A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

Typesetting physical quantities requires care to ensure that the combined mathematical meaning of the number-unit combination is clear. In particular, the SI units system lays down a consistent set of ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar radiation — and helps guide the migrations of many animals. Loggerhead ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European ...

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favorite spots, scientists said Wednesday. Some animals that migrate ...

It’s a simple magnetic ring attached to a non-magnetic finger ring that doubles as a kickstand. But what if both rings were magnetic? What if both of them were the same size? What if each of ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells ...

Good morning, I’m Dan Gartland. This will be the last SI:AM for a little while, since I’ll be out of the country until Feb. 24. It’s such a shame I won’t be able to write a daily sports ...
