Breaking: Scientists Create World's First Nuclear Clock

A huge breakthrough decades in the making was made just a few months ago, and already scientists are realizing its potential: A measurement of the gap between the quantum energy states of a thorium nucleus has been used to create the very first, rud…

A Merick Physicist is Building a Case for Scrapping Quantum Gravity

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of physicists have spent their careers working to build a…

“Nothing” Doesn’t Exist. Instead, There Is “Quantum Foam”

When you combine the Uncertainty Principle with Einstein's famous equation, you get a mind-blowing result: Particles can come from nothing. What is nothing? This is a question that has bothered philosophers as far back as the ancient Greeks, whe…

All Of The Bases In DNA And RNA Have Now Been Found In Meteorites

More of the ingredients for life have been found in meteorites. Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report April 26 in  Nature Communications . These “nucleo…

Scientists Reverse Arrow of Time in Quantum Experiment

Physicists refer to this idea as the “arrow of time,” and the idea of unidirectional time seems to hold true for life and objects on a human scale. But on a quantum scale, things seem to work differently, even strangely. For physicists, the arrow of…
