Water for Moonbases?
Finding frozen water in some parts of the moon has implications for space exploration including the possible supply of water and oxygen for a manned moonbase.
"Finding useful quantities of frozen water on the moon would have implications for space exploration. Not only would it provide water and oxygen for a manned moonbase, it would also give astronauts a source of hydrogen to use in rocket fuel. Extracting gases from water becomes cost-effective when the amount of ice in lunar soil rises above 1%... At the levels found, astronauts would have to process one cubic metre of lunar soil to get 100 millitres of water, or less than a fifth of a pint." "What we found was...an oasis in an otherwise desert on the moon..."
We're more dependent on them than we realize.

While short-term results are positive, there is mounting evidence against staying in ketosis for too long.
- Recent studies showed volunteers lost equal or more weight on high-carb, calorie-restricted diets than low-carb, calorie restricted diets.
- There might be positive benefits to short-term usage of a ketogenic diet.
- One dietician warns that the ketogenic diet could put diabetics at risk for diabetic ketoacidosis.
