A fundamental goal of basic biology is understanding how diverse cell types work in concert to form tissues, organs, and organ systems. While recent efforts to catalogue the different cell types in every tissue in human bodies are a step in the right direction, they address only one piece of the puzzle. The big mystery …
For centuries, it has been believed that apart from the position of the planets, even stars have an impact on humans. Now, a recent study by scientists has found that apart from the Sun, the other stars can also have a great impact on Earth and may even change its orbit. They claim that the …
