3 cool science stories from today

It turns out today was chock-full of interesting science stories. I thought all of these were really good.

1. Emergent Gravity - good story about "emergent gravity" and a paper that's bringing the discussion that gravity may not be fundamental but is instead just an emergent property of a complex system. I've seen several stories about this recently but this provides a good background for the clue-less like myself.

2. The Bacteria in us all. I am always hesitant to take medicines, especially antibiotics, because I've tended to view my "system" as myself and a whole bunch of beneficial microbes living in me in sortof a symbiosis - and antibiotics for me seem kindof like bombs that kill everything in your system good or bad. Here's a story that talks about how little doctors or science knows about the biospheres inside of us, and how promoting the correct type of bacteria in us may be what's needed in the first place.

3. Interesting finding about preventing brain damage during stroke. I found this a highly non-intuitive finding - brain damage in a stroke can be minimized/prevented by stimulating the brain area impacted - at least in a rat. Flicking a whisker makes all the difference, but there are obvious things to try in people.
