Zschau, GSI Enlarge It sounds like science fiction, but the time you experience between two events depends directly on the path you take through the universe. In other words, Einstein’s theory of special relativity postulates that a person traveling in a high-speed rocket would age more slowly than […]

Greenland Ice Sheet more vulnerable to climate change than previously thought

A scientist explores the remains of a supraglacial lake after it has drained. Credit: Sam Doyle Enlarge A new model developed by researchers at the University of Cambridge has shown that despite its apparent stability, the massive ice sheet covering most of Greenland is more sensitive to climate change than earlier estimates have suggested, which […]

Climate change appears a mixed bag for a common frog

Scientists have found amphibians worldwide are breeding earlier due to climate change, but how that affects species is just now being answered. After warm winters, wood frogs in the wild breed earlier and produce fewer eggs.
