Dark matter detector observes rarest event ever recorded

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 ...

South Pole Neutrino Detector Could Yield Evidences of String Theory

Researchers at Northeastern University and the University of California, Irvine say that scientists might soon have evidence for extra dimensions and other exotic predictions of string theory. Early results from a neutrino ...

R&D 100 award for inexpensive gamma ray detector device

Douglas S. McGregor and Walter McNeil have a philosophy: use clever methods to keep things simple. "You can always add more circuitry to make things complex, but that is just more to break down," McGregor said. "If we keep ...

The first observation of neutrinos at CERN's Large Hadron Collider

Neutrinos are tiny and neutrally charged particles accounted for by the Standard Model of particle physics. While they are estimated to be some of the most abundant particles in the universe, observing them has so far proved ...

LIGO surpasses the quantum limit

In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes.

Which-way detector unlocks some mystery of the double-slit experiment

(PhysOrg.com) -- One of the greatest puzzles of the double-slit experiment – and quantum physics in general – is why electrons seem to act differently when being observed. While electrons traveling through a barrier ...

Scientists confirm thermonuclear fusion in a sheared-flow Z-pinch device

In findings that could help advance another "viable pathway" to fusion energy, research led by Lawrence Livermore National Laboratory (LLNL) physicists has proven the existence of neutrons produced through thermonuclear reactions ...

Gravitational waves detected 100 years after Einstein's prediction

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's ...
