Cuba has been gripped by an outbreak of the viral disease chikungunya, as it battles shortages of clean water, food, fuel and medicine, during its worst economic crisis in decades.
Phys.org / Physicists demonstrate the constancy of the speed of light with unprecedented accuracy
In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in the direction of Earth's ...
Phys.org / A drying-up Rio Grande basin threatens water security on both sides of the border
One of North America's longest rivers, the Rio Grande—or Rio Bravo as it's called in Mexico—has a history as deep as it is long. Indigenous people have tapped it for countless generations, and it was a key artery for ...

Phys.org / How dark energy changed cosmology forever
Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his general theory of relativity. It was a masterpiece, giving us our modern-day view of the gravitational ...
Phys.org / Humans are evolved for nature, not cities, say anthropologists
A new paper by evolutionary anthropologists Colin Shaw (University of Zurich) and Daniel Longman (Loughborough University) argues that modern life has outpaced human evolution. The study suggests that chronic stress and many ...
