NASA Is Bringing Rocks Back From Mars, But What If Those Samples Contain Alien Life? asks LAist. “NASA is planning its first-ever mission to bring dirt and rocks from Mars back to Earth — but before that momentous event happens, the space agency needs to figure out exactly how to protect our home planet from any alien microbes that might hitch a ride. This week, the agency is holding public meetings and looking for feedback on its plan to land a spacecraft carrying Martian specimens at a U.S. Air Force testing range in Utah in the early 2030s.

Scientists Use AI to Create an Enzyme That Breaks Down Plastic in a Week Instead of a Century, reports Singularity Hub. “your last toothbrush, the one you threw out a couple months ago and never thought of again, will still be slowly decomposing in a landfill in 100 years. Apply that same thought to all the plastic in your home, then all the plastic in the world, and… it’s a lot.”

How Can Quantum Mechanics Help Researchers Understand the Deep Earth? For Earth Day, learn about how science at its smallest scale is applied to the depths of our planet.  “Nature is quantum,” said Wentzcovitch, a professor at Columbia Engineering and the Lamont Doherty Earth Observatory. 

Fixing the Standard Model: The Discovery That Could Have Predicted Why the Universe Exists, reports Maxwell Moe for The Daily Galaxy. ““The Standard Model as it stands cannot possibly be right because it cannot predict why the universe exists,” said Gerald Gabrielse, the Board of Trustees Professor of Physics at Northwestern University.”

How Taipei discovered an active volcano on its doorstep, reports BBC Future. “When Taiwan’s capital discovered an active volcano on its doorstep, it found itself hastily setting up a system to monitor it for dangerous signs. This smouldering moonscape is Xiaoyoukeng, an impressive collection of steam vents in Yangmingshan National Park, an 11,000-hectare (42 sq-mile) expanse of hiking trails lying within Taipei’s city limits.

“Yellow Brick Road” Discovered In Pacific Ocean During First-Ever Exploration Of Underwater Volcanoes, reports IFLScience.” The natural brickwork was actually the result of volcanic geology which has fractured the rock in a curiously uniform way. E/V Nautilus pilots exploring the Ancient Seamounts of Liliʻuokalani Ridge as part of the Luʻuaeaahikiikekumu expedition were behind the discovery.

This Is the Most Dangerous Volcano on the Planet, reports 24/7.Despite sometimes giving out warning signs, volcanic eruptions are unpredictable. Even relatively less explosive ones can cause significant damage and fatalities, like the Nevado del Ruiz eruption in Colombia in 1985. Perhaps the most well-known deadly eruption is Mount Vesuvius in 79 A.D. It is estimated the catastrophe killed as many as 15,000 people. The volcano remains active. Currently, the most dangerous volcano on the planet is Aira in Japan.
