Phase transitions in the collective motions of self-propelled particles are directly impacted both by the initial velocity of ...

UT Southwestern researchers discovered that small HDL particles are linked to greater gray matter volume and better cognitive ...

The same number of particles are spread further apart than in the liquid or solid states. The same mass takes up a bigger volume - this means the gas is less dense. Density also depends on the ...

Researchers at UT Southwestern Medical Center have uncovered a new role for high-density lipoprotein (HDL), often called “good” cholesterol, in protecting brain health during middle age. The study, ...
