Sunspots 790

Things I have recently spotted that may be of interest to

someone else:

Christianity: National Public Radio reports that multi-racial congregations don't really bridge the gaps between the cultures of races.

Christianity Today has an article saying that white churches don't really deal with racism.

Computing: Gizmodo tells us about a single web page that lets you click on a variety of non-keyboard symbols, and then copy them into a document. I tried a few: ∛ ⊗ ↘ π ♫. This works in Word, as well as in my HTML editor.

Education: Gizmo's Freeware tells us about the online etymology dictionary.


Environment: Gizmodo reports that Morgan Stanley has begun keeping track of their investments in fossil fuel development projects.

Health: Gizmodo reports on a government study that recommends no more than one drink (whatever that means) of alcohol per day for all adults.

Politics: Leonard Pitts blames her church, her parents, and a lot of other entities, including traditional news media, for the death of Carsyn Leigh Davis, after she attended a mask-free celebration for teens at her church.

FiveThirtyEight analyzes the data, and finds that Trump has a problem with voter enthusiasm, as does Biden.

FiveThirtyEight also finds that most Republican governors are getting low polling marks for their handling of COVID-19, and most Democratic governors are getting good marks.

Heart, Mind, Soul and Strength looks back at the George Floyd story.


Science: Gizmodo reports on evidence, from preserved dung, that humans came to North America about 14,000 years ago.

Inverse reports that some deep-sea fish have extremely black materials as part of their skin.

Gizmodo reports on a material that can't be cut.

Using your DNA to explore your ancestry -- beware

I've recently read a great book entitled A Brief History of Everyone Who Ever Lived: The Human Story Retold Through Our Genes, by Adam Rutherford. It's about using DNA for anthropological purposes, such as finding the relationship between humans and Neanderthals. (You and I have Neanderthal DNA.) Rutherford says that the companies who tell people that they are 24% Cherokee, or whatever, are on a par with the horoscopes in the newspaper.

There are many reasons for this. One of them is that humans are all related. One evidence for that is  that many pieces of DNA are shared between various ethnic groups.

Another lesson, repeatedly told, is that the concept of race has no genetic basis. Again, we are all related. By this, Rutherford means that two people from different locations in Africa are likely to have less common DNA than either one of them and someone from, say, Belgium, have in common.

It's impossible to do justice to the book in this brief post. It is readable by people without strong backgrounds in science.

Note this passage from the Bible: Acts 17:26 He made from one blood every nation of men to dwell on all the surface of the earth, having determined appointed seasons, and the boundaries of their dwellings, 27 that they should seek the Lord, if perhaps they might reach out for him and find him, though he is not far from each one of us.

Thanks for reading.
