A friend of my mom pleaded with Che for the life of his son, who had been in the military, captured by the Communists, and remained in prison after they won.

Che put his hand on the man's shoulder and reassured him that his son would be safe.

Che then had the son executed.

Revolutionary Che Guevara was executed on this day in 1967.

I found the Monet paintings to have low pixellation, so I had Chatgpt improve them.

We also uncover evidence of past hybridization and find that human-driven habitat fragmentation is now causing isolation and genetic drift, highlighting the urgent need for conservation:

📣 Check out this new paper: a huge effort for the largest terrestrial animal! 🐘🌍🧬
Using 232 high-depth genomes, we can now explore the evolutionary history (and possible future) of elephants in unprecedented detail.

Climate change is occurring due to greenhouse gas emissions.

But @Nature should be embarrassed for publishing nonsense.

New research from Al Roca and Yasuko Ishida reveals that nearly half of Oregon’s elk carry a genetic variant that may help them resist chronic wasting disease, which can help slow down the spread of the disease in the state ➡️https://t.co/dUxppb95tA
