Unconventional quasiparticles predicted in conventional crystals (Science)

By Staff An international team of researchers has predicted the existence of several previously unknown types of quantum particles in materials. The particles -- which belong to the class of particles known as fermions -- can be distinguished by several intrinsic properties, such as their responses to applied magnetic and electric fields. In several cases, … Continue reading Unconventional quasiparticles predicted in conventional crystals (Science)

Study Models How the Immune System Might Evolve to Conquer HIV (PLOS Genetics)

By Katherine Unger Baillie, courtesy of the University of Pennsylvania It has remained frustratingly difficult to develop a vaccine for HIV/AIDS, in part because the virus, once in our bodies, rapidly reproduces and evolves to escape being killed by the immune system. “The viruses are constantly producing mutants that evade detection,” said Joshua Plotkin, a … Continue reading Study Models How the Immune System Might Evolve to Conquer HIV (PLOS Genetics)

Role for enhancers in bursts of gene activity (Cell)

  https://youtu.be/ImCSE26g910 By Marisa Sanders for the Office of the Dean for Research A new study by researchers at Princeton University suggests that sporadic bursts of gene activity may be important features of genetic regulation rather than just occasional mishaps. The researchers found that snippets of DNA called enhancers can boost the frequency of bursts, … Continue reading Role for enhancers in bursts of gene activity (Cell)
