The Florida Current May Be Slowing Down, but Not by Much
A needed correction to a widely used data set reduced scientists’ estimates of how ocean circulation has weakened.
The Unexpected Role of Magnetic Microbes in Deep-Sea Mining
A new study highlights the co-occurrence of magnetic bacteria and polymetallic nodules and may offer insights into how the mineral-rich nodules form on the ocean floor.
Scientists Captured the First Glimpse of a Rare Polar Aurora
After a decade-long search, scientists captured a type of elusive aurora on camera.
Coronal Mass Ejection Gives Earth’s Magnetosphere Rare “Wings”
A massive disturbance in the solar wind caused Earth’s magnetosphere to fly without its usual tail.
Microbes Likely Form Magnetite in the South China Sea
Researchers sampled sediment cores and found that where magnetite was abundant, methane-producing bacteria were as well.
Open-Source MAGPRIME Supports Space Magnetism in the Heliosphere
MAGPRIME is a library of magnetic interference removal algorithms, including benchmarks, that can aid in the design of spacecraft by providing simulations to determine optimal magnetometer placement.
Studying the Mystery of Uranus’s Curiously Weak Radiation Belts
The belts may not be weak at all—instead, they may be simply changing speed thanks to the planet’s asymmetric magnetic field.
