The best way to reduce your risk of lung cancer? Don’t smoke. And if you do, quit smoking. But until now, researchers have been perplexed about why quitting smoking reduces your risk of developing lung cancer so significantly. In a bid to understand what happens to normal cells when they’re exposed to tobacco smoke, a team of researchers instead uncovered the surprising answer to this question. They found that in people who quit smoking, the body actually replenishes the airways with normal, non-cancerous cells that help protect the lungs – which in turn reduces the risk of getting lung cancer.
Of course, those who had never smoked were better off. But this latest study found that even in a person who had smoked every day for more than 40 years, ex-smokers had four times the amount of these protective cells than current smokers did. So even if your new year’s resolution has failed, it’s still not too late to quit.
Although research now tells us that dinosaurs likely sported feathers, media depictions still continue to show them sporting scales. But it turns out these selective depictions of dinosaurs isn’t any sort of new phenomenon. It harkens all the way back to the Victorian era, where scientists were not only in fierce competition to name these unknown fossils but even to design how people would think these creatures looked.
Is Nigel Farage a good or bad person? Well, the answer isn’t quite that simple – so maybe we should stop telling our children it is. As one researcher writes, we should challenge children of every age to see that it’s our actions that can be defined as “good” or “bad” – not the person themselves.
