top source in nutrition and dietetics, though it's published by the American Society for Nutrition (ASN), which receives funding from food/beverage industry partners, a point some critics raise regarding potential influence. Its high impact factor and publication of rigorous studies on topics like obesity, metabolism, and vitamins underscore its scientific standing. "

94% of the Universe is Gone Forever

https://www.youtube.com/watch?v=wMafg99BTm0

It seems pointless to talk about 2 trillion years from now.  Fifty thousand years ago, at the beginning of the Upper Paleolithic, humans appeared to get smarter, inventing new tools and the first permanent structures.  A million years ago our ancestors were Homo Erectus.  

A million years from now, and maybe much sooner, humans will look different and most likely be adapted for a new kind of existence, such as space travel.  A million years is enough time to evolve into a new species.

There is no guarantee that we will survive that long, but I have faith that people will find a way.  The Earth will only be able to support life for about a billion years.

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.

I only watched the first 2.5 minutes. He said that we have no evidence of intelligent life elsewhere in the universe, as if this were an important part of his argument. Although that statement is technically correct, the distances involved are so vast that it is unlikely we could detect their radio signals—or that they could detect ours.

If we look at the evolution of life on Earth, we see incredible resilience. Once life starts, it finds a way; it adapts.

There are many examples of convergent evolution, where unrelated species independently evolve similar traits. For example, complex eyes evolved multiple times in different lineages, and several unrelated species independently evolved crab-like body plans.

What evolution shows us is that it adapts to incentives. Creatures become faster because they need to. Animals that benefit from greater intelligence evolve it. Only a few species are intelligent, while most are not, for the simple reason that they do not need to be. Intelligence is energetically expensive, and it is often more efficient not to have it.

Once life begins, I think it has the potential to produce intelligence. If we could travel to another world with life, we would likely see an enormous variety of organisms. Some of them would look familiar, because the patterns that work here could also work elsewhere.

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.

https://www.youtube.com/watch?v=B2482h_TNwg

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.
