The nice bright white glossy paper we have uses a high clay content to give the paper its qualities. Kaolin is the clay, it is named after the mountain in China where it was mined from in the early days.

And the Kaolin used to be mixed with a plant derivative pectin to make an anti-diarrhea medicine, Kaopectate. The types of clay were switched, then removed completely. The current formula includes bismuth subsalicate, like Pepto Bismol.
 
(Speaking of paper) The light reflected from the black ink of a newspaper (remember newspapers?) in full sunlight is more than the light reflected from the unprinted areas indoors. I would not be surprised to learn that this is also true of better quality paper.
 
I actually read a newspaper, honestly I find it clumsy the pages are so big that they are constantly falling over and you have to shake it back into place.
busses (and trains..) used to be filled with people reading papers.. everyone had a knack of folding it just right to make it / them manageable..

Beavers (as well as some other animals) eat their poop.

Our dog occasionally chews on a dried turd she finds. She also seems to want to roll in any non-canine poop she finds. Like cat, which is awful. We got some gardening soil this afternoon to plant veggie beds. Let her out in the back yard where we were working and she started rolling on one of the bags; it smelled like manure is a significant component of the mix.

Random nerdy fact:

Dogs roll in poop in order to disguise their scent from prey. It's like hunters spraying fox urine on their boots.
 
Technically, it can be said that the lightest element is not hydrogen. It's positronium (Ps), with one electron and one positron. It was postulated back in the 1940s. Unlike the other elements, in Ps the electron and positron circle about their center of mass.

Ps-H and Ps-Ps have been made. Such materials would make rather interesting propellants if it weren't for the fact that the lifetime of Ps is about 0.1 ns.:shocked:

There are analogues of Ps, e.g., protonium (proton and antiproton).
