Laser-driven experiments provide insights into the formation of the universe
Researchers at the Laboratory for Laser Energetics have captured for the first time in a laboratory setting the process thought to be responsible for generating and sustaining astrophysical magnetic fields.

Earth’s inner core is much younger than we thought
Rochester researchers have gathered the first field data that show the Earth’s inner core is only about 565 million years old—relatively young compared to the age of our 4.5-billion-year-old planet.

Earth’s magnetic field fluctuations explained by new data
Using new data gathered from sites in southern Africa, researchers have extended their record of Earth’s magnetic field back thousands of years to the first millennium.

Earth’s magnetic field—reversing or fluctuating?
For the last 160 years, the Earth’s magnetic field has been weakening. In an essay shared on Newsweek, professor John Tarduno explains archaeomagnetism research, in which geophysicists team up with archaeologists to study the effects of these changes.
