The disease, known as sea star wasting disease (SSWD), was responsible for one of the largest die-offs of marine animals in recent years.Wed, 14 Jan 2026 00:00:00 +0000https://envirobites.org/2026/01/14/scientists-finally-know-what-killed-billions-of-sea-stars/https://oncobites.blog/2026/01/07/cancer-cell-mitochondria-sneaky-agents-that-reprogram-healthy-cells-into-cancer-buddies/If people were asked to name an organelle inside the cell, the word “mitochondria” would certainly pop into most people’s heads.

While we cover ourselves inlayers of clothing and stay cozy in our homes, some animals use their fluffy feathers or fur for insulation.
