Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...

'ZDNET Recommends': What exactly does it mean? ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources ...

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 ...

Scientists have discovered a new reason for turtles to dance for joy: Loggerhead sea turtles seem able to discern and remember magnetic field signatures, which could help them find food.

Researchers recently used this distinctive behavior to test whether loggerheads could identify the specific magnetic field signatures of places where they had eaten in the past. The results ...

The S Pen on the Galaxy S25 Ultra could display magnetic interference issues just like its predecessor. A system warning confirms that magnets can disrupt S Pen signals, affecting writing accuracy ...
