Measuring times in billionths of a billionth of a second

How fast do electrons inside a molecule move? Well, it is so fast that it takes them just a few attoseconds (a billionth of billionth of a second) to jump from one atom to another. Blink and you missed it—millions of billions ...

Elegant hierarchical fiber organization within the bamboo node

In a study recently published in National Science Review, researchers used multiscale imaging techniques (including optical microscope, X-ray microscope (micro-CT), scanning electron microscope, and atomic force microscope, ...

How photoelectrodes change in contact with water

Photoelectrodes based on BiVO4 are considered top candidates for solar hydrogen production. But what exactly happens when they come into contact with water molecules? A study in the Journal of the American Chemical Society ...

Earth's oldest stromatolites and the search for life on Mars

The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to advanced ...

Researchers determine three-dimensional structure of PAPP-A

Danish researchers have determined the three-dimensional structure of the proteolytic enzyme PAPP-A. The results may allow us to better understand the basic biology that regulates linear growth of vertebrates. The same regulatory ...
