Which accident was reported in the news?
16. The authorities in Mexico have identified 13 of the 31 people killed in a series of explosions in the country’ s biggest fireworks market on Tuesday. The Mexico state prosecutor said some were so badly charred that neither their age nor the gender could immediately be determined.
17. The sound of burning rain forest. This is from footage captured by researchers in the Eastern Amazon. Their two-year study found that even selective logging in protected forests opened up the canopy enough to dry out the undergrowth and make it catch fire more easily. To measure the impact of human activity on the rain forest, the team counted 2,000 species of trees, insects and birds, comparing biodiversity with the amount of forest cover.
18. The growing popularity of e-cigarettes has prompted debate about their safety, their potential to help people quit tobacco smoking and the risk. They may encourage some people to take it up. The Royal College of Physicians concludes that their impact so far has been very positive. They’ ve helped many thousands of people to quit and the switch from tobacco smoking is a dramatic step towards better health.
19. The damaging effects of shift work on the body are well known. This study shows the impact on the mind as well. Three thousand people performed tests of memory and speed of thought. Those with more than ten years of shift work under their belts had the same results as those who didn’ t do shifts but were six-and-a-half years older. The good news is that when people in the study stopped shift work their brains did recover, although it took five years.
20. Ever since Mount Everest opened to commercial expeditions in the 1990s, climbers have sought to establish world records on the mountain. The youngest person to reach the summit was a 13-year-old from the United States. The oldest climber was 80. But now Nepal says it wants to limit climbers to between the ages of 18 and 75 in order to better manage the mountain, which has suffered from overcrowding. It’ s also considering banning anyone with disabilities.
