Everywhere I look, all I see is fking ants. All around the house and property and not only me. Seems like there is an explosion in the ant population this year and everyone is having issues with them. Fortunately they are common black ants and not red one's but they still get into everything.

Gonna need lots of ant traps

The earth's core produces constant heat. If you drill down you can extract this heat and have a constant source of hot water to create energy. The used water can be returned and reheated, so you have a constant loop of cool water going down and hot water coming up. To enable the extraction on an industrial scale, the oil and gas companies have the expertise to do the drilling. The product is green. The only risks are earthquakes. But these can be avoided and reduced to small quakes which are controlled if they occur.

In very primitive life forms, there are methods of exchange of genetic materials, between sexes, but it hardly resembles s*xual reproduction. But all higher forms, including even many plants, with exceptions, from a genetic viewpoint, resemble the egg and sperm deal seem in humans. So the advantages of this scheme go very far back and are everywhere. Except in many liberals, and other primitive human like organisms.

It seems that there was one mutation in the genetic material of the virus, which enabled the virus to infect humans.

This mutation coded for an alanine, instead of a threonine (different amino acids). This change made it more
difficult for certain sugars to bind to the attachment spike protein which enables better attachment with the human receptor. Apparently, those sugars got in the way of the attachment.

It is likely, that this mutation has occurred many times and until the virus infected a human, it may not have been a trait that was selected as favorable.
As we have witnessed with the emergence of new variants, it seems that the virus readily mutates.
Those mutations that are advantageous to the spread of the virus are selected for.

While it is possible, that the bat directly came in contact with the human, it is more likely, that the bat bit an animal (perhaps a pet, livestock, or other animal that comes in contact with humans) and it was passed onto humans by such an intermediate animal, perhaps from a sneeze or cough from that animal.


You can read about this new research from the following link;

I went for a few months without flying drones. The model I purchased a few years ago, uses GPS guidance with the ability to shoot high quality 4K video. My intent was to study and pass the FAA Part 107 test and be certified to fly drones commercially... as in making money legally doing aerial photography. While it's on my list, other things keep getting in the way!

Three weeks ago, I connected with friends who fly for sport in a huge public park with a section off to one side for us to enjoy model aircraft. I did 10 minutes of flying but for some unknown reason, the video I recorded had a green tint. I suspect there could be some corrosion on the connector to the camera that needs attention.

Checking YouTube to see if anyone else had the same trouble, I came across a video with a drone that uses a ducted fan design instead of the conventional propellers.
While ducted fan technology isn't new to airplanes or drones, the inventor believes his design and shape of the propulsion tubes is unique. Therefore, he has applied for a patent.

His idea came about for safety as drones can be dangerous if they strike someone. The development of large scale quadcopters (drones) used to carry people also shares the same drawback. Some of the prototype designs I've seen all have blades in locations that could be strike someone nearing the airship.

1. More so an observation. Art and beauty are not logical. To answer a question such as: Why did they put so much time, or effort, or money into doing that beautiful design like that? Is there really an answer to that? Or, is it sheer emotion.

2. If you do not believe in a spirit or soul, then why is a body lifeless after death?

I saw a story today about the long-term weightless effects on the human body. Astronauts returning after months aboard the International Space Station had swollen optic nerves, slightly flattened eyeballs that caused changes in vision. Some developed blood clots.
If you recall in science class, some of the veins in the legs have one-way valves called the venous pump. Researchers are finding blood flow while in orbit becomes irregular and fluids that are normally held down by gravity now float to the head, increasing pressure to the skull.

I guess they need to invent the gravity machine that was on the Starship Enterprise so no one goes floating around the bridge!

White guilty, self loathing member of the tribe. New evidence tends to discredit much of his linguistic babbling on syntax,---especially the vapid insistence that such complex human actions can be somehow based on one gene locus. JFC. His USA hating politics go downward from there. Aa.
