Did you know that spilled coffee inspired a UC Berkeley engineering PhD candidate to create a breakthrough in medical testing? ☕️ Kamyar Behrouzi, now graduated, developed the rapid diagnostic test based on the “coffee-ring effect,” the pattern formed when spilled coffee dries and particles then migrate to the outer edge. The test can deliver results in as little as 12 minutes and has shown accuracy far exceeding that of existing rapid COVID-19 tests. Researchers say the method could be adapted
