Have you ever wondered why everyone’s nose is a different shape? Researchers have come up
with a possible explanation for this. A study says the Earth’s climate could have something to do with the shape of our nose. The study found that people who have wider noses usually live in warmer, wetter areas. People with narrower noses are more commonly found in colder and drier climates. The nose plays an important function in making the air reach our lungs in a warm condition. The width of the nostrils and length of the nose help to make sure this happens. Researchers said the nose is a little like a temperature controller.

Scientists may have found one answer to the problem of water shortages. It is a new material
that collects water from the air. They got their idea from a small beetle that lives in the desert in Africa. The deserts in Namibia are very dry, but the desert beetle is an expert at surviving in hot and dry conditions. Its skin is covered with small holes that collect tiny water drops from the air. The water is enough to keep the beetle alive. Scientists studied the shape and material of the beetle’s skin. They want to use what they found out about the beetle to make their own materials that can collect water from the air. This will help people who live in very dry areas. The scientists believe this new technology could help in many areas of our life.
