Princeton scientists discover chiral crystals exhibiting exotic quantum effects .
Princeton physicist Zahid Hasan led an international team of physicists who have discovered a form of chiral crystals — crystals with an asymmetry like biological “handedness” — that host slow light-like massless electrons. The movement of some groups of electrons in these crystals mimics the behavior of magnetic monopoles. These strange properties may be utilized for next-generation quantum, magnetic and optical technologies.
Speed limit on DNA-making sets pace for life's first steps .
Researchers led by Princeton’s Stanislav Shvartsman have found that the DNA of fruit fly embryos must obey a natural speed limit when it comes to replicating their genomes. Eggs with a mutation that allow for overproduction of DNA end in catastrophic failure at the moment they would begin to take shape.
Algal library lends insights into genes for photosynthesis .
To identify genes involved in photosynthesis, a team led by Princeton researchers has built a library containing thousands of single-celled algae, each with a different gene mutation.
Astronomers discover 83 supermassive black holes in the early universe>
