A new analysis of collisions conducted at different energies at the Relativistic Heavy Ion Collider (RHIC) shows tantalizing signs of a critical point--a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from one phase to another. The findings will help physicists map out details of these nuclear phase changes to better understand the evolution of the universe and the conditions in the cores of neutron stars.
Texas A&M University researchers have recently shown superior performance of a new oxide dispersion strengthened (ODS) alloy they developed for use in both fission and fusion reactors.
New computer simulation forecasts a surprisingly optimistic heat load for future fusion facilities designed to harvest on Earth the fusion that powers the sun and stars to generate electricity.
Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants.
A new study published in EPJ D by Garston Tiofack, Faculty of Sciences, University of Marousa, Cameroon, and colleagues, assesses the dynamics of positron acoustic waves (PAWS) in EPI plasmas whilst under the influence of magnetic fields, or magnetoplasmas.
While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe. Now, researchers hunting for these squeezed protons have come up empty-handed, suggesting there's more to the phenomenon than first thought. The result was recently published in Physical Review Letters.
A team from the Institute for Nuclear Physics at the Technical University of Darmstadt has contributed to an international research collaboration aiming to clarify the way the angular momentum („spin") of the two fragments, resulting from the splitting of an atomic nucleus, is generated. The main result pulished now in „Nature": the fragments rotate only after the scission.
The 10 year anniversary of the Fukushima Daiichi nuclear accident occurs in March. Work just published in the Journal 'Science of the Total Environment' documents new, large (> 300 micrometers), highly radioactive particles that were released from one of the damaged Fukushima reactors.
A new study led by researchers at the UCLA Jonsson Comprehensive Cancer Center helps identify which patients with prostate cancer will benefit most from the use of prostate-specific membrane antigen PET imaging, PSMA PET, a novel imaging technique that recently was approved by the U.S. Food and Drug Administration.
A novel computer algorithm, or set of rules, that accurately predicts the orbits of planets in the solar system could be adapted to better predict and control the behavior of the plasma that fuels fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars.
