  La Jolla CA (SPX) Sep 18, 2019 For decades, chemists have tested theories for how life began on Earth. One hypothesis has caught the scientific imagination for years: RNA World. This theory proposes that prebiotic molecules joined up early on to form RNA, the molecules that carry instructions from DNA in organisms today. RNA World posits that once RNA formed on Earth, it began replicating itself and later gave rise to molecules like DNA. RNA World is a fascinating theory, says Ramanarayanan Krishnamurthy, PhD, an associate prof ... read more |

 Albuquerque NM (SPX) Sep 12, 2019 
Experimenting at 2.2 million degrees Celsius, physicists at Sandia National Laboratories' Z machine have found that an astronomical model - used for 40 years to predict the sun's behavior as well as the life and death of stars - underestimates the energy blockage caused by free-floating iron atoms, a major player in those processes.
The blockage effect, called opacity, is an element's natu ... more |

 Washington (UPI) Aug 30, 2019 
Stone tools recovered from an archaeological dig in western Idaho suggest humans were living in the region at least 16,000 years ago, 1,000 years earlier than previously thought.
The discovery, published Friday in the journal Science, supports the theory that the earliest human migrations into the Americas followed a Pacific coastal route, not an inland ice-free corridor.
