No, that’s not a radioactive donut… it’s the first photo of a supermassive black hole at the centre of our galaxy, The Milky Way. Sagittarius A* is 4 million times larger than the sun and 26,000 light-years from Earth!
Coffee leaf rust (CLR), first recorded in Ceylon (now Sri Lanka) c. 1870, is one of the most notorious and important coffee diseases worldwide. Ceylon exported 100 million pounds of coffee/year and in 1889, less than 20 years later, it dropped to 5 million pounds, and production essentially stopped.
The easiest way to get better at brewing coffee is to make sure you change only one variable at a time. This is the only way to ensure that the change you made is what affected the brew. Logging brews can help you track what changes you’ve made, and their impact in the cup.
Food and drink taste different at different temperatures, as temperature effects on different compounds are not uniform. Research shows that at hot temperatures bitter and sweet tastes dominate salty and sour ones. This could be one reason why perceived acidity in coffee increases as the cup cools.
