Glacier Lost and Found High on a mountain in Norway, researchers have found a lost ski. This normally would not be big news, but this wide wooden ski is 1,300 years old. Preserved in the ice, it still has the leather straps that held it on the wearer’s foot. And it’s one of a pair. Scientists discovered the first ski back in 2014, as the ice melted due to global warming. Now more ice has melted, revealing the second ski. No one knows who wore these skis, or why they were left behind on a mountain. But the discovery shows that skis have been around for a long time, in a form very similar to the ones we use today. Melting glaciers are not a good sign for the climate,…

Too Much of a Good Thing? Some of your blood cells have a special job. They make antibodies, tiny blockers that disable invading microbes. The body makes five main types of antibodies. One, called IgE, targets parasites, such as roundworms or hookworms. It’s IgE that causes allergy trouble. Sometimes, the immune system mistakes harmless dust or cat fluff for a parasite and starts pumping out IgE. This causes cells in the nose and skin to release a chemical called histamine. Histamine signals the nose and lungs to make more mucus. And, voilà—allergies: runny or stuffy noses, sneezing, and coughing. Not Dirty Enough? So what causes the immune system to over-react? Some experts think that it might actually be that modern life is too clean. They have noticed that children who…
