The Eight Kinds of Love

There are several mentions of eight types of love purportedly discussed by the ancient Greeks, but I’m short on the actual references.

In no particular order:

  • Agape: unconditional love
  • Eros: romantic love
  • Philia: affectionate love
  • Philautia: self love
  • Storge: familiar love
  • Pragma: enduring love
  • Ludus: playful love
  • Mania: obsessive love

I had an earlier post on The Four Loves by C. S. Lewis, but now I see that he just left out half of them for some reason. Missing are Philautia, Pragma, Ludus, and Mania, which seem important, but since I haven’t read the book, I don’t know his reasons.

8 Types of Love – Which One Are You?

A Crystal Structure of the Main Protease of COVID-19

One can gain knowledge from words, but wisdom only from things.

— George Wald, Harvard biochemist and 1967 Nobel Laureate

Many images of the coronavirus SARS-CoV-2 (a.k.a. 2019/nCoV a.k.a. COVID-19) are in the media, with the colorful spiky ball motif being the most frequent. Above is a representation of one of its proteins, its main protease, which allows the virus to process the proteins created after it splices its own RNA genetic material into your cells.

The larger three lobed spiky proteins from which these types of viruses gets the name “corona” are responsible for grabbing onto and opening up the surface of (in this case) lung cells, so that this smaller protein can perform its function within the cell. In more detailed images, you may have seen it as small pairs of spheres on the viral surface.

Several different crystal structures of  various proteins of COVID-19 have been solved and released recently, including this main protease and the spiky protein peplomers. Studies of these structures will hopefully lead scientists to discover inhibitors to their functions and thus treatments and preventive measures. Go science!

Unfortunately, these results will come much too late for many of us. Science could have also helped us with the initial defense against this deadly virus, but the powers that be deigned to consider the gravity of our plight. And even today many such leaders and spokespersons are ignoring important information and spreading misinformation.
