Reply to comment by Gari_305 in Rolls-Royce go-ahead to build a nuclear reactor on Moon - Scientists and engineers are working on the micro-reactor programme that will help humans to live and work on Earth's natural satellite by Gari_305

>> £2.9 million of new funding for the project which will deliver an initial demonstration of a UK lunar modular nuclear reactor

That seems unlikely unless Rolls Royce is putting a lot of funding on their own.

In simulated reproductive tracts of animals like cattle and humans, the behavior increases the chances that groups of cooperative bovine sperm will outpace meandering loners as they race to fertilize a female egg cell, physicists report. by MistWeaver80

>> drafting

That would actually make sense. I wonder how much resistance there is to movement compared to air or water....
