First results from new detector reveal detailed properties of subatomic ‘soup’ that mimics the early universe

By teasing out signatures of particles just tenths of a millimeter from the center of a trillion-degree fireball that mimics the early universe, nuclear physicists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and from other sites are gaining new insights about fundamental physics. They achieved this by smashing together gold nuclei at the Relativistic Heavy Ion Collider (RHIC). (more…)

UCLA researchers are first to directly measure division of cardiomyocytes

Researchers from UCLA’s Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research are the first to directly measure the division of heart muscle cells, proving that while such division is very rare, it does occur.

The study, conducted by assistant professor of cardiology Dr. Reza Ardehali and colleagues, resolves a recent controversy over whether the heart muscle has the power to regenerate itself. The findings are also important for future research that could lead to the regeneration of heart tissue to repair damage caused by disease or heart attack. (more…)
