Can cancer be contagious?
Generally speaking, no it is not.
But Tasmanian devils face a unique challenge with Devil Facial Tumor Disease (DFTD)—a contagious cancer.
Why? Tasmanian devils have very low genetic diversity, especially in immune system genes. This means their immune systems can't tell the difference between their own cells and cancerous cells from another devil. The disease spreads through biting during fights or mating.
This tragic example highlights the importance of genetic diversity in resisting diseases and shows just how incredible our immune system is at keeping us safe!

Traveling at 99.999999% the speed of light, you could in principle travel to the center of the galaxy and back in about 7 years ship time. However, observers on Earth would experience a much longer time: 52,000 years. Time dilation is a concept from special relativity. ⬇️1/3

How do plants maximize their exposure to the sun? Through phototropism! Phototropism is the process of turning in response to a light source. A plant achieves this with a hormone called auxin. Once light strikes one side of a plant, auxin is released from the tip.⬇️ 1/2
