- Key regulator of bone development identified
- 07 December 2016 — Loss of a key protein leads to defects in skeletal development including reduced bone density and a shortening of the fingers and toes -- a condition known as brachydactyly. The discovery was made by researchers at Penn State University who knocked out the Speckle-type POZ Protein (Spop) in the mouse and characterized the impact on bone development.
- Coral genomes reveal how populations rebound after environmental catastrophes
- 17 November 2016 — New genome-sequence data show that Caribbean corals that have survived mass-extinction events caused by environmental change can rebound and expand their populations. An international team of researchers, led by scientists at Penn State University, sequenced the genomes of three species of corals in the genus Orbicella and used the data to model the population histories of these corals over the past several million years.
- "Cosmic Whistle" Packs a Surprisingly Energetic Punch
- 14 November 2016 — Penn State University astronomers have discovered that the mysterious "cosmic whistles" known as fast radio bursts can pack a serious punch, in some cases releasing a billion times more energy in gamma-rays than they do in radio waves and rivaling the stellar cataclysms known as supernovae in their explosive power.
