Quantum Entanglement Experiment to Take Place Aboard the International Space Station

Quantum Entanglement Experiment to Take Place Aboard the International Space Station

Research on quantum entanglement is posed to make yet another leap forward as European researchers outline an experiment involving the International Space Station. Quantum entanglement, what Einstein termed “spooky action over a distance,” has remained puzzling to physicists since it was first predicted in the early years of quantum theory...

DUJS 13W Issue Online!

Dear Reader, Conflict and decay are found throughout the natural world. For instance, organisms must compete with one another for limited environmental resources while decay enables a breakdown of organic materials into their basic components to be reincorporated into living organisms. However, the theme of “Conflict and Decay” can also...

 
 

The Architecture of Motivation

A team of geologists from the University of Oslo in Norway recently found evidence of a lost subcontinent under the Indian Ocean. The submerged landmass allegedly sunk during the break-up of the prehistoric supercontinent Rodinia, which once joined India and Madagascar 85 million years ago (1). Geologist Bjørn Jamtveit and...
