MIT physicists devise molecular technique to probe atomic nuclei
Physicists at MIT have developed a new method using molecules to investigate the interior of atomic nuclei, employing electrons as messengers in a tabletop setup. By studying radium monofluoride, they detected subtle energy shifts indicating electron interactions inside the nucleus. This approach could help explain the universe's matter-antimatter imbalance.
Physicists narrow down strong nuclear force critical point

Researchers have made progress in identifying a critical point where the strong nuclear force weakens, allowing quarks and gluons to form a hot plasma. By analyzing collisions at a New York particle accelerator, scientists have narrowed the possible location of this point on a phase diagram. This finding could reveal insights into the early universe and neutron stars.
Scientists develop new method for dark matter detection
Researchers have announced a breakthrough in detecting elusive dark matter particles using advanced collider technology. The discovery, detailed in a recent Nature publication, could reshape our understanding of cosmic composition. Led by a team at CERN, the method promises more precise measurements than previous attempts.
Physicists measure trillion-degree heat in Big Bang plasma
Researchers at Rice University have captured the temperature profile of quark-gluon plasma, the ultra-hot matter from the universe's dawn. By analyzing electron-positron emissions from atomic collisions, they determined precise temperatures at different evolutionary stages. The findings, published in Nature Communications, refine understanding of early cosmic conditions.
