Deep Earthquake Aftermath: Why Deeper Crust Changes Persist Long After Shaking
New Insights into Post-Seismic Deformation When an earthquake rattles the ground, it often leaves a visible legacy of cracked roads and toppled buildings. But beneath the surface, the story continues. Geologists are increasingly focused on post-seismic deformation—the way the Earth’s crust gradually adjusts to the sudden redistribution of stress after a quake. Recent work from…

Deeper Crust Takes Longer to Heal After an Earthquake, MIT Study Finds
Overview: What post-seismic deformation reveals about the crust Earthquakes are not a one-and-done event. The initial shaking is followed by a period of post-seismic deformation, a time when the surrounding rocks adjust to the sudden changes in stress caused by fault rupture. In this phase, areas that didn’t fracture still experience stress shifts and adapt,…

First Evidence of Proto Earth: 4.5-Billion-Year-Old Materials Unearthed by Geologists
New Clues from the Deep Past: Proto Earth Resurfaces In a groundbreaking study published in Nature Geoscience, researchers from MIT and collaborating institutions report the most compelling evidence yet of proto Earth materials. These remnants, dating back roughly 4.5 billion years, predate the giant collision that shaped the Earth as we know it today. The…

Proto Earth Revealed: First Evidence of a 4.5-Billion-Year-Old Building Block
A Glimpse into Earth’s Distant Origins Scientists at MIT and collaborating institutions have uncovered what may be the first direct evidence of proto Earth—the primordial material that predated the giant impact that transformed our planet. Reported in Nature Geosciences, these findings hinge on a subtle imbalance in potassium isotopes detected in some of the oldest…

MIT Advances Optical Atomic Clocks by Halving Quantum Noise with Global Phase Spectroscopy
Reaching New Heights in Timekeeping Every moment you rely on precise timing—whether checking a phone, making a digital payment, or navigating via GPS—you benefit from the extraordinary accuracy of atomic clocks. Today’s standard clocks track cesium atoms, ticking at about 10 billion times per second. But scientists are pushing toward optical atomic clocks that work…

Optical Atomic Clocks: Boosting Precision by Reducing Quantum Noise
Introduction: The Quest for Ever-Precise Time From checking the time on a smartphone to guiding navigation and delivering online payments, modern life depends on the extraordinary precision of atomic clocks. Traditional clocks rely on cesium atoms ticking billions of times per second, tracked by lasers at microwave frequencies. The next leap in timekeeping aims to…

Chemical Patterns in Metals: New Physics for Manufacturing
Introduction: A Hidden Order in Metal Processing For decades, scientists believed that the chaotic mixing during metal processing largely erases any subtle chemical patterns. New research from MIT challenges this view, showing that metallic atoms retain non-random arrangements even after conventional manufacturing. These archive-like patterns influence a metal’s mechanical strength, durability, heat capacity, and radiation…

New Physics in Metals Manufacturing: Hidden Chemical Patterns
Uncovering a Hidden Layer in Metal Manufacturing For decades, scientists believed that subtle chemical patterns in metal alloys were either too small to matter or easily erased during processing. A collaboration at MIT has upended that assumption by showing that these patterns persist in conventionally manufactured metals and can influence a wide range of material…

Red Fluorescent Dyes Based on Borenium Ions Could Improve Clearer Biomedical Imaging
MIT Develops Stable Red-Emitting Dyes for Better Biomedical Imaging Scientists at MIT have designed a new class of fluorescent molecules based on positively charged boron atoms, known as borenium cations, that glow in the red to near-infrared range. By stabilizing these ions with specially chosen ligands, the team has created materials that emit bright light…
