| Scientists discover possible building blocks of ancient genetic systems in Earth's most primitive organisms Posted: 10 Nov 2012 06:35 AM PST A team of scientists announced that they have discovered AEG within cyanobacteria, which are believed to be some of the most primitive organisms on Earth. AEG is a small molecule that when linked into chains forms a hypothetical backbone for peptide nucleic acids, which have been theorized as the first genetic molecules.  |
| Mysteries of the neutrino: Physicists investigate the Big Bang particle Posted: 09 Nov 2012 08:13 AM PST Physicists at some of the world's leading research institutes are attempting to unravel the mysteries of a particle that played a role in the creation of the universe. The existence of neutrinos and anti-neutrinos -- particles that are almost massless and which travel at light speed from one side of Earth to the other -- was confirmed more than 50 years ago. Scientists believe that they were created at the Big Bang and might hold the key to the nature of the universe. But they are light particles that react weakly with matter and they change properties as they travel. This process -- named neutrino oscillation -- makes the particles highly elusive.  |
