(Phys.org)—Biopharmaceutical macromolecules are often functionalized with polyethylene glycol (PEG), an inert chain of -(CH2CH2O)- repeating units. PEG can help make a biomolecule more soluble in water, or increase its ...
Our world is full of patterns, from the twist of a DNA molecule to the spiral of the Milky Way. New research from Carnegie Mellon chemists has revealed that tiny, synthetic gold nanoparticles exhibit some of nature's most ...

Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today's smart phones process more data, but they still weren't built for being shoved into back pockets.
