Earth's earliest life forms developed ways to survive the harmful effects of arsenic to cope with dramatic changes in their environment, a new study suggests. The researchers found the complex life forms, called eukaryotes, stored arsenic inside...
A study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished—doubling in numbers...

Earth’s inner core is less solid than previously thought: Study reveals structural transformation

The surface of the Earth's inner core may be changing, as shown by a new study by USC scientists that detected structural changes near...

Scientists discover molten layer covering Martian core

NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints...

Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench...

Bouncing seismic waves reveal distinct layer in Earth’s inner core

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists from...

What do early Earth’s core formation and drip coffee have in common?

A new technique developed by Carnegie's Yingwei Fei and Lin Wang provides fresh insight into the process by which the materials that formed Earth's...

Earth’s inner core may have started spinning other way

Far below our feet, a giant may have started moving against us. Earth's inner core, a hot iron ball the size of Pluto, has stopped...

New ice core analysis shows sharp Greenland warming spike

A sharp spike in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees (1.5 degrees Celsius) hotter than its 20th-century average, the...

Ice core taken in Antarctica contains sample of atmosphere from five million years ago

A team of researchers affiliated with multiple institutions in the U.S. has successfully pulled an ice core from Antarctica's Ong Valley that contains samples...

The Earth moves far under our feet: A new study shows the inner core oscillates

USC scientists have found evidence that the Earth’s inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate...

Seismic waves from earthquakes reveal changes in the Earth’s outer core

In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September...

The Earth moves far under our feet: A new study shows that the inner core oscillates

USC scientists have found evidence that the Earth's inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate...

Earth’s core: Unexpected flow behavior in liquid metals

Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth’s core,...
