  • Oddly, space is cold but spaceships tend to get too hot. Engines/electroncs/people give off heat inside the ship which gets trapped. You move heat by conduction, convection, or radiation, but because outside is a vacuum you cant disapate heat with the first 2 and are limited to the least effective radiation so the heat builds up








  • It’s literally in the paper! "The nomenclature varies with the diameter of the fibers (and region), including ∼2 mm spaghetti (small string), ∼1.75 mm vermicellini (little worms), and ∼900 μm capellini (little hairs). The narrowest diameter mass-produced pasta is ∼800 μm capelli d’angello (angel hair), although thinner pasta lunga is produced by hand exclusively in the town of Nuoro, Sardinia: su filindeu (threads of God), which is estimated to have half the diameter of capelli d’angello and is, to the authors’ knowledge, the thinnest pasta created by hand to date "



  • The energy for lab grown meat has to come from somewhere - thermodynamics is always king. You can provide it via sugars/carbohydrates which the cells can motabolise, but you’ve got to put energy into making the sugar/carbs which is easiest by just growing some sugarcane/potatoes/etc. There’s more steps for meat vs plant and it’s very unlikely you can make 100 calories of lab meat with lower total system energy input than 100 calories of plant matter. (N.B., I’m a chemist, not a astronomical biologist, so if an expert refutes me and my assumptions, Place more trust in them)
