A definitive geological timeline from Princeton University researchers shows that a series of massive eruptions 66 million years ago in a primeval volcanic range in western India known as the Deccan Traps played a role in the extinction event that claimed Earth's non-avian dinosaurs, and challenges the dominant theory that a meteorite impact was the sole cause of the extinction.

New Timeline Confirms Ancient Volcanism Aligned With Dinosaurs’ Extinction

A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth’s non-avian dinosaurs, according to new research from Princeton University. A primeval volcanic range in western India known as the Deccan […]

Do You Speak Cow? Researchers Listen To ‘Conversations’ Between Calves And Their Mothers

Researchers have been eavesdropping on ‘conversations’ between calves and their mothers — measuring the process of how cows communicate using detailed acoustic analysis for the first time. The team from The University of Nottingham and Queen Mary University of London, spent ten months studying to the ways cows communicate with their young, carefully examining acoustic […]

Swarms Of Pluto-Size Objects Kick Up Dust Around Adolescent Sun-Like Star

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun. By making detailed observations of the protoplanetary disk surrounding the star known as HD 107146, the astronomers detected an unexpected increase in the concentration of […]

Major Viking Hall Identified In Sweden

A Viking feasting hall measuring almost 50 metres in length has been identified near Vadstena in Sweden. Archaeologists from Stockholm University and Umeå University used ground-penetrating radar, a non-invasive geophysical method, to locate and map the house foundation. The Aska barrow, where the hall has been found, was long seen as a burial mound. But […]

The Thoughts Of Our Ancient Ancestors – OpEd

The discovery of what appear to have been deliberately etched markings made by a human ancestor, Homo erectus, on the surface of a shell, call for a reconsideration of assumptions that have been made about the origins of abstract thought. While the meaning of these zigzag markings will most likely remain forever unknown, it can […]

Spain To Invest 344.5 Million Euros In Space Programs

At the Ministerial Council of the European Space Agency (ESA) held in Luxembourg earlier Wednesday, the Spanish delegation – led by the Secretary-General for Industry and SMEs, Begoña Cristeto, and the Managing Director of the Centre for Industrial and Technological Development (Spanish acronym: CDTI), Elisa Robles – announced that Spain will invest 344.5 million euros […]
