2 . Fast walkers may live longer than dawdlers (缓慢的人)— regardless of their weight, a new study suggests.
Researchers at Leicester University analyzed data on 474, 919 people with an average age of 52 in the UK Biobank between 2006 and 2016. They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old, and men who kept up the pace had a life expectancy of 85.2 to 86.8. Slow walkers hadn’t much encouraging prospects (前景): women had a life expectancy of 72.4, and men of 64.8 years old, if they were more leisurely in their movements. According to the paper, published last week, that ratio held true even if the fast walkers were severely overweight. It does not necessarily mean fast walkers will live longer. Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.
It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.
In 2011, the Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski, who found the same: walking speed was a reliable predictor of life expectancy.
In 2013, US researchers found walking pace was linked to lower heart disease risk and longer life expectancy. In 2018, a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.
And Tom Yates, the physical activity professor at Leicester who's behind the latest study, has been publishing findings on this connection for years.
In 2017, he analyzed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease — concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.

3 . It was a February afternoon in a Brooklyn classroom. Sixteen-year-old Taylor Engler came face to face with a cow. But it was all in her head. She was transported by a virtual reality (VR) headphone. It took the Berkeley Carroll School junior and eight other classmates to a northern New York farm. The farm was 250 miles away. For students, the technology means field trips are no longer kept within the length of a bus ride.
It's unknown how many classrooms have or will use the technology, but experts say few classrooms do or will do. Headphones that require a user's phone can cost as little as $20 or $30, but systems and software for classes run into thousands of dollars. The problem of not having good software is disappearing as more companies enter the market. But the rules for use haven't kept abreast of the development of the technology. In New York, for example, virtual reality lab experiments are not included in the state's hands-on lab time requirements.
Experts say science classes are where virtual reality holds promise for classrooms. “The biggest problem, I think, is going to be how closely it mimics the real world." That's according to David Evans, the director of the National Science Teachers Union. However, he said, “The ability to do dangerous things and to run many, many more cases in a virtual space as opposed to the real physical space stands for a huge learning chance.”
Lamb taught chemistry and he agreed. “Too often in schools, when you do experiments in labs, you mix these together, you mix those together and you get this result. And if you don't get that result, you have done something wrong. But we don't have enough resources for you to redo it, “he said. “In virtual reality, all I do is hit reset on the computer. I don't have to actually use chemicals.”
