8 Molecule Detected From The ‘Dawn Of Chemistry’
After decades of scouring the cosmos, experts have successfully detected the compound helium hydride, thought to be the first molecule formed in the history of the universe. Due to the obstructive effects of the Earth’s atmosphere, researchers decided to take to the skies to make their landmark discovery. The Stratospheric Observatory for Infrared Astronomy, an airborne observatory built into a modified Boeing 747, was able to pick up infrared signals emanating from the prehistoric molecule.
In a period dubbed the “dawn of chemistry,” around 100,000 years after the Big Bang, the universe had cooled to a low enough temperature that particles began to interact and coalesce. In this era, when light atoms and molecules first came into being, it was helium hydride that paved the way for far more intricate interstellar structures to come. By continuing to investigate the elusive molecule, researchers are able to explore the expansion of the universe in its nascent stages.
7 New Species Of Primitive Human Discovered
Another strand has been added to the history of human evolution. Remnants of an extinct relative have been found in Callao Cave on the island of Luzon in the Philippines. The primitive species, known as Homo luzonensis, is said to have resembled modern humans in some respects but in others was closer to our ancient ape-like ancestors. On top of that, they are thought to have been competent climbers, as indicated by the curved bones in their fingers and toes.
The discovery poses a number of questions about the long and complex history of our species. With only 13 teeth and bones on which to base their hypotheses, experts remain in the dark as to how Homo luzonensis came to be on the island in the first place. Furthermore, the species’ features suggest that our ancient ancestors made the journey out of Africa to Southeast Asia, an idea which contradicts current historical theories.
