Quantum heat pump: A new measuring tool for physicists

Physicists from TU Delft, ETH Zürich and the University of Tübingen have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency ...

New spin amplifier accelerates search for dark matter

Despite astrophysical evidence for the existence of dark matter, direct detection of its interaction with particles and fields of the standard model has not been achieved. Illuminating dark matter is the best hope of making ...

Detecting mid-infrared light, one photon at a time

For some 30 years, scientists have used superconducting materials to record the tiniest specks of light imaginable—individual photons, or single particles of light. However, these detectors, which consist of ultracold wires ...

No trace of dark matter in gamma-ray background

Researchers from the University of Amsterdam's (UvA) GRAPPA Center of Excellence have just published the most precise analysis of the fluctuations in the gamma-ray background to date. By making use of more than six years ...

NA64 hunts the mysterious dark photon

One of the biggest puzzles in physics is that eighty-five percent of the matter in our universe is "dark": it does not interact with the photons of the conventional electromagnetic force and is therefore invisible to our ...

Closer look at microorganism provides insight on carbon cycling

Some of the world's tiniest organisms may have a large impact on climate change. Researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Tennessee found that microorganisms called ...
