Spinel, MgAl 2 O 4 (download cif), is a rare gemstone that was used to imitate rubies. The structure has face-centered cubic symmetry, and is a little heavy to understand. The general formula is AB 2 ...

A keystone in an arch's crown secures the other stones in place. Keystone species play the same role in many ecological communities by maintaining the structure and integrity of the community.

The Earth is currently experiencing its sixth major extinction event. One million species globally are at risk of extinction in the next few decades, including 27 percent of the world’s mammals, 41 ...

But there's more to this unexpected mutualistic relationship than that. These species of spider and frog have been found in the same area, and even share the same burrows. The frogs use the ...

Scientists expect even more new species to emerge from the region. Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international ...

De-extinction — the science of resurrecting extinct species — is progressing in leaps and bounds. Here are six creatures that researchers could bring back to life. De-extinction starts with ...

How do new species form? Like most areas of Evolutionary Biology, research related to the formation of new species - 'speciation ' - is rich in historical and current debate. Here, we review both ...

A species is a distinct group of organisms and the most basic unit used to measure life on Earth. However, there’s no single definition of a species, meaning this vital concept in biology can be ...

In nature, species will sometimes form unexpectedly close bonds and work to their mutual benefit. Symbiotic relationships are the close associations formed between pairs of species. They come in a ...

By focusing on spinel cobalt oxides, a research team has revealed how understanding and optimizing these catalysts could offer a solution to this challenge. Researchers have made a significant ...

An international team of researchers delved into museum collections and discovered new species of sponge-associated zoantharian, a small colonial organism similar to anemones. Dr. Javier ...
