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

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 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 ...

The birth of a 'snowman' at the edge of the solar system

A model developed at the Faculty of Physics at the Technion, in collaboration with German scientists at Tübingen, explains the unique properties of Arrokoth, the most distant object ever imaged in the solar system. The research ...
