AI Thread Summary
Researchers have been unable to explain the mysterious "fairy circles" found in Namibia and South Africa despite 25 years of investigation. Studies conducted by scientists from the University of Pretoria and the Polytechnic of Namibia have ruled out various potential causes, including termite activity, toxic plants, radioactive minerals, and ostrich dust baths. The circles feature barren soil within them, while the surrounding area exhibits more fertile soil, adding to the enigma. The phenomenon remains unexplained, with some humorously suggesting that fairies could be a plausible explanation. Comparisons are drawn to similar phenomena, such as the "devil's tramping ground," highlighting the uniqueness of fairy circles in Africa.

Twenty-five years of research fail to find the cause of a mysterious natural phenomenon, reports Tim Butcher at Wolwedans Camp

One of Africa's most mysterious natural phenomena still cannot be explained despite 25 years of research, scientists admitted yesterday.

Rings known as "fairy circles" that pockmark vast areas of desert in Namibia and South Africa have baffled botanists from the University of Pretoria and the Polytechnic of Namibia.

They have ruled out termite activity, poisoning from toxic indigenous plants, contamination from radioactive minerals and even ostrich dust baths as possible causes.

"At this stage I suppose we could say that fairies are as good an explanation as any," Gretel van Rooyen, professor of botany at Pretoria, told The Telegraph. [continued]

These are real enough. Anothert really interesting thing about them is though the soil in the circle is barren there is a ring of soil just putside the circle which is seemingly more fertile than the surrounding soil.

here's a slightly better article on it:

It is obviously the work of fairies.
 
Hmm, I was trying to find some pics of these things, because they sound quite similar to the devils tramping ground I've got up the street.

Here is one pic I managed to find of a fairy circle

And a pic of the tramping ground to save you the trouble

The main difference, from what I read about the fairy circles, there are many of them in africa, whereas this is the only one I know of around here.
 
They just need some fertilizer, is all.
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
