HD+ molecular ions (yellow and red pairs of dots: proton and deuteron; the electron is not shown) suspended in an ultra-high vacuum between atomic ions (blue dots), which are immobilized using a laser beam (blue). An electromagnetic wave (red-brown discs) causes the molecular ions to rotate. A further laser beam […]

A view of the underground ALICE detector used in the study of the antideuteron Credit: CERN The ALICE collaboration has presented new results on the production rates of antideuterons based on data collected at the highest collision energy delivered so far at the Large Hadron Collider. The antideuteron is composed […]

A photomultiplier tube array that is part of the LUX-ZEPLIN experiment at the Sanford Underground Research Facility in Lead, South Dakota. The photomultiplier tubes are designed to detect signals produced by dark matter particle interactions.

Bose-Einstein condensate comagnetometer, formed by two distinct atomic internal states of 87Rb which are contained in the same spatial wavefunction. Credit: ICFO/ P. Gomez & M. Mitchell Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be “dark matter,” which […]

UC Riverside physicists demonstrate ‘self-interacting dark matter’ model can be tested using astronomical observations of Draco and Fornax. A research team led by physicists at the University of California, Riverside, reports tiny satellite galaxies of the Milky Way can be used to test fundamental properties of “dark matter” — nonluminous material thought […]

Electrons and positrons collide within the Belle II detector. Credit: ill./©: Belle II The Belle II experiment started about one year ago. Physical Review Letters has now published the initial results of the detector. The work deals with a new particle in the context of dark matter, which accounts for […]

The lower horizontal axis is the axion mass, the upper horizontal axis is the microwave frequency corresponding to the mass, and the vertical axis is the coupling constant of axion-to-photon conversion. Both axes are in logarithm scales. CAPP-8TB indicates the range of mass reported in this study. CAST indicates experimental […]

Astronomers have gotten creative in trying to trace the elusive cosmic web, the large-scale backbone of the cosmos. Researchers turned to slime mold, a single-cell organism found on Earth, to help them build a map of the filaments in the local universe (within 500 million light-years from Earth) and find […]
