But new techniques in electroencephalography may soon make it possible for a totally disabled person to communicate by directly controlling the faint electromagnetic signals emitted by his or her brain.

All these lines of evidence suggest that galaxies, galaxy clusters, and the universe as a whole contain far more matter than that which is observable via electromagnetic signals.
43.
Because the outward traveling gamma pulse is propagating at the speed of light, the synchrotron radiation of the Compton electrons adds coherently, leading to a radiated electromagnetic signal.
44.
Atmospheric sources of noise are the most ubiquitous, and include electromagnetic signals prompted by cosmic microwave background radiation, or more localized radio wave noise from nearby electronic devices.
45.
Russia and the United Kingdom agreed to jointly deploy two satellites in 2015 that will measure electromagnetic signals that are released from the earth's crust prior to earthquakes.
46.
Unfortunately, the truth soon became apparent : the emitted electromagnetic signal causes paranoia and hallucinations in the living, as well as the reanimation and mutation of dead tissue.
47.
If there is no response to the electromagnetic signals, the system determines that no child seat is in use and the air bag is set for deployment in an accident.
48.
For the second time, Antony Fraser-Smith has picked up a sharp electromagnetic signal a month before a California earthquake, fueling hope that some quakes may be predictable.
49.
But, he said Dec . 11, the tenfold increase in the ultralow-frequency magnetic field signal he detected underground makes electromagnetic signals a fertile area for additional research.
50.
According to Baum, even if an extraterrestrial civilization were to communicate using electromagnetic signals alone, it could send humanity information with which humans themselves could create lethal biological weapons.
