It's one thing to be healthy in space - but what if an astronaut falls ill? What are the challenges in medical care and even surgery? One study decided to look at exactly that: https://onlinelibrary.wiley.com/doi/full/10.1002/bjs.10908

The above article is also valuable for exploring general effects of zero gravity on the human body and worth a look for that alone.

Impatient planets don't wait for stars

When does planetary formation begin? Apparently well before the parent star is fully formed: Planet formation starts before star reaches maturity

"The results indicate that planets already start forming while the star is still developing. The star is only half to three-quarters of its final mass. This is new."
