A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins of an unusual "zebra" pattern seen in high-frequency radio pulses from the Crab Nebula.

Now, a study presents a new theoretical model capable of overcoming the limitations of previous methodologies to understand how water behaves in extreme conditions.

"The combination of experimental results and theoretical insights provides a comprehensive picture of how magnetic fields can enhance catalytic performance," added Li, "This can serve as guidance when designing new catalysts in the future."

The rising threat is theoretical, until it isn’t.

“An extreme abortion ban is not theoretical to us,” said Lisa Turner, who guides a political action committee promoting Democratic candidates and causes.
