🔬 Scientists Just Discovered Earth Has 3x More Species Than We Thought — And That's Just the Start

from 🎙️ Science News Daily | Peer Review'd · host Peer Review'd

A landmark analysis of over 300 studies suggests that for every known vertebrate species, two additional 'cryptic' species may be hiding in plain sight — potentially tripling our species count overnight. Researchers have also traced the ancient plague bacterium Yersinia pestis to a 4,000-year-old sheep in the Ural Mountains, offering the first clue about how the deadly pathogen spread long before the Black Death. On Mars, scientists may have identified a brand-new mineral in the planet's massive canyon system, hinting at geothermal activity that could rewrite the Red Planet's geological history. Back on Earth, a newly discovered molecular switch may hold the key to stopping breast cancer from spreading, while a five-day brain stimulation protocol is showing results that rival six weeks of standard depression treatment.Subscribe to Peer Review'd Newsletter: https://peerreviewd.com/Love Science?
