So /sci/, why is it so damn easy to design nuclear weapons? Like seriously, 14 year old me understood critical mas and gun type fission weapons pretty well. Are world governments really that relaxed about it because the manufacturing is so complicated? Or am I a fucking idiot for not realizing how complicated sliding one bit of u-235 on to another one really fast, to cause a 16 kiloton explosion, really is?

http://www.nature.com/nm/journal/v10/n2/full/nm985.html How does trehalose show positive effects here? I thought disaccharides in general have very poor oral bioavailability and blood-brain barrier penetration. Don't mice also lack a homolog for the trehalose transporters? Pls explain /sci/, I don't wanna ask my prof and sound like a dumbass.

Not sure if crazy or... well, crazy. They're going to have a robot climb more than five miles in the sky to test their technology. Best of all, it's being caught on camera: https://www.kickstarter.com/projects/shootthemoon/shoot-the-moon-a-documentary-feature-film/ At worst, I'll be able to sit back, eat some popcorn and watch the fireworks as their robot comes crashing down.

Hey /sci/. I just started undergrad research at my uni and I need a little help finding some information. My professor wants me to find some physical identifiers for liquid crystal phase transitions, and i'm having trouble finding any. I can watch the transition videos on youtube and stuff, but I have no clue what's going on. Pic kinda related I guess
