Silver nanocatalysts switch reaction sites between power generation and hydrogen production‎

For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding introduces a new design principle for improving the performance of next-generation solid oxide cells.

One million years without sex fails to erase stick insects' unused biological system‎

Scientists have made a surprising finding about how an asexually reproducing stick insect has evolved. Research led by Dr. Darren Parker, lecturer in evolutionary biology at Bangor University, studied the genes of several species of Timema (a type of stick insect), which have not engaged in sexual reproduction for 1 million years—the longest known asexual period for any insect.
