Fiber optic sensor measures tiny magnetic fields

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...

Diamond quantum sensors measure neuron activity

A recent study by European scientists shows that highly sensitive sensors based on color centers in a diamond can be used to record electrical activity from neurons in living brain tissue. The work is published in the journal ...

Molecule that promotes muscle health when magnetised

As people age, they progressively lose muscle mass and strength, and this can lead to frailty and other age-related diseases. As the causes for the decline remain largely unknown, promoting muscle health is an area of great ...

Researchers identify genes that help trout find their way home

In the spring when water temperatures start to rise, rainbow trout that have spent several years at sea traveling hundreds of miles from home manage, without maps or GPS, to find their way back to the rivers and streams where ...
