4 . Why Are You Still Coughing?
Have you caught a cold recently — but can’t get rid of the cough? You’re not alone. The symptom can stick around for weeks after our bodies have cleared a virus. Michael Shiloh, a physician specializing in infectious disease research at UT Southwestern Medical Center, says coughing patients often report that they were sick as many as eight weeks prior to seeing him. He says, “
The United States saw a sharp rise in cases of influenza in late 2023 that’s dragged on into 2024. And though positive tests for the illness have leveled off or decreased countrywide over the past weeks, the number of people seeking healthcare for respiratory (呼吸的) diseases is still elevated across much of the U.S.
Coughing is an important reaction that protects the airway from dangers like water or bits of mis-swallowed food, says doctor and researcher Lorcan McGarvey of Queen’s University Belfast.
While it may seem obvious that coughing is meant to clear our throats, it’s also possible that viruses cause the reaction to help themselves spread.
“We don’t know,” says electrophysiologist Thomas Taylor-Clark of the University of South Florida. “But what we can say is that we do know some things, one being that viruses cause infection.”

How Long Is a Second?
The length of a second depends on how you’re measuring it. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute — so surely a second is 1/86400, of a day, right? Well, it turns out that
“The second was

By around 1940, quartz crystal clocks (石英钟) had become the new gold standard. However, problems arose, and this was where atomic clocks came in. “Atoms exist only in particular energy states and can only change from one state to another by
In fact, scientists are discussing whether it’s time to redefine the second again. But while several important questions still need to be answered before this
6 . At first the question was how quickly people would get back to the office. Then it was whether they would ever return. The last three years has introduced in a major change in white-collar working patterns. The office is not dead but many professionals have settled into a hybrid (混合的) arrangement of some office days and some remote days.
Hybrid working has much to recommend: flexibility for employees, periods of concentration at home, bursts of cooperation in the office. A new paper from Harvard Business School describes an experiment in which workers at BRAC, a non-profit organisation in Britain, were randomly assigned to three groups, each spending different amounts of time working from home. The intermediate (中等的) group, who spent between 23% and 40% of their time in the office, performed best on various performance measures.
But a shift on this large scale is bound to raise tricky issues. In workplaces that have moved to hybrid work, there are still plenty of open questions. One is how to handle the impact of less time in the office for new joiners and younger workers. Research by Emma Harrington of the University of Iowa shows that software engineers receive more feedback on their code when the team sits next to each other in the office, especially new engineers. According to Nicholas Bloom of Stanford University, making new employees spend more time in the office can be a good way of integrating them into company culture and improving their competence. And these younger employees were most likely to quit when everyone was forced to go remote.
A second question concerns how strictly to enforce attendance on days when teams are meant to be in the office. An agreement holds that there should be agreed “anchor days” on which all the people come to work in the office; since the idea is to spend time together, as many people as possible should be there. But one person on the team might have moved somewhere else; someone else might have asked to stay home to let the repairer in. In practice, therefore, hybrid working still often means a mixture of people on screen and people in the office.
Other questions exist. How to define performance measures so managers do not spend time worrying about lazy workers at home? Do you require company-wide anchor days or team-level ones? The era of hybrid working is only just beginning, so it will take time for answers to emerge. But if there is a message from this first full year of hybrid working, it is that flexibility does not mean a free-for-all.
