15 The secret of how to make a perfect cup of tea has finally been discovered by put the milk in first. The finding that a cup of tea tastes better English scientists if the tea is poured into the milk appeared to have settled an argument that has been of major concern to this nation of tea drinkers. 52 It all began after Dr. *Andrew Stapley, a chemical engineer at *Loughborough University, revealed 3) the recipe for a perfect cup of tea. He said the keys to producing the perfect cup were using *soft water, warming the pot and allowing the tea to stand for three minutes. As to the difficult issue of whether the milk or tea should be poured in first, Dr. Stapley said science proved it must be the former. The reason is that 10 when milk is exposed to high temperatures, such as being poured into a cup of very hot tea, it loses its fresh taste. 3 However, only a few hours after Dr. Stapley announced his findings to the world, a noisy debate started within the scientific community. Dr. Julia King, head of the *Institute of Physics, said the secret was to keep the water temperature at 98°C. Putting the milk in first was only a social custom that "has nothing to do with taste," she said. "In the past, only the rich could afford high quality *china cups which could withstand the hot tea being poured in directly. In contrast, those of us with cheap china had to put the milk in first to prevent our cups from cracking." ウ 262 words)

In a study published in the July 11, 2016, Current Biology, researchers found that exercise after learning may improve your memory of the new information, but only if done in a specific time window *2. (In the study, 72 participants learned 90 picture-location associations mentally linking an image with new information in order to improve recall over a 40-minute period. They were then randomly assigned to one of (1) three groups: one group exercised immediately, the second exercised four hours later, and the third did not exercise. The exercise routine consisted of 35 minutes of interval 10/training on a fitness bike at an intensity of up to 80% of maximum heart rate. After 48 hours, the participants' memory was tested while their brains were scanned*4 via MRI*5. Those who exercised four hours after the learning session retained*6 information better than the other two groups. The MRI also showed the hippocampus, the brain region involved with learning and memory, - that (2) 15 was more active when information was recalled correctly. Newly learned information turns into long-term knowledge through a process that requires certain brain chemicals that are released during exercise, but more research is needed to understand (3) this phenomenon. (4) It is also not clear why four hours was more beneficial, or if another time frame might produce a similar 20 effect.
