Scientists might know why astronauts develop health problems in space:
People are more likely to develop health issues with extended time in space, such as cardiovascular and sleep disruptions. But why? Scientists might have an idea. They've published research indicating that mitochondria, the energy-producing "powerhouses" of cells, may play a key role. Mice with eye and liver problems in studies often had mitochondrial dysfunctions, while NASA astronaut Scott Kelly (above) might have faced immune system changes aboard the International Space Station in 2015 as a result of mitochondrial problems.
Bodily fluid samples from many other astronauts also supported claims that mitochondrial activity changed while in space.
The potential breakthrough came in part thanks to NASA's open-source GeneLab platform. The tool aggregates large volumes of space biology data from around the world, including cell info as well as DNA, RNA and proteins.

In one article it's the folding of proteins subject to all sorts of subtle factors. And the next article wonders why removing gravity causes mysterious health problems.

Interesting point, but I bet that the protein folding people didn't take gravity force into account. Interatomic forces are much stronger than gravity, so it is reasonable to treat gravity forces as negligible.

MUCH stronger. And from a cell's perspective gravity doesn't point in a consistent direction - every time you move your hand, or lie down to sleep, you completely change the direction of gravity. If it played a significant role in protein folding there would likely be massive problems cropping up on a regular basis.

First they nuked their own earth with all the nuclear tests, then they nuked Jupiter with the Galileo probe, and latest was Saturn with Cassini.
How would earthlings feel if beings from another planet crashed a device with a plutonium core into their planet? One that implodes to cause a nuclear reaction upon contact with the atmosphere.

Right, because we've made it to actual alien worlds or even had the slightest hint of actual signs of life. Really not sure where you're going with this, other than crazy.
