Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

An extra stage has been identified for the first time that helps explain why ice can have a liquid layer at the surface even ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...

This is the last entry — at least for this year — in my series on batteries. Batteries are the missing link to total off-grid ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers ...

Researchers discover that embedding iridium atoms inside catalyst crystals instead of on the surface dramatically improves ...

Reports of a towering shadow surrounded by rainbow rings have surfaced for centuries across mountain regions worldwide. The ...

Explore how nanotechnology acts as the 'Convergence Engine' for AI materials discovery, CRISPR gene therapy delivery, and ...
