Teams of physicists worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, absorb, or reflect light. Due to its lack of interactions with electromagnetic forces, this matter is very ...
For several decades, physicists and astrophysicists have theorized about the existence of dark matter in the universe. This elusive type of matter would be made up of particles that do not absorb, reflect or emit light, and ...
How do you observe a process that takes more than one trillion times longer than the age of the universe? The XENON Collaboration research team did it with an instrument built to find the most elusive particle in the universe—dark ...

(Phys.org)—Xenon, one of the noble gases, forms oxides that are not stable under ambient conditions, but are stable under very high pressure. In an effort to understand why the Earth's crust and atmosphere lacks the expected ...
When nuclear fuel gets recycled, the process releases radioactive krypton and xenon gases. Naturally occurring uranium in rock contaminates basements with the related gas radon. A new porous material called CC3 effectively ...
