Fewer rainy days lead to earlier spring in northern climes

The total number of rainy days each year is contributing to an early arrival of spring for plants in northern climates. Scientists know that warmer temperatures have led to the first leaves coming out at earlier dates in recent decades. A new study found out...

Biologists investigate smallest propeller on Earth

University of Exeter scientists have discovered new information about the tiny propellers. These tiny propellers have been used by single-cell organisms called archaea. Archaea are found in a vast range of habitats, like bacteria. These includes human bodies. But unlike bacteria they do not cause...

Seed production of trees affect how trees are migrating due to climate change

A new study provided key insights into how and why tree populations migrate in response to climate change at the continental scale. Suitable habitats for forest trees are shifting fast with recent climate change. Most tree species in North America have shown evidence for northward...

New fuel cells can operate at temperatures between -20 to 200°C

Proton exchange membrane fuel cells are power cells. It can transform the chemical energy produced in the time of electrochemical reaction between hydrogen and oxygen into electrical energy. These cells are highly promising energy solutions. They operate at limited temperature ranges like 80 to...
