First Results from Penn's Balloon-Borne Telescope BLAST: Extragalactic Survey Reveals Half the Universe's Starlight

PHILADELPHIA –- After two years spent analyzing data from BLAST, the Balloon-borne Large-Aperture Sub-millimeter Telescope, physicists are releasing the first results.

The study, published in the current issue of Nature, reveals that the Far Infrared Background, or FIRB, originates from individual galaxies some 7 to 10 billion light years away.

Penn Biologists Discover How "Silent" Mutations Influence Protein Production

PHILADELPHIA -– Biologists at the University of Pennsylvania have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones. The new research, which involved creating hundreds of synthetic green-glowing genes, provides an explanation for how a cell “knows” how much of each protein to make, providing just the right amount of protein to maintain homeostasis yet not too much to cause cell toxicity.
