Physicists Demonstrate Existence of Tetraneutron

An Iowa State University-led team of physicists has demonstrated the quasi-stable existence of a tetraneutron, a subatomic structure once thought unlikely to exist. Tetra-neutron system produced in double-charge exchange reaction 4He(8He,8Be). Image credit: Susumu Shimoura / University of Tokyo. On their own, neutrons are very unstable and will convert into …

Physicists Demonstrate Existence of Two States of Liquid Water

There are two states of liquid water, says an international team of physicists led by Oxford University’s Dr. Laura Maestro. L.M. Maestro et al find that two states of liquid water play an important role in the thermal and optical properties of nanomedical systems; the team’s preliminary findings also suggest …

Physicists Observe Butterfly Rydberg Molecule for First Time

An international team of physicists, led by Prof. Chris Greene from Purdue University and Prof. Herwig Ott from the University of Kaiserslautern, has observed a butterfly Rydberg molecule, a weak pairing of two highly excitable atoms. Their work was published in the Oct. 5 issue of the journal Nature Communications …

Scientists are closing in on turning hydrogen into a metal

Like modern day alchemists, scientists are attempting to transform a common element into a precious metal. This isn’t about making lead into gold, but turning elemental hydrogen into a different, never before seen form of hydrogen. Scientists are tantalizingly close to producing the first samples of solid metallic hydrogen using …
