Although it makes up everything we see and touch around us, ordinary matter only accounts for about 15 percent of the mass of the universe. The other 85 percent is believed to be dark matter, a ...

Physicists propose a dark matter detector that would use superfluid helium to explore mass ranges for dark matter particles thousands of times smaller than current large-scale experiments. Physicists ...

Scientists are building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans. Sandia National Laboratories scientists are ...

ALTHOUGH the most common high-sensitivity detectors now in use for gas chromatography consist of either the flame 1 or the argon ionization device 2, such instruments cannot be used for the analysis ...
