A large team of researchers in France and the UK explore whether that question—the question, not the coffee—is a good way to get people thinking about: how difficult it can be to find an effective treatment for any problem, and how easy it can be to […]
Man and woman’s yearning for perfection, in this case perfection keyed to the deployment of coffee and cow manure, is the driving force behind this new study: “In Search of the Optimal Inoculum to Substrate Ratio During Anaerobic Co-Digestion of Spent Coffee Grounds and Cow Manure,” Çağrı Akyol, Waste Management and Research, epub 2020.

“Coffee, Tea, and Mood Experiments” is a featured article in the special Coffee, and Tea issue (volume 26, number 4) of the Annals of Improbable Research. If you indulge in a cup of coffee or a cup of tea, inform yourself—in a tiny and certainly iffy way—as to what you might be doing to your […]
