Researchers discover chemical evidence for pair-instability supernova from a very massive first star
The first stars illuminated the universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos......»»
New strategy can harvest chemical information on rare isotopes with a fraction of the material
Studying radioactive materials is very difficult due to the potential health risks they pose to scientists. Expense is also a major barrier, with some radioisotopes costing more than $10,000 per microgram (or $10 billion per gram). Some radioisotopes.....»»
