A scientific fact/tidbit you recently learned that you thought was interesting

Telomeres lengthen in microgravity, then contract to shorter than their usual length when returned to a 1g environment.

Well that doesn't sound good for manned space exploration.

Maybe it starts miniscule (fingers crossed)... but it's cumulative. 😡
 
Black mould thriving at radiation in Tchernobyl:

The mysterious black fungus from Chernobyl that may eat radiation

It appears that melanin can protect organisms from radiation, and this black mould is even attracted to radiation, and is now growing inside the reactor rooms, a behaviour termed 'radiotropism'.

Along with the apparently radiotropic fungi, Zhdanova's surveys found 36 other species of ordinary, but distantly related, fungi growing around Chernobyl. Over the next two decades, her pioneering work on the radiotropic fungi she identified would reach far outside of Ukraine. It would add to knowledge of a potentially new foundation of life on Earth – one that thrives on radiation rather than sunlight. And it would lead scientists at Nasa to consider surrounding their astronauts in walls of fungi for a durable form of life support.
There is also speculation about fungi being able to gain energy from radiation:
In 2007, Ekaterina Dadachova, a nuclear scientist at the Albert Einstein College of Medicine in New York, added to Zhdanova's work on Chernobyl's fungi, revealing that their growth wasn't just directional (radiotropic) but actually increased in the presence of radiation. Melanised fungi, just like those inside Chernobyl's reactor, grew 10% faster in the presence of radioactive Caesium compared to the same fungi cultured without radiation, she found. Dadachova and her team also found that the melanised fungi that were irradiated appeared to be using the energy to help drive its metabolism. In other words, they were using it to grow.
All of this stuff is not very recent, and I apologise if it has already been brought here, but I find it interesting enough to repeat!

I doubt if manned space exploration is ever going to be possible beyond maybe a short-term manned expedition to Mars, and even that's on the edge.

Badly written or typo? "...that thrives on radiation rather than sunlight..."
