Stuff below the fold

There is an Orthodox church on an island at the tip of Antarctica
photosource en.wikipedia Erected to serve the nearby Russian research station.

------------------------------------------
 Other chapels on the continent of Antarctica LINK
some Church is multi-confessional, so that is the case of the Chapel of the snow at US McMurdo Base, other are Ortodox as the St. Kliment at the Bulgarian Base or the Russian Ortodox Trinity Church at Bellinghausen Base.

 FYI: There is ice on Mercury.

DRB has a photo essay on weird water towers.

Perhaps inspired by the coffee pot design, this coffee cup water tower can be seen in Stanton, Iowa (left image ). On the right is a very nice way to welcome you to Ashley, Indiana - with a big smile...
some of the older watertowers look like defensive towers or castles:

The Drobeta-Turnu Severin Water Tower in Romania looks distinctly medieval but was built in the early twentieth century (left image below). The red brick water tower in Malbork, Poland (right image) dates from 1905:

and scientists answering the really important question of the day: Here we eat Durian, the fruit that "Smells like hell but tastes like heaven".
However, they are  not loved by many:



Why does Durian smell so bad?

An aroma extract dilution analysis applied on the volatile fraction isolated from Thai durian by solvent extraction and solvent-assisted flavor evaporation resulted in 44 odor-active compounds in the flavor dilution (FD) factor range of 1–16384, 41 of which could be identified and 24 that had not been reported in durian before. High FD factors were found for ethyl (2S)-2-methylbutanoate (fruity; FD 16384), ethyl cinnamate (honey; FD 4096), and 1-(ethylsulfanyl)ethanethiol (roasted onion; FD 1024), followed by 1-(ethyldisulfanyl)-1-(ethylsulfanyl)ethane (sulfury, onion), 2(5)-ethyl-4-hydroxy-5(2)-methylfuran-3(2H)-one (caramel), 3-hydroxy-4,5-dimethylfuran-2(5H)-one (soup seasoning), ethyl 2-methylpropanoate (fruity), ethyl butanoate (fruity), 3-methylbut-2-ene-1-thiol (skunky), ethane-1,1-dithiol (sulfury, durian), 1-(methylsulfanyl)ethanethiol (roasted onion), 1-(ethylsulfanyl)propane-1-thiol (roasted onion), and 4-hydroxy-2,5-dimethylfuran-3(2H)-one (caramel). Among the highly volatile compounds screened by static headspace gas chromatography–olfactometry, hydrogen sulfide (rotten egg), acetaldehyde (fresh, fruity), methanethiol (rotten, cabbage), ethanethiol (rotten, onion), and propane-1-thiol (rotten, durian) were found as additional potent odor-active compounds. Fourteen of the 41 characterized durian odorants showed an alkane-1,1-dithiol, 1-(alkylsulfanyl)alkane-1-thiol, or 1,1-bis(alkylsulfanyl)alkane structure derived from acetaldehyde, propanal, hydrogen sulfide, and alkane-1-thiols. Among these, 1-(propylsulfanyl)ethanethiol, 1-{[1-(methylsulfanyl)ethyl]sulfanyl}ethanethiol, and 1-{[1-(ethylsulfanyl)ethyl]sulfanyl}ethanethiol were reported for the first time in a natural product.

Hello. I saw you post regarding Drobeta-Turnu Severin Water Tower and I want to thank you for posting about a very importnat monument of my city.
The tower was a gift from the first romanian king - Carol I.

Have a nice day!
