## Resource

Ancient volcanic rocks from Western Australia are forcing scientists to rewrite Earth's early history, revealing that plate tectonic-like processes may have been operating far earlier than anyone suspected. In the human body, a newly discovered lymphatic network in the eye could change everything we know about treating glaucoma and age-related macular degeneration. Meanwhile, an MIT study is upending a core assumption in neuroscience — it turns out logical reasoning and language live in completely separate parts of the brain. On the cancer front, 81 previously unknown cancer-driving genes were identified in one of the most aggressive forms of breast cancer, opening the door to new treatment targets. From medieval DNA overturning our assumptions about ancient family structures to lab-grown mini brains predicting Alzheimer's treatments, this episode is packed with discoveries that challenge what we thought we knew.
