Bringing magnetic resonance to fertility treatment

EPFL spin-off Annaida is developing a magnetic resonance system that can detect the chemistry inside the tiniest living organisms. The technology's initial application will be in the field of fertility treatment, where it ...

A gentler technique for artificial respiration

In intensive care wards, artificial respiration is often used as a last resort to save a patient's life. Unfortunately, however, it brings with it the risk of acute or chronic lung damage, particularly if the ventilator is ...

New thermal ablation method for adenoma shows promise

Researchers from the USA (Kansas State University) and the Republic of Ireland (the National University of Ireland Galway) have completed a successful initial test of a new microwave thermal ablation technique, which could ...

The nocebo effect: Media reports may trigger symptoms of a disease

Media reports about substances that are supposedly hazardous to health may cause suggestible people to develop symptoms of a disease even though there is no objective reason for doing so. This is the conclusion of a study ...

Neuroprosthesis gives rats the ability to 'touch' infrared light

Researchers have given rats the ability to "touch" infrared light, normally invisible to them, by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes ...

MRI scanners affect concentration and visuospatial awareness

Standard head movements made while exposed to one of the three electromagnetic fields produced by a heavy duty MRI scanner seem to temporarily lower concentration and visuospatial awareness, shows an experimental study published ...

Electromagnetic radiation

Electromagnetic radiation (sometimes abbreviated EMR) is a ubiquitous phenomenon that takes the form of self-propagating waves in a vacuum or in matter. It consists of electric and magnetic field components which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. Electromagnetic radiation is classified into several types according to the frequency of its wave; these types include (in order of increasing frequency and decreasing wavelength): radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. A small and somewhat variable window of frequencies is sensed by the eyes of various organisms; this is what we call the visible spectrum, or light.

EM radiation carries energy and momentum that may be imparted to matter with which it interacts.
