Slight shifts in magnetic field preceded California earthquakes

Researchers studying intermediate to large earthquakes in California have discovered detectable changes in the local magnetic field that occur 2–3 days before an earthquake. In a study now published in Journal of Geophysical ...

The first look at how rabies affects vampire bat social behavior

Vampire bats infected with the rabies virus aren't likely to act stereotypically "rabid," according to a new study—instead, infected male bats tended to withdraw socially, scaling back on the common habit of grooming each ...

The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. The pair are the first recorded events to occur on the planet's far ...

The seismic zone worrying quake-hit Mexico

A 7.1-magnitude earthquake that struck southern Mexico this week originated near a section of a fault that experts worry has been building up tension for more than a century.

The 27.5-million-year cycle of geological activity

Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study published in the journal Geoscience Frontiers.
