Study finds alligator hearts keep beating no matter what
A new study reported by Georgia Tech researchers finds that an alligator heart will not fibrillate when exposed to drastic temperature changes, unlike a rabbit (mammal) heart, which is critically vulnerable to heart trauma under those conditions.

Quantum causal loops
Causal reasoning is ubiquitous - from physics to medicine, economics and social sciences, as well as in everyday life. Normally, causal influence is assumed to only go one way - from cause to effect - and never back from the effect to the cause: the ringing of the bell does not cause the pressing of the button that triggered it. Now researchers have developed a theory of causality in quantum theory, according to which cause-effect relations can sometimes form cycles. (2021-02-09)
