Radiation from Early Universe Found Key to Answer Major Questions in Physics

by University of California - San Diego
Astrophysicists at UC San Diego have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide an important cosmological test of Einstein’s theory of general relativity. These measurements have the potential to narrow down the estimates for the mass of ghostly subatomic particles known as neutrinos.

Biologists Discover Solution to Problem Limiting Development of Human Stem Cell Therapies

Biologists at UC San Diego have discovered an effective strategy that could prevent the human immune system from rejecting the grafts derived from human embryonic stem cells, a major problem now limiting the development of human stem cell therapies. Their discovery may also provide scientists with a better understanding of how tumors evade the human immune system when they spread throughout the body.
