A quantum “mini universe” made from ultracold atoms revealed that time can emerge from entropy changes inside a system, offering experimental insight into one of physics’ deepest mysteries. A scientist at the University of Birmingham has created a “mini universe” that could help answer one of science’s most fundamental questions: What is time? In a [...]

Remote Scottish islands turned tiny wrens into giant birds that may be evolving into new species. Tiny wrens living on remote Scottish islands are providing scientists with a rare look at how evolution can reshape animals in isolated environments. A new study led by researchers at the University of Birmingham found that several island populations [...]
