Two-meter COVID-19 rule is 'arbitrary measurement' of safety

A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-meter rule was a number chosen from a risk 'continuum', rather than any concrete measurement of safety.

Memetics and neural models of conspiracy theories

Multitude of conspiracy theories people believe in all over the world is astonishing. They actually accompany each significant event: a catastrophe, assassination, death of a famous person or, currently, the COVID-19 pandemic. ...

Electromagnetic anomalies that occur before an earthquake

It has been documented over hundreds of years that various electromagnetic anomalies occur a few weeks before the occurrence of a large earthquake. These electromagnetic anomalies are variations that appear in telluric current, ...

What does a 1.5-degree warming limit mean for China?

As part of the Paris Agreement, nearly all countries agreed to take steps to limit the average increase in global surface temperature to less than 2 degrees C, or preferably 1.5 degrees C, compared with preindustrial levels. ...

The mysterious luminescence phenomena of earthquake lightning

Were you aware that earthquakes are sometimes associated with luminescence, called earthquake lightning? This phenomenon had been documented throughout history, such as between 1965 and 1967, the Matsushiro earthquake swarm ...

The cascade to criticality

Combined theoretical and experimental work has resulted in a novel mechanism through which criticality emerges in quasiperiodic structures—a finding that provides unique insight into the physics on the middle ground between ...
