Study devises novel process to purify exosomes from cow’s milk

Cells produce exosomes, the nano-sized biological capsules, to protect and courier delicate molecules across the body. The capsules are hard enough to resist enzymatic breakdown and acidic and temperature fluctuations in the bloodstream and gut, which makes them a major candidate for drug delivery.

Researchers report several compounds responsible for coffee’s distinctive mouthfeel

Coffee drinkers intuitively recognize the pleasure of swallowing a smooth, rich brew versus a watery one. Aside from added cream or sugar, the coffee itself contributes to this sensation -; referred to as body or mouthfeel -; but the specific compounds are not well defined.
