- 英譯漢 Think this way, it’s your inability to resist cheesecake that’s making it tough to fit into your skinny jeans? Well, a new study shows your bacteria may share some of the blame. Because the new study in mice reveals that the response of intestinal microbes to a high-fat diet ends up triggering the release of a hormone that makes mammals feel hungry, causing them to eat even more. The finding is served up in the journal Nature. Previous work has shown that the types of bacteria in the gut in diabetic or obese individuals are different from the bacteria in healthy people. But does this bacterial makeup contribute to these disorders? Or is it just a side effect? To unravel this mystery, researchers put mice on a high-fat diet. As a result, the animals experienced a buildup of a chemical called acetate (醋酸鹽), particularly in the large intestine(腸).

- 9 【英譯漢】 Think about driving a route that’s very familiar. It could be your commute to work, a trip into town or the way home. Whichever it is, you know every twist and turn like the back of your hand. On these sorts of trips it’s easy to zone out from the actual driving and pay little attention to the passing scenery. The consequence is that you perceive that the trip has taken less time than it actually has. This is the well-traveled road effect: people tend to underestimate the time it takes to travel a familiar route. The effect is caused by the way we allocate our attention. When we travel down a well-known route, because we don’t have to concentrate much, time seems to flow more quickly. And afterwards, when we come to think back on it, we can’t remember the journey well because we didn’t pay much attention to it. So we assume it was shorter.
