Climate change and prehistoric human populations: Study finds eastward shift of settlement areas at end of last Ice Age

A new study sheds light on how prehistoric hunter-gatherer populations in Europe coped with climate changes over 12,000 years ago. Led by scientists from the University of Cologne, a team of 25 prehistoric archaeologists from twenty European universities and research institutions revealed significant shifts in population size and density during key periods at the end…

Twisted crystals open door to smaller, more powerful sensors for optical devices

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work? Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems.

Timid tinkerers: Shy mice are more persistent problem-solvers, study finds

Why do some animals solve problems while others don’t? The new study from the Max Planck Institute for Evolutionary Biology, now featured on the cover of Oikos, tackles this question with an unexpected star: the wild house mouse. This research dives into how different personality types—especially traits like boldness and shyness—influence innovation. Why do some animals…
